QUICK! WHAT IS THIS ANSWER?
Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
a)we want to expand the following expression:
[tex] \displaystyle - \frac{1}{4} ( - 8x + 12y)[/tex]
well to do so we consider distributive property thus distribute:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)[/tex]
reduce fraction which yields:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)[/tex]
simplify Parentheses:
[tex] \displaystyle \boxed{ 2x - 3y}[/tex]
b)in the expression there's a common factor of 4 therefore factor it out:
[tex] \displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}[/tex]

Evaluate this expression (3+4)-4/42+3(4+2)/3
Answer:
Step-by-step explanation:
Use PEDMAS
(3 + 4) - 4/42 + 3(4 +2)/3 = 7 - [tex]\frac{4}{42}[/tex] + 3 * [tex]\frac{6}{3}[/tex] {Inside parenthesis}
= 7 - [tex]\frac{2}{21}[/tex] + 6 {Division}
= 13 - [tex]\frac{2}{21}[/tex]
[tex]=\frac{13*21}{1*21}-\frac{2}{21}\\\\=\frac{273}{21}-\frac{2}{21}\\\\=\frac{271}{21}[/tex]

Harry reads that a particular element has an atom with a mass of 0.000000000012 grams. What is the weight of the atom expressed in scientific notation?
A.
1.2 × 10-9 grams
B.
1.2 × 10-11 grams
C.
1.2 × 1011 grams
D.
1.2 × 1012 grams
Answer:
Since this number is small we know that the exponent will be negative.
In scientific notation the decimal must be between the first two NON zero numbers. So move the decimal and count how many positions it was moved.

Is (5, 0) a solution to the equation y = x + 5?
Guys I need help
Answer:
no
Step-by-step explanation:
substitute the x- coordinate 5 into the equation and if the result is equal to the y- coordinate 0 then it is a solution
y = 5 + 5 = 10 ≠ 0
Then (5, 0 ) is not a solution to the equation

3.14x-7x^2=0 <--> 7x(2-x)=0
4.24x-6x^2=0 <--> 6x(4-x)=0
Step-by-step explanation:
just try to expand the answer given for example when you look at no.1, 2x•x=2x^2 so look for the equation where there is a 2x^2 in it.
for finding the solution, for example when you look at no.1 again, you have 2x=0 so x=0/2=0 and you also have x+3=0 so x=-3
this applies to all the pther no.
i reallyyy need help ! a p e x
Answer:
D
Step-by-step explanation:
Because the closed dot is connected to the one less than 1, we know that one of the equation is less than or equal to 1. So this eliminates A.
B makes no sense because it shows two equations for when x < 1. So this one can be ruled out immediately.
We also notice the shape of the functions, the one on the bottom looks like a cube, you can make out the beginning of the chair shape. So the one that is less than or equal to 1 is the cubic function. Which eliminates C.
This leaves D and you can plug in values of x and y to confirm this is correct.
Answer:
Step-by-step explanation: First you look at the left side of the graph. You can tell by the shape that it is an x^3 function. also the filled in circle means inclusive. so we know that when x <= (whatever number). It is impossible to tell for sure with this graph if it is on 1. for the first part. the only answer that has less then or equal to is the last one, D. So the answer is D. You can look at the right side that it is open circle. So we know it is >. So we can see the bottom part of D has that as well
Which of the following is equivalent to (x+5)(2x^2 +8)?
A. (x+5)(2x^2)• (X+5)(8)
B. (x+5)(2x^2)+(x+5)(8)
C. (x+5)(2x)+(x+5)(8)
D. (x+5)(2x)• (x+5)(8)
Answer:
(x+5)(2x^2 +8)
Multiply (x+5) in both sides
(x+5)(2x^2) × (x+5)(8)

Write the equation of the line that passes through the points (8, –1) and (2, –5) in standard form, given that the point-slope form is y + 1 = (x – 8).
Answer:
A linear equation in the standard form is written as:
y = a*x +b
where a is the slope and b is the y-intercept.
If we know that the line passes through the points (a, b) and (c, d), then the slope can be written as:
a = (d - b)/(c - a)
So we know that our line passes through the points (8, -1) and (2, -5)
then the slope will be:
a = (-5 - (-1) )/(2 - 8) = (-4/-6) = 2/3
Then our line is something like:
y = (2/3)*x + b
to find the value of b, we can use the fact that we know that our line passes through the point (2, -5)
this means that when x = 2, we must have y = -5
replacing these values in the equation we get:
-5 = (2/3)*2 + b
-5 = 4/3 + b
-5 - 4/3 = b
-15/3 - 4/3 = b
-19/3 = b
then the equation is:
y = (2/3)*x - 19/3
(in the question you wrote the point-slope form, but you can see that it does not work for the second point, so there may be a mistake there, as the slope is missing)
The actual equation in the point-slope form is:
y + 1 = (2/3)*(x - 8)
Answer:
The answer is 2x + -3y = 19

B
Step-by-step explanation:
Profit= Revenue - cost
so just subtract the two equations
(700x+100)-(600x+500)
100x-400 which is answer choice B
Answer:
Step-by-step explanation:
so subtract the cost function from the revenue function
700x + 100
-(600x + 500)
profit(x) = 100x -400
Mike, a Salvation Army bell ringer, has 20% as many quarters as nickels in his cup. If Mike has $6.00 in quarters and nickels, how many nickels does he have?
5.8 Nickels
Step-by-step explanation:
Let x rep no of Nickels in Mike's cup
Then x - 0.2 = Number of quarters in Mike's cup
0.2x = Amount of money that mike has from the nickels
1 ( x - 0.2) = Amount of money that Mike has from the quarter
Then,
0.2x + 1 (x - 0.2) = 6
Expand the bracket
0.2x + x - 0.2x = 6
x = 6
Recall
x - 0.2 = 0
6 - 0.2 = 5.8
Therefore, Mike has 5.8 nickels for the quarter

(5.4)
O B. (5,1)
10
(5,-3)
O C. (5,-)
O D. (10,1)
SUBMIT
Answer:
c
Step-by-step explanation:
To find the midpoint the formulas
x=x1+x2/2 and y=y1+y2/2 are used
in this case x1 is 5,x2 is 5,y1 is 4 and y2 is -3
therefore
x=5+5/2.
=10/2
=5
y=4+(-3)/2
=1/2
The midpoint of a line segment divides the line into equal segments
The midpoint of the line segment is (5,1/2)
The endpoints of the line is given as:
(5,4) and (5,-3)
The midpoint of the line is calculated as:
(x,y) = 0.5(x1 + x2, y1 + y2)
So, we have:
(x,y) = 0.5(5 + 5, 4 - 3)
Evaluate the sum and difference
(x,y) = 0.5(10, 1)
Evaluate the product
(x,y) = (5, 1/2)
Hence, the midpoint of the line segment is (5,1/2)
