Answer:
2x²-32 ⇒ x²=16⇒ (-4,4)
4x²-100 ⇒x²=25 ⇒(-5,5)
x²-55=9 ⇒x²=64 ⇒(-8,8)
x²-140=-19 ⇒x²=121 ⇒(-11,11)
2x²-18=0 ⇒x²=9 ⇒(-3,3)
Answer:
11
Step-by-step explanation:
slope is change in y over change in x. so, if x is increasing by one every time and y is increasing by 11, then the slope is 11/1, which we write as 11.
Answer: Car B traveled 60 mph.
Step-by-step explanation:
A= B-15
A: (B - 15)(2 hr)=D
B: (B)(1.5)=D
Since B and A traveled the same distance you can plug in 1.5B for D.
2B - 30 = 1.5B
-1.5B +30 = -1.5B
——————+30—
2(0.5B) = 2(30)
B = 60 mph
Answer:
x=5
Step-by-step explanation:
so to isolate the x you dived the -3 to both sides
so it will now be
x=5 because a negative times or divided by a negative equals a positive so to prove that x=5
-3(5)=-15
which is true
Answer:
16^3
Step-by-step explanation:
16 x 16 x 16 is the same thing as 16 to the 3rd power. The power is how many times you multiply the number by itself.
