Answer:

96miles - 12 cm

Step-by-step explanation:

3*4 = 12, 24*4 = 96

Answer:

no solutions

Step-by-step explanation:

plug in y to x:

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20 ( you would subtract 15x from 15x.)

0 + 40 = 20

40 = 20

40 does not equal 20 so it would be no solutions.

Using substitution, the system above has no solutions.

Given  that,

Based on the above information, the calculation is as follows:

  Here we put the y value

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20  

0 + 40 = 20

40 = 20

Since 40 does not equal 20 so it would be no solutions.

Answer:q=-6

Step-by-step explanation:

If the solution of the system is  {(x,y) : x-3y=4}, then both equation should have proportional coefficients:

[tex]1/2=-3/q=4/8[/tex]

Solve it:

1/2 = -3/q

q=-3*2

q=-6

Check whether q=-6 is correct answer, substituting this value into the first ratio:

[tex]1/2=-3/-6=4/8[/tex]

q=-6

Answer:

Step-by-step explanation:

If the solution to the system is the first equation only, then both equations should be same:

Double the first equation, then both of coefficients of y and constant will be equal:

Comparing we get Q = 2

Answer:

the equation would be (3∙18.50)+2x=104.50

Step-by-step explanation:

So you would do BEDMAS. First answer what in the brackets (3 ∙ 18.50=55.50)Then you subtract 55.50 on both sides

2x=104.50. then you just divide two by each side and the x will equal 24.50 So they parents tickets were 24.50.

Answer:$5.99

Step-by-step explanation:

Answer:

1) -1

2) -1/4, 4

Step-by-step explanation:

1)

The first equation is

y = -x + 5

Comparing with

y = mx + b, we see thqat the slope, m, is -1

1) Answer: slope = -1

2)

The equations are

y = -1/4 x + 2 and

y = 4x + 8

Comparing the two equations with y = mx + b, we see that the slopes are

-1/4 and 4

2) Answer: slope = -1/4; slope = 4

Answer:

For the first one, we see that from one point to another it rises one and goes to the left one. This means the slope is 1/-1, which is -1.

For the second one, the slope of the first equation is -1/4, and the slope of the second equation is 4/1, or 4. Since the lines are perpendicular in 2, the two lines will be opposite reciprocals of each other.

Answer:

First blank= -1

Second blank= 14

Step-by-step explanation:

Plug in x to the equation. 1/7 x (-7)= -7/7=-1

2=1/7(x) to divide fractions you multiply by the reciprocal

2 x 7/1= 1/7× 7/1

14/1=14

Answer: -11

Step-by-step explanation:

+(-8) can be simplified to -8 because when you multiply a positive sign by a negative sign, the outcome is a negative sign. So your problem is -3-8= and the answer is -11 because when two numbers with the same sign are subtracted/added by each other, the numbers just get added and the sign stays the same. If you're still confused, use a number line. Hope this helps!

Answer:

(2, - 1 )

Step-by-step explanation:

Given the 2 equations

y = 4x - 9 → (1)

y = x - 3 → (2)

Substitute y = 4x - 9 into (2)

4x - 9 = x - 3 ( subtract x from both sides )

3x - 9 = - 3 ( add 9 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into either of the 2 equations for y

Substituting into (2)

y = 2 - 3 = - 1

solution is (2, - 1 )

Answer:

Option B : 1/2 is the correct answer.

Step-by-step explanation:

Given ordered pairs are;

(3, 6) and (5, 7).

We have to find the rate of change which is also known as slope.

Slope is the steepness of a line.

The formula of slope is given by;

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

m = [tex]\frac{7-6}{5-3}[/tex]

m = [tex]\frac{1}{2}[/tex]

Hence,

Option B : 1/2 is the correct answer.

Borrowers choosing an adjustable-rate mortgage often pay a lower interest rate during the first few years.

Option C is the correct answer.

We have,

When borrowers choose an adjustable-rate mortgage (ARM), they typically enjoy an initial period with a lower interest rate compared to a fixed-rate mortgage.

This initial period is often referred to as the "teaser rate" or "introductory rate." However, after this initial period, the interest rate on the ARM can fluctuate periodically based on changes in a specified financial index, which can result in higher or lower interest rates in subsequent years.

Borrowers who choose an ARM are exposed to the risk of interest rate fluctuations, which can lead to higher monthly payments in the future if interest rates rise.

Thus,

Borrowers choosing an adjustable-rate mortgage often pay a lower interest rate during the first few years.

Problem 1

----------------

Work Shown:

The two points are [tex](x_1,y_1) = (1,-2)[/tex]  and [tex](x_2,y_2) = (4,4)[/tex]

Apply the distance formula to get the following

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-4)^2 + (-2-4)^2}\\\\d = \sqrt{(-3)^2 + (-6)^2}\\\\d = \sqrt{9 + 36}\\\\d = \sqrt{45}\\\\d \approx 6.7082039\\\\d \approx 6.7\\\\[/tex]

The distance between the two endpoints is roughly 6.7 units. This is the same as saying the segment is roughly 6.7 units long.

======================================================

Problem 2

----------------

Work Shown:

We'll use the distance formula here as well.

This time we have the two points [tex](x_1,y_1) = (3,1)[/tex] and [tex](x_2,y_2) = (5,-2)[/tex]

The distance between them is...

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-5)^2 + (1-(-2))^2}\\\\d = \sqrt{(3-5)^2 + (1+2)^2}\\\\d = \sqrt{(-2)^2 + (3)^2}\\\\d = \sqrt{4 + 9}\\\\d = \sqrt{13}\\\\d \approx 3.6055513\\\\d \approx 3.6\\\\[/tex]

This distance is approximate.
