Step-by-step explanation:
always draw triangle b first. for triangle b it is reflected across the x-axis which means all y valies become negative. then for triangle c, you swap the x and y values around.
Answer:
r = 2.75
Step-by-step explanation:
1.25 + r = 4
Subtract 1.25 on both sides.
1.25 + r - 1.25 = 4 - 1.25
r = 4 - 1.25
r = 2.75
The solution to the equation is r = 2.75.
Answer:
x should be -3
Step-by-step explanation:
f(x) = 5/3x + 10
f(-3) = (5*-3)/3 + 10
f(-3) = -15/3 + 10
f(-3) = -5 + 10
f(-3) = 5
g(x) = -2x - 1
g(-3) = -2(-3) - 1
Negatives cancel out
g(-3) = 2(3) - 1
g(-3) = 6 - 1
g(-3) = 5
5 is equal to 5, so x should be -3 in this case.
