Me and my mom are confused. Please help!!​

Answer:

7) 3x=45( corresponding angles formed on parallel lines)

x=45/3

x=15

8)120=2x+10(corresponding angles formed on parallel lines)

or,120-10=2x

or,110/2=x

or,x=55

Answer:

say you buy something for 10 dollars, you are going to get charged for it, but if you take item off of your shopping cart you are taking away the -10 dollars that wouldve been charged.

Step-by-step explanation:

the reason this works is because you take away something that makes it less.

- (-7) is basically just saying delete that -7. that's why - (-7) is the same as +7

Answer:

f(-5) = 4(-5) + 1 = -20 + 1 = -19

f(-1) = 4(-1) + 1 = -4 + 1 = -3

f(2) = 4(2) + 1 = 8 + 1 = 9

f(3) = 4(3) + 1 = 12 + 1 = 13

f(5) = 4(5) + 1 = 20 + 1 = 21

Answer:

[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 \\ [/tex]

Step-by-step explanation:

[tex]\tt{} \sqrt{ {x}^{2} - 16 } - 3 \sqrt{x - 4} = 0[/tex]

[tex]\tt{} \sqrt{ {x}^{2} - 16 } = 3 \sqrt{x - 4} [/tex]

[tex]\tt{}{x}^{2} - 16 = 9(x - 4)[/tex]

[tex]\tt{}(x - 4).(x + 4) = 9(x - 4)[/tex]

[tex]\tt{}(x - 4) \times (x + 4 - 9) = 0[/tex]

[tex]\tt{}( x - 4) \times (x - 5) = 0[/tex]

[tex]\tt{}x - 4 = 0 \\ \tt{}x - 5 = 0[/tex]

[tex]\tt{}x = 4 \\ \tt{}x = 5 \\ \\ [/tex]

[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 [/tex]

Answer:

x = 4, 5.

Step-by-step explanation:

√(x^2 - 16) - 3√(x - 4) = 0

√(x^2 - 16) = 3√(x - 4)

Square both sides of the equation:

x^2 - 16 = 9(x - 4)

x^2 - 9x - 16 + 36 = 0

x^2 - 9x + 20 = 0

(x - 4)(x - 5) = 0

x = 4, 5.

As the original equation contained square roots:

We test for extraneous solutions:

x = 4:

√(4^2 - 16) - 3√(4 - 4) = 0 - 3*0 = 0  so x = 4 is OK.

x = 5:

√(5^2 - 16) - 3√(5 - 4) = √9 - 3√1 = 0  so x = 5 is also OK.

Answer:

8 tickets

Step-by-step explanation:

x = 10 in the given equation.

We have then:

C (x) = 17.5x - 10

C (10) = 17.5 * (10) - 10

C (10) = 165

Answer:

to buy 10 tickets cost:

$ 165

b. How many tickets can you buy with $ 130?  

For this case we must make the substitution: C (x) = 130

We have then:

C (x) = 17.5x - 10

130 = 17.5x - 10

Clearing x we have:

17.5x = 130 + 10

17.5x = 140

x = (140) / (17.5)

x = 8

Answer:

You can buy 8 tickets with $ 130
