equation for X.
3x - 15 = -30
Answer:
X = -5
Step-by-step explanation:
3x - 15 = -30 You want to isolate tha variable
3x= -30+15 Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30
3x= -15
x= -15÷3 Divide x by 3 in order to get rid of the 3. Do it to the other side
x=-5

A bookstore costs $96 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point
for this bookstore?
Answer: The break even point is when they have sold 16 books and have made $288
Step-by-step explanation: The costs are modeled in the equation y = 12x + 96. x is the number of books sold.
The earnings are modeled by he equation y = 18x.
Substitute 18x for y and solve for x.
18x = 12x + 96 Subtract 12x from both sides.
6x = 96 Divide both sides by 6
x = 16
Substitute into the original equations to solve for y
y = 12(16) + 96
y = 192 + 96
Y = 288
y = 18(16)
y = 288

Find the slope of each piece of the antler on the graph below. Write answers in the simplest form into the table.
Answer:
1.) slope = 2
2.) slope = [tex]-2\frac{2}{3}[/tex]
3.) slope = [tex]\frac{2}{3}[/tex]
4.) slope = [tex]\frac{1}{4}[/tex]
5.) slope = [tex]1\frac{8}{9}[/tex]
6.) slope = -2
7.) slope = -3
Step-by-step explanation:
In order to find the slope we have to divide they "y" value (the number of units by which the piece of antler goes up) by the "x" value the number of units by which the piece of antler goes to the side). Notice the if the antler moves to the left as it foes up then the "x" value is negative.
Now as I said before we know this......
Let "m" be the slope, then....
[tex]m = \frac{y}{x}[/tex]
So now we just have to plug in the y and x values for each antler and we will get the slopes for each one of them.
1.)
[tex]m = \frac{y}{x}[/tex]
[tex]m= \frac{4}{2}[/tex]
[tex]m = 2[/tex]
2.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{4}{-1.5}[/tex]
[tex]m = -2\frac{2}{3}[/tex]
3.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{2}{3}[/tex]
4.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{1}{4}[/tex]
5.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{8.5}{4.5}[/tex]
[tex]m = 1\frac{8}{9}[/tex]
6.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{2}{-1}[/tex]
[tex]m= -2[/tex]
7.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{3}{-1}[/tex]
[tex]m = -3[/tex]

What percentage of the block is shaded in?
Answer:
7/10ths
Step-by-step explanation:
There are ten blocks all together, which is where the 10 comes from, there is 7 shaded that is where the 7 comes from.
Answer:
The percentage is 70%.
Step-by-step explanation:
There are 10 spaces total, and 7 are shaded in. 7 divided by 10 is 0.7.
0.7 as a percentage is 70%.
So 70% of the block is shaded in.

f(x) = 2x² + x – 4
Find f(-10)
NEED IT FAST
Answer:
[tex]f(-10)=186[/tex]
Step-by-step explanation:
We can use substitution to find the value of [tex]f(-10)[/tex].
[tex]f(x) = 2x^2+x-4[/tex]
[tex]f(-10) = 2(-10)^2-10-4[/tex]
[tex]=200-10-4[/tex]
[tex]=186[/tex]
∴ [tex]f(-10) =186[/tex]
Hope this helps :)
Answer:
The value of f(-10) is equal to 186.
Step-by-step explanation:
We are given the function:
[tex]f(x) = 2x^2 + x - 4[/tex]
We are told to find the value of:
[tex]f(-10)[/tex]
If we pay close attention, we can see a transition between:
[tex]f(x) \rightarrow f(-10)[/tex]
We have turned x into -10, making x = -10.
Therefore, we can change the value of x in the entire function to -10.
[tex]f(-10)=2(-10)^2+(-10) - 4\\\\f(-10) = 200 - 10 - 4\\\\f(-10) = 186[/tex]
Therefore, f(-10) = 186.

Is this sequence arithmetic, geometric, or neither?
Answer:
Geometric sequence
.Step-by-step explanation:
Geometric sequences are defined by an initial value and a common ratio . If a sequence does not have a common ratio or a common difference, it is neither an arithmetic nor a geometric sequence. You should still try to figure out the pattern and come up with a formula that describes it.
Answer: Neither

Calculate the frequency of light that has a wavelength of
4.25 x 10^-9m and a velocity of 300 m/s.
Answer:
The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.
Wavelength of light = velocity of light / frequency of light
λ = v/f
λ = Wavelength of light, meters
v = Velocity of light (c = 3.0 x 108 m, for speed of light if not otherwise defined)
f = frequency of light, Hz

Answer:
The system is consistent; it has one solution ⇒ D
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, then the system is consistent independent and has exactly one solutionIn the given system of equations
∵ -2y + 2x = 3 ⇒ (1)
∵ -5y + 5x = 12 ⇒ (2)
→ By comparing equations (1) and (2)
∵ -2 ≠ -5
∵ 2 ≠ 5
∵ 3 ≠ 12
→ By using the 3rd rule above
∴ The system is consistent independent and has exactly one solution
∴ The system is consistent; it has one solution
Which step could be used to solve x + 3.6 = negative 1.7 for x in one step? Select two options. Add 3.6 to both sides. Add Negative 3.6 to both sides. Add 1.7 to both sides. Add Negative 1.7 to both sides. Subtract 3.6 from both sides.
Answer:
Subtract 3.6 from both sides.
Step-by-step explanation:
Given
[tex]x + 3.6 = -1.7[/tex]
Required
Solve in one step
There are two ways to go about it.
1. Collect Like Terms
[tex]x + 3.6 = -1.7[/tex]
3.6 and -1.7 are like terms, so the equation becomes
[tex]x = -1.7 - 3.6[/tex]
[tex]x = -5.3[/tex]
2. Subtract 3.6 from both sides
[tex]x + 3.6 = -1.7[/tex]
This becomes
[tex]x + 3.6 - 3.6 = -1.7 - 3.6[/tex]
[tex]x = -5.3[/tex]
Hence, the last option answers the question.
Answer:
Option 2and 5 are correct.
Step-by-step explanation:
-Add -3.6 to both sides
-Subtract 3.6 from both sides

lily likes to collect records. Last year she had 4 records in her collection. Now she has 7 records. What is the percent increase of her collection?
Answer:
75% increase
Step-by-step explanation:
First we need to figure out how many new records she got this year...
7-4 = 3 new records.
Now, we need to know how many times 4 goes into 100%....
100 ÷ 4 = 25%
This tells us that a single record this year is a 25% increase.
Now, we multiply 25% by 3 to get 75% as our final answer
Hope this Helps!!! :)
