Step-by-step explanation:

Slope-intercept form: y = mx + c

We have m = 1/4. Since it passes through the

point (-4, 2), => When x = -4, y = 2.

=> (2) = (1/4)(-4) + c, 2 = c - 1, c = 3.

Hence the equation is y = x/4 + 3.

Max was on vacation twice as long as Jared and half as longas Wesley. The boys were on vacation a total of 3 weeks. How many day
lord [1]
Make an equation.
Also, convert 3 weeks into days ⇒ 3 · 7 = 21 days.

x + 2x + 4x = 21

x is Jared.
2x is Max (because half of 4 is 2).
4x is Wesley.

Now solve the equation.

7x = 21
x = 3

Jared = x
Max = 2x
Wesley = 4x

Jared = 3 days
Max = 2(3) = 6 days
Wesley = 4(3) = 12 days

CHALLENGE PROBLEM Danny's Department Store advertises savings of
Oksanka [162]

Discount are used to reduce the costs of items

The percent paid to determine the advertisement is incorrect

<h3>How to determine the correct percentage</h3>

The initial prices are given as: $44.00 to $152.00

And the discount is: 45% to 51%

At a discount of 45%, the price of the items would be:

Price = \$44.00 * (1 - 45\%)

Price = \$24.2

Price_2 = \$152.00 * (1 - 45\%)

Price_2 = \$83.6

At a discount of 51%, the price of the items would be:

Price = \$44.00 * (1 - 51\%)

Price = \$21.56

Price_2 = \$152.00 * (1 - 51\%)

Price_2 = \$74.48

The calculates prices show that the percent paid to determine the advertisement is incorrect

5) 10r2 + 3 = 813<br><br>how do I solve by square roots ​
kodGreya [7K]

10r² + 3 = 813

10r² = 813 - 3

10r² = 810

r² = 810 ÷ 10

r² = 81

r = √81

r = <u>9</u>

So, the value of <em>r </em>is 9
