Answer:
x=49
Step-by-step explanation:
you replace the unknown with a variable (x)
you subtract 7 three times, so it x-7-7-7=28 or x-21=28
you add 21 to both sides, then you get x=49
-3x + 2c =3 solve for x

Answer:
true because you combine like terms
Answer:
True.
Step-by-step explanation:
The two terms share the same variable (as well as the same amount of that variable), that being y. Combine the coefficients:

Answer:
5)y=2x 6)y=12x 7)y=3x-2 8)y=1/4x+2
Step-by-step explanation:
Look at the y-intercept first if crosses the origin then don't need to write anything. If it does you add it after the slope.
To find slope you can count how many units up or down it does and how many left or right.
Then write i as rise/run.

If f(x) = 3x + 2, then find the value of x such that f(x) = -4.
Answer:
See Below
Step-by-step explanation:
Solve by substituting
-4 = 3x + 2
-2 -2
-6 = 3x
3x/3 = -6/3
x = -2
Answer:
x = -2
Step-by-step explanation:
So we are given the function f(x) = 3x + 2 and we are asked to find the value of x that makes f(x) = -4. To do this, we can replace f(x) with -4 in the given function and solve for x.
-4 = 3x + 2
Swap sides.
3x + 2 = -4
Subtract 2 from both sides.
3x = -6
Divide both sides by 3.
x = -2
So we have found that x = -2 when f(x) = -4. This means that when x = -2, f(x) = -4.

Answer:
1) 110*, 2) 84*, 3) 80*
Step-by-step explanation:
These are intersected parallel lines (with only 1 intersecting line), so having missing angles in the questions 1 and 2 opposite from the shown angle is giving the answer away. However, on answer 3, it is on the same side, so for that angle you will need to subtract the angle of the intersecting line by 100* to get 80*. Check by adding the two. 100* + 80* = 180*. Hope this helps.

y varies directly with x if y= 4 when x= -1 what is the value of x when y = 6
Answer:x=-(3/2)
Step-by-step explanation:
y=kx (y=4,x=-1)
4=k(-1)
k=-4
y=6 x=?
6=kx
We know k = -4
6=-4x
x=-(3/2)
How are the slope formula and finding slope using "rise over run" related?
Answer:
they are the same thing
Step-by-step explanation:
Answer:
They are practically the same thing but if you want to get technical then they are related because A slope a measure of steepness. A line with a large slope, such as 25, is very steep. A line with a small slope, such as 1 /10 is very flat. So this means it will rise over run if that makes sense.

Suppose that 24 inches of wire costs 96 cents.
At the same rate, how much (in cents) will 47 inches of wire cost?
Answer:
Step-by-step explanation:
24inches = 96 cents
To find the cost of 1 inch, divide 96 cents by 24.
1 inch = 96/24 = 4 cents
Then to find the cost of 47 inches, multiply by 4.
47 inches = 47 x 4 = 188 cents.

Answer:
around 28% of americans are obese
Step-by-step explanation:
The relative frequency of obesity according to this poll is 28 percent.
How to find the relative frequency?Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).
Suppose you've to calculate the joint relative frequency of a certain category out of the given big category.
Then its the ratio of the frequency of that certain category to the total frequency of that big category.
Given According to a recent poll 4060 out of 14500 people in the United States were classified as obese based on their body mass index .
Therefore, the relative frequency of obesity according to this poll is 28 percent.

1. Solve the system of equations by substitution:
y = x - 2
4x – 3y = 11
Answer:
x = 5
y = 3
Step-by-step explanation:
y = x - 2
4x - 3y = 11
substitute y in the second equation with x - 2
4x - 3(x - 2) = 11
open the parenthesis
4x - 3x + 6 = 11
x + 6 = 11
subtract 6 from both sides of the equation
x + 6 - 6 = 11 - 6
x = 5
now substitute x for 5 in the original equation.
y = x - 2
y = 5 - 2
y = 3

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3). What is the coordinates of the image if the parallelogram is dilated with a scale factor of -1/3
Answer: [tex](\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .[/tex]
Step-by-step explanation:
Transformation rule for dilation:
[tex](x,y)\to(kx,ky)[/tex] , where k = scale factor
Given : Scale factor = [tex]-\dfrac13[/tex]
Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3)
Vertices after dilation:
[tex](-1,6)\to(-1\times\dfrac{-1}{3},6\times\dfrac{-1}{3})=(\dfrac13,-2)[/tex]
[tex](0,9)\times(0\times-\dfrac13,9\times-\dfrac13)=(0,-3)[/tex]
[tex](6,-3)\to(6\times-\dfrac13,\ -3\times-\dfrac13)=(-2,1)[/tex]
[tex](3,-3)\to (3\times-\dfrac13,\ -3\times-\dfrac13)=(-1,1)[/tex]
Hence, the coordinates of the image if the parallelogram = [tex](\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .[/tex]
