Answer:
Step-by-step explanation:
y= 3.50m + 35
y= 4.25m
4.25m = 3.50m + 35
.75m = 35
m = about 47 movies

Divide the estimated number by the exact number and multiple by 100
Answer:
(28000,40000) or $28,000 to $40,000
Step-by-step explanation:
plug in values as V and solve for x:
12,000=22,000-0.25x
-10,000=-0.25x
40,000=x
15,000=22,000-0.25x
-7,000=-0.25x
28,000=x
an interval notation always has the lower value first so its:
(28000,40000) or $28,000 to $40,000
Answer:
Step-by-step explanation:
Step1: isolate the square root on the left hand side.
Original equation :x+1=√-6x-6
Isolate :x+1=√-6x-6.
Step2: raise both sides to the second power.
(x+1)^2=(√-6x-6)^2
(x+1)(x+1)=-6x-6
Step3: after squaring, solve the quadratic equation.
x^2+2x-1=-6x-6
x^2+8x+7=0
x^2+7x+x+7=0
x(x+7)+1(x+7)=0
(x+1)(x+7)=0
x=-1,-7
Step4:check that the first solution correct.
Input x=-1 into the original equation
x+1=√-6x-6
-1+1=√+6-6
0=0
Step5:check that the second equation is correct.
Input x=-7 into the original equation
x+1=√-6x-6
-7+1=√42-6
-6=√36
-6#6
Therefore one solution is found.
x=-1
