Answer:
The answer is 21
Step-by-step explanation:
Simplify 2² to 4
Simplify 5² to 25
25=b²+4
b²=25-4
b²=21
and because you cant square root 21 the answer would be ±[tex]\sqrt{21}[/tex]

Solve the equation for x
25-3x=40
Answers
explanation:
you have to do inverse operation, so subtract 25 and -25 and then on the other side you do 40-25, which equals 15. After that you get -3x=15 and divide -3 on both sides.
What ever you do to one side you do to the other
First subtract 25 from itself and do the same to the total
25-3x=40 -3x=15
Next divide -3 from itself and the total ( keep in mind that when you multiply or divide a negative by a positive the answer will be a negative)
-3x=15 X=-5

3x+8(2x - 6) = 2 + 14x
Answers
Answer:
x=10
Step-by-step explanation:
Simplifying 3x + 8(2x + -6) = 2 + 14x
Reorder the terms: 3x + 8(-6 + 2x) = 2 + 14x 3x + (-6 * 8 + 2x * 8) = 2 + 14x 3x + (-48 + 16x) = 2 + 14x
Reorder the terms: -48 + 3x + 16x = 2 + 14x
Combine like terms: 3x + 16x = 19x -48 + 19x = 2 + 14x
Solving -48 + 19x = 2 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation. -48 + 19x + -14x = 2 + 14x + -14x Combine like terms: 19x + -14x = 5x -48 + 5x = 2 + 14x + -14x
Combine like terms: 14x + -14x = 0 -48 + 5x = 2 + 0 -48 + 5x = 2
Add '48' to each side of the equation. -48 + 48 + 5x = 2 + 48
Combine like terms: -48 + 48 = 0 0 + 5x = 2 + 48 5x = 2 + 48
Combine like terms: 2 + 48 = 50 5x = 50
Divide each side by '5'. x = 10
Simplifying x = 10

Answers
Answer:
Benito's line has a slope of three
Step-by-step explanation:
Slope can be determined by the rate of change. Because Benito's first point is 0,1 that means that x = 0 and y = -1. Benito's second point is 1,2 which means that x = 1 and y = 2. To determine the slope, you need to look at the change of y. We can see that y=-1 in the first point, and y=2 in the second point. This is an increase of three, which means that Benito's line has a slope of three.
Answer: Benito:On a coordinate plane, a line goes through points
(0, negative 1) and (1, 2).

From the information given, we can make this equation:
[tex]\frac{0.15}{60.00} =\frac{x}{250,000}[/tex]
Now all we need to do to find the answer is to solve for x.
-------------------------------------
Cross Multiplication:
[tex]\frac{0.15}{60.00} =\frac{x}{250,000}[/tex]
0.15*250,000=60x
37,500=60x

Answer:
[tex]m=8x-5-4\Delta x[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=4x^2-5x-1[/tex]
And we want to use the difference quotient:
[tex]m=\frac{f(x+\Delta x)-f(x)}{\Delta x}[/tex]
To find the slope function.
So, let's substitute [tex]x+\Delta x[/tex] for our function. This yields:
[tex]m=\frac{(4(x+\Delta x)^2-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]
Let's square. Use the perfect square trinomial pattern. This yields:
[tex]m=\frac{(4(x^2+2x\Delta x-\Delta x^2)-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]
Distribute:
[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)-(4x^2-5x-1)}{\Delta x}[/tex]
Distribute the right:
[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)+(-4x^2+5x+1)}{\Delta x}[/tex]
Combine like terms:
[tex]m=\frac{(4x^2-4x^2)+(-5x+5x)+(1-1)+(8x\Delta x-4\Delta x^2-5\Delta x)}{\Delta x}[/tex]
The first three terms will cancel. This leaves us with:
[tex]m=\frac{8x\Delta x-4\Delta x^2-5\Delta x}{\Delta x}[/tex]
We can factor out a Δx from the numerator:
[tex]m=\frac{\Delta x(8x-4\Delta x-5)}{\Delta x}[/tex]
The Δx will cancel. So, our slope function is:
[tex]m=8x-5-4\Delta x[/tex]
And we're done!

Which of the following is the solution to the inequality : -5x - 10 -6

Answers
Answer:
Your question might have an error :( All inequality equations have to have a inequality symbol somewhere in the equation. Yours dont have one but no worries. I'll see what I can do.
Based on your equation, that is not a inequality, so therefore your answer would have been: (-5x-16)
Step-by-step explanation:
If your equation was:
(-5x-10<-6) your answer would have been: x>-4/5
(-5x-10>-6) your answer would have been: x<-4/5
(-5x>-10-6) your answer would have been: x<16/5
(-5x<10-6) your answer would have been: x>-4/5
Those are all the possible outcomes of that equation :)
