Answer:
y=-1/2+3
Step-by-step explanation:
first, we have to determine if the slope is positive or negative. if it is going up to the right, it is positive. if it goes up to the left, it is negative. to find the slope, we need two or three points where the x and y values are both whole numbers. for this, we can use the y-intercept (0,3), (-2,4), and (-4,5). we can look at the line and see that from (0,3) to (-2,4) the line rises 1 and runs -2. this supports the claim that the slope is negative. from (-2,4) to (-4,5), the line rises 1 and runs -2. this is the same as the slope from (0,3) to (-2,4), so we can say that it is the slope of the line. since slope is written as rise over run, we can write the slope as -1/2. for the y-intercept, or b, we have to see what y is when x is 0. y is 3, so the y intercept is 3. in y=mx+b, m=slope and b=y intercept, so we plug these values in and we have the graph in slope intercept form.

<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
The given equation is
900+50x=450+75x
To solve;
900 - 450 = -50x +75x
450 = 25x
x = 450 /25
x = 18

Answer:
½ or 11/10
Step-by-step explanation:
3/10 = 8/10 - X
X = 8/10 - 3/10 = 5/10 = 1/2
Or,
X - 8/10 = 3/10
X = 11/10
Answer:
$350
Step-by-step explanation:
If $280 is the 20% savings from the original price, it is 80% of original price.
280 / 0.8 = 350
From this equation, we can know that 350 is 100% of original price, which makes it the original price.
Hope this helps!
Well since we know that for one day Mrs. Fernandez drives 6 and 1/9 miles to work what could we do to get 12 days of work driven.
all we have to do here is multiply 12 and 6 and 1/9 :) lets set this up
1 1 12
6 ---- x 12 or lets set this up like this 6 ---- x -----
9 9 1
but lets change that whole fraction into an improper fraction
1
6 ---- so all we do is multiply 6 x 9 and add the 1 so lets try that
9
6 x 9 = 54
54 +1 = 55
hey look we have our numerator!! ( the top number)
and our bottom number would stay the same as 9 so lets try this again:)
55
----- now lets plug it in to our problem
9
55 12
----- x -----
9 1
now lets just multiply across
55 12 = 55 x 12 = 660
----- x -----
<span> 9 1 = 9 x 1 = 9
</span>
so now our fraction look like this
660
-------
9
but lets make it not look so confusing and divide 660 by 9
660/9 = 73.33333333
again it still looks confusing but we can round it out to beeeee
73
so this means that for 12 days Mrs. Fernandez drove 73 miles!
hope this isnt confusing;)
have a good one and mark me brainliest!
