Which of these equations is correct when x = -2?
A
x + 8 = 5
B
3x - 1 = -10
C
2x - 7 = -11
D
-95x = -190

Answer:

a-5, b-4, c-1, d-3, e-2

Step-by-step explanation:

1) 3x+4 = 7x-8

-4x = -12

x = -3 (c)

2) 2x = 7x-5

-5x = 5

x = 1 (e)

3) 5x-8 = 5x+12

0x = 20

no solution (d)

4) 8x+4 = -2x-16

10x = -20

x = -2 (b)

5) -3x+5 = -3x+5

all real numbers (a)

Answer:

131

Step-by-step explanation:

if the number to the right of the decimal is lower than 5 it stays the same , but if it is higher then 5 it gets raised to the next number after that .

Answer:

f(x) = 5x - 5

Step-by-step explanation:

Let the equation of the linear function is,

f(x) = mx + b

Here, m = Slope of the graph

b = y-intercept

Slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]

From the table attached,

Slope of the line passing through (2, 5) and (6, 25) will be,

m = [tex]\frac{25-5}{6-2}[/tex]

m = 5

Equation of the linear function will be,

f(x) = 5x + b

Since, a point (10, 45) lies on the function,

45 = 5(10) + b

b = 45 - 50

b = -5

Equation of the linear function will be,

f(x) = 5x - 5

Answer:

Step-by-step explanation:

This table reflects the proportional relationship amongst number of teaspoons, number of tablespoon, number of cups.

In other words these three measures are proportional.

By taking proportionality ratio of 'number of tablespoons' and 'number of cups' first.

[tex]\frac{12}{48}=\frac{C}{3}[/tex]

C = [tex]\frac{12\times 3}{48}[/tex]

C = 0.75

Similarly, [tex]\frac{y}{2}=\frac{12}{C}[/tex]

[tex]\frac{y}{12}=\frac{2}{0.75}[/tex]

y = [tex]\frac{24}{0.75}[/tex]

y = 32

Now, [tex]\frac{t}{36}=\frac{y}{12}[/tex]

[tex]\frac{t}{36}=\frac{32}{12}[/tex]

t = 96

By the same rule,

[tex]\frac{36}{x}= \frac{12}{48}[/tex]

x = [tex]\frac{48\times 36}{12}[/tex]

x = 144

Therefore, complete table will be,

Number of teaspoons       Number of tablespoons          Number of cups

          96                                            32                                          2

          36                                            12                                        0.75

         144                                            48                                          3

Talk-It-Up is the best value

Step-by-step explanation:

TIU=$95/month

TIC=$35/month + $10/gigabyte

Data usage=8 gigabytes

TIC=$35+$10(8)=$35+$80=$115

TIU is cheaper

Frankie is comparing the monthly costs of two cellphone plans:

-Talk-It-Up is Cheaper

Let us assume:

TIU = Talk-It-Up.

TIC = Talk-is-Cheap

Given:

TIU=$95/month

TIC=$35/month + $10/gigabyte

Data usage=8 gigabytes

Since, 95 [tex]\ge[/tex]115.

TIU is cheaper.

Answer:

5/6

Step-by-step explanation:

When adding fractions, you must ensure the denominator is the same in both fractions.

In this case, the 3 can be multiplied by 2 to equal 6, the other denominator.

When multiplying fractions to create a common denominator, you must multiply the both the numerator and the denominator by the same value, to ensure that the fraction is still equivalent.

2/3 × 2/2 = (2×2)/(3×2) = 4/6

Replace 2/3 with its equivalent 4/6.

Now you will add the numerators together.

1/6 + 4/6 = (1+4)/6 = 5/6

Your final answer is 5/6

Answer:

EASY PEASY

n = -18

Step-by-step explanation:

Simplifying

n + 7 = -11

Reorder the term:

7 + n = -11

Solving

7 + n = -11

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + n = -11 + -7

Combine like terms: 7 + -7 = 0

0 + n = -11 + -7

n = -11 + -7

Combine like terms: -11 + -7 = -18

n = -18

Simplifying

n = -18
