Step-by-step explanation:

We can see point on the graph:

(0, 5) and (4, 3)

Slope-intercept form:

y = mx + b

First finding the slope using slope formula:

m = (y2-y1)/(x2-x1) = (3 - 5)/(4-0) = -2/4 = -1/2y -intercept is 5 as per the first point

Crystal earns $5.50 per hour mowing lawns.
• Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
• How much does Crystal earn if she works 3 hours and 45 minutes

Answers

1) Required equation
2)Crystal earns $20.625 in 3 hours and 45 minutes.
Step-by-step explanation:
Given : Crystal earns $5.50 per hour mowing lawns.
To find :
1) Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
It is given that Crystal earns $5.50 per hour mowing lawns.
Let m is the amount of money earned
and h is the number of hours spent
So, The equation form by the statement is

2) How much does Crystal earn if she works 3 hours and 45 minutes
1 hour=60 minutes
So, for 3 hours and 45 minutes

In 1 hour she earn $5.50
In 3.75 hours she earn

Answers

Answer:

[tex]a \: 3x - 6 \\ b \: 2y + 8 \\ c \: 8x + 24[/tex]

Step-by-step explanation:

All we have to do is multiply accordingly. I'll use a for an example.

So for the value before the perentheses we multiply that by all of the values in the perentheses.

[tex]3x \: and \: - 6[/tex]

So the correct answer would be

[tex]3x - 6[/tex]

You can use the same strategy for all the questions, but I'll just answer those straight away.

Also you may notice I put the variable before the constant in question c because the variable should always go before the constant in expressions and equations.

The answer is 3x-6 i really hope this helped :)

Abe is buying wrapping paper.
He is shopping for the best deal.

Drag the rolls of wrapping paper in order from the least to the greatest unit cost in dollars per square foot.
red 12.5 square feet for $1.79
blue 40 square feet for $5.29
green 50 square feet for $8.49
orange 60 square feet for $6.00

Answers

Answer:

So you need to compute all the rates to see which is the best deal.

$1.79/12.5ft^2=$0.1432 per ft^2

$5.29/40ft^2=$0.13225 per ft^2

$8.49/50ft^2=$0.1698 per ft^2

$6/60ft^2=$0.10 per ft^2

So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.

Sherbert, blue, red, and green

Step-by-step explanation:

Answer:

The order goes Orange, Blue, Red, and Green

Step-by-step explanation:

By dividing the total cost by the amount of square feet, you get the unit value for the wrapping paper per square foot.

A quadratic equation that has X-intercepts of (-2,0) and (8,0), a stretch of 3, and the vertex is a minimum.
a. Factored form equation:
b. Vertex form equation:
c. Standard form equation:

Answers

Answer:

a. y = 3 × (x + 2)(x - 8)

b. y = 3·(x - 3)² - 75

c) y = 3·x² - 18·x - 48

Step-by-step explanation:

The x-intercept of the quadratic equation are (-2, 0), (8, 0)

The stretch of the quadratic equation = 3

We have;

a. The factored form y = 3 × (x + 2)(x - 8)

b. From the vertex form, we have;

y = 3 × (x + 2)(x - 8) = 3·x² - 18·x - 48

y = 3·x² - 18·x - 48

The vertex form a(x - h)² + k

Where;

h = -b/(2·a) = 18/6 = 3

h = 3

k = c - b²/(4·a) = -48 - (18²)/12 = -75

The vertex form 3·(x - 3)² - 75

c) The standard form of the quadratic equation, y = a·x² + b·x + c

The standard form of the quadratic equation is y = 3·x² - 18·x - 48.

Where are the 4th roots of 16i located?

b) on a circle with radius 2
c) on a circle with radius 2.5
d) on a circle with radius 4

Answers

Answer:

B) on a circle with radius 2

Step-by-step explanation:

got it right on edge :)

The 4th roots of 16i is located b) on a circle with radius 2

How to determine the location of the fourth root?

The complex number is given as:

Number = 16i

Take the fourth root

[tex]Root = \sqrt{16i[/tex]

Take the fourth root of 16

[tex]Root = 2\sqrt{i[/tex]

The number before the radicand represents the circle radius

Hence, the 4th roots of 16i is located b) on a circle with radius 2

Sean wants to spend (example) $100 on clothing and he wants to purchase
6 additional items for his wardrobe. Each pair of pants costs $20 and each shirt costs $15.
Show the solution graphically.

Point (2, 4)

Answers

Answer:

Step-by-step explanation:

Let x be the number of pants and y be the number of shirts

x + y = 6

20x + 15y = 100

multiply the first equation by -20

-20x -20y = -120

20x + 15y = 100

subtract the equations

-5y = -20

y = 4

replace y in equation 1

x + 4 = 6

x = 2

Which of these equations is NOT true?
A) 2(a + b) = a +b+a+b
C) (t-4) +6=t-10
B) 3y + 4y = 7y
D) x(5 + 9) - x = 13x

Answers

Answer:

C) (t-4) + 6=t-10

Step-by-step explanation:

2(a+b)= a+b+a+b

2(a+b)= 2a+b+b

2(a+b)=2a+2b

2(a+b) = 2(a+b)✅

(t-4)+6=t-10

t+2=t-10❌

3y+4y=7y
