What is the value of x? Enter your answer in the box.
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)

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 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

A class is made up of 12 boys and 13 girls. What percent of the class is boys?
Answer:
12/13 or 92.31%
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
So, 48% of the class is boys
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.
Find the indicated term of each sequence by repeatedly multiplying the first term by the common ratio. Enter your answer to 7 decimal places if necessary. Use a calculator. 12, −2.4, 0.48, ...; 7th term The 7th term of the sequence is
Answer:
The 7th term of the sequence is 0.000768
Step-by-step explanation:
As given, the sequence is : 12, -2.4 , 0.48, ....
The first term = 12
Second term = -2.4
Third term = 0.48
Common ratio = [tex]\frac{-2.4}{12} = \frac{0.48}{-2.4} = -0.2[/tex]
Fourth term = 0.48(-0.2) = -0.096
Fifth term = -0.096(-0.2) = 0.0192
Sixth term = 0.0192(-0.2) = -0.00384
Seventh term = -0.00384(-0.2) = 0.000768

The radius of a circular clock is 10.5 inches. Which measurement is the closet to the measurement of the circumference of the clock in inches?
Answer:
66 in approx
Step-by-step explanation:
Given data
Radius= 10.5 inches
The circumference is given as
C= 2πr
Substitute
C=2*3.142*10.5
C=65.982
Hence the Circumference is 66 in approx
What is the distance from A(-3, 6) to B(4, -3)?
\/~~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

16a^2b^3c^6/48ab^5c^6
Answer:
a/3b^2
Step-by-step explanation:
16a^2b^3c^6/48ab^5c^6
the c^6 cancel out, then simplify a^2 and a: 16a^2b^3/48ab^5 = 16ab^3/48b^5
Then divide 48 and 16 you get 3 16ab^3/48b^5 = ab^3/3b^5
And lastly, simplify b^3 and b^5 ab^3/3b^5 =
a/3b^2

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]

What is the slope of the line
represented by 5x – 7y = 9?
Answer:
5/7.
Step-by-step explanation:
Convert to slope-intercept form:
5x – 7y = 9
Subtract 5x from both sides:
-7y = -5x + 9
Divide through by -7:
y = (-5/-7) x + -9/7
y = 5/7 x - 9/7
The slope is 5/7.

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
Step-by-step explanation:
