Step-by-step explanation:
Answer: A = y=-3x+1
Step-by-step explanation: If you plug in -2 and use 7 from Y
7 = -3(-2) +1
7= 6+1
7 = 7
Hope this helps pls mark me brainliest. :)
Explain why square root of -2 is equal to i square root 2
Answer:
Because square roots aren't really negative. if you multiplied square roots by themselves they can equal positive and negative

Solve the system using elimination. 3 x plus 3 y equals 27. x minus 3 y equals negative 11.
Answer:
- 5/4
Step-by-step explanation:
Answer:
x=4 and y=5 commonly notated as (4,5)
Step-by-step explanation:
The equations
Equation 1: 3x+3y=27
Equation 2: x-3y= -11
The second equation looks like it will be the easiest to rearrange.
x-3y = -11
add 3y to each side to get
x = 3y-11
Substitute that in for x in equation 1 so
3x+3y=27
turns into
3(3y-11) +3y =27
multiply out to get
9y-33+3y =27
Condense variables
12y-33=27
add 33 to each side
12y= 60
Divide by 12
y = 5
Plug into one of the original equations (I will be doing both to show it doesn't matter what equation you use, but you only need to use one equation, I personally think it is easier to plug into the second equation)
Equation 1: 3x+3y=27
Plug in what we got for y
3x+3(5)=27
multiply
3x+15=27
subtract 15 from each side
3x=12
divide by 3
x=4
Equation 2: x-3y = -11
Plug in what we got for y
x-3(5) =-11
Multiply
x-15= -11
Add 15 to each side
x=4

We have a dilemma here, there is a variable and constant numbers in this equation. No fear, this is when like terms comes into play, where you can only combine two numbers that have the same ending, whether it be variables, exponents, e.t.c.
Distribute :
4 + 16 - 12(1 + 2x)
4 + 16 - (12(1) + 12(2x))

A line with a slope of 3 passes through the point (2, 4). What is the y-intercept of the line?
Answer:
y-intercept = -2
Step-by-step explanation:
Use the point-slope form of a line to do this problem.
[tex]y - y_{1} = m(x - x_{1})[/tex]
y - 4 = 3(x - 2) Now change the equation to slope-intercept form
y - 4 = 3x -6
y = 3x - 2 So m = 3 b = y-intercept = -2
Evaluate the expression x
x(2 – 5y)²
when x= = -5 and y=-3.
[tex]\displaystyle -5(2-5(-3))^2=-5(17)^2=-1445[/tex]
U is the midpoint of TV. If TU = 6x and TV = 11x + 8, what is TV?
T
6x
V
11x + 8
Simplify your answer and write it as a proper fraction, mixed number, or integer.
Answer:
96
Step-by-step explanation:
U is the midpoint of TV, so mTU is half of mTV or mTV = 2 * mTU, so
mTV = 2 * mTU
11x + 8 = 2 (6x)
11x + 8 = 12x
8 = x
mTV = 11x + 8 = 11(8) + 8 = 88 + 8 = 96

A flagpole and a model flag pole have a scale factor of 1 in.= 4 ft. If the model pole measures 12 inches, how tall is the actual pole?
Answer:
[tex]48\ \text{feet}[/tex]
Step-by-step explanation:
[tex]1\ \text{inch}[/tex] of the model is [tex]4\ \text{feet}[/tex] of the actual pole.
Here, the pole which is present in the model measures [tex]12\ \text{inches}[/tex], so
[tex]12\ \text{inches}[/tex] of the model will be [tex](12\times 4)\ \text{feet}=48\ \text{feet}[/tex]
Hence, the actual pole will be [tex]\boldsymbol{48\ \text{feet}}[/tex] tall.

You are at Coney Island Amusement Park, and burgers
cost $5 and hot dogs cost $3. You and your friends
spend $45. This is modelled by the equation
5b + 3h= 45.
Is the solution (2, 5) a viable solution?
show your work to the left]
Answer: No, the ordered pair (2,5) is not a viable solution
===========================================================
Explanation:
(2,5) means that b = 2 and h = 5
I'm assuming each ordered pair is of the form (b,h) where b comes first, since b is before h in the alphabet.
So if b = 2 and h = 5, then we can replace each letter with those numbers to get the following:
5b + 3h = 45
5*2 + 3h = 45 ..... b replaced with 2
5*2 + 3*5 = 45 ..... h replaced with 5
10 + 15 = 45
25 = 45
We don't get the same number on both sides, so (b,h) = (2,5) is not a solution.
--------------
Put another way:
If b = 2 and h = 5, this means you bought 2 burgers and 5 hot dogs
1 burger = $5
2 burgers = 2*5 = $10
1 hot dog = $3
5 hot dogs = 5*3 = $15
total amount spent = $10 + $15 = $25
total amount spent = $25
This does not match up with the $45 total spent that we're given. So this is another way to see we don't have a solution.
Which set of ordered pairs represents y as a function of x?
{(1.9, 2), (0.9, 4), (1.9,7), (9,3)}
B
{(4,3), (0.25, 7). C 4), (0.75,6)
{(0,3), (8,14), (0, ), (8,18)
{(2, 2), (§, 2). C.;2), (, 2)
I need help please !
Answer:
yes
Step-by-step explanation:
because although some of the other are missing to be a function, it has to have an element of x and of y, it does not matter that some do not have it with one of y and one of x is enough
And if you are talking about relation it is also because they comply with the rules

Use rule that a straight line is 180 and a right angle is 90
Subject:Mathematics
Answer:
x=28°
Step-by-step explanation:
2x+3x-10+50=180
5x+40=180
5x=180-40
5x=140
x=140/5
x=28°
The angle measure of a triangle are shown in the diagram.
What is the value of x?
Answer :value of x is 28°Explanation :Given :∠A = 50°∠B = (2x)°∠C = (3x - 10)° To Find :Value of x = ?Solution :As, In a triangle measure of all three angles is always 180°.
[tex] \sf : \implies \angle A + \angle B + \angle C = 180\degree[/tex]
[tex] \sf : \implies 50\degree + (2x)\degree + (3x - 10)\degree = 180\degree[/tex]
[tex] \sf : \implies 50 + 2x + 3x - 10 = 180\degree[/tex]
[tex] \sf : \implies 40 + 5x = 180\degree[/tex]
[tex] \sf : \implies 5x = 180\degree - 40\degree[/tex]
[tex] \sf : \implies 5x = 140\degree[/tex]
[tex] \sf : \implies x = \cancel{\dfrac{140\degree}{5}}[/tex]
[tex] \sf : \implies x = 28\degree[/tex]
[tex] \large \underline{\boxed{\bf{x = 28\degree}}}[/tex]
Hence, value of x is 28°.
