One can solve this by first using order of operations, and then combining like terms.
First is parenthesis
9x + 2x(9) - 2(9x)
Now we do the multiplication
9x + 18x - 18x
Now we combine like terms
9x
Slope-intercept form: y = mx + b
m = the slope
b = y-intercept.
In this problem,
m = 3/5
b = ?
So far y = 3/5x + b
Let's plug the point (-3, -1) into our slope equation.
-1 = 3/5(-3) + b
Simplify the right side.
-1 = -9/5 + b
Add 9/5 to both sides.
4/5 = b
The equation is: y = 3/5x + 4/5
Answer choice A is correct.
Answer:
x = -5
Step-by-step explanation:
Answer:
x = 76°
z = 14°
y = 42°
Step-by-step explanation:
48 + 2x = 180° because these three makes a straight line
2x = 180 - 48
2x = 132
x = 76°
x + z = 90° because these two angles are complementary angles since we know the value of x
76 + z = 90°
z = 90 - 76
z = 14°
48° + y = 90° because these two angles are complementary angles
y = 90 - 48
y = 42°
