Can someone explain how to do this I'm lost.

Answer:

y=-8/7x-4

from, m1m2=-1

-8/7m2=-1

m2=7/8

again from, m=(y-y1)/(x-x1)

7/8=(y-9)/(x-10)

8(y-9)=7(x-10)

8y-72=7x-70

8y=7x-70+72

8y=7x+2

therefere,

y=7/8x+1/4

Answer:

This is a percent INCREASE

The percent change is 83.33%

Step-by-step explanation:

Let us solve the question

∵ A pair of Jordans sold at retail for $180

∴ The initial price = 180

∵ Now it sells for $330 aftermarket

∴ The new price = 330

→ That means the new price is greater than the initial price

∵ The new price is greater than the initial price

∴ This is a percent INCREASE

∵ The percent of change = (amount of increase ÷ initial amount) × 100%

∵ The amount of increase = new price - initial price

∴ The amount of increase = 330 - 180 = 150

→ Substitute it in the rule of percent of increase above

∵ The percent change = [tex]\frac{150}{180}[/tex] × 100%

∴ The percent change = [tex]\frac{5}{6}[/tex] × 100%

∴ The percent change = 83.33%

Answer:

The out-of-state tuition would be $8800.

Step-by-step explanation:

Given that:

The ratio of in-state tuition to out-state tuition = 3:11

If the tuition of in-state is $2400.

Let,

x represent the number of out-of-state tuition.

As the relation is directly proportional.

3 : 11 :: 2400 : x

Product of mean = Product of extreme

11*2400 = 3x

3x = 26400

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{26400}{3}\\x=8800[/tex]

Hence,

The out-of-state tuition would be $8800.

Answer:

51

m = 6 and n = 5

Now

m² + 3n

= ( 6) ² + 3 * 5

= 36 + 15

= 51

Answer:

8

Step-by-step explanation:

Cross reduce, you then get:

12x+48=18x

12x-18x=-48

-6x=-48

x=8

Answer:

100% true....

subtracting 19 from both sides brings you to 2x=8, so x=4

Step-by-step explanation:

Hey there!

2x + 19 = 27

SUBTRACT by 19 to BOTH SIDES

2x + 19 – 19 = 27 – 19

Cancel out: 19 – 19 because that gives you 0

KEEP: 27 – 19 because that gives you the value of 8

New EQUATION: 2x = 8

DIVIDE by 2 to BOTH SIDES

2x/2 = 8/2

CANCEL out: 2/2 because that gives you 1

KEEP: 8/2 because that gives you the value of x

“8/2 = x”

Answer: x = 4 ☑️

Good luck on your assignment and enjoy your day!

Answer:

1.5 ≤ 3.75x

Step-by-step explanation:

Given that:

Distance, D to jog is atleast 1.5 miles

D ≥ 1.5 miles

x = number of hours to jog

Jog rate = 3.75 mph

Actual distance covered if jog last for X hours

Actual Distance = speed * time

Actual Distance = 3.75 * x = 3.75x

Hence,

D ≤ Actual distance

1.5 ≤ 3.75x

Answer:

[tex]consider \: triangle \: BDE \\m<BCD = m<BED \\ angles \: of \: triangle \: sum \: up \: to \: 180 ° \\ (14x + 4)° + 55° + 51° = 180° \\ 14x = 180° - (4 + 55 + 51)° \\ 14x = 70° \\ x = \frac{70}{14} \\ x = 5[/tex]

Answer:

x = 5

Step-by-step explanation:

all angles at corners in parallelogram must add to 360

bcd = 51 thus angle at opposite corner (bed) must also equal 51

adding = 51 + 51 = 102

angles at ebc and edc are also equal to each other

edf = 55 and cbf = 55

adding 55+55 = 110

360 - 110 - 102 = 148

divide by 2 for angles ebf and cfd

148/2 = 74

now solve

14x + 4 = 74

14x = 70

x = 5

y=mx+b

M=slope

B=y-intercept

Answer:

Slope: 5x    Y-Intercept: -7

Step-by-step explanation:

The slope is the rate at which it increases, the y-intercept is the point in the graph that crosses the y-axis

y=mx+b  

mx = slope

b = y-intercept

Answer:

The rule for the linear function will be:

f(x) = 5/2x - 4

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points

Finding the slope between (0, -4) and (2, 1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [1 - (-4)] / [2 - 0]  

                 = 5 / 2

Thus, the slope of the line = m = 5/2

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = -4

Thus, the y-intercept b = -4

Now, substituting m = 5/2 and b = -4 in the slope-intercept form of linear function

y = mx+b

y = (5/2)x + (-4)        ∵ m = 5/2, b = -4

y = 5/2x - 4

or

f(x) = 5/2x - 4     ∵  y = f(x)

Therefore, the rule for the linear function will be:

f(x) = 5/2x - 4

B

Graph [2] represents the correct relationship between Weeks and Money saved by Samantha.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is Samantha who created part of a table to show her savings. She saved at the same rate each week.

We have, Samantha’s Savings as -

Week                      1               2                  3                4

Money Saved       A               B                $18            $24

Since she saves at the same rate every week, therefore, the slope of the line will be -

m = (24 - 18)/(4 - 3)

m = 6/1

m = 6

Then -

A = 6

B = 12

The graph [2] represents the correct graph.

Therefore, graph [2] represents the correct relationship between Weeks and Money saved by Samantha.
