Answer:
y = mx + b
y= 2x +3explanation:
[tex]m = \frac{y2 - y1}{x2 - x1} \\ \frac{5 - 3}{1 - 0} = m \\ m = 2[/tex]
Answer:
y = 2x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (2, 7) ← 2 points on the line
m = [tex]\frac{7-3}{2-0}[/tex] = [tex]\frac{4}{2}[/tex] = 2
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = 2x + 3 ← equation of line
1) A hot tub holds 500 gallons of water and drains at a rate of 10 gallons per minute. Type an equation that represents how many gallons are left in the tub after it has drained for x minutes.
2) After 16.5 min, how much water is left in the tub?
3) How long will it take the hot tub to be completely empty?
Answer:
Step-by-step explanation:
`) y=500-10x
y is how much water is left in the tub
the 500 is how many gallons of water is already in the tub
-10x is how much water is drained every minute
2) plug in 16.5
y=500-10*16.5
y=500-165
y=335
335 gallons left
3) make y 0 because that represents how many gallons are in the tub
0=500-10x
-500=-10x
/-10
x=50
50 minutes

1. Lirio is exerting a force of 89 N on a nice boulder in her swamp. The nice boulder is 68 kg. What is the acceleration of the nice boulder?
2. If Renae has a mass of 85 kg, and you exert a force of 45N on her, what would her acceleration be?
CAN I PLEASE GET HEPL ON THESE 2 I NEED TO KNOW THE EQUATIONS!!!
Answer:
Step-by-step explanation:
1.
F=ma
89=68a
a=89/69 units/s²
2.F=ma
45=85 a
a=45/85=9/17 units/s²
Problem 1
Answer: Approximately 1.3 m/s^2
---------------
Work Shown:
We'll use the formula F = m*a, which is from Newton's second law.
The force applied is F = 89 newtons. The mass of the boulder is m = 69 kilograms. This means,
F = ma
89 = 69*a
a = 89/69
a = 1.28985507246377
a = 1.3
I rounded to 2 sig figs because the other given values (89 and 69) are to 2 sig figs as well.
=================================================
Problem 2
Answer: Approximately 0.53 m/s^2
---------------
Work Shown:
We'll follow the same idea as problem 1
This time we are given F = 45 and m = 85
So,
F = ma
45 = 85*a
85a = 45
a = 45/85
a = 0.52941176470589
a = 0.53
The acceleration is roughly 0.53 m/s^2, which means that for every second, the speed is increasing by roughly 0.53 m/s.
There are 625 students in Weaver Junior High School. Jimmy surveyed the 30 students in his English class regarding their favorite subject. Twenty-four of the students responded that they liked history best. If his class is a representative sample of the entire school, how many students in the school could Jimmy predict would choose history as their favorite subject?
Answer:
I love you too luv uip basin MA unsa ka luv Amfing ara luv ha ayaw pod tawn ana man
The number of students in the school could Jimmy predict would choose history as their favorite subject is 500.
What is random sampling?In statistics, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. It is a method of choosing a sample at random.
Given that, there are 625 students in Weaver Junior High School.
24 of the 30 students surveyed liked history.
The students surveyed liked history
=24/30 ×100
= 0.8×100
= 80%
Now, 80% of 625 students
625 × 0.8 = 500
So, 500 of the total students like history
Therefore, the number of students in the school could Jimmy predict would choose history as their favorite subject is 500.

Find the missing side in the similar figures below
Answer:
a. 28.8
Step-by-step explanation:
Using the theorem of similarity, the following equation can be generated:
[tex] \frac{x}{12} = \frac{25 + 35}{25} [/tex]
Solve for x
[tex] \frac{x}{12} = \frac{60}{25} [/tex]
Cross multiply
[tex] x*25 = 60*12 [/tex]
[tex] 25x = 720 [/tex]
Divide both sides by 25
x = 28.8

g(n)=-4n-3; find g(10)
Answer:
g(10) = - 4+
Step-by-step explanation:
Given
g(n) = - 4n - 3
Now
g(10)= - 4 * 10 - 3
= -40 - 3
= -43
Hope it will help :)
Step-by-step explanation:
Hey there!
Given;
g(n) = -4n-3
And to find: g(10)
Simply replace "n" by "10" on every place where there is "n". So,
g(n) = -4n-3
~Replace by "10".
g(10) = -4*10-3
= -40-3
= -43
Therefore, g(10) = -43.
