Answer:
Yes, if you keep all of this in mind... This all came from my lesson during class btw.
Step-by-step explanation:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph. When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Answer: Choice D) [tex]y = \pm \sqrt{x+5}[/tex]
The steps to finding the inverse will have us swap x and y. Afterward, we solve for y
[tex]y = x^2 - 5 \\\\x = y^2 - 5 \\\\x+5 = y^2 \\\\y^2 = x+5 \\\\y = \pm \sqrt{x+5} \\\\[/tex]
------------------------------
Extra info:
The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into [tex]y = \pm \sqrt{x+5}[/tex] leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on [tex]y = x^2-5[/tex] to make it a one-to-one function, to make the inverse a function. One possible domain restriction is [tex]x > 0[/tex] which would lead to the inverse function [tex]y = \sqrt{x+5}[/tex]

Answer:
the answer to your question is y = -30
Answer:
-30
-Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2y+5=-10
Step 2: Subtract 5 from both sides.
1/2y+5-5=-10-5
1/2y+-15
Step 3: Multiply both sides by 2.
2*(1/2y)=(2)*(-15)
y=-30

Step-by-step explanation: I plugged this into my calculator
Answer:
600
Step-by-step explanation:
Always do what is the parentheses first so -12*5= -60
Then multiply -10 and -60
A negative and a negative equal a positive
10 times 60 is 600

1. XW≅ZW 1. Given It's good to start with given
2.∠XWY ≅ ∠ZWY 2. Given Again, get the given out of the way
3.WY ≅ WY 3. Reflexive This reason basically means that the line is equal to itself
4.ΔXWY ≅ZWY 4. SAS We have a side, an angle and a side: SAS
Second Problem
Again, let's get the givens out of the way. I'm lazy, so just put the things in the given section in the boxes.
3. Vertical angles This is just a fun way of saying that the angles on top of each other are equal
4. AAS We have an angle, an angle and a side. Whack em' together and you get AAS

-6a +3 =-3(2a-1) question number 2
Answer:
D. identity
Step-by-step explanation:
- 6a + 3 = - 3(2a - 1)
First, distribute -3 within the parenthesis.
- 6a + 3 = - 6a + 3
Subtract 3 from both sides of the equation
- 6a = - 6a
Divide - 6 on both sides of the equation
a = a
We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity
For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.
I hope that this helps! :)

m= -7 and b= 6
equation equals -13
Answer:
ok the slope is -1/2
the points I used where (-6,-1) and (-2,-3)
the intercept of y is -4
the equation is 2y +x+8=0
Step-by-step explanation:
using the formula y2- y1 = m
X2-X1
where m is the gradient, the slope is found
the original equation is y=-1/2x-4
and so if x is zero ( to get the y intercept)
y=-4
using the formula y - y1= m( x -x1 )
, the equation is determined

4(2x-1)+3(2x+5)
4(2x - 1) + 3(2x+5)
Answer:
14x + 1
Step-by-step explanation:
4(2x-1)+3(2x+5) = 2x*4 - 1*4 + 2x*3 + 5*3
= 8x - 4 + 6x + 5
= 8x + 6x -4 + 5 {Combine like terms}
= 14x + 1
A company announces that it will be giving $4,200 of its profits to charity. If the company profits 28,000 what percent will the company give to charity
Given:
Company profits = $28,000
Charity = $4200
To find:
The percent that will the company give to charity.
Solution:
We have,
Company profits = $28,000
Charity = $4200
Now,
[tex]Charity\%=\dfrac{Charity}{Profit}\times 100[/tex]
[tex]Charity\%=\dfrac{4200}{28000}\times 100[/tex]
[tex]Charity\%=\dfrac{420}{28}\times 1[/tex]
[tex]Charity\%=15\%[/tex]
Therefore, the company will give 15% of its profit to charity.
