Graph the following lines and write the equation in slope-intercept form.
Through the point (−8,1) with a slope of 3.
Answer:
y=mx+b
3=slope
1=y coordinate
-8=x coordinate
b=y intercept
Substitute m for 3
y=3x+b
Next, substitute the coordinate values
1=3(-8)+b
Solve
1=-24+b
+24 +24
25=b
Now substitute b and m for their respective values
y=3x+25

Jacob trims trees and mows lawns during the summer months he earns 50$ per lawn and 120$ per tree he wants to purchase a car for 4,500if Jacob plans to mow 45 lawns this summer how many trees must he trim to earn at least 4,500
Answer:
at least 19
Step-by-step explanation:
Let t represent the number of trees Jacob needs to trim. He wants ...
50(45) +120t ≥ 4500
120t ≥ 2250 . . . . . . . . . subtract 2250
t ≥ 18.75
Jacob must trim at least 19 trees to earn at least $4500.

Solve 4(3b + 2) – 5b = 43 for b. Question 4 options: A) b = 3 B) b = 5 C) b = –3 D) b = –5
Answer:
b = 5
Step-by-step explanation:
4 ( 3b + 2 ) - 5b = 43 Given
( 4 • 3b + 4 • 2 ) - 5b = 43 Distributive Property
12b + 8 - 5b = 43
12b - 5b + 8 = 43 Combine like terms
7b + 8 = 43
7b + 8 - 8 = 43 - 8 Subtraction Property of Equality
7b = 35
7b / 7 = 35 / 7 Division Property of Equality
b = 5

Someone help me solve this it's easy i just don't understand simple math
Answer:
The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.

Noya needs to determine the number of books that will fit into a box. If the box has a length of 18 inches and each book is StartFraction 2 Over 9 EndFraction of an inch thick, which expression can be used to determine the number of books that will fit into the box?
18 StartFraction 2 Over 9 EndFraction
18 times StartFraction 2 Over 9 EndFraction
StartFraction 2 Over 9 EndFraction divided by 18
StartFraction 9 Over 2 EndFraction divided by 18
Answer:
A. 18 divided by 2/9
Step-by-step explanation:
To determine the number of boos that will fit into a box that is 18 inches long, we divide the length of the box by the length of the books
18 inches divided by 2/9 inches per book

HELP PLSSS
Answer:
x>-8
Step-by-step explanation:
-9 <3x +15
-24 <3x
-8<x
Answer:
X<-1/5
Step-by-step explanation:
I dont really understand what you wrote but I’m assuming its -9<3x(15)
so -9<45x
Divide 45 on both sides to isolate the variable
-9/45<X
simplify
-1/5<X
Check:
-9<3(1)(15) (I used 1 cause it’s greater then -1/5 and it’s a easier number to work with)
-9<45✔️
Solve.
y/3 - 5 = 4
y =
[tex]\frac{y}{3} - 5 = 4\\\\\frac{y}{3} \cdot 3 - 5 \cdot 3 = 4 \cdot 3\\ y - 15 = 12\\y = 12 + 15\\y = 27[/tex]
Answer:
y = 27
Step-by-step explanation:
So we have to solve for y in the given equation.
[tex]\frac{y}{3}-5=4[/tex]
Add 5 to both sides.
[tex]\frac{y}{3}=9[/tex]
Multiply both sides of the equation by 3.
y = 27
So we have found that y = 27.

what is 2x=8a+2b; solving for x
Answer:
Step-by-step explanation:
Flip the equation 1) 8a + 2b = 2x
Subtract 2b from both sides 2)8a + 2b(-2b) = 2x + (-2b)
Divide by 8 on both sides 3) 8a/8 = -2b - 2x/8
4) a = 1/-4b + 1/4x
is 5.565656... a rational number
Answer:
Yes 5.565656 is a rational number
Step-by-step explanation:
How do we know?
Rational: Numbers that end and do not go on forever
Examples:
Decimals that end or repeat (in your case)
Fractions
Whole numbers
Square Roots
Yes, the number 5.565656... is a rational number.
We have,
A rational number is defined as any number that can be expressed as the quotient or ratio of two integers, where the denominator is not zero.
In the case of 5.565656..., it is a repeating decimal.
However, repeating decimals can always be expressed as a fraction.
Let's represent 5.565656... as x:
x = 5.565656...
Now, if we multiply both sides of the equation by 100 (to remove the repeating decimal), we get:
100x = 556.565656...
Subtracting the original equation from the above equation, we have:
100x - x = 556.565656... - 5.565656...
99x = 551
x = 551/99
The fraction 551/99 is a ratio of two integers, and it represents the value of 5.565656....
Therefore,
5.565656... is a rational number.
