what is the solution to the equation -3a +5=a-3(2a+1)
Answer:
the answer is a = -4
Step-by-step explanation:
pls mark brainliest
Answer:
a = -4
Step-by-step explanation:
To find a, we need to get the variable on one side of the equation. So first we distribute.
-3a+5=a-6a-3 Now we subtract 5 from both sides and add the a to the -6a
-3a=-5a-8 Now we add 5a to both sides
2a=-8 And lastly divide both sides by 2
a= - 4

Step-by-step explanation:
Answer:
48%
Step-by-step explanation:
So, we have to find what percentage is 12 out of the whole thing so:
We add the boys and the girls together to get the whole thing:
12 + 13 = 25
Then we turn it into a fraction:
12/25 = 48/100

Solve each system of equations algebraically
y=x+2
y=-3x
Answer:
Your answer is: (-1/2, 3/2)
Step-by-step explanation:
y = x + 2
y = -3x
Use substitution by plugging the second equation into the first.
-3x = x +2
Subtract x from both sides to combine the variables.
-4x = 2
Divide both sides by -4 to isolate the variable x.
x = 2/-4
Simplify.
x = -1/2
Plug x into one of the equations to find y.
y = (-1/2) + 2
y = 3/2
Plug x into the other equation to confirm your answer.
y = -3(-1/2)
y = 3/2
Your answer is: (-1/2, 3/2)

\/~~32
\/~~-32
\/~~10
\/~~130
Answer:
D) √130
The distance of the given points
AB = √130
Step-by-step explanation:
Explanation:-
Given points are A(-3,6) and B( 4,-3)
The distance formula
AB = [tex]\sqrt{x_{2}-x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]
AB = [tex]\sqrt{(4-(-3))^{2} +(-3-6)^{2}[/tex]
AB = [tex]\sqrt{(7)^{2} +(-9)^{2} }[/tex]
AB = [tex]\sqrt{49+81}[/tex]
AB = √130
may someone help me ASAP? I am solving polynomial equations and I don't know how to do it, here is the equation... x^4+11x^2=3x^2+128
Answer:
[tex]x=2\sqrt{2}[/tex], [tex]x=-2\sqrt{2}[/tex], [tex]x=4i[/tex], [tex]x=-4i[/tex]
Step-by-step explanation:
[tex]x^4+11x^2=3x^2+128[/tex]
First, we subtract 128 from both sides:
[tex]x^4+11x^2-128=3x^2[/tex]
Then, we subtract [tex]3x^2[/tex] from both sides:
[tex]x^4+8x^2-128=0[/tex]
Rewrite the equation:
[tex]u^2+8u-128=0[/tex]
Insert and solve:
[tex]u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i[/tex]

The legs of a right triangle measure 10 feet and 24 feet. What is the length of the hypotenuse, in
feet?
A. 27
B. 26
C. 34
D. 71,644
E. 48
Answer:26
Step-by-step explanation:
a squared+b squared= the hypotenuse squared
Input
10 squared+24 squared=the hypotenuse squared
100+576=676 squared
Now we need to find the square route of 676 because this is the hypotenuse squared, and we need to find the hypotenuse. And the square route of 676 is 26.

MONEY Claudio went for a walk. While he was walking, $1.35 fell out of his pocket. When he returned home, he counted his money and had $2.55 left. Write and solve an equation to find how much money was in Claudio’s pocket when he started his walk.
Answer:
3.9 that's how much he had
Answer:
He had $3.90 at the start of his walk.
Step-by-step explanation:
To find out how much money he had before his walk, you would take 2.55 + 1.35 and that you give you 3.9. But since we are dealing with money, you need to have the 0 at the end. So he started with $3.90 when he started his walk.

What is the value of x? Enter your answer in the box.
In this cube each small square has a side length 1 unit what is the surface area of this cube
==============================================================
Work Shown:
x = side length = 1 unit
SA = surface area of cube
SA = 6x^2
SA = 6*1^2
SA = 6*1
SA = 6
The surface area of the cube is 6 square units.
-------------------------
Side note:
In general, each face is x*x = x^2 units in area, and there are 6 of those faces. This is why the general surface area is 6x^2. In this case, each face is 1 square unit, so all 6 faces lead to a total of 6 square units.

image D(0.5, R)(1, 3), where R(−3, 5)
is the center of dilation?
A. (0.5,1.5) B. (-1.5,2.5) C. (3,2) D. (-1,4)
Answer:
d.(-1,4)
Step-by-step explanation:
Option D is correct, the coordinates of the image D are (-1, 4)
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To find the coordinates of the image D, we need to apply the dilation transformation centered at R(-3, 5). Let the scale factor be k.
The x-coordinate of D will be shifted k times the distance between 1 and -3, which is 4 units, from the x-coordinate of R, which is -3. So we have:
0.5 = -3 + k(4)
Solving for k, we get:
k = 1.375
Similarly, the y-coordinate of D will be shifted k times the distance between 3 and 5, which is 2 units, from the y-coordinate of R, which is 5. So we have
R: (x, y) = (-3, 5)
D: (x, y) = (-3 + 1.375(1 - (-3)), 5 + 1.375(3 - 5))
D: (x, y) = (-1, 4)
Therefore, the coordinates of the image D are (-1, 4), which is option D.

Dylan and Beatrice are working with the same function. Dylan input −8 into the function and got an output of 8.
Part A:
Based on this information, which statement is correct?
If Beatrice inputs −8 into the function, she must get an output of −8.
If Beatrice inputs −8 into the function, she must get an output of 8.
If Beatrice inputs 8 into the function, she must get an output of −8.
If Beatrice inputs 8 into the function, she must get an output of 8.
Part B
Which of the following points could the graph of the function possibly include? Select ALL that apply.
(−8,4)
(−4,8)
(4,−8)
(8,−4)
Answer:
Part A: If Beatrice inputs −8 into the function, she must get an output of 8.
Part B: (−4,8) , (4,−8) , (8,−4)
Step-by-step explanation:
Part A:
We know that a function is a relation that maps elements from one set (The domain, the set of the inputs) into elements from another set (the range, the set of the outputs)
Such that each input can be mapped into only one output.
Then if we know that our function maps the input -8 into the output 8.
Always that we use this function with the input -8. we will have the same output, 8.
Then we can conclude that the correct option to the first part is:
"If Beatrice inputs −8 into the function, she must get an output of 8. "
Part B:
Remember, -8 is mapped into 8, then the point (−8,4) (this says "-8 is mapped into 4) can never be on the graph of the function.
But the points:
(−4,8) , (4,−8) , (8,−4)
Could be on the graph of the function.
Answer:
correct A:-8,8
B: -4,8
