Step-by-step explanation:

SO find the slope first

ANd then just fill out the point slope formula

Answer:

8.50 gallons of gas.

Step-by-step explanation:

The slope in this scenario is -1.25 gallons per mile, this means that for every mile that Evin drives she is wasting 1.25 gallons of gasoline. Since she only drove 1 hour at the begining and after that hour her tank had 7.25 gallons, then we can simply add 1.25 gallons to her tank at this moment to make up for the 1 hour she drove and that would give us the total amount of gas she had before she started driving.

7.25 + 1.25 = 8.50 gallons of gas.

Evin was losing gas at a rate of 1.25 gallons per hour and she started with 8.5 gallons.

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the amount of gallons left after x hours.

She notices that after 1 hour her gas tank has 7.25 gallons left. Hence:

7.25 = m(1) + b

m + b = 7.25   (1)

After 4 hours of driving, it has 3.5 gallons of gas left in it. Hence:

3.5 = 4(m) + b

4m + b = 3.5   (2)

Solving equations 1 and 2 simultaneously gives m = -1.25, b = 8.5

Hence Evin was losing gas at a rate of 1.25 gallons per hour and she started with 8.5 gallons.

Step-by-step explanation:

Looking at the graph, we can see the roots at two points

these are points x = 4 and x = 5

This can be written in their linear forms as;

x-4 and x-5

Finding the products of both, we have

x(x-5) -4(x-5)

= x^2 -5x -4x + 20

= x^2 - 9x + 20

Answer:

5 units

Step-by-step explanation:

Let point O be the point of intersection of the kite diagonals.

|OF| = 2, |OH| = 5

|FH| = |OF| + |OH| = 2 + 5 = 7

FH and EG are the diagonals of the kite. Hence the area of thee kite is:

Area of kite EFGH = (FH * EG) / 2

Substituting:

35 = (7 * |EG|) / 2

|EG| * 7 = 70

|EG| = 10 units

The longer diagonal of a kite bisects the shorter one, therefore |GO| = |EO| = 10 / 2 = 5 units

x = |GO| = |EO| = 5 units

Answer:

5 units

the correct answer is true

Answer:

1. 1 Burrito Platter = $58.50 , 1 Taco platter = $12.50

2. One pair of boots = $20 , One pair of shoes = $6

Step-by-step explanation:

1. Let the cost of one burrito platter be x and one taco platter be y.

4x + 2y = 259 --- Equation 1

4x + 4y = 284 --- Equation 2

Equations 2-1: 4x + 4y - 4x - 2y = 284 - 259

2y = 25

y = 25 ÷ 2

y = 12.50 (Taco platter)

Substitute y = 12.50 into Equation 1:

4x + 2y = 259

4x + 2(12.50) = 259

4x + 25 = 259

4x = 259 - 25

    = 234

x = 234 ÷ 4

x = 58.50 (Burrito platter)

2. Let the cost of one pair of boots be x and one pair of shoes be y.

7x + 8y = 188 --- Equation 1

6x + 8y = 168 --- Equation 2

Equations 1-2: 7x + 8y - 6x - 8y = 188 - 168

x = 20 (Boots)

Substitute x = 20 into Equation 2:

6x + 8y = 168

6(20) + 8y = 168

120 + 8y = 168

8y = 168 - 120

    = 48

y = 48 ÷ 8

y = 6 (Shoes)

If you know about the power rule,

d/dw (2w² + 1) = 2 d/dw (w²) = 2 • 2w = 4w

If you have to use the limit definition of the derivative, let f(w) = 2w² + 1. Then

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{f(w+h)-f(w)}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{(2(w+h)^2+1)-(2w^2+1)}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{2(w^2+2wh+h^2)-2w^2}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{4wh+2h^2}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}(4w+2h)=\boxed{4w}[/tex]

[tex]\frac{students}{total} = \frac{percent}{100percent}[/tex]

[tex]\frac{x}{480students} =\frac{95percent}{100 percent}[/tex]

x * 100 = 480 * 95

x = 45600 / 100 = 456

95% of 480 students is 456 students.

Answer:

The system of inequalities are;

p + s ≥ 5

22.49s + 34.99p ≤ 200

Where P represents number of dress pants and s represents the number of sweaters

Step-by-step explanation:

Here, we want to write system of inequalities

Let the number of sweaters be s and the number of pants be p

She wants to purchase at least 5 items

When we have at least, it means that it might be greater than or equal to that value

Thus;

p + s ≥ 5

Secondly, at most the amount to be spent is the value on the gift card which is 200

Thus;

we have;

Step-by-step explanation:

Given that:

Money spent on clothing last month = $40

Money spent this month is 120% of the spending of the last month.

To find:

A proportion to model this situation.

And the spending done this month?

Solution:

Let us have a look at 120% first.

[tex]120\%= \dfrac{120}{100} = \dfrac{6}{5}[/tex]

[tex]\frac{6}{5}[/tex] of [tex]x[/tex] can be found by comparing [tex]x[/tex] with 5, then we have to find the equivalent of 6.

Here, [tex]x[/tex] is 40.

5 parts are equivalent to 40

1 part is equivalent to [tex]\frac{40}{5} = 8[/tex]

6 parts are equivalent to [tex]8\times 6 = 48[/tex]

OR

simply:

[tex]40 \times \dfrac{120}{100} = 48[/tex]

Answer:

Length of shorter leg is 8 inches

Step-by-step explanation:

Here, we want to calculate the length of the shorter leg of a 30-60-90 triangle

In a 30-60-90 triangle, the sides are in the ratio;

1: √3 : 2

So the ratio of the length of the shorter and longer leg is;

1 : √3

So in this case let the shorter leg be x

x/8 √3 = 1/√3

8 √3 * 1 = √3 * x

x = 8 √3/√3

x = 8 inches

x=8

Answer:

(15,-30)

Step-by-step explanation:

By forming a proportional relationship with the marked point, what we are saying is that the same dilation if applied to each coordinates of the marked point will form the new point

The marked point is given as (-20,40)

If we dilate this by -0.75 units

That will give (15, -30)

So this forms a proportional relationship with the marked point
