The slope is 4, and the y-intercept is 2.

Answers

Answer:

slope(m)=4 and

y-intercept(c)=-5/2

Step-by-step explanation:

here,8x-2y=5

reducing it into slop intercept form we get,

2y=8x-5

or,y=8/2x+(-5/2)

or,y=4x+(-5/2)

comparing it with y=mx+c we get,

slope(m)=4 and

y-intercept (c)=-5/2

b=(0,y)

b=6

yo y= -1/5 + 6

Answer:

y= -5x +6

pick ANY two points from the graph:

(0,6) and (1,1)  

first you need to find the slope:

Y2 - Y1      6 - 1       5

----------  =  ------- = ----- = -5

X2 - X1      0 - 1      -1

y = -5x + b

the Y-intercept is (0,6):

Paul is locked out of his house. An 18-ft ladder is outside and an upstairs window is open. Paul read the safety warning on the ladder recommending it be placed six feet away from the wall. He placed the ladder according to the warning and it reached the base of the window. How high is the base of the window off the ground?

Answers

Answer:

17.0 ft

Step-by-step explanation:

Let h be the height of the base of the window from the ground, L be the length of the ladder = 18 ft and d be the distance of the ladder from the wall = 6 ft. Now, these three lengths form a right-angled triangle with the length of the ladder, L as the hypotenuse side.

So, using Pythagoras' theorem,

L² = h² + d²

So, h = √(L² - d²)

Substituting the values of L = 18 ft and d = 6 ft, we have

h = √((18 ft)² - (6 ft)²)

= √(324 ft² - 36 ft²)

= √288 ft²

= 16.97 ft

≅ 17.0 ft

through (2, -4) and parallel to y= 9/2x+3

Answers

Answer:

y=[tex]\frac{9}{2\\}[/tex] x-13

Step-by-step explanation:

first, since it's parallel the slope has to be the same and the y-intercept has to be different.

you will have y=9/2x+b

find b, by using the points you are given so you will get

-4=(9/2) times (2)+b.

then when sloving you will get b=-13 and so the full equation will be

y=9/2x-13

Answers

Answer:

x = 7

Step-by-step explanation:

QY = 5x

YZ = 18

QZ = 53

Thus:

QY + YZ = QZ (segment addition postulate)

5x + 18 = 53

5x = 53 - 18 (subtraction property of equality)

5x = 35

Divide both sides by 5

Answers

Answer:

no tengo ni idea

Step-by-step explanation:

The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.

What is the area of the triangle?

Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,

A = (1/2) × h·b

The coordinates of the triangle will be (x₁, y₁), (x₂, y₂), and (0, 0).

The length of the base of the triangle will be given as,

Base = (x₂ - x₁)

The height of the triangle is given as,

Height =  (y₂ - 0) or (y₁ - 0)

Height =  y₂ or y₁

The area of the triangle will be given as,

A = (1/2) × (x₂ - x₁) × y₁

A = (1/2) y₁(x₂ - x₁)

The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.

Marshall gave the cashier $100 to pay for 4 new video games. The cashier gave him $4.08 in change. Each video game cost the same amount.

What is the cost in dollars and cents for each video game?
PLZZZZ HELP

Answers

Answer:

I would say it's $23.98

Step-by-step explanation:

If you do 100-4.08, you get 95.92 and since there's 4 video games, divide 95.92 by 4 and you get 23.98

Answer:

$23.98 or 2398 cents

Step-by-step explanation:

If the cashier gave $4.08 back, that means that he spent 100-4.08 on the 4 games.

$100 = 4 games + $4.08

4 games  = $95.92

$95.92/4 = $23.98
