Georgia [21]3 years ago

Answer:

y = mx + b

m = (-7 - -5) / (5 - 4) = -2

y = -2x + b

Use either point to find b

Using (4, -5):

-5 = (-2)(4) + b

-5 = -8 + b

b = 3

y = -2x + 3

Seth bought a 12 - ounce jar of peanut butter for $3.60. What is the unit price?
allochka39001 [22]

Since the jar is 12 ounces, we want to find the price when it is one ounce. We do this by dividing the price, $3.60, by 12:

3.60/12 = 0.3

So, the answer is $0.30/oz, or (B).

Solve the system of equations for the variables: 5x+2y=13 x+2y=9
r-ruslan [8.4K]

Answer:

x = 1

y = 4

Step-by-step explanation:

5x + 2y = 13

x + 2y = 9

Add both equations.

6x + 4y = 22

Solve for x.

6x = 22 - 4y

x = 22/6 - 4/6y

Put x as 22/6 - 4/6y in the second equation and solve for y.

22/6 - 4/6y + 2y = 9

-4/6y + 2y = 9 - 22/6

4/3y = 16/3

y = 16/3 × 3/4

y = 48/12

y = 4

Put y as 4 in the first equation and solve for x.

5x + 2(4) = 13

5x + 8 = 13

5x = 13 - 8

5x = 5

x = 5/5

x = 1

Danielle earns a 7.75% commission on everything she sales at the electronic store where she works. She also earns a base salary
Andrew [12]

The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775

($4,100 × 0.0775 + $4,100 ) + $600

Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).

P = Parenthesis

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subrtaction

$4,100 × 0.0775 + $4,100 ) + $600

$4,417. 75 + $4,100 + $600

$4,417. 75 + $600 = $5,017.75

Danielle made $5,017. 17 last week.

I hope this helps! :)
