Answer:
see explanation
Step-by-step explanation:
from the diagram
DF = DE + EF , that is
4x + 2 = x + 7 + 7
4x + 2 = x + 14 ( subtract x from both sides )
3x + 2 = 14 ( subtract 2 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Then
DE = x + 7 = 4 + 7 = 11
DF = 4x + 2 = 4(4) + 2 = 16 + 2 = 18
It would be answer choice A or 5

Answer:
The answer would be:
y = 2x - 3
Step-by-step explanation:
Slope Inercept - Form:
y = mx + b
[m] being the slope
[b] being the y - intercept
To find the slope, there are mainly two ways, either see howmany squares it goes up by, or choose two points and find the slope with slope formula.
Either way, the slope is still: 2
[m] = 2
Then find the y - intercept.
Y - intercept is basically the point in which crosses on the y - axis, and the point that crosses it is: -3
[b] = -3
Thats how you find y - intercept.
Now, put it into slope intercept form.
y = mx + b
y = 2x - 3
Hope this helps!
Divide both sides of this eq'n by -9. You'll get y = -1.
