Answer:

(11, 0)

Step-by-step explanation:

to find the y intercept, set y to 0.

60x + 55y = 660

60x + 55 * 0 = 660

60x = 660

60x/60 = 660/60

x = 11

y intercept is (11, 0)

Answer:

8 phone cells

Step-by-step explanation:

We are told that he spent 14 minutes on the phone while routing 7 phone calls.

Now, we want to find the number of phone cells he will route for a total of 16 minutes.

Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell

Therefore, for 16 minutes, number of phone cells will be;

16 minutes ÷ 2 minutes per phone cell = 8 phone cells

Answer:650 miles hope this helps :)

Step-by-step explanation:

512+4+134=650 miles

Step-by-step explanation:

a) Polly's age = x+4 years

b) Anders and Polly's age = x+(x+4) years

c) When x=11 , put in equation 11+(11+4)=11+15=26---> T

d) T=40 x+(x+4)=40

=> 2x+4 = 40

=> 2x. = 36

=> x. = 36/2

=> x. = 18.

Answer:

B. 36a^2b^2

Step-by-step explanation:

1. Apply exponent rule: (-a)^n = a^n, if n is even

(-6ab)^2 = (6ab)^2

(6ab)^2

2. Apply exponent rule: (a × b)^n = a^nb^n

(6ab)^2 = 6^2a^2b^2

6^2a^2b^2

3. 6^2 = 36

36a^2b^2

In other words, your answer is B.

The answer is Option B)

In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions.

Given here: (-6ab)²=36a²b²

Hence, The answer is Option B)

Answer:

1/3

Step-by-step explanation:

1/3, 2/6, 3/9, 4/12.

are equivalent fractions. Equivalent fraction of a given fraction is got by multiplying or dividing its numerator and denominator by the same whole number.

The given fraction 4/12 is equivalent to 1/3 which means that both fractions represent the same value.

To find a fraction equivalent to 4/12, we need to simplify it by reducing the numerator and denominator to their lowest terms.

In this case, the GCD of 4 and 12 is 4. When we divide both the numerator and denominator by 4, we get:

4/12 = (4 ÷ 4) / (12 ÷ 4)

= 1/3

Therefore, 4/12 is equivalent to 1/3.

This means that both fractions represent the same value, but the fraction 1/3 is in its simplest form, where the numerator and denominator have no common factors other than 1.

Given:

Sides of triangles in the options.

To find:

Which could NOT be the lengths of the sides of a triangle.

Solution:

Condition for triangle:

Sum of two smaller sides of a triangle must be greater than the longest side.

In option A,

[tex]5+5=10>5[/tex]

Sides 5 in, 5 in, 5 in are the lengths of the sides of a triangle.

In option B,

[tex]10+15=25>20[/tex]

Sides 10 cm, 15 cm, 20 cm are the lengths of the sides of a triangle.

In option C,

[tex]3+4=7>5[/tex]

Sides 3 in, 4 in, 5 in are the lengths of the sides of a triangle.

In option D,

[tex]8+5=13<15[/tex]

Since, the sum of two smaller sides is less than the longest side, therefore the sides 8 ft, 15 ft, 5 ft are not the lengths of the sides of a triangle.

Therefore, the correct option is D.

Answer:

The slope of the perpendicular line  m =6

Step-by-step explanation:

Step(i):-

Given that the equation of the straight line

                                            2x + 12y =-192

                                        ⇒ 12 y = -192 -2x      

                                               [tex]y = \frac{-2x}{12}- \frac{192}{12}[/tex]

                                              [tex]y = \frac{-x}{6} - 16[/tex]

                                             y = m x +C

The slope of the given line[tex]m = \frac{-1}{6}[/tex]

Step(ii):-

The slope of the perpendicular line

                                        [tex]\frac{-1}{m}[/tex]

                                   = [tex]\frac{-1}{\frac{-1}{6} }[/tex]

The slope of the perpendicular line m =6

Answer:

The value of x is 20.

Step-by-step explanation:

Given that

Number of songs Marcus has = 10x+8

Number of songs Lara has = 15x-92

It is also given that they have the same number of songs that means both the expressions should be equal.

Putting both equal

[tex]10x+8 = 15x-92[/tex]

This is a linear equation in one variable which can be solved using properties of equality

Subtracting 10 from both sides

[tex]10x+8-10x = 15x-92-10x\\8 = 5x-92[/tex]

Adding 92 on both sides

[tex]8+92 = 5x-92+92\\100 = 5x[/tex]

Dividing both sides by 5

[tex]\frac{5x}{5} = \frac{100}{5}\\x = 20[/tex]

Hence,

The value of x is 20.

Answer: $378.33

Step-by-step explanation:

First we calculate the Simple interest which will be:

= 12000 × 4.5% × 3

= $1620

Total amount to be paid = $12000 + $1620 = $13620

Since there are 36 monthly installments, the amount of the monthly payments would be:

= $13620 / 36

= $378.33
