Answer:

y=2x+-4

Step-by-step explanation:

Answer:

The equation in slope intercept form (y = mx + b) is y = 2x - 4

m = the slope

b = the y intercept

The line cross the y-axis at -4 so the y-intercept (b) is -4.

You can use the slope formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.

[tex]\frac{0--4}{2-0}[/tex] = [tex]\frac{4}{2}[/tex] = 2

So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4

Answer:

32

Step-by-step explanation:

Let there be n number of steps on the ladder.

First, the firefighter climbed up to the middle of a ladder. so to reach the middle of the ladder he must have climbed [tex]\frac n 2[/tex] steps.

Then, after climbed 10 more steps, the total number of stairs from the ground he climbed [tex]= \frac n 2 +10[/tex].

Then, he came back down 14 steps, so the total number of stairs from the ground he climbed [tex]= \frac n 2 +10 -14=\frac n 2 -4[/tex].

Remaining steps [tex]= n - \left(\frac n 2 -4 \right)=\frac n 2 +4[/tex]

Given that he climbed 20 steps all the way to the top of the ladder which is equal to the remaining steps. So,

[tex]\frac n 2 +4 = 20[/tex]

[tex]\Rightarrow \frac n 2 = 20-4=16[/tex]

[tex]\Rightarrow n = 16 \times 2 = 32.[/tex]

Hence, there are 32 steps on the ladder.

Answer:

-11 and -1

Step-by-step explanation:

if you multiply -1 and -11, hte negatives will cancel out and it will be positive 11

if you add -11 and -1 the answer will be -12

The two numbers whose multiplication will give 11 and the add will be -12 are -1 and -11.

A quadratic equation is an algebraic expression whose power is raised to the second degree.

Mathematically, it can be expressed as:

ax² + bx + c = 0

For more examples, we can have x² -12x + 11 = 0

The way this is solved is that we are going to look for two numbers, in which:

Therefore, the two numbers are -1 and -11

SO, our quadratic equation can be re-written as:

x² - 1x - 11x  + 11 = 0

x(x - 1) -11(x - 1) = 0

(x - 11 ) (x - 1) = 0

Answer: Yes. This is because his fifth attempt was 52.47 seconds

Step-by-step explanation:

From the question, we are informed that Swimmers best time in event is 53.87 seconds and that on average, his best time decreases by 0.28 seconds each of the next five times he swims the event.

The time for the fifth time he swim will be:

= 53.87 - 5(0.28)

= 53.87 - 1.4

= 52.47 seconds

This means that he accomplish his goal of swimming the event in less than 52.5 seconds.

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.

Answer:

300persons

Step-by-step explanation:

First we need to find the total surface area of the room expressed as;

Total surface area = 2(LW+LH+WH)

L is the length = 30ft

W is the width = 15ft

H I the height = 10ft

Substitute

TSA = 2{(30(15)+30(10)+15(10)}

TSA = 2(450+300+150)

TSA = 2(900)

TSA = 1800ft²

Since an average person uses 6 square feet of area, the total numwr of people that can stand up the room is expressed as;

Total people = TSA/average area per person

Total person =1800/6

Total person = 300persons

Hence 300persos can stand up the room

Answer: F divide 168 by 28 and divide 108 by the answer

Step-by-step explanation:

From the question, we are informed that an astronaut weighs 168 lbs on earth and 28 lbs on the moon. We are further told that Kristine weighs 108 lbs on earth.

To find out the weight of Kristine on the moon, we divide 168 by 28 and divide 108 by the answer. This will be:

= 168/28 = 6

We then divide 108 by 6. This will be:

= 108/6

= 18

Kristine weight on the moon is 18lbs

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V

Pool K slope & intercept  = 30 & 5 , Pool M slope & intercept = 10 & 10

Step-by-step explanation:

Total cost  [Pool] = Fixed (membership) cost + Variable cost (per visit)

Intercept is part at which equation line intersects x or y axis. In pools case, it is  fixed (membership) cost. Slope is change in y due to change in x. In pools case, it is variable cost (per visit)

Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V

where V = number of visits.

Pool K slope & intercept  = 30 & 5 , Pool M slope & intercept = 10 & 10

what you just said is racist in itself, it is also wrong. If you put 1 million white people in a room with 1 million black people statistics prove there will be more racist people of color. The reason why there are more white racist people world wide is because there are more white people than any other race alive to this day, so if you want to be smart about it you would know how to make it even. It's also 30% as well compared to 39% of racist black people.
