Given:
[tex]6x+3y=12[/tex]
[tex]2x-6y=18[/tex]
[tex]5x+2y=16[/tex]
[tex]6x-8y=-24[/tex]
To find:
The slope intercept form of each equation.
Solution:
We know that, slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
The first equation is
[tex]6x+3y=12[/tex]
Subtract 6x from both sides.
[tex]3y=12-6x[/tex]
Divide both sides by 3.
[tex]y=\dfrac{12-6x}{3}[/tex]
[tex]y=\dfrac{12}{3}-\dfrac{6x}{3}[/tex]
[tex]y=4-2x[/tex]
[tex]y=-2x+4[/tex]
Therefore, the slope intercept form of first equation is [tex]y=-2x+4[/tex].
Similarly,
[tex]2x-6y=18[/tex]
[tex]-6y=18-2x[/tex]
[tex]y=\dfrac{18-2x}{-6}[/tex]
[tex]y=-3+\dfrac{1}{3}x[/tex]
[tex]y=\dfrac{1}{3}x-3[/tex]
Therefore, the slope intercept form of second equation is [tex]y=\dfrac{1}{3}x-3[/tex].
[tex]5x+2y=16[/tex]
[tex]2y=16-5x[/tex]
[tex]y=\dfrac{16-5x}{2}[/tex]
[tex]y=8-\dfrac{5}{2}x[/tex]
[tex]y=-\dfrac{5}{2}x+8[/tex]
Therefore, the slope intercept form of third equation is [tex]y=-\dfrac{5}{2}x+8[/tex].
[tex]6x-8y=-24[/tex]
[tex]-8y=-24-6x[/tex]
[tex]y=\dfrac{-24-6x}{-8}[/tex]
[tex]y=\dfrac{-24}{-8}-\dfrac{6x}{-8}[/tex]
[tex]y=3+\dfrac{3}{4}x[/tex]
[tex]y=\dfrac{3}{4}x+3[/tex]
Therefore, the slope intercept form of fourth equation is [tex]y=\dfrac{3}{4}x+3[/tex].

A line passes through the point (2,3) and has a slope of -2. Which is the equation of the line in point-slope form?
Answer:
7-2x=y
Step-by-step explanation:
When a point passes through a line it satisfies its equation
(X-x0 )m= y-y0
Slope = m = -2
(X-2 )(-2)=y-3
4-2x=y-3
7-2x=y

Answer:
the answer is True (explanation below) your current answer is incorrect the equation does have No Solution.
Step-by-step explanation:
The equation has no solution because when you simplify the equation as much as possible, we are left with 2=-2. However, 2=-2 is not true, so there is no answer to this equation.

now you have -4x+2+3 add like terms
now you have -4x+5
[tex]\sf \longmapsto−4x+2+3[/tex]

Don't shame I'm just trying to pass, my assignment's weigh 35% of my grade, right now my assignment percentage is 65%. My test which holds 45% of my grade is at 85% and my final is 20%, which I got a 90 on. If I take 7 0's in assignments, what would my grade be? Basically asking how many 0's under assignments can I basically take so I do not fail. Hope this makes sense
Answer:
Step-by-step explanation:
Let's start by weighing everything but the assignments. We'll get back to them momentarily.
You have 85% on 45% of your grade. That's 38.25
Your final weighs in at 20%. You have. 18
So your total so far is 56.25
Now that looks mighty low, but we haven't put in the assignments yet.
So by the time you are finished you will have done 41 out of 48 assignments and that means you have done (41/48)*100 = 85.41 of the work. On these assignments that you have done, you averaged 65%
So your assignment mark will be 0.65 * 85.41 = 55.52
The weighted average = 0.35
The mark you will get is 0.35 * 55.52 = 19.32
So your final grade will be 56.25
Grade 75.57
In Canada (where I live), that would be a solid B. I don't know how things are calculated in the US, but I have done the work properly, I think.
What is the image of (−5,9) after a reflection over the y-axis?
Answer:
(5, 9 )
Step-by-step explanation:
Under a reflection in the y- axis

Suppose that F(x) = x^2 and G(x)=3x^2 +8. Which statement best compares
the graph of G(x) with the graph of F(x)?
* look at picture* please put right answer
Answer:
ur screwed go with b
Step-by-step explanation:
Answer:B The graph of g(x) is the graph of f(x) compressed vertically. The factor of compression is 2/5 and is less than 1 so it is compressed instead of stretch if the factor was greater than 1. There is no reflection across the x-axis because there is no negative sign in front of the function f(x).

Which property is shown in this example?
(6.3 + 5.2) + 8.7 = 6.3 + (5.2 + 8.7)
A. Identity Property
B. Commutative Property
C. Associative Property
D. Distributive Property
Answer:
associative property
Step-by-step explanation:
identity property is when you multiply one by any number and get the number you multiplied by. for example, 1x3=3; 1x7=7. Commutative property has to do with the order of multiplication being rearranged. and distributive property multiplies a number outside the parentheses into the numbers inside. all that's left is the associative property which indicates that addition can be rearranged and still get the same answer. hope this helps :)

i have to find the mean and range of this data set and show work.
data set: 49,50,52,58,61,63,66,67,67,68
Answer:
61 is the mean and the range is 19
Step-by-step explanation:
trust
Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given set of data.
What is Mean?
"Mean is the average set of all the given values."
What is Range?"Range is the difference between highest and the lowest value."
Formula
Mean = [tex]\frac{Sum of all the observations}{Total number of observations}[/tex]
Therefore, Mean = [tex]\frac{49 + 50 +52 +58 +61 +63 +66 +67 +67 +68}{10}[/tex]
= [tex]\frac{601}{10}[/tex]
= [tex]60.1[/tex]
Range = Max (x) - Min (x)
= [tex]68 - 49[/tex]
= [tex]19[/tex]
Hence, the Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given data set.

Answer:
RP = 2.3
PQ = 1.0
RQ = 2.3
Step-by-step explanation:
The pictures says RP = RQ,
so:
3x - 0.4 = x + 1.4
this you can simplify to:
x = 0.9
Then fill x in:
RP = 3*0.9 - 0.4 = 2.3
PQ = 0.9 + 0.1 = 1.0
RQ = 2.3
