Answer:
f(-4)=-2(-4)²+8(-4)-10=-2×16-32-10=-74
Step-by-step explanation:
Given
f(x) = - 2x² + 8x - 10
f(-4) = - 2 * (-4)² + 8 * ( -4 ) - 10
= - 32 - 32 - 10
= - 74

Tell whether the sequence is arithmetic. If it is, identify the common difference -7.-3.1.5....
9514 1404 393
Answer:
yes, 4
Step-by-step explanation:
We assume your sequence is supposed to be ...
-7, -3, 1, 5
First differences are ...
-3 -(-7) = 4
1 -(-3) = 4
5 -1 = 4
These differences are constant, so we can conclude the sequence is an arithmetic sequence, and the common difference is 4.

4 ( 4x+15)=24
Answer:
x=-9/4
Step-by-step explanation:
4(4x+15)=24 - divide both sides
4x+15=6 - move constant to the right
4x=6-15 -solve for the difference
4x=-9 - divide both sides
3x - 5 = 1 what is the value of x

Please someone help me quick!!!! It's about Domain and range, Please! Anyone!
Answer:
Step-by-step explanation:
They already said the domain of f(x) is x≥0.
The smallest value of f(x) is f(0) = 9.
Range of f(x) is y≥9.
The radicand of a square root must be non-negative, so the domain of f⁻¹(x) is x≥9.
The range is y≥0.

Write an equation that you could subtract from 4x+3y=-7 to eliminate a variable. Then solve the system.
x= 7/4 - 3/4
you just have to subtract on variable and then put it on the other side, eventually you will have to divide it all by 4, which you can't do, so it ends up as a fraction:)
Expand and simplify (x + 3)(x - 1)
I hope it helps you ❤️❤️❤️❤️
QUICK PLEASE TIMED TEST I GIVE GRINLIEST (I suck at math)
James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
The expressions are only equivalent for x = 4 and x = 6.
The expressions are only equivalent when evaluated with even values.
The expressions have equivalent values for any value of x.
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
The expressions have equivalent values if x = 8.

Which equation has the solution n = 11?
7n − 8 = 62
8n + 6 = 102
3n + 12 = 45
5n − 20 = 25
Answer:
3n+12=45
Step-by-step explanation:
Because if you take 2 and put it in the place of n 32+12 =45 and take 45 and divide it by 12 and you will get 11.

Step-by-step explanation:
according to the property √a/√b=√a/b, which choice is equivalent to the quotient below? √72/2
According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.
What is square root?The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number.
Given
[tex]\sqrt{\frac{72}{2} }[/tex]
= [tex]\sqrt{36}[/tex]
= 6
According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex]
[tex]\sqrt{\frac{72}{2} }[/tex] = [tex]\frac{\sqrt{72} }{\sqrt{2} }[/tex]
= [tex]\frac{6\sqrt{2} }{\sqrt{2} }[/tex]
= 6
Thus, according to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.
