-3a+2b=-3
solve for a
Answer:
a = (3 + 2b) / 3
Step-by-step explanation:
1) Move 2b to the right.
-3a + 2b = -3
-3a = -3 - 2b
2) Leave only a on the left.
a = (-3 - 2b) / (-3)
a = -(3 + 2b) / (-3)
a = (3 + 2b) / 3

Someone I need it asapppp
Answer: is II and III an option those are the ones that would be correct.
Step-by-step explanation:
You can only have one of each domain. For example you cannot have (0,0) and (0,1) since that won’t pass the vertical line test, you can have (0,0) and (4,0) as long as the domains are different, they can still have the same ranges.
Giovanni justifies whether the expression –4x – 8 is equivalent to Negative 2 (x + 1) minus 2 (x + 3) by letting x = 3 in both expressions. What is the value of each expression when x = 3?
Answer:
They are equivalent
Step-by-step explanation:
-4(3)= -12 -8 = -20
-2 (3+1)= -6-2 = -8
-2(3+3)= -6-6 = -12 -8+-12=-20
both equal -20.
Answer:
-20 -20

factor the expression below 25x^2+20x+4
Answer: (5x + 2)(5x+2)
Step-by-step explanation: I just did a quiz with the same question
The factor of the given expression are (5x + 2)(5x+2)
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We will recognize that the first (25x^2) and last (4) terms are perfect squares. The middle term is double the product of the roots of those squares is;
2(5x)(2) = 20x
Which means the given expression is a perfect square trinomial, and that it is the square of (5x+2).
25x^2 +20x +4
= (5x +2)^2
= (5x +2)(5x +2)
Here, we have a=5x, b=2.

Complete the point-slope equation of the line through (1,-1) and (5,2)
Answer:
y + 1 = [tex]\frac{3}{4}[/tex](x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (5, 2)
m = [tex]\frac{2+1}{5-1}[/tex] = [tex]\frac{3}{4}[/tex]
using (a, b) = (1, - 1 ), then
y - (- 1) = [tex]\frac{3}{4}[/tex](x - 1) , that is
y + 1 = [tex]\frac{3}{4}[/tex](x - 1)

What is the solution to 10(2x - 4) = 100x? Please do your best.
10(2x-4)=100x
20x-40=100x
-40=100x-20x
-40= 80x
-40/80x= -0.5
10(2x-4)=100x
20x-40=100x
20x=100x+40
20x-100x=40
-80x=40

The length of a rectangle is 5 less than twice it's width. The perimeter is 26 meters. Find the deminsion of rectangle.PLease show me step by step
Answer:
Width = 6 m and lenght = 7 m
Step-by-step explanation:
Let x be the width of the rectangle.
lenght = 2x - 5
Perimeter means the addition of all sides of the rectangle.
Thus, x + x + 2x - 5 + 2x - 5 = 26
2x + 2x + 2x = 26 + 10
6x = 36, x= 6
Therefore, width is 6 m and lenght is 2 (6) -5 == 7 m

Thirteen less than eight times a number is three more than four times the number.
What is the number?
Answer:
Step-by-step explanation:
Let the number = x
8x - 13 = 4x + 3 Add 13
8x = 4x + 3 + 13 Combine
8x = 4x + 16 Subtract 4x
8x - 4x = 16 Combine
4x = 16 Divide by 4
x = 16/4
x = 4

Look at △STU on this coordinate grid. Suppose that △S'T'U' is the result of a dilation of △STU with a scale factor of 2. What are the coordinates of point S'? *
Answer:
(4,2)
Step-by-step explanation:
THIS IS ASSUMING you are scaling it around 0,0
S is 2,1.
(x',y') = (2,1)
You want to find the coords with a scale factor of 2.
(x',y') = 2(2,1)
x',y' = 4,2

Answer:
1 foot
Step-by-step explanation:
The far above the water is the yellow mark is 1 foot.
Important information:A waterwheel has a radius of 4 feet, and the center of the wheel is 1 foot under the waterline. Calculation of feet:[tex]cos \frac{\pi}{3} = \frac{OB}{OA}\\\\ \frac{1}{2} = \frac{OB}{4}\\\\ OB = 2[/tex]

someone help me... please show work
Answer:
x=5
Step-by-step explanation:
Set the 2 equations equal to each other and solve for x.
11x-28=7x-8
add 28 to both sides (-8+28=20)
11x=7x+20
subtract 7x from both sides (11x-7x=4x)
4x=20
divide both sides by 4 to isolate x (20/4=5)

Antoine made $33,284 last year. He received a 4.5% annual raise. What will his new salary be for the coming year?
Answer:
$34,781.78
Step-by-step explanation:
the annual salary is $33,284 which is 100%and the raise is 4.5%which you add 100% .u add the 100% because it is a profit .then it becomes 104.5% .
the equation is: $33,284=100%
? =104.5%
Cross multiply then the equation is:
$33,284×104.5%/100%=34,781.78
03.01 MC) A surveyor randomly interviewed 65,439 people who live in Virginia to gather information on whether national healthcare is accomplishing its goals. Part A: What are the population and sample in this survey? (4 points) Part B: The survey found that 71% of females and 88% of males visited a family doctor at least once in the past year. Do you think these approximations of the sample are close to approximations of the entire population? Explain. (6 points)
Answer:
Part A: The population and the sample of the survey are;
The population = The entire population of the country
The sample = 65,439 people in the state of Virginia
Part B: Given that the survey was based on only one state and only one model of health care delivery, the approximations of the sample will not be close to the approximations of the entire population
Step-by-step explanation:
The given information are;
The number of people interviewed in the survey = 65,439 people
The location of the people surveyed = Virginia
The goal of the survey = The effectiveness of the national healthcare
The number of females that visited a family doctor at least once in the past year = 71%
The number of males that visited a family doctor at least once in the past year = 88%
Part A: The population and the sample of the survey are;
The population = The entire population of the country
The sample = 65,439 people in the state of Virginia
Part B: Given that the survey was based on only one state and only one model of health care delivery, the approximations of the sample will not be close to the approximations of the entire population.

You got to McDonald's and order some food for you and your friends.Your friends give you a list of what you need to order: 1 cheeseburger, 2 orders of fries, 3 cheeseburgers, and 3 orders of fries. How can you simplify this order so that way you don't have to read of the exact list they gave you.
Answer:
4 cheeseburgers and 5 fries.
Step-by-step explanation:
Here, the orders given are as follows:
1 cheeseburger,
2 orders of fries,
3 cheeseburgers, and
3 orders of fries
If we observe closely, it can be seen that there are orders of cheeseburgers 2 times and orders of fries also 2 times.
In order to simplify the given list, we must add the similar kind of orders together.
Therefore the given order list can be written as:
1 cheeseburger + 3 cheeseburgers, and
2 orders of fries + 3 orders of fries
OR
In other words:
4 cheeseburger, and 5 orders of fries
Therefore, the simplified order is:
4 cheeseburger, and 5 orders of fries
