Determine the slope and the y-intercept of the line represented by the equation y= -7/3×+3 slope: 7/9 ;y-intercept: 3 slope: 9/7
Mademuasel [1]

Answer:

slope ⟹ \:  -  \frac{7}{9}  \\ y  \:  intercept⟹ \: 3

Step-by-step explanation:

The standard form of this equation is

y = mx + c \\

m stands for the gradient or the slope, and c represents the y-intercept

y = mx + c \\ y =  -  \frac{7}{9} x + 3 \\ m =  -  \frac{7}{9}  \:  \\ and \:   \\  \: y \: intercept \:  = 3

For all real numbers a and b, 2a • b = a2 + b2 Is this true or false? Explain why it false or true.

This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9.

That's why it's false.

A department store is having a 15% off sale on all winter coats. You purchase a winter coat for $275. The department store is lo
sergeinik [125]

$275*.15(15%)=41.25 (this is the amount of the discount)

$275-$41.25=$233.75 (cost of jacket after discount)

$233.75* .0725=$16.946(round to $16.95, this is the amount of the sales tax).

If you want to know the total cost after tax just add $16.95 to the discounted price of $233.75. The price you pay for the jacket is $250.70.
