Answer:
D. x=2, -2
Step-by-step explanation:
I think you're asking for the correct answer to the problem because all of the values for x won't work for the equation.
So all we have to do is simplify the equation to isolate x.
[tex]2x^2-8=0[/tex] (original problem)
[tex]2x^2=8[/tex] (add 8 to both sides)
[tex]x^2=4[/tex] (divide both sides by 2)
[tex]x=2, x=-2[/tex] (find the square root of both sides)
Note that x = ±2 and note just 2 because both [tex]2^2[/tex] and [tex](-2)^2[/tex] [tex]=4[/tex].
Hope this helped :D

Samantha made goodie bags for Valentines day. They were filled with choclates and candy.The cost of the chochlate was $2.50 per pound and the cost of the candy was $3.oo per pound. Samantha bought 15 pounds of choclate and candy for a total of 40 dollars. How much did Samantha buy
Answer:
We bought 10 Pounds of Chocolate, and 5 Pounds of Candy.
Step-by-step explanation:
Hey!
==================================================================
Let's make a chart!
Lbs Price Cost
Chocolate | x | 2.50 | 2.50x
Candy | 15-x | 3.00 | 3.00(15-x)
Equation:
2.50x + 3.00(15-x) = 40
--------------------------------------------------------------------------------------------------------------
⇒ 2.50x + 3.00(15-x) = 40
-Distribute 3 over 15-x
⇒ 2.50x + 45 - 3x =40
-Combine Like Terms
⇒ -0.5x + 45 = 40
-Subtract 45 from both sides.
⇒ -0.5x + 45 = 40
-45 -45
--------------------------
⇒ -0.5x = -5
-Divide by -0.5 on both sides
⇒ -0.5x/-0.5 = -5/-0.5
⇒ x = 10
That means we bought 10 Pounds of Chocolate.
---------------------------------------------------------------------------------------------------------------Since Candy was 15-x, we can Substitute 10 as x, and Solve:
⇒ 15 - 10
⇒ 5
That means we bought 5 Pounds of Candy.
--------------------------------------------------------------------------------------------------------------
We bought 10 Pounds of Chocolate, and 5 Pounds of Candy.

the sum of a number x and 7 is 35
An expression is defined as a set of numbers, variables, and mathematical operations. The value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given the statement that the sum of a number x and 7 is 35. Therefore, the given statement "the sum of a number x and 7 is 35" in the form of an expression can be written as,
x + 7 = 35
Subtract 7 from both the sides of the equation,
x +7 - 7 = 35 - 7
x = 28
Hence, the value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.

The table of ordered pairs (x, y) gives an exponential function.
Write an equation for the function.
y
- 1
6
0
12
1
24
2
48
Answer:
f(x) = 12*(2)^x
Step-by-step explanation:
A generic exponential equation is written as:
f(x) = A*(r)^x
And we also know that this equation passes through:
(-1, 6)
(0, 12)
(1, 24)
(2, 48)
For the second point, (0, 12) we know that when f(0) = 12
Then:
f(0) = 12 = A*(r)^0
And for every real number different than zero, a^0 = 1
Then:
f(0) = A*1 = A = 12
Then the equation is:
f(x) = 12*(r)^x
Now we can use one of the other points, like (1, 24)
Then f(1) = 24
We can solve:
f(1) = 24 = 12*(r)^1 = 12*r
24/12 = r
2 = r
Then the equation is f(x) = 12*(2)^x
Now we need to check if this function also passes through the points (-1, 6) and (2, 24):
f(-1) = 12*(2)^-1 = 12/2 = 6
f(2) = 12*(2)^2 = 12*4 = 48
Nice.
So we can see that the function is f(x) = 12*(2)^x

Examine the diagram. A triangle has angles A, 15 degrees, 80 degrees. The exterior angle to angle A is B. What is the sum of the remote interior angles? ° What is the measure of ∠A? m∠A = ° What is the measure of ∠B? m∠B = °
Answer:
m<A = 30degrees
m<B = 70degrees
Step-by-step explanation:
Find the diagram attached
From the diagram;
m<A + 150 = 180
m<A = 180 - 150
m<A = 30degrees
Also since the sum of angles in a triangle is 180degrees, hence;
m<B+m<A + 80 = 180
m<B+30+80 = 180
m<B+110 = 180
m<B = 180 - 110
m<B = 70degrees

Write an expression that represents the
perimeter of this picture frame.
Answer:
6x+2
Step-by-step explanation:
The perimeter is all of the sides added together.
We know that in a rectangle, sides that are parallel to each other are the same.
So, to find the expression that represents the perimeter, you have to multiply 2x+1 by 2 and x by 2 and add both of those together.
(2*(2x+1))+(2*(x))
(4x+2)+(2x)
4x+2+2x
