Find the solution of y = 4x + 2 for x = -5.


A.
(-5, -18)


B.
(-5, 22)


C.
(-18, -5)

Answers

Answer 1

Answer: THE ANSWER WOULD BE A. (-5, -18)

Notice how y=4x%2B2 is in slope-intercept form y=mx%2Bb where m is the slope and b is the y-intercept.

So this shows us that the slope is m=4 and the y-intercept is b=2 which is the point (0,2)

You can always plot an equation like this to find intercepts

and slope. Each point requires an x and a y. My

way is to make x+=+0 and find y,

then I make y+=+0 and find x

y+=+4x+%2B+2

y+=+4%2A0+%2B+2 solve for y

y+=+2

the point is (0,2)

then,

0+=+4x+%2B+2 solve for x

subtract 2 from both sides

4x+=+-2

x+=+-%281%2F2%29

the point is (-%281%2F2%29,0)  

Once you have any two points, you can draw the line by connecting them

When the equation is in the form

y+=+mx+%2B+b

m = slope

b = y-intercept

So, your equation y+=+4x+%2B+2

m+=+4 (slope)

b+=+2 (y-intercept)

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

P varies inversely with x. If P = 12 when x = 4, find the value of P when x = −48.

Answers

Answer:

P = - 1

Step-by-step explanation:

Given P varies inversely with x the the equation relating them is

P = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition P = 12 when x = 4

12 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

48 = k

P = [tex]\frac{48}{x}[/tex] ← equation of variation

When x = - 48, then

P = [tex]\frac{48}{-48}[/tex] = - 1

The function y=-16x^2+16x+32 represents the height in feet of a firework x seconds after it is launched

Answers

Answer:

36feet

Step-by-step explanation:

Since we are not asked what to find, we can as well find the maximum height reached by the rocket

At max height, velocity is zero

V = dy/dx = 0

dy/dx = -32x + 16

0 = -32x+16

32x = 16

x = 16/32

x = 0.5s

Get the maximum height

y = -16(0.5)^2+16(0.5) + 32

y = -4+8+32

y = 36feet

Hence the max height reached by the rocket is 36feet

Answers

Answer:

Ratio 5 = 9375

Ratio 3 = 5625

Step-by-step explanation:

Write your question here (Keep it simple and clear to get the best answer)

a sum of 1,5000.00 in the ratio 5:3

The ratio is given as:

5:3

Total Proportion = 5+3 = 8

For ratio 5

= 5/8 × 15000

= 9375

For ratio 3

= 3/8 × 15000

= 5625

Answers

Answer:

7 m

Step-by-step explanation:

We are told that;

100 cm = 1 m

Thus; 2.54 cm = 2.54 × 1/100 = 0.0254 m

This means that;

1 inch = 0.0254 m

Thus; 275 inches will give; 275 × 0.0254/1 = 6.985 m

Approximating to the nearest metre gives 7 m

PART A:

To find the rate of change, put change in y over change in x. In order to first find the changes, you must subtract two y values from each other and two x values from each other, like this:

Change in y = 20-10

Change in x = 4-2

Then you can put these over each other:

20-10/4-2

Then simplify

20-10/4-2 = 10/2 = 5/1 = 5

So, this means the rate of change is 5. $5 per bushel.

If you also need part B it would be helpful to see the other chart because it's hard to understand in the writing you included. :) Comment and let me know if you post it so I can help you out!

Part A: 7 dollars  

- The graph shows that 2 bushels is 14 dollars,  because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.

- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.

- 7 can be known as the slope and  rate of change.

Part B:2 dollars

- The years before show 2 bushes was 10 dollars

-so you would divide 10 by two you would get five  To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.

-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

white chocolate costs $2.00 per bar, and dark chocolate costs $2.50 per bar. If you buy 15 bars of chocolate for $34, how many of each bar did you buy?

Answers

Answer:

7 white and 8 dark bars

Step-by-step explanation:

x white bars

15-x dark bars

cost of white bars is 2 * x

cost of dark bars is 2,5 * (15-x)

Write an equation

2x + 2,5 * (15-x) = 34

2x + 37,5 - 2,5x = 34

-0,5 x = - 3,5

x = 7

So we have x = 7 white bars

and 15 - x = 15 - 7 = 8 dark bars

Ada is making rice. The instructions call for 2 1/4 cups of water for 1 cup of rice. Ada is using only 1/3 cup of rice.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The number of cups of rice = 1 cup

The number of cups of water for making rice = 2 1/4 cups of water

So the equation for

The number of cups of water for 1/3 cups of rice =
Number of cups of water for making rice / 3

The number of cups of water for 1/3 cups of rice = 2 ( 1/4 ) / 3

                                                                                 = 9/4 / 3

                                                                                 = 3 / 4 cups of water

Therefore , the number is 3/4 cups of water

Hence , The required number of cups of water is 3/4 cups of water

But the number of chocolate covered cherries =84

Total ratio is given as 5+2 = 7
