Answer:
65.42 is your answer
Step-by-step explanation:
The answer is c ) 15 cm
a = (h×b)/2
a= (15×20)/2
a= 300/2
a= 150 cm²
Answer:7x+6y^2
Step-by-step explanation:
A: You have 2 equations for y. They will intersect at some point where "y" is the same for both equations. That is why in equation y=2x+2 you exchange "y" with other equation you got which is y=4x. once you do that you will have
4x=2x+2.
B: 4x = 2x + 2
x = -3 -12 = -4 false
x = -2 -8 = -2 false
x = -1 -4 = 0 false
x = 0 0 = 2 false
x = 1 4 = 4 true
x = 2 8 = 6 false
x = 3 12 = 8 false
C. To solve that equation graphically first you draw function y=4x than you draw function y = 2x + 2. After you do that there will be 1 point on graph where functions will intersect. On graph you simply read x value of point where they intersect and that is your solution.
Answer:
y + (y-8) < 41
lee <24 in whole numbers
Step-by-step explanation:
lee =y
toby = lee -8
= y-8
sum of their ages < 41
lee + toby < 41
y + (y-8) < 41
combine like terms
2y-8 <41
add 8 to each side
2y < 49
divide by 2
y < 49/2
y < 24.5
y <24 in whole numbers
