Answers

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

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

11. If 2x+19=27, then 2x=8​

Answers

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 ☑️

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

What is the general equation of a Straight line?

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.

Lourdes plans to jog at least 1.5 miles. Write an inequality and solve an inequality to find x, the number of hours Lourdes will have to jog. She is running at 3.75 mph

Answers

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:

Step-by-step explanation:

you go down from the dot left most and you count towards the line that the second dot falls on and count over too it

Answer:

slope = - 3

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line

m = [tex]\frac{-1-2}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3

Write the rule for the linear function. Remember a function rule is written using f(x)

Answers

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

(0, -4)(2, 1)

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

A pair of Jordans sold at retail for $180 and now sell for $330 after market. A. Is this a percent INCREASE or DECREASE, what is the PERCENT change?

Answers

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%
