Answer:

y = -2x + 12

Step-by-step explanation:

Step 1: find the slope

y = 1/2x + 5

The equation of the line is

y = mx + c

m - slope

m = 1/2

Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other

m = -2

Step 2 : using a point slope form

y - y1 = m( x - x1)

( 2 , 5)

x1 = 2

y1 = 5

y - 2 = -2( x - 5)

y - 2 = -2x + 10

y = -2x + 10 + 2

y = -2x + 12

The equation of the line is

y = -2x + 12

Answer:[tex]P=\frac{2}{5}[/tex]

Step-by-step explanation:

Given

A movie theater has 7 seats in the front row  

12 seats in the middle row

11 seats in the back row

Probability first person who enters the theater will be in the middle row

[tex]P=\frac{\text{No. of middle seats}}{\text{total seats}}[/tex]

[tex]P=\frac{12}{7+12+11}=\frac{12}{30}[/tex]

[tex]P=\frac{2}{5}[/tex]

Answer:

c² = 34

Explanation:

Pythagorean Theorem: a² + b² = c²

3² + 5² = c²

3² = 9

5² = 25

9 + 25 = 34

34 = c²

$75

Step-by-step explanation:

Cost = $500

Sam has to pay a 15% tax

To compute his tax, we use the step outlined bellow

tax= 15/100*500

tax= 0.15*500

tax=$75

Hence his tax is $75

Answer:

D. x>-3

Step-by-step explanation:

Since the dot on -3 is not shaded in we know it is not ≤ or ≥ so option A and C are eliminated.

Remember if the arrow is pointing to the left (<-----) Then it is Less-than which is <.

If the arrow is pointing to the right (----->) Then it is Greater-than which is >.

Since the arrow is pointing right the answer will be x>-3 which is D

Answer:

87 degrees

Step-by-step explanation:

the three angles of a triangle add up to one hundred eighty degrees.

1. Add the degrees of the known angles together

56 + 37 = 93

2. Since a triangle adds up to one hundred eighty degrees, you would subtract your known degrees from the total

180 - 93 = 87

Answer:

1190

Step-by-step explanation:

We have the ratio: 8:340 which means that 340 copies are printed in 8 minutes

We want to find out how many color copies are printed in 1 minute so we divide by 8

so our new ratio is now 1:42.5

We now multiply this ratio by 28 to find out how many are printed in 28 minutes

28:1190

our answer is 1190 copies

Step-by-step explanation:

Part A; 15(67)

= $1005

Part B; ??

The number of tickets to be sold if, The cost of the banquet hall is $500, The cost per ticket is $15, the Total money to be raised is $1000, is 67, and the equation is given by 1000 = 15x.

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

In other terms, it is a mathematical statement stating that "this is equivalent to that."

Given:

The cost of the banquet hall = $500,

The cost per ticket = $15,

Total money to be raised = $1000

Write the equation of the number of tickets as shown below,

1000 = 15x

Here, x is the number of tickets,

x = 1000 / 15

x = 66.67 or 67

Answer:

The average rate of change is -75

Step-by-step explanation:

The Average Rate of Change (ARC)

It's a measure of how much the function changed per unit, over a given interval.

Given a function F(x) and an interval between x=a and x=b, the average rate of change is:

[tex]\displaystyle A=\frac{F(b)-F(a)}{b-a}[/tex]

The function is:

[tex]F(x)=-x^3+24x^2-179x+495[/tex]

and it's required to find the ARC between x=2 and x=5.

Calculate F(2) and F(5):

[tex]F(2)=-2^3+24*2^2-179*2+495=225[/tex]

[tex]F(5)=-5^3+24*5^2-179*5+495=75[/tex]

The ARC is:

[tex]\displaystyle A=\frac{75-225}{5-3}=\frac{-150}{2}=-75[/tex]

The average rate of change is -75

B: B works! Both 3 and 7 are factors of 21.

C: C doesn't work. 7 is not a factor of 3.

D: D doesn't work. Neither are a factor of 4.

Answer:

$90.98

Step-by-step explanation:

Answer:

y=1, x=2

Step-by-step explanation:

so first solve for y. plus x=3y-1 into the other equation.  

so 3(3y-1)+4y=10.  

Simplify

9y-3+4y=10           Add 3 to both sides

9y+4y=13               Add

13y=13 .                  Divide 13 from both sides

y=1

Plug 1 into the first equation.  

x=3(1)-1

x=3-1

x=2 and y=1
