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
Given y=15x+4, write the equation of the line perpendicular to the given line that contains point (-2, 3). (10 points)
You must show all work neat and organized! No work! No credit! Final answer should be in slope-intercept form.

This question has far to little detail for someone to answer correctly, the person who got 22=11+n is just spiting out random stuff.
7n2 + 5 = 453
Solve the quadratic function
7n^2 + 5 = 453
Subtract 5 from both sides:
7n^2 = 448
Divide both sides by 7:
N^2 = 64
Take the square root of both sides:
N = 8

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.

solve x -5y = 6 for x
Answer:
x=5y+6
Step-by-step explanation:
Find the area and perimeter of a rectangle if the length is (x+7) and the width is (x+3).
[tex]\sf Length\:=\:(x+7) \\\\\sf
Breadth\:=\:(x+3) \\\\\sf
Area= Length\: x\: Breadth \\\\\sf
=(x+3)(x+7) \\\\\sf
=x^2+7x+3x+21 \\\\\sf
=x^2+10x+21 \\\\\sf
\boxed{Area=x^2+10x+21} \\\\ \\\\\sf
Now, \:Perimeter\:=\: 2x(length +breadth) \\\\\sf
=2(2x+10) \\\\\sf
=4x+20 \\\\\sf
\boxed{Perimeter=4x+20} [/tex]
[tex]l = (x + 3) \\ b = (x + 7)[/tex]
Area:
[tex] = l \times b \\ = (x + 3)(x + 7) \\ = x(x + 7) + 3(x + 7) \\ = {x}^{2} + 7x + 3x + 21 \\ = {x}^{2} + 10x + 21[/tex]
Perimeter:
[tex] = 2(l + b) \\ = 2((x + 3) + (x + 7)) \\ = 2(x + 3 + x + 7) \\ = 2(2x + 10) \\ = 4x + 20[/tex]

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.

Marlene decided to buy 2 bags of apples weighing 3 1/4 pounds each, instead of 3 bags weighing 2 2/5 pounds each. Did she end up with more apples or fewer apples by buying the bigger bags?
To find the total weight of 2 bags of apples weighing 3 and 1/4 pounds, multiply.
Answer Choices: 5 1/4, 5 1/2, 6 1/4, 6 1/2.
To find the total weight of 3 bags weighing 2 and 2/5 pounds, multiply.
Answer Choices: 5 2/5, 6 2/5, 7 1/5, 7 2/5.

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
64x3+729
=(4x+9)(16x2−36x+81)

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.
