Answer:
8x+7y^2
Step-by-step explanation:
Step-by-step explanation:
as we have a point and the slope, we can start with the point-slope form and then transform.
the point-slope form is
y - y1 = a(x - x1)
(x1, y1) being a point on the line, a being the slope.
the slope-interceot form is
y = ax + b
a being the slope again, b being the y-intercept (the y value for x = 0).
so, we have
y - -5 = 5/2 × (x - -4)
y + 5 = 5/2 × (x + 4) = 5x/2 + 5×4/2 = 5x/2 + 10
y = 5x/2 + 5
or
y = (5/2)x + 5
and this is already the slope-intercept form. all done.
Answer:
14.5 × 3.18 - 14.5 x 1.88
You paid $18.85 more in june than in February
Step-by-step explanation:
In order to find the answer to this question you will need to find how much you paid in June and how much you paid in February.
ex.14.5 x 3.18 - 14.5 x 1.88
To solve this you need to find the product of 14.5 x 3.18 and 14.5 x 1.88 and then subtract them from eachother.
ex.14.5 x 3.18 =46.11
14.5 x 1.88=27.26
46.11-27.26=18.85
