Answer:

[tex]5y=-x+23\\[/tex]

Step-by-step explanation:

Since the equation of the line is perpendicular to the line y = 5x +6

we can use the formula:

[tex]m_1m_2=-1\\[/tex]

where m1 is the slope of the line we have and,

m2 is the slope of the line we need

so here m1 is 5 as we compare it with the slope-intercept form our slope is:

[tex]y=5x+6\\y=mx+b[/tex]

our m1 is 5 but we need m2 so plugging in the value we get m2 to be:

[tex]m_1m_2=-1\\5m_2=-1\\m_2=-1/5\\[/tex]

and now we have our m2, now furthermore since the line passes through the point (-2 , 5) it means the point must lie on the line and satisfy it. We can use this point and the slope m2 and find out the equation by the point-slope form equation:

[tex]y-y_1=m(x-x_1)\\y-5=-\frac{1}{5}(x-(-2))\\\\5(y-5)=(-1)(x+2)\\5y-25=-x-2\\5y=-x-2+25\\5y=-x+23\\[/tex]

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;

22.49s + 34.99d ≤ 200

Answer:

The average cost of one mango = c = ₦8

Step-by-step explanation:

Let 'c' be the average cost of one mango

The original amount Idahtonye has = ₦50.00

The amount of mangoes Idahtonye buys = 6 mangoes

As he gets back the change of ₦2 after paying ₦50.00 to buy 5 mangoes.

Thus the equation becomes

50 - 2 = 6c

48 = 6c

dividing both sides by 6

48/6 = 6c/6

c = 8 ₦

Therefore, the average cost of one mango = c = ₦8

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.

Answer:

Step-by-step explanation:

The equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx + b becomes y = 0x +b y = b. Also ,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.

Answer:

Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.

Step-by-step explanation:

Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.

Answer:

4/3 yards

Step-by-step explanation:

Given that:

Area of rectangle = 2/3 yd²

Width = 1/2 yards

The length of the rectangle =?

Let length of rectangle = x

Recall :

Area of rectangle = Length * width

2/3 = x * 1/2

2/3 = x/2

Multiply both sides by 2

2/3 * 2 = x/2 * 2

4 /3 = x

Hence, length of the rectangle = 4/3 yards

Answer with what

Step-by-step explanation:

Answer:

9.2

Step-by-step explanation:

Since it is a right triangle, we can use pythagorean theorem to figure out the hypotenuse length.

a^2 + b^2 = c^2

6^2 + 7^2 = c^2

36 + 49 = c^2

c^2 = 85

square root both sides get

c= 9.219, rounded to nearest tenth is 9.2

Answer: $30

Step-by-step explanation:

Let the amount paid to water the yard be represented by x.

Since her mother pays her twice as much to mow the yard as she does to water the yard. Therefore, the amount to mow the yard would be 2x.

Therefore,

2x + x = $45

3x = $45

x = $15

The amount to mow the front yard would be:

= $15 × 2

Answer:

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

Step-by-step explanation:

The ladder will reach 11.82 ft high of the wall of his house.

The situation will form a right angle triangle. Therefore,

The length of the ladder is the hypotenuse of the triangle formed.

The height of the wall is the opposite side of the triangle.

Therefore,

using trigonometric ratio,

sin 80°  = opposite / hypotenuse

sin 80° = h / 12

cross multiply

h = 12 sin 80°

h = 12 × 0.98480775301

h = 11.8176930361

height of the wall ≈ 11.82 ft

Given that:

Quantity of squash that each person gets = [tex]\frac{3}{4}[/tex] pounds

Total quantity of squash present = 9 pounds

To find:

The total number of people such that the squash can be evenly split.

Solution:

To find the total number of people such that the squash can be evenly split, we need to divide the total quantity of squash with the quantity of squash that each person gets.

Therefore, the dividend is the total quantity i.e. 9 pounds.

Divisor is the quantity that a person gets i.e. [tex]\bold{\frac{3}{4}}[/tex].

The division problem is:

[tex]\dfrac{9}{\frac{3}4}[/tex]

It can be written as:

[tex]\dfrac{9\times 4}{3}\\\Rightarrow \bold{12 }[/tex]

The quotient is 12.

Answer:

The solution set is {x : x ∈ R, x < -7} ⇒ A

Step-by-step explanation:

Let us solve the question

∵ x + 2 < -5

→ Subtract 2 from both sides of the inequality

∴ x + 2 - 2 < -5 - 2

∴ x + 0 < -7

∴ x < -7

→ By using the second rule above

∴ The solution set is {x : x ∈ R, x < -7}

Answer:

Option (D) is correct.

Step-by-step explanation:

We know that exponential decline in Math can be termed as a consistent reduction of an amount by percentage over a certain period of time.

It can be expressed using the formula

y = a (1-b)ˣ

here

Now, map our problem using the same concept formula

as

3000 students were enrolled, so

as High School has been experiencing an annual  decline of 2.2% in enrollment, so

so substituting b = 0.022 and a = 3000

y = a (1-b)ˣ

y = 3000 (1 - 0.022)ˣ

as

so the expression becomes

y = 3000 (0.978)ˣ

Therefore, option (D) is correct.
