Answer:
y = [tex]\frac{1}{2}[/tex] x - 5
Step-by-step explanation:
Given f(0) = - 5 and f(4) = - 3 , then we have the coordinate points
(0, - 5) and (4, - 3)
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, - 5) and (x₂, y₂ ) = (4, - 3)
m = [tex]\frac{-3+5}{4-0}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]
The line crosses the y- axis at (0, - 5) ⇒ c = - 5
y = f(x) = [tex]\frac{1}{2}[/tex] x - 5 ← equation of line
A tree initially measured 18 feet tall. Over the next 312 years, it grew to a final height of 3512 feet. During those 312 years, what was the average yearly growth rate of the height of the tree?
Answer:
Average growth= 11.20 feet
Step-by-step explanation:
First, we need to calculate the total growth during those 312 years:
Total growth= 3,512 - 18
Total growth= 3,494 feet
Now, the average growth:
Average growth= total growth / number of years
Average growth= 3,494 / 312
Average growth= 11.20 feet
Calcula el numero de vueltas ,por minuto que, da la polea pequeña mienta la grande da 40 vueltas . Sabiendo que cada polea gira de manera que el radio y el numero de vueltas son inversamente proporcionales
Esta pregunta esta incompleta
Pregunta completa
Calcula el número de vueltas por minuto que hace la polea pequeña mientras que la grande hace 40 vueltas. Sabiendo que cada polea gira de manera que el radio y el número de vueltas son inversamente proporcionales.
El radio de la polea pequeña = 3 cm.
El radio de la polea grande = 9 cm
Answer:
120 vueltas por minuto
Step-by-step explanation:
El radio y el número de vueltas son inversamente proporcionales.
Por lo tanto
R = Radio
T = El número de vueltas por minuto
R ∝ 1 / T
R = k / T
Donde k es constante de proporcionalidad
Polea grande
R = 9 cm
T = 40 vueltas
9 = k / 40
k = 9 × 40
k = 360
Debemos encontrar el número de vueltas para la polea pequeña, por lo tanto,
R = k / T
k = 360, R = 3 cm
3 = 360 / T
3 × T = 360
T = 360/3
T = 120 vueltas
El número de vueltas de la polea pequeña = 120 vueltas por minuto

Cisco collected 53 pieces of candy on Halloween. He put away 4 dozen pieces to save for later and ate the rest. What percentage of his candies did Cisco put away for later?
he put away 91% of the candy for later because 100 divided by 53 is 1.89 and 1.89 multiplied by 48 equals 90.72 which rounds up to 91. hope you get a good grade!
Estimate. Then divide. 54184 divided by 26
Answer:
1,923.076923076923
Step-by-step explanation:
54,184 (look to the right; the number is lower than five so round down)
50,000/26=1,923.076923076923 (or 1923)

Determine the coordinates of the point shown
•(1.5 , - 2.5)
•(-2.5 , - 1.5)
•(-5, 3)
•(-2, 1)
Answer:
There the coordinates of the point are:
(x, y) = (-2.5, 1.5)
Therefore, option 'b' is true.
Step-by-step explanation:
From the coordinate plane, it is clear that the point is located in the 2nd quadrant.
We know that the second quadrant has negative x values and positive y values.
2nd quadrant → (-, +)
The point is clearly located at the location at x=-2.5 and y=1.5
There the coordinates of the point are:
(x, y) = (-2.5, 1.5)
Therefore, option 'b' is true.

Match each equation with a value of x that satisfies it.
Answer:
2, - 3, 18
Step-by-step explanation:
1). [tex]\sqrt[3]{1-x}[/tex] = - 1
( [tex]\sqrt[3]{1-x}[/tex] )³ = ( - 1)³
1 - x = - 1 ⇒ x = 2
2). [tex]\sqrt{x^2 +7}[/tex] = 4
( [tex]\sqrt{x^2 +7}[/tex] )² = 4²
x² + 7 = 16 ⇒ x = ± 3 ; x = - 3
3). [tex](x-2)^{\frac{1}{4} }[/tex] = 2
[tex][(x-2)^{\frac{1}{4} }] ^{4}[/tex] = [tex]2^{4}[/tex]
x - 2 = 16
x = 18
an elevator starts at the 6th floor it goes up 7/4 plus and then it goes down 10 floors. a second elevator starts on the 20th floor. it goes down five floors three times, and then it goes up 12 floors. which elevator ends up on a higher floor?
Answer:
Elevator 2
Step-by-step explanation:
Well let's make this simply by focusing on elevator number 1
it is on the 6th floor so we represent that as
6
Now it goes up 7/4 which is also the same as 1 3/4
the equation looks like this:
6+1 3/4
Add them together:
7 3/4
Now it goes down 10 meaning it is -10 add that to the equation:
7 3/4 - 10
Which is -2 1/4
Elevator number 1 is at floor number -2 1/4
Now for Elevator number 2
It is on the 20th floor which will make the equation looks like this:
20
Now it goes down five floors three times which can be represented like this:
20-5(3)
Simplify (Multiplication goes first according to the Order of Operations)
20-15= 5
Now it is 5 but it goes up 12 floors so the equation looks like this:
5+12
Simplify:
17
Now you could tell that elevator 2 ends up on a higher floor
Hope this helps!
IM IN NEED OF HELP .!!Antonio is at Best Buy and all TV's are 30% off. He finds a 75" OLED that he
wants, the price is $1500. What is the discount amount and how much did he
pay for the TV? Write and equation
Answer:
$450. The amount Antonio bought the tv for was $450.
Step-by-step explanation:
If all the tv's are 30%, multiple 30 by the price of the tv he wants, giving you 45000. Then, divide by 100 because a percent is out of a hundred, giving you $450
Formula:
(30x1500)/100
Simplify the following.

Pls do 2 answers for good measures (and brainliest)
Answer:
-5
Step-by-step explanation:
-2x+7>17
-2x>17-7
-2x>10
Divide both sides by -2
-2x<10
-2 -2
x<-5
Note:when dividing with a negative the signs changes
Answer:
Step-by-step explanation:
- 2x + 7 > 17
- 2x > 17 - 7
- 2x > 10
x < 10 ÷ ( - 2 )
x < - 5
x ∈ ( - ∞ , - 5 )
