The linear equation x = -2 will be parallel to the x-axis.
True
False
Answer:
False
Step-by-step explanation:
The equation x = c represents the equation of a vertical line parallel to the y- axis.
The equation y = c represents the equation of a horizontal line parallel to the x- axis
In both cases c is a constant
Hence x = - 2 is not parallel to the x- axis

Answer:
The measure of angle x is [tex]64.4\°[/tex]
Step-by-step explanation:
To find the measure of angle X, apply the law of cosines
The law of cosines states that
[tex]c^{2}=a^{2}+b^{2}-2(a)(b)cos(C)[/tex]
In this problem we have
[tex]a=19\ cm[/tex]
[tex]b=25\ cm[/tex]
[tex]c=24\ cm[/tex]
[tex]C=x\°[/tex]
substitute
[tex]24^{2}=19^{2}+25^{2}-2(19)(25)cos(C)[/tex]
[tex]576=986-950cos(C)[/tex]
[tex]cos(C)=(986-576)/950[/tex]
[tex]C=arccos[(986-576)/950]=64.4\°[/tex]
Therefore
The measure of angle x is [tex]64.4\°[/tex]
A set of data with a mean 56 and a standard deviation 3.3 is normally distributed. find 2 standard deviations from the mean
Answer:
To the right we have 62.6 while to the left we have 49.4
Step-by-step explanation:
A normal distribution is usually symmetric with respect to the mean. The mean of the distribution is also the mode as well as the median.
The general formula for points that lie n standard deviations away from the mean on either sides of the mean is given by the formula;
mean ± n(σ)
where σ is the standard deviation of the distribution;
Two standards deviations from the mean imply that n = 2;
56 ± 2(3.3)
56 ± 6.6
To the right we have 62.6 while to the left we have 49.4

select the best definition for congruent (A same size) (B same shape but not necessarily the same size) (C same size not necessarily same shape) (D same size and same shape)
Answer:
(D same size and same shape)
Step-by-step explanation:
Congruent means the same size and shape.
Similar means the same shape, but not necessarily the same size
Answer:
The answer is : (D same size and same shape)
Step-by-step explanation:
Two shapes or figures are called congruent, when they are identical. When the angles are equal in degrees, they are called congruent angles and when sides are congruent, this means they have the same length.Two polygons are congruent if they have the same size and shape or if their corresponding sides and angles are equal.
Therefore, option D is correct.
Find an equation, in slope-intercept form, that passes through point (-5, 6) with slope -2.
Select one:
a. y = -2x + 3
b. y = -2x - 4
c. y = 2x - 4
d. y = 2x + 3
Answer:
The desired equation is y = -2x - 4
Step-by-step explanation:
The general slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
Starting from that, substitute the given values for m, x and y and calculate b:
6 = -2(-5) + b. Then 6 = 10 + b, and b = -4.
The desired equation is y = -2x - 4.

The y-intercept is the value of y when the value of x is equal to zero
For x=0
[tex]y=-3.5(0+5)[/tex]
[tex]y=-17.5[/tex]
therefore
The y-intercept is the point (0,-17.5)
Use a net to find the surface area of the prism please help
Finding rectangle surface areas(RSA) are: 2(14×7)+2(14×5)=336
R.S.A+side surface areas: 336+2(7×5)=406
Ans:406
To find the surface area of a prism using a net, you simply calculate the area of each individual shape in the net and then add those areas together. The sum of these areas is the prism's surface area.
Explanation:To find the surface area of the prism using a net, you need to first understand what a net of a prism is. A net of a prism is essentially a 'flat' version of the shape. It's what you would get if you cut along the edges of the prism and flattened it out.
For a rectangular prism, for instance, the net would consist of 2 rectangles (the bases) and 3 or 4 rectangles (the sides), depending on whether the prism is a right prism or an oblique prism.
To find the surface area, calculate the area of each individual shape in the net and then add all those areas together. The sum of these areas is the surface area of the prism.
As an example, suppose we have a rectangular prism with length 4 cm, width 3 cm, and height 2 cm. The areas of the two bases are each 4*3=12 square cm. The areas of the four sides are two of 4*2=8 square cm and two of 3*2=6 square cm. So the total surface area is 2*12+2*8+2*6=48 square cm.

find the correct trigonometry formula to solve for X.
Answer:
The correct answer is last option
Cos(55) = 11/x
Step-by-step explanation:
Points to remember
Trigonometric ratios
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = opposite side/Adjacent side
From the figure we can see a right angled triangle, with one angle is 55 degree, one side is 11 and hypotenuse is x
To find the correct trigonometric formula
Here we have adjacent side of angle 55
Cos 55 = Adjacent side/Hypotenuse
Cos 55 = 11/x
Therefore the correct answer is last option
A grocery, a cafe, a boutique, and a dance studio have the addresses 500 Elm, 524 Elm, 538 Elm, and 544 Elm, but not necessarily in that order. The boutique is between the cafe and the studio. The studio has the highest address. The grocery is between the cafe and boutique.
Answer:
500 Elm: Cafe
524 Elm: Grocery
538 Elm: Boutique
544 Elm: Dance studio
Step-by-step explanation:
We know that the dance studio has the highest address, so 544.
For the others let's examine the possibilities.
The boutique is between the cafe and the studio, that means the following are possible:
Boutique can be at either 524 or 538, cannot be at 500 (since cafe has to be on the its left.
Cafe can be 500 or 524, cannot be 538 since boutique has to be between cafe and studio.
The grocery is between the cafe and boutique. Meaning the grocery cannot be 500 nor 538, since it has to be in the middle of the 3 remaining businesses. So, grocery is at 524.
Meaning the Cage is at 500 and the boutique is at 538.

=:
.
Answer:
30°
Step-by-step explanation:
Segment MP is the diameter of the circle, hence angle MOP has the measure of 180°.
Angles MON and NOP are supplementary angles (add up to 180°). Thus,
m∠MON+m∠NOP=180°
m∠MON=180°-m∠NOP
m∠MON=180°-150°=30°.
Angle MON is the central angle subtended on the arc MN. Thus, the measure of the arc MN is 30°.
Answer:
Arc MN is 30°Step-by-step explanation:
It's important to know that the whole arc of a circle is 360°.
So, if MP is a diameter, that means it divides the circle in two equal parts of 180° each.
Now, one half of this arc is formed by MN and 150°, so we can formulate the expression
[tex]MN+150\° = 180\° \\MN= 30\°[/tex]
Therefore, the arc MN is 30°.

We can solve this question using two methods :
Unitary MethodMethod of proportion[tex] \small\bf{ Unitary \: Method}[/tex]
20 workers can build a school in 18 days
1 worker can build a school in 20 × 18 days
12 workers can build a school in [tex]\dfrac{20 × 18 }{12}[/tex] = 30 days.
Hence the required number of days is 30.[tex] {{\rule{40mm}{4pt}}}[/tex]

the concession stand sells hot dogs for $3 and burger for $4. at last weeks football game, the stand sold 10 more hot dogs than burgers and made $184. write a system of equation to represent the situation
The system of equations to represent the concession stand sales situation is 3H + 4B = 184 for the total sales, and H = B + 10 for the quantity relationship, where H is the number of hot dogs sold, and B is the number of burgers sold.
To represent this situation with a system of equations, let's denote the number of hot dogs sold as H and the number of burgers sold as B. According to the problem, hot dogs are sold at $3 each and burgers at $4 each, and the stand made $184 in total. Also, we are told that 10 more hot dogs than burgers were sold at the game.
We can create two equations to represent this scenario:
The total sales equation: 3H + 4B = 184The quantity relationship equation: H = B + 10These two equations form the system that can be solved to find the number of hot dogs and burgers sold.

A square banner had 4 feet added its width and 2 feet subtracted from its height. The banner then had an area of 91 square feet. How long was a side of the original square banner?
Answer:
The length side of the original square banner was 9 ft
Step-by-step explanation:
Let
x-----> the length side of the original square banner
we know that
The new area of the banner is equal to
[tex]91=(x+4)(x-2)[/tex]
Solve for x
[tex]91=(x+4)(x-2)\\ \\91=x^{2}-2x+4x-8\\ \\x^{2}+2x-99=0[/tex]
Solve the quadratic equation by graphing
The solution is x=9 ft
see the attached figure
To determine the length of the original square banner, we can set up an equation using the given information and solve for the side length.
Explanation:To solve this problem, let's first represent the length of the original square banner as x. According to the question, 4 feet is added to the width, so the width becomes x + 4. Also, 2 feet is subtracted from the height, so the height becomes x - 2. The area of a square is calculated by multiplying the side lengths, so we have (x + 4)(x - 2) = 91.
Expanding the equation, we get x² + 2x - 8 = 91. Rearranging the equation, we have x² + 2x - 99 = 0. This is a quadratic equation that can be solved by factoring, completing the square, or using the quadratic formula.
By factoring, we find (x + 11)(x - 9) = 0. So, x = -11 or x = 9. Since we cannot have a negative length for a banner side, we discard x = -11. Therefore, the length of the side of the original square banner is 9 feet.

Answer:
1/4
Step-by-step explanation:
because if you use the process of breaking down the numbers they will end up going down to simplest form.
Answer:
3/12 = 1/4
Step-by-step explanation:
If we know 12 is equal to a fraction with the denominator of 4, we can divide 12 by 4 and get 3. This means we must also divide the numerator by 3 to get 3/3 = 1. Another way to solve this is to cross multiply. If 3/12 = _/4, we multiply the numerator of the first fraction by the denominator of the second fraction. Then, we get 12. Divide the 12 by the denominator of the first fraction to get 12/12. This will give you an answer of 1 as well.
