Answer: 48
Step-by-step explanation:
The number of Pokemon cards in Steven's collection = x
The number of cards in Bob's collection is 4 times the amount in Steven's collection= 4x
The total number of Pokemon cards in both collections = 240
x + 4x = 240
5x = 240
x = 240/5
x = 48
The number of cards in Steven's collection is 48
Review Question: 5) f(x) = 2xsquared + 7x - 15 find f(-8)
Answer:
f(-8) = 57
Step-by-step explanation:
When x = - 8
f(-8) = 2 x (-8)² + 7 x (-8) - 15
f(-8) = 2 x 64 - 56 - 15
f(-8) = 128 - 56 - 15
f(-8) = 128 - 71
f(-8) = 57
[tex]\sf f(x) = 2x^2 + 7x - 1[/tex]
Just substitute the value of x as (-8) .
[tex]\sf f(-8) = 2(-8)^2 + 7(-8) - 15[/tex]
[tex]\sf f(-8) = 2(64) - 7(8) - 15[/tex]
[tex]\sf f(-8) = 128 - 56 - 15[/tex]
[tex]\sf f(-8) = 128 - 71[/tex]
[tex]\sf f(-8) = 57[/tex]

Need to know asap thank you god bless
Answer:
1) +9
2) -6
3) 0
4) 1

Say you’re at 0 on the number line. You go forward 7 steps and backwards 7 steps. You arrive at 0. Therefore your answer would be C.
What is the solution of (4 x minus 16) Superscript one-half Baseline = 36? x = 5 x = 13 x = 20 x = 328.
The solution of the given equation [tex](4x-16)^{1/2} = 36[/tex] is 328.
The given equation is:
[tex](4x-16)^{1/2} = 36[/tex]
What is solution of an equation?The solution of an equation is to find out the numeric value of the variable such that Left-hand side and Right-hand side becomes equal.
Squaring both sides of the given equation.
[tex][(4x-16)^{1/2} ]^2= (36)^2[/tex]
[tex]4x-16 = 36^{2}[/tex]
[tex]4x -16 =1296[/tex]

What is the solution of the equation 6x - 4 = 2(3x - 2). Explain your steps.
Answer: x= 4/3 but in decimal form =1.333
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4-(2*(3*x-2))=0
4 - 2 • (3x - 2) = 0
Pull out like factors :
8 - 6x = -2 • (3x - 4)
Solve : 3x-4 = 0
Add 4 to both sides of the equation :
3x = 4
Divide both sides of the equation by 3:
x = 4/3 = 1.333
Answer:
x= undefined
Step-by-step explanation:
In order to make u understand , if u multiply 2(3x-2) it becomes 6x-4 which is the exact same as the left hand side . Therefore u cant find x from here in this manner .
For this however we can try the method bellow .
Lets say f(x)=y=6x-4=2(3x-2)
we can get the followig points for inserting domains and finind the domains . we can make graph for each . (We will not do them however)
As we have seen that both of those parts of the equation are one and the same so they will produce the exact same Line or curve .
Therefore every signle points on them r the same exact points and there fore they are the same exact line .
So the value of x is undefined and can be anything between every points on that line (Which can be infinit amounts of points) .

who will give correct answer i make him / her as a brainlists
Answer:
150cm^2
Step-by-step explanation:
Let the side of a cube = a cm
Volume of the cube = a³ = 125
Or, a³ = 5³
Or, a = 5 cm
Surface area of the cube = 6a²
Or, Surface area of the cube = 6×5×5
Or, Surface area of the cube = 150 cm²
calculate the rate of change from the graph below
Answer:
The rate of change is 0.75 gallons per minute
Step-by-step explanation:
The rate of change of the linear relation is represented by the slope of the line which represents this relation
The rule of the slope of a line is
m = Δy/Δx, where
Δy is the vertical changeΔx is the horizontal changeFrom the given graph
∵ The line passes through points (0, 0) and (4, 3)
∴ Δx = 4 - 0 = 4
∴ Δy = 3 - 0 = 3
→ Use the rule of the slope above to find the slope of the line
∴ m = [tex]\frac{3}{4}[/tex] = 0.75
∵ The x-axis represents the time in minutes
∵ The y-axis represents the amount in gallons
∵ m represents the rate of change
∴ The rate of change = 0.75 gallons per minute

Answer:
x = 33°
explanation:
The interior angles sum up to 180°
solve:
x + 20° + 4x - 5° = 180°
x + 4x + 20° - 5° = 180°
5x + 15° = 180°
5x = 180° - 15°
5x = 165°
x = 33°
Answer:
x = 33
Step-by-step explanation:
Sum of consecutive interior angles = 180°
⇒ (x + 20) + (4x - 5) = 180
⇒ 5x + 15 = 180
⇒ 5x = 165
⇒ x = 33

To make a big batch of cookies for her father, Annmarie needs 1 1 4 pounds of chocolate chips, 3 4 pounds of walnuts, and 12 ounces of raisins. How many ounces of these three ingredients does she need in all?.
She will need 68 ounces in total for all three ingredients.
What will be the total ounces for all three ingredients?It is given that
For chocolate chips, she has = [tex]\dfrac{11}{4}[/tex] pounds
For walnuts, she has = [tex]\dfrac{3}{4}[/tex] pounds
For raisins, she has= 12 ounces
We know that,
[tex]\rm 1 \ pound = 16 \ ounces[/tex]
[tex]\rm For \ chocolate \ chips, she\ has = \dfrac{11}{4} \times 16 }=44 \ ounces[/tex]
[tex]\rm For \ walnuts,\ she\ has = \dfrac{3}{4} \times 16 }=12\ ounces[/tex]
[tex]\rm For\ raisins, she \ has= 12\ ounces[/tex]
so the total number of ounces she has will be the sum of all
[tex]=44+12+12 =68\ ounces[/tex]
Thus she will need 68 ounces in total for all three ingredients.

Jane is helping the librarian stack books on some new shelves. She is to stack 116 books on 16 shelves. The librarian told her to put the same number of books on each of the 16 shelves. Describe a different way that Jane can use to determine the number of books she should put on each shelf.
Answer: The number of books she should put on each shelf = 7
Step-by-step explanation:
Given: Total books = 116
Total shelves = 16
To determine : The number of books she should put on each shelf, we first divides the total number of books by the total shelf.
[tex]116\div 16=7\dfrac14[/tex]
So she can put 7 books in each shelf such that (7x16=) 112 books got placed and (116-112=)4 books left.
Hence, The number of books she should put on each shelf = 7.
