The graph of F(x), shown below, has the same shape as the graph of G(x) = x^3, but it is shifted down 2 units. What is its equation?
Find the slope of the line passing through the points (5, 4) and (5, -5)
Answer:
NO Slope
Step-by-step explanation:
slope of the line passing through the points (5, 4) and (5, -5)
slope = y2 - y1 = -5 - 4 = -9
x2 - x1 5 - 5 0
see attached.
in this graph of a line x = 5, no matter what the value of y is.
the horizontal change is 0 and the vertical change is any y value
therefore, there is NO Slope
Which expression is a Product?
A) 8(6 + 3)
8
B) _
(6 +3)
C) 5 (2) + 2(6 x 3)
D) 5(2 + 3) - 4 (8 +1)
Answer:
thats what i got
Step-by-step explanation:
which equation is correctly rewriitten to solve for x
x/r - s = t
x/r - s = t
Add s to both sides.
x/r - s + s = s + t
x/r + 0 = s + t
x/r = s + t
Multiply both sides by r.
r(x/r) = r(s + t)
x = r(s + t)
Understand?
Answer:
x=tr/s
Step-by-step explanation:
x/r-s=t
x-s=t×r
x-s/s=tr/s
x=tr/s
(1) In the State of Michigan there is a 6% sales tax, so if you purchase a
new pair of shoes for $75 how would you set up the ratio to calculate your
tax? *
Answer:
1:0.06
Step-by-step explanation:
since there is a 6% sales tax, which is the same as 0.06. to calculate your tax, you would multiply both of the sides of the ratio by 75, and the left side will show you subtotal of what you are buying, the right will show tax.
Nick has a $45 Starbucks gift card. He purchased the same latte six times and has $18 left on the card. What was the price of each latte? What does the variable represent in this problem?
Answer:
The price of each latte was $4.5.
Step-by-step explanation:
6x + 18 = 45
6x = 45 - 18
6x = 27
x = 27/6
x = 4.5
The variable represents the cost of each latte.

Don't know how to express the value of X as any of those answer choices
9514 1404 393
Answer:
x = √(w(w+z))
Step-by-step explanation:
The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.
BC/AC = DC/BC . . . . . short side/hypotenuse
BC² = AC·DC . . . . . . cross multiply
x² = (w+z)w . . . . . . substitute letter values
Taking the square root and rearranging to the form of the applicable answer choice, this is ...
[tex]\boxed{x=\sqrt{w(w+z)}}[/tex]
How many solutions does 6 - 3x = 4 - x - 3 - 2x have?
Answer:
No Solution
Step-by-step explanation:
6 - 3x = 4 - x - 3 - 2x (Given)
6 - 3x = -1 -3x (combine like terms)
7 (addition)
The x cancels each other out so no solution.

Tickets to a concert cost $50 for each orchestra seat and $40 for each
balcony seat. If 1,500 tickets were sold to earn $69,000, how many
orchestra-seat tickets were sold?
A
600
B 750
h
900
1,380
Answer:
H. the number of orchestra seat is 900
Step-by-step explanation:
Step one:
let the number of orchestra seat be x
and balcony seat be y
cost of orchestra= $50 each
cost of balcony =$40 each
total tickets= 1500
x+y= 1500----------1
amount earned= $69000
50x+40y=69000--------2
The system of equation for the situation is
x+y= 1500----------1
50x+40y=69000--------2
from 1, x=1500-y
put this in equation 2
50(1500-y)+40y=69000
75000-50y+40y=69000
-10y=69000-75000
-10y=-6000
divide both sides by -10
y=-6000/-10
y=600
put y= 600 in equation 1
x+600= 1500
x=1500-600
x=900

Step-by-step explanation:
K=m-n÷y (make y the subject)
Answer:
y = [tex]\frac{n}{K - m}[/tex]
Step-by-step explanation:
When doing problems like these, you should go through the process like using PEMDAS:
P - Parenthesis ()
E - Exponents [tex]x^{2}[/tex]
M - Multiply x
D - Division ÷
A - Addition +
S - Subtraction -
1) Since there aren't any Parentheses, or exponents, we should then check for any use of Multiplication.
As shown, there are no shown methods of multiplying.
BUT there is Division, so we will do the opposite of division, which is multiplication.
K = m - n ÷ y
y(K = m - n ÷ y)y
^ Trying to multiply 'y' onto both sides, because when you do something to one side, you do to the other. ^
'y' then cancels out on one side, so you will be left with:
= m - n
But on the other side you will have:
Ky
So your problem will look like:
Ky = m - n
2) Since we are trying to get 'y' by itself, instead of multiplying now, we will be dividing, because:
K(y) = Ky or you can also say K x y = Ky
Back to the problem, we will now divide 'K' to both sides, as stated before:
What you do to one side, you do to the other:
[tex]\frac{Ky}{K} = \frac{m - n}{K}[/tex]
'K' will cancel out on one side:
[tex]\frac{Ky}{K} = y[/tex]
Leaving you with:
'y'
While the other side, will be left as:
[tex]\frac{m - n}{K}[/tex]
So your final answer will be:
[tex]y=\frac{m - n}{K}[/tex]

Step-by-step explanation:
What is the domain of the square root function graphed below?
Answer:
Option (4)
Step-by-step explanation:
Domain of a function is a set of x-values (Input values) of the function.
For the given graph of square root function,
x - values starts from x = 0 and tends to x = ∞
Therefore, domain of the function will be,
x ≥ 0
Option (4) will be the correct option.
