Answer:
[tex]\huge\boxed{(f-g)(2)=17}[/tex]
Step-by-step explanation:
[tex](f-g)(x)=f(x)-g(x)\\\\f(x)=2x^2+8;\ g(x)=x-3\\\\(f-g)(2)=f(2)-g(2)\\\\f(2)\ [g(2)]-\text{substitute}\ x=2\ \text{to}\ f(x)\ [g(x)]\\\\f(2)=2(2^2)+8=2(4)+8=8+8=16\\g(2)=2-3=-1\\\\(f-g)(2)=16-(-1)=16+1=17[/tex]
-8(-x - 7) = 120
I forgot how to do equations pls help
Answer:
x = 8
Step-by-step explanation:
Given
- 8(- x - 7) = 120 ( divide both sides by - 8 )
- x - 7 = - 15 ( add 7 to both sides )
- x = - 8 ( multiply both sides by - 1 )
x = 8

Point I is on line segment \overline{HJ}
HJ
. Given HI=2x,HI=2x, HJ=4x,HJ=4x, and IJ=4x-10,IJ=4x−10, determine the numerical length of \overline{IJ}.
IJ
.
Answer:
IJ = 20
Step-by-step explanation:
Point I is on the lines segment HJ. So,
HJ = HI + IJ
Putting all the given values, we get :
4x=2x+4x-10
Taking like terms together, we get :
-2x=-10
x=5
Put the value of x in IJ = 4x-10
IJ = 4(5)-10
IJ = 20
Hence, the value of IJ is 20.

Answer:
It is C, because to find volume you must use the formula l×w×h, or length times the width times the height. (cm^3)
Answer:
C
Step-by-step explanation:
Unlike area that's cm² because it's like A= L*W
Volume is cm³ because it's like A= L*W*H
Sosa received $90 in gift cards to Coffee Crazee and each drink she purchases costs $4.75. Sosa also received $75 in gift cards to Fran's Frappes and each drink she purchases cost $3.25. How many drinks will Sosa have to purchase in order to have the same amount remaining on the gift cards from both shops? * 33
Answer:
90 -4.75x = 75 -3.25x
90-75= 4.75x-3.25x
x= 10
Step-by-step explanation:
Answer:
10 drinks
Step-by-step explanation:
We can set up an equation to find the amount of drinks needed, x.
[tex]90-4.75x = 75-3.25x[/tex]
Now let’s solve for x by isolating it on one side of the equation.
Subtract 75 from both sides:
[tex]15 - 4.75x = -3.25x[/tex]
Add 3.25x to both sides:
[tex]15-1.5x=0[/tex]
Add 1.5x to both sides:
[tex]15 = 1.5x[/tex]
Divide both sides by 1.5:
[tex]x = 10[/tex]

Find the volume of the sphere. Use 3.14 for it. Round to the tenths if necessary. Don't forget to include your
label in the answer. Use ^ to show an exponent.
Hey there! I'm happy to help!
First let's find the radius. The radius is half of the diameter.
9/2=4.5
Here's how to find the volume of any sphere.
You cube the radius.
4.5³=91.125
You multiply by 3.14
91.125(3.14)=286.1325
And finally we multiply by 4/3.
286.1325(4/3)=381.51
We round to the nearest tenth, giving us a volume of 381.5 in^3.
Have a wonderful day! :D

The Navy Pier Ferris Wheel in Chicago has a circumference that is 56% of the circumference of the first Ferris wheel built in 1893. The Circumfrence of the Navy Peir wheel is 439.6 ft. What is the radius of the first ferris wheel?
Hey there! I'm happy to help!
439.6 is 56% of the first Ferris wheel. The word is means equals, so we can set up the following equation. We will call the original wheel w.
439.6=0.56w
We divide both sides by 0.56
w=785
We divide by 3.14 to find the diameter.
785/3.14=250
Radius is half of the diameter.
250/2=125
The radius of the first Ferris wheel is 125 ft.
Have a wonderful day! :D
Step-by-step explanation:
439.6=0.56w
We divide both sides by 0.56
w=785
We divide by 3.14 to find the diameter.
785/3.14=250
Radius is half of the diameter.
250/2=125
The radius of the first Ferris wheel is 125
125ft.

∠A and \angle B∠B are vertical angles. If m\angle A=(3x+3)^{\circ}∠A=(3x+3) ∘ and m\angle B=(4x-8)^{\circ}∠B=(4x−8) ∘ , then find the value of x.
Answer:
The value of x is 11 degrees
Step-by-step explanation:
Here, given that two angles are vertical angles, we are interested in calculating the value of x. We simply want to use an important property of vertical angles to get the value of x as given in the question.
When we talk of vertical angles, they are angles which lies on opposite side to each other when we have two intersecting line.
By property, vertically opposite angles are equal.
Thus, in this case, we are to equate the angles we are having since they are both vertical angles;
Thus,
Mathematically;
angle A = angle B
3x + 3 = 4x -8
Collect like terms;
4x-3x = 3 + 8
x = 11 degrees
