Answer:

8.3 * 10 ^5

Step-by-step explanation:

830000

To change this to scientific notation, we move the decimal 5 places to the left.  The exponent will be positive 5 because we moved it to the left

8.3 * 10^ +5

8.3 * 10 ^5

Answer:

x = z = 45°, y = 90°

Step-by-step explanation:

This is an isosceles triangle ( given 2 equal sides )

Hence x = z ( base angles )

z and 135° form a straight angle and are supplementary

z = 180° - 135° = 45°

hence x = z = 45°

the sum of the 3 angles in the triangle = 180°

To find y subtract the sum of x and z from 180

y = 180° - (45 + 45)° = 180° - 90° = 90°

[tex]\bf -5x+2\geqslant -48\implies -5x \geqslant -50\implies \stackrel{\textit{now, we're dividing by -5}}{\cfrac{-5x}{-5}\stackrel{\stackrel{\downarrow }{\frac{}{}}}{\leqslant}\cfrac{-50}{-5}}\implies x\leqslant 10[/tex]

The fencing needed is equal to the perimeter and will be 5x + 56.

The sum of all the sides of the rectangle will be known as the perimeter of the rectangle.

Let L be the length and W be the width of the rectangle.

Then the perimeter of the rectangle will be

Perimeter of the rectangle = Sum of all the sides

If the gardener fences in the total rectangular area shown in the illustration instead of just the square area, he will need twice as much fencing to enclose the garden.

From the diagram, the length is 28 + x. And the width is x. Then the perimeters of the rectangle will be

P = 28 + x + 28 + x + x + x + x

P = 56 + 5x

The fencing needed is equal to the perimeter and will be 5x + 56.

Step-by-step explanation:

That is a line on a graph that intersects both points x=1 and y=11, and x=1 and y=-2.

Answer:

D) linear increasing

Step-by-step explanation:

This graph is a straight line.  This means it is a linear function.

As the values of x increase, the values of y increase as well.  This means it is an increasing function.

This makes it a linear increasing function.

The first graph is the correct answer.

Answer:

The first graph which intersects (0,2)

Step-by-step explanation:

Let's get this equation into slope-intercept form, which looks like:

[tex]y=mx+b[/tex]

-x + y =2

Add x to both sides.

y = x + 2

Using information from the slope-intercept form, we can find its slope and y-intercept.

It's slope is 1, because m (which is 1 being multiplied by x) is attached to x. The y-intercept is (0,2) because when you plug in x = 0, y = 2.

From this, we can determine this equation is the first graph, because it's the only one that intersects the point (0,2).

B: (1, 8)

C: (2, 6)

D: (3, 4)    MOST EQUAL AMOUNTS

E: (4, 2)

F: (5, 0)

X: (4, 8)    OUTSIDE OF THE PRODUCTION LINE

Y: (1, 3)     UNDER THE PRODUCTION LINE

Answer:

Step-by-step explanation:

Given is a graph showing the salads produced on x axis and sandwiches produced on y axis.

The straight line ABCDEF shows the points on the straight line and Y is below the line and X is above the line.

On the line there is no point where x=y exactly.

But approximately nearer at the point where x=3 and y =4 So (3,4) is the point where most equal number are produced

2) Y is below the line meaning that resources are not utilized effectively

3) X is not possible as it is beyond the firm's capacity level shown by line ABCDEF.

Answer:

Alright well solve for y by simplifying both sides of the equation then isolating the variable

Exact form: y = - 13/2

Decimal form: y = - 6.5 Hope this helps have a nice day :)

Step-by-step explanation:

Whether using mental math to recognize the proximity of 12x49 to 12x50 or applying the distributive property, both methods yield the result 588 for the multiplication of 12 and 49.

Method 1: Using mental math:

Recognize that 12x50 = 600, a number that many people find easier to work with mentally.

Since 49 is one less than 50, 12x49 is essentially one group of 12 less than 12x50.

Therefore, simply subtract 12 from 600: 12x49 = 600 - 12 = 588.

Method 2: Using the distributive property:

Recall the distributive property: a(b + c) = ab + ac. In this case, a = 12, b = 50, and c = -1 (since 49 is 1 less than 50).

Apply the distributive property: 12(50 - 1) = 12 * 50 + 12 * (-1).

Simplify: 12x49 = 600 - 12 = 588.

Therefore, regardless of the method you choose, 12x50 serves as a stepping stone to calculating 12x49 by either providing a familiar reference point (600) or allowing you to leverage the distributive property.

Answer:

-2

Step-by-step explanation:

First, you have to find the slope.

Rise           1

-------   =   ------  = 1

Run            1            

So, the slope is 1.

Next, if you write the graph in the slope intercept from, then it will be,

y=mx+b

y=1x+-3

We already know that x is 1 So,

y=1(1)+-3

y=-2

So, the answer is -2! Hope this helps!!!

Answer:

When x = 1 ,  y = -2.

Step-by-step explanation:

I'm assuming you want the equation of this line.

The 2 points close together are (0, -3)  and (-1, -4).

Slope =  (y1-y2) / (x1 -x2)

= (-4-(-3)) / (-1 - 0)

=  -1 / -1 = 1

The  y-intercept is where y = -3.

The equation of a straight line is y = mx + c where m = the slope and c = the y-intercept, so the equation of this line is  y = 1x - 3

or y = x - 3 (the 1 may be omitted).

When x = 1, y = 1 - 3 = -2 (answer)

Sunday, she sold 6*3 pumpkins. That's 18 pumpkins.

42+18=60

Answer:

A) 16

Step-by-step explanation:

g= green apple

c= cinnamon

s= spearmint

74=g+c+s

g=2s

g-6=c

so we can replace c in the equation

74=g+g-6+s (because c=g-6)

we can also replace g in the equation

2s+2s-6+s=74 (because g=2s)

so, 5s-6=74 (add 6 to both sides)

5s=80 (divide by 5)

s=16

Answer: Hello there!

Let's define G has the number of packs of green apple, S as the number of packs of spearmint, and C as the number of packs of cinnamon.

Now we want to know the number of spearmint gum packs that Janice buys:

We know that:

G + S + C = 74

G = 2S

G - C = 6

Now we have a system of 3 equations and 3 variables, let's solve it.

In the second equation we can remove G of the equations, and replace it in the first and third equation:

G + S + C = 74

2S + S + C = 74

3S + C = 74

and

G - C = 6

2S - C = 6

Now we only have two equations, lets isolate C in the second equation

2S - C = 6

C = 2S - 6

now we can replace it in the first equation, and solve it for S

3S + C = 74

3S + 2S - 6 = 74

5S = 74 + 6 = 80

S = 80/5 = 16

She buy's 16 packs of spearmint gum.

Answer:

D. S > $400,000

Step-by-step explanation:

His salary is base salary plus commission

salary = 24000 + .08 sales

He wants a salary of at least 56000

56000<= 24000 +.08 sales

Subtract 24000

56000-24000<= 24000-24000+.08*sales

32000<= .08 * sales

Divide each side by .08

32000/.08 <= .08/.08 * sales

400000<= sales

There is an infinite number of such pairs. Even if you consider just the integers, there is still an infinite number of pairs. If you limit the number in the pairs to whole numbers, then here are the pairs:

0, 18

1, 17

2, 16

3, 15

4, 14

5, 13

6, 12

7, 11

8, 10

9, 9

The remainder when the polynomial f(x) = 3x³ - 4x² + 2x + 8 is divided by (x - 5) is constant an equal f(5).

Substitute x = 5 to the polynomial:

[tex]f(5)=3(5^3)-4(5^2)+2(5)+8=3(125)-4(25)+10+8\\\\=375-100+18=275+18=293[/tex]

Answer:

73.4

Step-by-step explanation:

When they ask for the nearest tenth you check the hundreth, it its 5 or ore than you increase the tenth

The number 74.362 would round down to 74.4

For Rounding some number to a specific value is making its value simpler mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of trimmed from the right in terms of exact digits.

We need to round  74.362 to the nearest tenth,

To round 74.362 to the nearest tenth, we need to look at the digit in the hundredth place, which is 2. Since 2 is less than 5, we round down and keep 4.

Therefore, rounding 74.362 to the nearest tenth gives us 74.4.

Answer:

x=2

Vertex (2,-8)

Intercepts: 2 ±2/3 sqrt(6)

Because the parabola opens upwards, it has a minimum at the vertex

Domain:  all real numbers

Range: y>= -8

Step-by-step explanation:

y= 3x^2 -12x+4

To find the axis of symmetry, we use the formula

h= -b/2a  where ax^2 +bx+c

h = -(-12)/2*3 = 12/6=2

The axis of symmetry is x=2

The x coordinate of the vertex is at the axis of symmetry. To find the y coordinate, substitute x into the equation

y= 3(2)^2 -12(2) +4

y = 3*4-24+4

  = 12-24+4

  = -8

The vertex is at (2,-8)

We can use the quadratic formula to find the x intercepts

x = -b ±sqrt(b^2-4ac)

    -----------------------

           2a

  =  12 ± sqrt(12^2 - 4*3*4)

  ---------------------------------

    2*3

=   12± sqrt(144-48)

 ----------------------

  6

= 12±sqrt(96)

---------------

6

=2 ±1/6 * 4sqrt(6)

= 2 ±2/3 sqrt(6)

Because the parabola opens upwards, it has a minimum at the vertex.

The domain is the values that x can take.

X can be all real numbers

The range is the values that y can take.  Since there is a minimum, y must be greater than that minimum

Range: y>= -8

Answer:

y>= -8

The expression for [tex]\(b - a\) is \(0\)[/tex].

To find the expression for [tex]\(b - a\)[/tex], we can use the given equation [tex]\(a + b = 2a\)[/tex] and solve for [tex]\(b\).[/tex]

Starting with [tex]\(a + b = 2a\)[/tex], we can subtract [tex]\(a\)[/tex] from both sides to isolate [tex]\(b\):[/tex]

[tex]\[b = 2a - a\][/tex]

[tex]\[b = a\][/tex]

Now, we can substitute [tex]\(b = a\)[/tex] into the expression [tex]\(b - a\):[/tex]

b - a = a - a

b - a = 0
