Answer:
324
Step-by-step explanation:
18 to the second power = 18 squared = 18 * 18 = 324
Answer:
a. x=0
b x=-8
c x=49/2
Step-by-step explanation:
a. x2+4=4
subtract 4 from both sides
x2=0
multiply
2x=0
divide by 2
x=0
b x2 + 16 = 0
multiply
2x+16=0
subtract both sides by 16
2x=-16
divide by 2
x=-8
c x2 − 49 = 0
multiply
2x-49=0
add 49 to both sides
2x=49
divide both sides by 2
x=49/2
Answer:
The value of x is -31.
Step-by-step explanation:
To solve this, follow the order of operations for solving equations. The step-by-step is listed below.
5(x - 4) + 2 = -173 ----> Subtract 2 from both sides
5(x - 4) = -175 ----> Divide both sides by 5
x - 4 = -35 ----> Add 4 to both sides
x = -31
Let us assume the cost of a soft drink = x dollars
Value of the gift certificate that Angela had = $5
Cost of the movie ticket = $10
Cost of a medium popcorn = $5.50
Then
27.90 + 5 = 2(10) + 2(5.50) + x
32.90 = 20 + 11 + x
32.90 = 31 + x
x = 1.90 dollars
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option or $1.90.
Answer:
Step-by-step explanation:
The leftmost line segment has a slope of -2 and (-1,-1) is a point on the line.
Equation: y = -2x-3
middle line segment has a slope of 0 and y-intercept of -2.
Equation: y = -2
The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.
y = 1.5(x-5) = 1.5x-7.5
