Answer A B C :) struggling a bit
Answer:
7ab
y³
e/f
Step-by-step explanation:
a*b*7= 7ab
y*y*y= y³
[tex]\frac{x^n}{x^y}=x^{n-y}\\\\\frac{e^3*f}{e^2*f^2}=\frac{e}{f}\\[/tex]
Answer:
a) 7ab
b) y^3
c) e/f
Step-by-step explanation:
a) when multiplying two variables, u can just put them right next to each other, e.g. b x c = bc
when numbers are added, same goes, they just go before the variable, hence the 7ab. If u had something like 7ab x 8 then you'd just multiply the 8 with the 7 and get 56ab
b) imagine y= 2. if u had 2 x 2 x 2, that would be 8 which is also 2^3. When any number is multiplied by itself n times, it's raised to that power. which is why y x y x y = y^3. y is being multiplied by itself 3 times.
c) If u had [tex]\frac{4*2}{2}[/tex], that would = 8/2 = 4 because it would simplify. in the fraction, you could also reduce the 2 since it appears in both the numerator and denominator.
same thing here: both the numerator and denominator have 2 e and 1 f so they get crossed out, leaving e/f
hope this helps!
Find the inequality represented by the graph.
Answer:
y > 1/3 x - 3
Step-by-step explanation:
First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).
Find the change of y over the change of x to get the slope of the line.
(-2 - (-3))/(3 - 0) = 1/3
Since the line intercepts the y axis at (0, -3), the equation of the line would be
y = 1/3x - 3
We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents
y > 1/3 x - 3

Find the length of the hypotenuse of a right triangle if the legs each measure 10
feet
Answer:
14.14 feet
Step-by-step explanation:
hyp² = 10² + 10² = 100 + 100 = 200
hyp = √200 = 14.14 feet
In 5 1/2 hours of driving, Samuel traveled 264 miles. At that rate, how long would it take him to travel 348 miles?
Answer: It will take Samuel 7 1/4hours to travel 348miles
Step-by-step explanation:
Step 1
Time spent in Driving = 5 1/2 hrs
Distance he drove = 264 miles
There the speed he drove at = Distance / Time
Speed = Distance / =Tme
= 264/ 5 1/2= 264/ 11/2= 264 x 2/ 11=528/11= 48 miles per hour
Step 2
At The same rate of 48miles per hour, it will take him to travel 348 miles
Therefore the time taken = Distance / speed
Time = 348 miles/48 miles per hour
Time=7.25 = 7 1/4 Hours
Help me ??????????????????
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = - 2x² - 12x - 16
To complete the square the coefficient of the x² term must be 1
Factor out - 2 from - 2x² - 12x
f(x) = - 2(x² + 6x) - 16
add/ subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16
= - 2(x + 3)² + 18 - 16
= - 2(x + 3)² + 2 ; y = 2

PLEASE HELP ILL GIVE BIRRELANTIST
Answer:
A.) 555 in.^2
Step-by-step explanation:
When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.
You can cut that trapezoid into two triangles and one rectangle.Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work). We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.44 - 30 = 14
14/2 = 7
Now that we filled in the information not listed, we can finally solve:
The base of one triangle is 7 inches, and the height is 15 inches.
Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).
But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).
7 x 15 = 105
The area of both triangles combined: 105 in.^2
Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).
15 x 30 = 450
The area of the rectangle: 450 in.^2
Now, the final step. Addition. All you need to do is add up all the sums, and you're done.
450 + 105 = 555
The area of entire figure: 555 in.^2
NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)

It’s solving systems of equations
Answer:
7 quarters, 8 nickels
Step-by-step explanation:
So the system of equations you have is:
x + y = 15
0.25x + 0.05y = 2.15
Here's how to solve:
first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:
25x + 5y = 215
Then, you can divide both sides by 5 to simplify it more:
5x + y = 43
Now, you have the system of equations:
5x + y = 43
x + y = 15
Now subtract the two equations:
4x = 28
divide both sides by 4
x = 7
plug x = 7 into the equation x + y = 15 to solve for y:
7 + y = 15
subtract 7 from both sides
y = 8
So you know that there are 7 quarters and 8 nickels.

You burned a CD of your music and then created an artistic CD label
for it. Your friends liked it so much that they all asked if you would make CD labels
for the CDs of their music. So far, it has taken you 6.5 hours to create 3 CD labels.
How long will it take to create 4 more labels? Round your answer to the nearest tenth.
Answer:
I think it's 8.7
Step-by-step explanation:
if you divide 6.5 by 3, you get 2.16666666667, so that is how long it takes to make 1 CD liable. Multiple that by 4 and round and you get 8.7.
If I'm wrong I apologize :(
