Answer:
To find the solutions to the system of equations we need to graph the following equations:
y = 8 - 4x (Red line)
y = 2x - 4 (Blue line)
The point of interception, is the solution to the system of equations.
By looking at the graph attached, you can see that the point of itersection is at (2,0)
-4(7a+5)= —160
distribute the -4 on the left hand side
-4* 7a + -4*5 = -160
-28a +-20 = 160
-28a -20 = -160
add 20 to each side
-28a-20+20 = -160 +20
-28a = -140
divide by -28 on each side
-28a/-28 = -140/-28
a = 5
Answer: a=5

5. B
Two consecutive odd integers with a sum of 36 are 17 and 19.
To find these integers, we start by using the definition of consecutive odd integers to represent our consecutive odd integers as n and n + 2. Now, we can set up an equation using the fact that the sum of these two integers is equal to 36.
n + (n + 2) = 36
Solving this equation for n will give us the first of our consecutive odd integers that sum to 36.
n + (n + 2) = 36
Simplify the left-hand side.
2n + 2 = 36
Subtract 2 from both sides of the equation.
2n = 34
Divide both sides of the equation by 2.
n = 17
We get that the first of the two consecutive odd integers is 17, so the second one is 17 + 2, or 19. Therefore, we find that two consecutive odd integers whose sum is 36 are 17 and 19.h
