Answer:

[tex]m=2[/tex]

Step-by-step explanation:

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

Simply plug in 2 coordinates into the slope formula to find slope m:

(0, 0)

(1, 2)

[tex]m=\frac{2-0}{1-0}[/tex]

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

[tex]m=2[/tex]

Answer:

-7/4

Step-by-step explanation:

The slope of the line is -7/4

Answer:

= -7/4

Step-by-step explanation:

When we have 2 points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( -14-7)/(9- -3)

   = ( -14-7)/(9+3)

   = -21/12

Simplify

  = -7/4

Answer:

15

Step-by-step explanation:

If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,

4x-6+x=69

5x-6=69

5x=75

x=15

So, Maggie is 15.

Answer: Maggie is 15 years old

Step-by-step explanation:

69 = (4m - 6) + m     --- get an equation

69 - m = 4m - 6        --- lets subtract  m from both sides first

75 - m = 4m              --- add 6 on both sides

75 = 5m                    --- add m on both sides

15 = m                       --- divide by 5 on both sides

m = 15, so Maggie is 15 years old

Let's check:

69 = (4(15)-6) +15

69 = (60 - 6) + 15

69 = 54 + 15

69 = 69

Answer:

Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

Step-by-step explanation:

We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:

C1=15+2.5*x

The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:

C2=10+2.75*x

Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:

15+2.5*x=10+2.75*x

Simplifying:

-0.25x=-5

Solving:

x=-5/(-0.25)=20

Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

Answer:

Spencer is correct

Step-by-step explanation:

Because adding 4x to each side will bring both numbers to a positive and that makes it easier to get the answer

Answer:

Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Step 1:

5x + 4 = x + 12         Equation

Step 2:

4x + 4 = 12     Subtract x on both sides

Step 3:

4x = 8      Subtract 4 on both sides

Step 4:

x = 8 ÷ 4      Equation

Answer:

x = 2

Answer:

x=4

Step-by-step explanation

5x+4 = x+12

4x+4=12

4x=16

Answer:

Bed A --- Third Option

Bed B --- Fifth Option

Step-by-step explanation:

Flower Bed A)

The formula for circumference is:

[tex]C=2\pi r[/tex]

The diameter of A is 10 feet. So, its radius is 5 feet.

Substitute 5 for r. So, the circumference of Bed A is:

[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]

The formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

Substitute 5 for r:

[tex]A=\pi (5)^2[/tex]

Square and simplify:

[tex]A=25\pi \text{ square feet}[/tex]

So, the circumference of Bed A is 10π feet and its area is 25π square feet.

Therefore, match Bed A to the third option.

Flower Bed B)

The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:

[tex]C=2\pi (6)[/tex]

Multiply:

[tex]C=12\pi\text{ feet}[/tex]

Substitute 6 for r for the area formula:

[tex]A=\pi(6)^2[/tex]

Square and simplify:

[tex]A=36\pi\text{ square feet}[/tex]

So, Bed B has a 12π feet circumference and a 36π square feet area.

Therefore, match Bed B to the fifth option.

And we're done!

Answer:

4w +7 = 5

Step-by-step explanation:

Have a nice day.

Answer:

4w + 7 = 5

Step-by-step explanation:

"sum" means addition (+), so we're to add two items:

item 1 to be added

"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).

Therefore, 4 x w = 4w

item 2 to be added

This is the number 7

The sum

4w + 7

Now, the sum, equals(=)  the number 5, therefore answer:

4w + 7 = 5

Answer:

I believe that 11 students ate only the cookie.

Answer:

I think L = W/2A

Step-by-step explanation:

Answer:

A: [tex]L=\frac{2A}{W}[/tex]

Step-by-step explanation:

[tex]A=\frac{LW}{2}[/tex]

[tex]\frac{LW}{2}=A[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:}2[/tex]

[tex]\frac{2LW}{2}=2A[/tex]

[tex]LW=2A[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}W;\quad \:W\ne \:0[/tex]

[tex]\frac{LW}{W}=\frac{2A}{W};\quad \:W\ne \:0[/tex]

[tex]Simplify[/tex]

[tex]L=\frac{2A}{W};\quad \:W\ne \:0[/tex]

Variables that can only take on a finite number of values are called "discrete variables." All qualitative variables are discrete. Some quantitative variables are discrete, such as performance rated as 1,2,3,4, or 5, or temperature rounded to the nearest degree.

Answer:

2 tickets

Step-by-step explanation:

To be the same they must equal each other.

4.50 + 0.65x = 0.40x + 5

isolate the variable

subtract 4.50 from both sides

0.65x = 0.40x + 0.50

subtract 0.40x from both sides

0.25x = 0.50

divide both sides by 0.25

x = 0.50 ÷ 0.25

x = 2

Answer:

Option (B)

Step-by-step explanation:

Let the number of tapers in the basket = t

Number of pillars = p

And the number of jar candles = j

Tapers cost = $1 each

Jar candles cost = $6 each

Pillars cost = $ 4

Total number of candles in the basket = 8

Therefore, equation will be,

p + t + j = 8 -----(1)

Cost of the candles in the basket = $24

$1t + $4p + $6j = $24

t + 4p + 6j = 24 -------(2)

Since number of tapers is equal to the number of pillars and jar candles combined,

t = p + j

t - p - j = 0 ------(3)

Therefore, Option (B) is the answer.
