Any one Know the Answer To This Algebra 1
Answer:
The correct answer is B. -3.
Step-by-step explanation:
To solve this problem, we need to plug in -3 for all of the values of x in the equation. If we do this, we get:
f(x) = 2x + 3
f(-3) = 2(-3) + 3
Now, we can just simplify the expression found on the right side of the equation using PEMDAS. First, we should perform the multiplication.
f(-3) = -6 + 3
Next, we should add our final two terms together.
f(-3) = -3
Therefore, the correct answer is -3.
Hope this helps!

5-x=12
Answer:
x=-7
Step-by-step explanation:
Subtract 5 from both sides.
−x=12−5
Subtract 5 from 12 to get 7.
−x=7
Multiply both sides by −1.
x=−7
Answer:
x = -7
Step-by-step explanation:
When subtracting negative numbers from positive it's like adding. The rules are a bit wonky I know haha. So your problem would look like this when "x" is solved:
5 - -7 = 12

Solve for h in the proportion.
28/24 = 42/h h= ?
Answer:
h = 36Step-by-step explanation:
[tex] \frac{28}{24} = \frac{42}{h} \\ [/tex]
Reduce the fraction on the with 4
We have
[tex] \frac{7}{6} = \frac{42}{h} \\ [/tex]
Cross multiply
That's
[tex]7h = 6 \times 42 \\ 7h = 252[/tex]
Divide both sides by 7
[tex] \frac{7h}{7} = \frac{252}{7} \\ [/tex]

The median will remain unchanged and the mean will decrease.
Answer:
The median will remain unchanged and the mean will increase.
Step-by-step explanation:
The effect that will removing all outliers have on the mean and median of the data set is; C. median will remain unchanged and the mean will increase.
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
The Median represents the middle value of the given data when arranged in a particular order.

Answer:
x = 30
Step-by-step explanation:
[tex]\frac{3}{5}[/tex](30) + [tex]\frac{1}{3}[/tex](30) = 28
[tex]\frac{3}{5}[/tex](30) = 18
[tex]\frac{1}{3}[/tex](30) = 10
18 + 10 = 28
[tex] \frac{3}{8} x + \frac{1}{3} x = 28[/tex]

List multiples to find LMC of 27 and 45
Answer:
135
Step-by-step explanation:
I think you mean the LCM instead of LMC. LCM stands for Least Common Multiple. Anyway, some of the multiples of 27 are 27, 54, 81, 108, and 135. Some multiples for 45 are 45, 90, 135. We can see here that 27 and 45 share the mutiple of 135 which is the first number they have in common.

Aubrey, a pet store employee, wants to fit two fish tanks on one table. One fish tank is 1/6 of a foot wide and the other fish tank is 5/6 of a foot wide. When placed next to each other, what is the total width of the two fish tanks? Write your answer as a fraction or as a whole or mixed number.
Answer:
6/6 or one foot.
Step-by-step explanation:
If one of the fish tanks is 5/6 of a foot wide, and the other is 1/6, add them together.
5/6+1/6=6/6 or 1 foot wide. 6/6 means a whole number.
The total width of the two fish tanks as per the given relation is equal to 1 foot.
To find the total width of the two fish tanks when placed next to each other, add their widths.
The widths are given as fractions of a foot, so add them directly:
Width of the first fish tank = 1/6 foot
Width of the second fish tank = 5/6 foot
Total width of the two fish tanks = (1/6) + (5/6)
To add fractions, they need to have the same denominator.
Here, both fractions already have the same denominator (6),
So, simply add their numerators:
Total width = (1 + 5)/6
Total width = 6/6
Now, 6/6 is equal to 1.
Therefore, the total width of the two fish tanks is 1 foot.

Answer:
0
Step-by-step explanation:
Since f(x)=18 you would do:
f(x)= 18(2)-2(18)+3
f(x)=36-36+3
Final Answer: 0
Step-by-step explanation:
f(x) = x^2 - 2x + 3
f(x) = 18
x^2 - 2x + 3 = 18
x^2 - 2x + - 15 = 0
(x-5) (x+3) = 0
x = 5 (or) x = -3

3.79 for 4 avoacado how much is one
who ever answers it gets to be the briliets
So, here we know that for 4 avocados it costs $3.79.
First, lets round 3.79 to the nearest whole because even if we don't it will be the same rounded.
We now have $4.00.
What we do now is we look at the rounded cost and the amount of avocados.
So, for 1 avocado it cost 1 dollar.
If we were to do it without rounding it to the nearest whole we would have $1.05.
