Answer:
<h3>The answer is option C</h3>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(8, 10) and (-7, 14)
The slope is
We have the final answer as
Hope this helps you
Answer:
The answer is (-0.7, -9.4)
Step-by-step explanation:
1) Since we are using the substitution method, and we know that y = 2x-1, in the first equation, plug that into y. It should look like this:
4x-2(12x-1) = 14
4x -24x + 2 = 14
2) Combine like terms and continue to simplify until you get a direct answer for each variable.
-20x + 2 = 14.
-20x = 12.
x = -7/10 (or -0.7)
3) Now we know what x equals, so to find our y-coordinate, we will plug this into either equation.
y = 12(-7/10) -1
y= -84/10 -1
y= -9.4
4) Now that we have our x value and y value, we know our point. The solution is (-0.7, -9.4).
You would multiply by 1.2 for example if you wanted to find 120% of 100 you would multiply by 1.2 and get 120
Answer:
$140
Step-by-step explanation:
So to find the increased price, do 100*1.4=140
That's the answer. Another way to do it is 100*.4=40.
40+100=140
