Solve the inequality 2x+10<-28

Otrada [13]

Answer:

x < -19

Step-by-step explanation:

2x+10<-28

Subtract 10 from each side

2x+10-10<-28-10

2x< -38

Divide each side by 2

2x/2 <-38/2

x < -19

What is the equation of the line that passes through the points (15, 9) and (Negative 2, 9)? y =

Alja [10]

Answer:

Y=9

Step-by-step explanation:

Because it passes through two points in a straight line, it must have no coefficient for x, just a Y-Intercept equal to the Y of the two points.

Graph the image of the figure after a dilation with a scale factor of 1/3 centered at (1, −2) . Use the polygon tool to graph th

brilliants [131]

Answer:

New image will have (2,1) , (-2,0) and (-2,-2) as new vertex.

Below is the graph.

Step-by-step explanation:

Given the triangle with points (4,7) , (-8,4) and (-8,-2) having dilation center at (1,-2) .

We have to dilate using a factor of 1/3 and graph the new image.

Let us find all the three points,

Formula,

New point = [old point - dilation center]* scale factor + dilation center

So,

For (4,7)

$[(4,7)- (1,-2)]*\frac{1}{3} + (1,-2)$

$[3,9]*\frac{1}{3} +(1,-2)$

$[1,3]+(1,-2)= (2,1)$

For (-8,4)

$[(-8,4)- (1,-2)]*\frac{1}{3} + (1,-2)$

$[-9,6]*\frac{1}{3} +(1,-2)$

$[-3,2]+(1,-2)= (-2,0)$

For (-8,-2)

$[(-8,-2)- (1,-2)]*\frac{1}{3} + (1,-2)$

$[-9,0]*\frac{1}{3} +(1,-2)$

$[-3,0]+(1,-2)= (-2,-2)$

Therefore these (2,1) , (-2,0) and (-2,-2) are the new vertices after dilation.
