Identify the graph of the function described by the equation y = −4x + 5.
JulijaS [17]

As the equation is already in <em>y</em>=<em>mx</em>+<em>b</em>, all we need to do is use the equation to draw out a graph (or in this case, match with an already existing graph) using the y-intercept and slope. Since the y-intercept is 5, we can eliminate graphs C and D from our answers. We know the slope is -4, which means that our rise over run is -4 over 1. That would mean, to get from one point to the next, you go down 4 spaces and to the right one. This means the correct answer is graph B.

Manny buys a new grill that costs $375. The grill is discounted 22% and sales tax is 6.5%. How much does Manny pay for the grill
Svetllana [295]

Answer:

$310.05

Step-by-step explanation:

Method 1: Find the amount of 22% discount and subtract from original price, and find the amount of 6% tax and add to discounted price.

Original price: $375

Discount of 22%

22% of $375 = 0.22 × $375 = $82.50

Price after discount (but before tax): $375 - $82.50 = $292.50

Sales tax of 6%

6% of $292.50 = 0.06 × $292.50 = $17.55

Price after discount and tax: $292.50 + $17.55 = $310.05

Method 2: Add and subtract the discount percent and the tax percent first, then multiply.

Original price: $375

The discount is 22%.

The original price is 100%.

Subtract 22% from 100%: 100% - 22% = 78%

The discounted price is 78% of the original price.

Once you have the discounted price, tax is 6%.

The new discounted price is 100%. Add 6% to get 106%.

The price with tax is 106% of the discounted price.

106% of 78% of $375 = 1.06 × 0.78 × $375 = $310.05

Answer: $310.05

What is the value of n in 4n + 2 = 6(1/3n - 2/3)?
inysia [295]

4n + 2 = 6(1/3n - 2/3)?

Use distributed to remove parenthesis


4n+2=6(1/3n)+6(-2/3)

Solve right side

4n+2=2n-4


Subtract 4n from 2n


4n-2n+2=-4

Simplify

2n+2=-4

Subtract 2 from both sides

2n=-4+2

Simplify

2n= -2

Divide both sides by 2

2n/2=-2/2


And solve

N= -1
