Solve the system of equations using the linear combination method.
4x−2y=7
3x+2y=0
Answer:
x = 1
y = -3/2
Step-by-step explanation:
Step 1: Arrange the equations with like terms in column.
Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.
Step 3: Solve for x.
4x-2y=7
3x+2y=0
--------------
7x = 7
x = 1
Step 4: Substitute the value of x and solve for y.
4(1)-2y=7
4-2y=7
-2y=7-4
-2y=3
y=-3/2
A student did an experiment to test the hypothesis that brand name paper towels soak up water better than generic paper towels. What would be the independent variable in the student's experiment?
Answer: The independent variable is the brand and the dependant variable is the amount of water you use.
Step-by-step explanation:
The Independent variable is the condition that you change in an experiment.
The dependant variable is the condition that you measure in an experiment.
The independent variable in the student's experiment is the type of paper towel used.
In an experiment, there are three types of variables:
The independent variable : the experimenter can change or manipulate this variable in order to determine its effect on the dependent variable. The dependent variable : this is the variable whose value would be determined in the experiment.The extraneous variable : this is the variable that can affect the result of the experiment but it is not researched in the experiment.In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.

A diver dove down 20 14 feet under water and then descended 20 14 feet.
A golfer shot 2 over par (+2) on a hole. They then then shot 2 under par (−2) on the next hole.
A golfer shot 2 over par (plus 2) on a hole. They then then shot 2 under par (negative 2) on the next hole.
You have $5.50 in your pocket and then you receive $5.50 for doing your chores.You have $5.50 in your pocket and then you receive $5.50 for doing your chores.
Answer:
For the first three situations, the sum is zero.
Step-by-step explanation:
As the expenses are negative of earnings, so assuming the earning amount is positive while the spending amount is negative.
Shawna spends $20 and she earns $20,
So, the sum of the total amount is
-20+20=0
A diver dove down 20.14 feet under-water and then descended 20.14 feet.
First, the diver ascends 20.14 feet then descends the same.
As the ascending and the descending are opposite to each other.
The sum of both is
+20.14-20.14=0
So, in this case, the diver has a sum of zero.
For shooting over par the golfer have +2 points while for shooting under par the golfer have -2 points,
So, the total points are
+2-2=0
So, in this case, the golfer has a sum of zero points.
In the last case, you already have $5.50 in your pocket and then you receive $5.50 for doing your chore.
This time, there is an addition of $5.50 to the money you already have.
So, the total money, after receiving the $5.50 is
$5.50+$5.50=$11
In this case, the sum of the total amount is not zero.
Hence, for the first three situations, the sum is zero.

12. Factor completely: 64x^3 + 729
Answer:
(4 x + 9) (16 x^2 - 36 x + 81)
Step-by-step explanation:
Factor the following:
64 x^3 + 729
64 x^3 + 729 = (4 x)^3 + 9^3:
(4 x)^3 + 9^3
Factor the sum of two cubes. (4 x)^3 + 9^3 = (4 x + 9) ((4 x)^2 - (4 x) 9 + 9^2):
(4 x + 9) ((4 x)^2 - 4 9 x + 9^2)
4×9 = 36:
(4 x + 9) ((4 x)^2 - 36 x + 9^2)
Multiply each exponent in 4 x by 2:
(4 x + 9) (4^2 x^2 - 36 x + 9^2)
4^2 = 16:
(4 x + 9) (16 x^2 - 36 x + 9^2)
9^2 = 81:
Answer: (4 x + 9) (16 x^2 - 36 x + 81)
Answer:
(4x+9)(16x2−36x+81)
Step-by-step explanation:
Factor 64x3+729

Solve the following equation for a.
a-f=q
Answer:
a=q+f
Step-by-step explanation:
1. a-f=q
2. you need to do the opposite of -f which is +f to cancel it out
after that you need to do the +f to the q
Hope this helps
Using the literal equation a-f = q, the solution for a = p + q
What is literal equation?A literal equation are type of equations which have two or more unknown variables . A literal equation can be solved by adding or subtracting or multiplying or divide by same numbers to the both sides of the equation in order to solve the expression for the required variable.
For example if an given equation is x+ y =2 and we want to solve it for y
Then we will try to keep y on one side and take remaining terms to other side.⇒ y = x-2 is solution for y.
Given equation :
a- f = q
To solve for a, add f to both sides
⇒ a- f + f = q+ f
⇒ a = q + f
Solution for a is q +f.

As an estimation we are told £3 is €4.
Convert €20 to pounds.
Answer:
£15

Set up a proportion, where x is €20 in pounds
[tex]\frac{3}{4}[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x:
4x = 60
x = 15

A square has an area of 200 square feet. Between what two consecutive integers would the
length of each side fall?
HELP ME PLEASE
Answer:
14 & 15
Step-by-step explanation:
The area of the square is given by the equation: [tex]A = s^2[/tex] so therefore the length of the side is: [tex]s = \sqrt{A}[/tex].
So we take [tex]s = \sqrt{200} = 14.14[/tex]
And this is between the integers 14 and 15.

what are the steps for solving -4+2x=5-(x-3)+3x
Answer:
I Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Step-by-step explanation:
Simplify
-4 + 2x = 5 + -1(x + -3) + 3x
Reorder your terms
-4 + 2x = 5 + -1(-3 + x) + 3x
-4 + 2x = 5 + (-3 * -1 + x * -1) + 3x
-4 + 2x = 5 + (3 + -1x) + 3x
Combine your like terms 5 + 3 = 8
-4 + 2x = 8 + -1x + 3x
Combineyour like terms -1x + 3x = 2x
-4 + 2x = 8 + 2x
Add -2x to each side of your equation.
-4 + 2x + -2x = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 + 0 = 8 + 2x + -2x
-4 = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 = 8 + 0
-4 = 8
Solving
-4 = 8

if we have a geometric series with u1 = 2.1 and r= 1.06, what would the least value of n be such that Sn > 5543?
Answer:
88
Step-by-step explanation:
Write the expression for the sum in the relation you want.
Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)
Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)
The relation we want is ...
Sn > 5543
35(1.06^n -1) > 5543 . . . . substitute for Sn
1.06^n -1 > 5543/35 . . . . divide by 35
1.06^n > 5578/35 . . . . . . add 1
n·log(1.06) > log(5578/35) . . . take the log
n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n
The least value of n such that Sn > 5543 is 88.
