4(a + 2) + 9 = 5
to solve this problem lets solve this step by step
Step 1 - lets solve this part of problem 4(a + 2 )
by using distributive property we get,
4a + 8 + 9 = 5
Step 2 - adding the like terms
4a + 17 = 5
Step 3 - subtracting 17 from both sides
4a + 17 - 17 = 5 - 17
4a = -12
Step 4 - dividing both sides by 4
a = -3
So our final answer is a = -3
Hope this helps you :)
Answer:
(1,4)
Step-by-step explanation:
Use substitution
-5x=-(x+3)-1
x=1
-5(1)=-y-1
y=4
Yes. You did it right. Most of the angles are corresponding, and once you found the measure of x, you could use the corresponding angles postulate.
Answer:
Complementary angles form a right angle (L shape) and have a sum of 90 degrees. Supplementary angles form a straight line and have a sum of 180 degrees.
the equation describes a horizontal line with a y-intercept of -4. as the line is horizontal, the slope is 0.
