Write y+4=−1/2(x−2) in slope intercept form .
Answers
Answer:
y = - [tex]\frac{1}{2}[/tex] x - 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 )
Given
y + 4 = - [tex]\frac{1}{2}[/tex] (x - 2) ← distribute
y + 4 = - [tex]\frac{1}{2}[/tex] x + 1 ( subtract 4 from both sides )
y = - [tex]\frac{1}{2}[/tex] x - 3 ← in slope- intercept form

A ball is thrown straight up from the top of a building that is 280 feet high with an initial velocity of 48 ft/s. The height of the object can be modeled by the equation s(t)=−16t2+48t+280.
In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation. Then, determine the time.
Answers
Answer:
i hope it helpful
thank you
Answer:
Answer in interval notation is (3, 5.94].
Step-by-step explanation:
First find the time that the ball is level with the top of the building on its descent. You can do this by solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds .
Then when the ball reaches the ground the time t is obtained by solving 0 = -16t^2 + 48t + 280 This gives t = 5.94
seconds.
Answer in interval notation is (3, 5.94].

Ezra has two weeks to sell popcorn to earn money for camp. For each unit of popcorn that he sells, Ezra will earn $5. He wants to earn at least $250
. During the first week he earned $105.
How many units of popcorn must Ezra sell in the second week to earn at least $250 in the two weeks combined?
Answers
in the first week he sold 21 units of popcorn
he needs to sell 50 units in all
so 50-21= 29
he needs to sell 29 more units of popcorn
The number of units that needs to be sold to earn at least $250 is 20.
What is inequality?
It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
The minimum amount that needs to be earned = $250
One unit cost = $5
The amount earned in the first week = $105
Number of units = x
The number of units to sell in the second week.
150 + 5x ≥ 250
5x ≥ 250 -150
5x ≥ 100
x ≥ 20
Thus,
20 units need to be sold to earn at least $250.

Answer:
x = 13

Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
-2x + 6 = -20
Step 2: Solve for x
Subtract 6 on both sides: -2x = -26Divide -2 on both sides: x = 13Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -2(13) + 6 = -20Multiply: -26 + 6 = -20Add: -20 = -20Here we see that -20 does indeed equal -20.
∴ x = 13 is the solution to the equation.
If f(x)=3x^5+2x^4+5, then what is the remainder when f(x) is divided by x−1?
Answers
Answer:
The remainder is 10
Step-by-step explanation:
The find the remainder when f(x) divided by g(x), find the value of x when g(x) = 0, then substitute it in f to find the value of the remainder
∵ f(x) = 3[tex]x^{5}[/tex] + 2[tex]x^{4}[/tex] + 5
∵ f(x) is divided by x - 1
∴ g(x) = x - 1
→ Equate g(x) by 0 to find x
∵ g(x) = 0
∴ x - 1 = 0
→ Add 1 to both sides
∵ x - 1 + 1 = 0 + 1
∴ x = 1
→ Substitute x in f by 1
∵ f(1) = 3[tex](1)^{5}[/tex] + 2[tex](1)^{4}[/tex] + 5
∴ f(1) = 3(1) + 2(1) + 5
∴ f(1) = 3 + 2 + 5
∴ f(1) = 10
∵ The remainder is the value of f(1)
∴ The remainder is 10
