Answer: The graph is attached.
Step-by-step explanation:
1. Solve for y, as following:
[tex]10x+7y<49\\7y<-10x+49\\y<-\frac{10}{7}x+\frac{49}{7}\\\\y<-\frac{10}{7}x+7[/tex]
2. The equation of the line in slope intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
3. In this case the equation of the line is:
[tex]y=-\frac{10}{7}x+7[/tex]
then:
[tex]m=-\frac{10}{7}\\\\b=7[/tex]
4. Find the x-intercept. Make y=0. Then:
[tex]0=-\frac{10}{7}x+7\\\frac{10}{7}x=7\\x=4.9[/tex]
5. Then, plot the line that passes through the points (0,7) and (4.9, 0).
6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.
Then you obtain the graph attached.
Answer:
We need to graph the given inequality 10x + 7y < 49.
We can do that into 2 parts:
Part 1:
Graph the line 10x+7y=49
plug any number for x say x=0
10x+7y=49
10(0)+7y=49
0+7y=49
7y=49
y=49/7
y=7
hence it passes through point (0,7)
similarly plug y=0
10x+7(0)=49
10x=49
x=49/10
x=4.9
hence it passes through point (4.9,0)
Graph both points then join them by a straight dotted line because of < sign.
PART 2:
Shade the graph for inequality sign <
use any test point which is not on the given line say (0,0)
plug into original problem
10x + 7y < 49
10(0) + 7(0) < 49
0<49 is true
so shade in direction of test point
Hence final graph looks like:
What is the value of x so that the line segment with endpoints W(x, −2) and X(5, −4) is parallel to the line segment with endpoints Y(2, 2) and Z(5, 6)?
x equals six start fraction one over two end fraction
x = 6
x equals three start fraction one over two end fraction
x = 7
Answer:
x equals six start fraction one over two end fraction
Step-by-step explanation:
Segments which are parallel have the same slope. Find the slope of of YZ. Then using that value, find the slope WX and solve for the value of x.
Slope of YZ is:
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{6-2}{5-2} =\frac{4}{3}[/tex]
Since they are parallel, then WX has a slope of 4/3 too.
Slope of WX is:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\\frac{4}{3} = \frac{-4--2}{5-x}\\\\\frac{4}{3} =\frac{-2}{5-x}\\\\ (5-x)\frac{4}{3} = -2\\\\ 20 - 4x = -6\\\\-4x = -26 \\\\ x = 6 \frac{1}{2}[/tex]
the volume of a cylinder is 1,356.48^ feet. If the diameter is 12 feet, calculate the height of the cylinder.
Answer:
11.99 ft
Step-by-step explanation:
The formula for the volume of a cyl. of radius r and height h is V = πr²h.
Solving this immediately for h yields:
V
h = ----------
πr²
Inserting the known quantities results in:
V 1356.48 ft³
h = ---------- = ---------------------- Note that r = (1/2)d, so r = (1/2)(12 ft) = 6 ft
πr² 3.14159 (6 ft)²
= 11.994 ft
The height of the cyl. is 11.99 ft (to the nearest hundredth foot)
Final answer:
To find the height of the cylinder with a volume of 1,356.48 cubic feet and a diameter of 12 feet, divide the volume by the area of the base (calculated with a radius of 6 feet) to get approximately 11.99 feet.
Explanation:
To calculate the height of a cylinder when the volume and diameter are given, we use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height. In this case, we have a volume of 1,356.48 cubic feet and a diameter of 12 feet, meaning the radius is 6 feet (half of the diameter). So we can plug these values into our formula to solve for h.
First, calculate the area of the base (πr²): 3.14159 × (6 feet)² = 3.14159 × 36 = 113.0976 square feet. Then we divide the given volume by this area to find the height: 1,356.48 cubic feet / 113.0976 square feet = 11.99 feet. Therefore, the final answer for the height of the cylinder is approximately 11.99 feet.
What is the value of y in the product of powers below?
Answer:
y =0
Step-by-step explanation:
From the equation;
8³ × 8⁻⁵×8^y = 8⁻²= 1/8²
From the laws of indices;
aⁿ×aⁿ = a^2n
Therefore;
8³ × 8⁻⁵×8^y = 8^(3+-5+y)
8^(-2+y) = 8^-2 ; but the bases are the same and thus the exponents are the same;
-2 + y = -2
y = 0
Answer:
The value of y is 0
Step-by-step explanation:
8³ * 8^-5*8^y = 8^-2 or 1/8²
Taking indices of both sides
From first law of indices;
Multiplication sign change to addition; i.e. x^a * x^b = x^(a + b).
So,
8³ * 8^-5*8^y = 8^-2
Becomes
8^(3 + (-5) + y) = 8^-2
Same base of 8 can cancel one another. So, we're left with
3 + (-5) + y = -2
Open the bracket
3 - 5 + y = -2
-2 + y = -2
Make y the subject of formula
y = 2 - 2
y = 0
Hence, the value of y in the equation is 0
Which value for x makes the sentence true? 1/50+x=1/10
Answer:
2/25 is the Answer, as a decimal it is 0.08
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x + 1/50 = 1/10
Step 2: Subtract 1/50 from both sides.
x + 1/50 - 1/50 = 1/10 - 1/50
X = 2/25
Proof that it is the answer
0.02 + 0.08 = 0.1
0.02 is 1/50
0.08 is 2/25
0.1 is 1/10

What is the solution to the following system of equations?
Answer:
D. (2,1)
Step-by-step explanation:
Fill in the value for y from the first eq (6x-11) into the second:
-2x - 3(6x-11) = -7
Now simplify:
-2x -18x + 33 = -7
-20x = -7-33
20x = 40
x = 2
Now that we have x, plug it into the top eq to get y:
y = 6*2 - 11 = 1
Et voila, x=2 and y=1, so the solution is (2,1).

Is the point (-10, -34 ) on the line y=3x-4 Show how you know
Answer:
yes
Step-by-step explanation:
Substitute x = - 10 into the equation and if the value obtained equals - 34 then the point satisfies the equation and lies on the line
x = - 10 : y = (3 × - 10) - 4 = - 30 - 4 = - 34 ← agrees
Hence (- 10, - 34) lies on the line y = 3x - 4
Sarah Wood and her husband have agreed to purchase a house for $87,500.00. Washington Savings and Loan is willing to finance the purchase but requires a $5,000.00 down payment and closing costs of 3 percent of the amount of the mortgage loan. What are the total closing costs?
The mortgage loan amount is $82,500. The closing costs are 3 percent of the loan amount. Therefore, the total closing costs are $2,475.
Explanation:Sarah Wood and her husband are purchasing a house for $87,500.00, but they are making a down payment of $5,000.00. Therefore, the mortgage loan amount is $87,500 - $5,000 = $82,500. The closing cost for this mortgage loan is 3 percent of the loan amount. Thus, to calculate the total closing costs, we multiply the loan amount by 3%. Therefore, total closing costs are $82,500 * 0.03 = $2,475.00.
So, total closing costs are $2,475.00.

(x^(2))/(9)+(y^(2))/(49)=1 The distance from the center to the major intercept is
Answer:
7
Step-by-step explanation:
This is an equation of an ellipse of the form:
[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]
Where a and b are the minor and major intercepts, given a<b
In this question, a<b and a = 3 and b = 7
The distance from the center to the major intercept is b, thus the distance we are seeking for is 7
Answer:
b = 7 units.
Step-by-step explanation:
The given equation of the ellipse is
[tex]\frac{x^{2} }{9} +\frac{y^{2} }{49}=1[/tex]
As we know in an ellipse [tex]\frac{x^{2} }{a^{2} }+ \frac{y^{2} }{b^{2}}=1[/tex]
a will be major axis and b is the minor axis when ( a > b )
In the given equation 49 > 9 ⇒ b² > a²
so major axis will be = √49
= 7
Therefore, distance from center to the major intercept is b = 7 units.

Answer:
5.94x10^1
Step-by-step explanation:
In scientific notation all numbers are written in the form of m×10n (m times ten raised to the power of n), where the exponent n is an integer, and the coefficient m is any real number, called the significand or mantissa. If the number is negative then a minus sign precedes m (as in ordinary decimal notation).
the sum of two numbers is 17. one number is 3 less than 2/3 of the other number. what is the lesser number?
the lesser number is 5.
steps:Let the first number = x
Let the second number = y
set up two equations
x + y = 17
2/3 x -3 = y
sub the second equation into the first one
x + 2/3 x - 3 = 17
collect like terms (1x = 3/3 x)
5/3 x - 3 = 17
add 3 to both sides
5/3 x = 20
multiply by 3 on both sides
5x = 60
divide by 5 on both sides
x = 12
sub back in one of the equations and solve to find the other number:
x + y = 17
12 + y = 17
y= 5
the lesser number is 5•have a good day• :) ~ ♡lipika♡
The lesser number is 5.
Let us consider that first number is x .
Since, second number is 3 less than 2/3 of the other number.
So that, second number [tex]=\frac{2}{3}x-3[/tex]
The sum of both number is 17.
[tex]x+\frac{2}{3}x-3=17\\\\\frac{5}{3}x=17+3\\\\\frac{5}{3}x=20\\\\x=20*\frac{3}{5}=12[/tex]
Lesser number is. [tex]=\frac{2}{3}x-3=\frac{2}{3}*12-3=5[/tex]

Answer:
4
Step-by-step explanation:
You can divide all the x from the y like , 45/9 =4 so it equals four
Yes, the table does show a proportional relationship and the constant of proportionality is 4.
What is proportionality?If the corresponding elements of two sequences of numbers have a constant ratio,
Known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.
We know constant of proportionality is when we have the same multiplicative or division factor between two variables.
Given, when x = 3, y = 12, So y = 4x.
Again when x = 6 , y = 24, so, y = 4x and from observation we can conclude that y is 4 times of x or y = 4x.
∴ The constant of proportionality is 4.
