Answer:

The third option is the answer.

Step-by-step explanation:

In the formula y = mx + b, using the equation given,

Answer:

the 3rd option

Step-by-step explanation:

In the formula y = tx + b, using the equation given,

t = 2, which means that the line goes up 2 units and right 1 unit.

b = 1, which means that the y-intercept, or where the line touches the y-axis, is 1.

Answer:

F. Outta. Here

Step-by-step explanation:

Answer:

a. 260m

b. 50m

Step-by-step explanation:

First, triangle POQ and triangle PNR are similar triangles, b/c they have one same angle(OQP), and OQ//NR.

Therefore, OP/OQ = NP/NR.

NP = OP + ON = 175 + 175 = 350

(a) 175/130 = 350 /NR, NR = 260

(b) 175/ (X+10) = 350/ (3X+5) , x = 15, NR = 50

Answer:

Vertical change= 1

Horizontal change= 2

Rate of change=  1/2

Step-by-step explanation:

The vertical change is how many units you go up on the triangle and the horizontal change is how many units you go left or right on the triangle. The rate of change is the vertical change over the horizontal change. So that is why 1/2 is the rate of change. Have a great day!

Step-by-step explanation:

Answer:

1/2x-18

Step-by-step explanation:

18 subtracted from half of a number

We assume that the "number" is x

so 1/2x is the half of a number

We now need to have 18 subtracted from that so 1/2x-18

Step-by-step explanation:

Answer:

He will cover 2,827.433 feet² area of the park with plant food.

Step-by-step explanation:

The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.

diameter= 60 feet

radius = diameter/ 2= 60/2= 30 feet

The area of the circle can be found by the formula πr²

Area= πr²=π(30)²

 Area = 900π= 2,827.433 feet²

He will cover 2,827.433 feet² area of the park with plant food.

Answer:

d = 8/3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given

Area of the rectangle =Length × width

Given

The desired length of the lot is 6 m longer than its width, then L = 6+W

A = LW

40 = (6+W)W

40= 6W+W²

W²+6W -40 = 0

W²+10W-4W-40 = 0

W(w+10)-4(w+10) = 0

W+10 = 0 and w-4 = 4

W = -10 and w = 4

Width can't be negative

W = 4m

Since L = 6+w

L = 6+4

L = 10m

Hence the possible dimension s 4m by 10m

Answer:

[tex]a^{2} b^{2}[/tex] (9[tex]a^{2} b^{2}[/tex] + 1)

Step-by-step explanation:

simplify (3a²b²)²+(ab)²​; for the first term, square the 3 and multiply the exponents by 2, also multiply the exponents by 2 in the second term

[tex]9a^{4} b^{4} + a^{2} b^{2}[/tex] ; factor out [tex]a^{2} b^{2}[/tex]

Answer:

82

Step-by-step explanation:

Evaluate 10z² - 2z - 2 where z = 3:

[tex] \longrightarrow [/tex] 10z² - 2z - 2 = 10 × 3² - 2 × 3 - 2

3² = 9:

[tex] \longrightarrow [/tex] 10 × 9 - 2 × 3 - 2

10 × 9 = 90:

[tex] \longrightarrow [/tex] 90 - 2 × 3 - 2

-2 × 3 = -6:

[tex] \longrightarrow [/tex] 90 - 6 - 2

90 - 6 - 2 = 90 - (6 + 2):

[tex] \longrightarrow [/tex] 90 - (6 + 2)

6 + 2 = 8:

[tex] \longrightarrow [/tex] 90 - 8

[tex] \longrightarrow [/tex] 82

Answer:

The mean.

Step-by-step explanation:

The mean because 50 is a lot bigger number than the numbers in the list.

The median (the middle number in an ordered list) would still be 15. Also the mode (15) will also stay the same.

The original mean = sum of the 6 numbers divided  by 6

= 92/5 = 15.3.

When 50 is added the mean is (92 + 50) / 7 =  20.3.

Answer:

The mean

Step-by-step explanation:

Because mean is the main measure of center that we solve first before solving the others

Answer:

7:4

Step-by-step explanation:

11-7=4

7:4

The ratio of old books to the new books is new : old = 7 : 4.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, There are 11 books on a shelf, and 7 of these books are new.

So, The number of old books are (11 - 7) = 4.

So, In the self there is 7 new books and 4 old books.

Therefore the ratio of new books to old books,

new books : old books = 7 : 4.

17 years old.

Step-by-step explanation:

sisters age:5

5×3+2=17.

Answer:

Liza is 17 years old.

Step-by-step explanation:

Ley 'x' be the age of Liza's younger sister

so the equation of Liza's age will be:

Liza's age = 3x+2

As x = 5 years is Liza's younger sister age

so

Liza's age = 3(5)+2

                 = 15+2

                  = 17 years

Therefore, Liza is 17 years old.

Answer:

The slope would be 5

Step-by-step explanation:

The reason why it would be five is because the slope formula is y=mx+b with m being your slope and b being your y-intercept.

Answer:

slope: 5

Step-by-step explanation:

[tex]y=mx+b[/tex] is the equation used to find the slope of an equation. The slope is ALWAYS the "m" value. So.... in this equation y=5+2/5... the "m" value is 5.... making the slope of the equation 5.

Answer:

(8, 25) and (14, 50)

Step-by-step explanation:

Total cost of a set of cards = price per unit x number of cards

                                             = p x n

Thus, the total cost of printing each set of cards depends on the price per unit and number of cards. So that it can be represented in ordered pair as: (p, n).

For the first set of greeting cards,

the cost of printing a card = $8.0

number of cards printed = 25

This can be represented in ordered pair as (8, 25)

For the second set of greeting cards,

the cost of printing a card = $14.0

number of cards printed = 50

This can be represented in ordered pair as (14, 50)

Thus, the two ordered pairs that can represent the situations are (8, 25) and (14, 50).

Y = [tex]x^{2}[/tex] - x - 42

Answer:cot t = 1.875

[tex]sin t=\frac{-8}{17}[/tex] but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t

⇔cos t = [tex]\sqrt{1-sin^{2}t }=\sqrt{1-(\frac{-8}{17})^{2} }=|\frac{15}{17}|[/tex]

but  t is a quadrant III angle => cos t = [tex]\frac{-15}{17}[/tex]

=> cot t = [tex]\frac{-15}{17}:\frac{-8}{17}=\frac{15}{8}=1.875[/tex]
