Answer 2

Answer:

14 10 cent coins

Step-by-step explanation:

Assumption method:

Assume all are 10 cent

10x48=$4.80

8.20-4.80=3.40

10x47=$4.70

1x20=$0.20

$4.70+$0.20=$4.90

Gap= $3.40

Difference=$4.90-$4.80=$0.10

Gap÷Difference= $3.40÷0.10=34 20 cent coins

48-34=14 10 cent coins

I think its like this.

Answers

Answer:

$68.74

Step-by-step explanation:

Original: $99.99

New: x

Tax: $8.75

Discount : 40%

Discounts are applied before tax.

40% of 99.99 = 0.40(99.99) = 39.996

99.99 - 39.996 = 59.994

Apply tax:

59.994 + 8.75 = 68.744 ≈ 68.74

Kareem wanted to write an equation for his friend that has many solutions. Help him write an equation.

Answers

Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions

Step-by-step explanation: (x+2) = 0 only has one solution.

(x+2)*(x-4) = 0 has two solutions, -2 and 4

(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc

If "many" means more than three, then add another (x+XX) term. A quadratic equation generally has two solutions.

Given the points (0, -1) and (6, 1), we need the following information to solve for the equation of the line:

We need the slope and the y-intercept.

Let (x1, y1) = (0, -1)

(x2, y2) = (6, 1)

Substitute these values into the following slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - (-1)}{6 - 0} = \frac{1 + 1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]

Therefore, the slope (m) = 1/3.

Next, we need the y-intercept, (b), which is the point on the graph where it crosses the y-axis. It is also the value of the y-coordinate when its corresponding x-coordinate = 0.

Looking at one of the given points, (0, -1), this represents the y-intercept. Therefore, the y-intercept (b) = -1.

Now that we have our slope, m = 1/3, and y-intercept, b = -1, we can write our linear equation in slope-intercept form as:

y = 1/3x - 1

Step-by-step explanation:

Slope intercept form: y = mx + b
