Answer:
f(-2) = 0
Step-by-step explanation:
Given that:
f(x) = bx^2 + 32
f(2) = b(2)^2 + 32
f(2) = 4b + 32
f(2) = 4b = -32
f(2) = b = -32/4
f(2) = b = -8
Thus;
f(-2) = -8(-2)^2 + 32
f(-2) = -8(4) + 32
f(-2) = -32 + 32
f(-2) = 0

Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2
Answer:
Yes!
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation
[tex]4\left(n\right)-3=-2\left(n\right)+9[/tex]
remove the parentheses
[tex]4n-3=-2n+9[/tex]
Add 3 to both sides
[tex]4n-3+3=-2n+9+3[/tex]
Simplify
[tex]4n=-2n+12[/tex]
Add 2n to both sides
[tex]4n+2n=-2n+12+2n[/tex]
Simplify
[tex]6n=12[/tex]
Divide both sides by 6
[tex]\frac{6n}{6}=\frac{12}{6}[/tex]
Simplify
[tex]n=2[/tex]
Therefore, the value of n = 2.
Hence,
Yes!
The solution to the equation is n = 2

The length of a rectangle is 3 inches less than three times its width. The perimeter of the rectangle is 34 inches. Find the dimensions of the rectangle
Given:
The length of a rectangle is 3 inches less than three times its width.
The perimeter of the rectangle is 34 inches.
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then, the length of a rectangle is 3 inches less than three times its width.
Length of the rectangle = 3x-3
Now, perimeter of the rectangle is
[tex]Perimeter=2(Length + Width)[/tex]
[tex]Perimeter=2(3x-3+x)[/tex]
The perimeter of the rectangle is 34 inches.
[tex]34=2(4x-3)[/tex]
[tex]34=8x-6[/tex]
[tex]34+6=8x[/tex]
[tex]40=8x[/tex]
Divide both sides by 8.
[tex]\dfrac{40}{8}=x[/tex]
[tex]5=x[/tex]
The value of x is 5. So, width of the rectangle is 5 inches.
[tex]Length=3x-3[/tex]
[tex]Length=3(5)-3[/tex]
[tex]Length=15-3[/tex]
[tex]Length=12[/tex]
Therefore, the length of the rectangle is 12 inches and the width of the rectangle is 5 inches.

The ratio of the three angles of a triangle is 2:3:5. What are the three angles of the triangle?
FIRST STEP:
2x + 3x + 5x = 180
10x = 180
x = 18
SECOND STEP:
2*18 = 36
3*18 = 54
5*18 = 90
36:54:90
PLZ MARK AS BRAINLIEST
Answer:
let ratio be 2x,3xand 5x
Step-by-step explanation:
2x+3x+5x=180(sum of interior angle of triangle)
10x=180
x=180/10=18
:.required angle
2x=2×18=36
3x=3×18=54
5x=5×18=90
HELP ME OUT PLEASE!!!
Answer:
So the scale factor would be the length of the new rectangle divided by the length of the corresponding side for the original rectangle. So the scale factor is 1/2. Note: If you're going from a bigger shape to a smaller one, you know that the scale factor must be less than 1.

What is f /4 − 24 = −28
Answer: i assume you're looking for F, if so F = -16
Step-by-step explanation:
you would start by adding +24 to each side of the equation, giving you f/4 = -4
then, you would multiply each side of the equation by 4, giving you f = -16

What is the answer to this any body know it??????????
Answer:
2n+10
Step-by-step explanation:
you just distribute the -2 and you get -14+2n+4 and then add and you'll get 2n+10
if you are solving for the variable n then you would want your equation like this 2n+10=0
next you would put the 10 on the other side of the equation and have 2n=-10
finally you would divide by 2 and get n=-5

Express $0.\overline{5}$ as a common fraction in lowest terms.
=======================================================
Explanation:
[tex]0.\overline{5}[/tex] means that the 5's go on forever because of that horizontal bar over top. So we can write it as [tex]0.\overline{5} = 0.55555\ldots[/tex]
The three dots indicate it goes on forever following that pattern.
Let
x = 0.55555....
Multiply both sides by 10 to move the decimal point 1 spot to the right
10x = 5.55555....
Notice how both x and 10x involve a decimal number such that we have a string of 5's going on forever. If we subtract the two equations, then 10x-x becomes 9x, while the (5.55555....) - (0.55555....) simplifies to 5. The decimal portions cancel out when we subtract since they line up perfectly. We're effectively subtracting 5-0 when we cross off the decimal portions.
After those subtractions, we're left with 9x = 5 which solves to x = 5/9 when you divide both sides by 9.
Use of a calculator should show that 5/9 = 0.555555.... to help confirm the answer. Your calculator may show the last digit to be a 6 instead of a 5, but this is due to rounding. Ideally you should have a string of infinitely many 5's, but the calculator can only how so many digits.
answer asap ty.!
Thanks
Answer:
x=0
Step-by-step explanation:
5-9+3x = -10+6

+4 . +4 (Both sides)
3x = 0
/3 /3 . (divide both sides by 3)
x=0

Kellie is purchasing the package of dog food shown (dog kibble 7pounds) how many 8 ounce servings can she feed her dog
Answer:
14 servings
Step-by-step explanation:
Step 1
We convert 7 pounds to ounces
0.0625 pound = 1 ounce
7 pounds = x
Cross Multiply
0.0625x = 7
x = 7/0.0625
x = 112 ounces
Step 2
The number of 8 ounce servings she can give to her dog is calculated as:
8 ounces = 1 serving
112 ounces = x servings
Cross Multiply
8 × x = 112 × 1
8x = 112
x = 112/8
x = 14 servings
Therefore, the number of 8 ounce servings she can feed her dog is 14
