The length of the wall will be 25 feet less than how long it was on day one.

You have to multiply both numbers. Since he can tear down 5 feet in one day, you would express that as 5x1. In 5 days, you would do 5x5 which gives you 25 feet. Hope this helped!

Answer:

theres two answers to this question and im not sure which one is correct

it can be -8 or 90

you should specify which one is t1 and which one is t2

Step-by-step explanation:

$2( {2})^{2} + 8( - 5) + 24 = - 8$

$2( { - 5})^{2} + 8(2) + 24 = 90$

correct me if im wrong

How can you determine the coordinates of any image that is dilated with the center of dilation at the origin without graphing

arlik [135]

Answer:

$(x,y)\rightarrow (kx,ky)$

Step-by-step explanation:

A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.

The dilation with the center of dilation at the origin and a scale factor of k has the rule

$(x,y)\rightarrow (kx,ky)$

This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).

What is an equation of the line that passes through the points 0,-2and 0,-5

kherson [118]

Answer:

Any equation with a slope of 3 will work. You can use any y-intercept. This equation will work: y = 3x+1

Step-by-step-explanation:

3x says that the slope is 3, and on a coordinate plane, 2 is 3 places above 5, and since the slope is 3, it will go 3 spots up, and run into (0,2)
