Answer:
O y = (x + 5) (x + 3)
Step-by-step explanation:
y = (x + 4)² - 1
y = x² + 8x + 15
y = x² + 3x + 5x + 15
y = x(x + 3) + 5(x + 3)
y = (x + 5) (x + 3)
10 2/5 times 15 5/7 is 5,720/35 which is 163 15/32 in mixed number
Solution should have the same rate of change if it’s parallel
Answer <u>(assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line by using the slope formula,
. Substitute the x and y values of the given points into the formula and solve:
So, the slope is
.
2) Now, use the point-slope formula
to write the equation of the line in point-slope form. Substitute real values for the
,
, and
in the formula.
Since
represents the slope, substitute
in its place. Since
and
represent the x and y values of one point the line intersects, choose any one of the given points (either one is fine, it will equal the same thing at the end) and substitute its x and y values into the formula as well. (I chose (0, -7), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the following answer:
![y-(-7) = -\frac{5}{4} (x-(0))\\y + 7 = -\frac{5}{4} x\\y = -\frac{5}{4} x-7](https://tex.z-dn.net/?f=y-%28-7%29%20%3D%20-%5Cfrac%7B5%7D%7B4%7D%20%28x-%280%29%29%5C%5Cy%20%2B%207%20%3D%20-%5Cfrac%7B5%7D%7B4%7D%20x%5C%5Cy%20%3D%20-%5Cfrac%7B5%7D%7B4%7D%20x-7)
