The number of miles that Mark ran was 50 miles.

We can get the number of miles that Mark runs by first assigning him the figure x.

Since DeSahwn ran 40. 7 miles less than Mark, we can express this thus:

x - 40. 7 miles.

If the number of miles that DeShawn ran was 9.3 miles we can factor that into the equation as follows:

x - 40. 7 miles = 9.3 miles

x = 9.3 + 40.7

x = 50 miles.

Therefore, the total number of miles that Mark ran was 50 miles.

The product of y and 5 is greater than or equal to - 20 is 5y ≥ -20

Inequalities are created through the connection of two expressions. It should be noted that the expressions in an inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.

In this case, the product of y and 5 is greater than or equal to - 20 will be:

(5 × y) ≥ -20

5y ≥ -20

This is the inequality.

1. Point slope form
2. y = -2x + 25

The formula for point slope form is:

y − y1 = m(x − x1), which is exactly what y-7=-2(x-9) is, as y1 is 7, m is -2 and x is 9.

To get this into slope intercept form, we have to solve for y/ isolate it.

y - 7 = -2 (x-9)

First, distribute the -2.

y - 7 = -2x + 18

Then add 7 on both sides to get rid of the -7.

+ 7 + 7

y = -2x+25

A portion of a square and a portion of a circle were used to create this figure. The perimeter of the figure is 36.28 units.

Given that,

A portion of a square and a portion of a circle were used to create this figure.

We have to find the perimeter of the figure.

Three linear sides are measured in units of 4, 8, 8, 4.

Radius of the circular part = 4 units

Measure of a polygon's circumference equals the polygon's perimeter.

From the figure we can see,

Figure perimeter equals the sum of the lengths of the three straight lines and the circumference of the quarter circle.

Measure of linear sides = 4 + 8 + 8 + 4 = 24 units

Circumference of the quarter circle = 1/4(2πr)

=1/2×π×4

=2×π

=2×3.14

=6.28 units.

Perimeter of the figure is 30+6.28

=36.28 units.

Therefore, the perimeter of the figure is 36.28 units.

Answer:

1/119

Step-by-step explanation:

119 is a whole number which you convert into 119/1 then the reciprical would be 1/119

The equation of a line into slope-intercept form is represented as:

y = mx + c

where m = slope of the line

c = y-intercept of the line

On simplifying 8x - 20y = 40, the equation will be:

⇒ 2 (4x - 10y) = 2 (20)

⇒ 4x - 10y = 20

⇒ 2x - 5y = 10

⇒ 2x - 10 = 5y

⇒ 5y = 2x + (-10)

⇒ y = 2x/5 + (-10/5)

⇒ y = 2x/5 + (-2)

The slope of this line = 2/5

y-intercept of the line = -2

Answer:

y = (4/5)x + 16

Point-slope form:

y - 12 = (4/5)(x + 5)

Step-by-step explanation:

slope = m; (-5, 12)

m = (4/5)    (x₁, y₁)

y - y₁ = m(x - x₁)

y - 12 = (4/5)(x - (-5))

y - 12 = (4/5)(x + 5)

y - 12 = (4/5)x + 4

Considering the cost of 3 bell peppers are $2.05, 4 tomatoes are $1.09, 2 onions are $0.65 and 5 potatoes are $0.33, and Giorgio used all these vegetables for his dinner, then his meal costed a total amount of $4.45.

As per the question statement, no information about the vegetables Gorgio used for his dinner or their prices are provided in the question statement, and thus we are considering that, Gorgio used 3 bell peppers that costed $2.05, 4 tomatoes at $1.09, 2 onions at $0.65 and 5 potatoes at $0.33 in his dinner recipe.

We are required to calculate how much does Gorgio's dinner meal cost.

To solve this question, we simply have to add up the prices of the ingredients and we will obtain our desired answer.

That is, Gorgio's  meal costed a total amount of $(2.05 + 1.09 + 0.65 + 0.33)

                                                                             = $4.45

Answer:

First and Third

Step-by-step explanation:

The graphs obey the function equations but the intervals are marked incorrect in #s 2 and 4

One thing to keep in mind is that when you have a piecewise function valid on certain intervals, the circle shape denoting the beginning of the interval is very important

If it is a filled circle it denotes a ≤ (or ≥) inequality

If it is an unfilled (hollow) circle it denotes a < (or >) inequality

Looking at the second graph we see that

f(x) = -1 for -∞ < x < -1
Assuming the interval is correctly defined, that solid circle at x = -1, y = -1 should be a hollow circle not a filled circle

Similarly for f(x) = 3x² + 3, the interval is given as -1 ≤ x < ∞ but the starting circle for this interval is an unfilled circle, it should be a filled circle

A similar situation applies to the fourth choice and you should be able to figure that out yourself

An inequality  | 2n -(- 1) | ≥ 10

                          | 2n + 1 | ≥ 10

after solving the inequality we get the value of n, n ≥  4.5  and n  ≤ - 5.5                                          

According to the question, given that

An inequality which has twice a number n is no less than 10 units from −1.

then inequality : | 2n -(- 1) | ≥ 10

                             | 2n + 1 | ≥ 10

So, 2n + 1 ≥ 10                   or              2n + 1  ≤ - 10

    2n  ≥  10 - 1                                      2n  ≤ - 10 - 1

    2n ≥  9                                              2n  ≤ - 11

    n ≥  4.5                                               n  ≤ - 5.5

Therefore, we get the value n, n ≥  4.5 and n =  ≤ - 5.5  after solving inequality.
