The answer to this is step 2 because they multiplied when they should of subtracted the 10 and the 12.

Explanation:
The point-slope formula states:
(

y

=

(
x

x

)
Where
m
is the slope and
(
x

y

)
is a point the line passes through.
Substituting the slope and values from the point in the problem gives:
(
y

(

(

Just to be different we'll start with intercept intercept form which says the line through x intercept (a,0) and y intercept (0,b) is
Through (4,0) and (0,-2) that's
Multiply through by the common denominator of 4 for standard form:
x - 2y = 4
For slope intercept form we solve for y
-2 y = -x + 4
y = (1/2) x - 2
We see our slope is (1/2) and we go through (4,0) so point slope form is
y - 0 = (1/2)(x - 4)
y = (1/2)(x-4)
The answer is 65880000 and here are the steps
Answer:
The angle measures are 53.5° and 36.5°.
Step-by-step explanation:
We can create a systems of equations, assuming x and y are the angle measures.
Since the two angles are complementary, their angle measures will add up to 90.
x + y = 90
x - y = 17
We can now use the process of elimination, and end up with:
2x = 107
Dividing both sides by two gets us
x = 53.5
Substituting this value into an equation will get us y
53.5 + y = 90
y = 36.5
Hope this helped!
