Answer:

-4

Step-by-step explanation:

We know it's a linear equation and the slope is a whole number. Using point slope form we will write the equation:

y - y1 = m (x - x1) in which y1 is -7, m is 3, and x1 is -1

y - (-7) = 3(x-(-1))

y+7 = 3(x+1)

y+7 = 3x +3

Change to slope-intercept form:

y = 3x + 3 - 7

y = 3x = -4

the y intercept is -4

You play video games online. When you sign up with the game site, you get 400 points. You earn 50 more points for each hour that

aleksley [76]

The answer is 12 but the way you get it is you subtract 400 from 1000 which gives you 600 then you divide 600 by 50 to get 12. So it looks like this 1000-400= 600, 600/50=12. Hope this helps. :)

Answer:

Step-by-step explanation:

Make a system of equations.

Justin = j

Greg = g

j + 15 = g

g/2 + 75 = j

We can substitute.

(j + 15)/2 + 75 = j

j/2 + 15/2 + 75 = j

j/2 = 165/2

j = 165

Substitute back into j + 15 = g

165 + 15 = g

g = 180

Please help i will brainly Δdef and Δxyz are similar isosceles triangles.

aivan3 [116]

Answer:

Part 1) The ratio of the sides is 1.5

Part 2) see the explanation

Step-by-step explanation:

Part 1) we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

If Δdef and Δxyz are similar (given problem)

then

$\frac{XY}{DE}=\frac{ZY}{FE}$

substitute the values

$\frac{15}{10}=\frac{ZY}{6}$

solve for FY

$ZY=15(6)/10=9\ cm$

When two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

The scale factor is equal to

$\frac{15}{10}=\frac{9}{6}=1.5$

Part 2) How you could verify that these two triangles are indeed similar.

Remember that

In similar figures the corresponding angles are congruent

m∠D≅m∠X

m∠W≅m∠Y

m∠F≅m∠Z

then

Triangles are similar
