x=number of members
y=number of non-members
total peple was 239 so x+y=239
total collected was 593 so 2x+3y=593
we have 2 equations, 2 unknowns
x+y=239
2x+3y=593
elimination
multiply 1st equation by -2
-2x-2y=-478
add to 2nd equation
-2x-2y=-478
<u>2x+3y=593 +</u>
0x+1y=115
y=115
solve for x
x+y=239
x+115=239
x=124
124 zoo members and 115 non-members visited the zoo that day
Answer:
d= 4
Step-by-step explanation:
The DISTANCE between the two points can be found by the distance formula
d^2 = (x1-x2)^2 + (y1-y2)^2
( 1-5)^2 + (2-2)^2
= 16
d = 4
You can just LOOK and realize the two points have the same y values...so the distance is just the distance between the x coordinates 5 -1 = 4
Answer:
-65/81
Step-by-step explanation:
Answer:
9x² + 28x - 32
Step-by-step explanation:
Given
(9x - 8)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
9x(x + 4) - 8(x + 4) ← distribute both parenthesis
= 9x² + 36x - 8x - 32 ← collect like terms
= 9x² + 28x - 32
