What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (−3, 1)?
puteri [66]

Answer: The answer is (D) y-1=\dfrac{3}{2}(x+3).

Step-by-step explanation:  We are given to find the equation of a line which is parallel to the line in the graph and passing through the point (-3, 1).

The points (-2, -4) and (2, 2) lie on the line in the graph, so its slope will be

m=\dfrac{2+4}{2+2}=\dfrac{6}{4}=\dfrac{3}{2}.

The slope of the line parallel to the line in the graph will also be same. Since the new line passes through the point (-3, 1), so the equation of the line will be

y=1=m(x+3)\\\\\Rightarrow y-1=\dfrac{3}{2}(x+3),

which is in the slope-intercept form.

Thus, the correct option is (D).

a $7,000 principal is invested in two accounts, one earning 3% interest and another earning 7% interest. if the total interest f
Ksju [112]

Let the investment in first account be x and this account is earning 3% interest

So Interest on this account is 3% of x = 0.03x

So the investment in second account would be (7000-x) and this account is earning 7% interest

So the interest on this account is 7% of (7000-x) = 0.07*(7000-x)

Given that total interest for the year is $262

So we have

0.03x + 0.07(7000-x) = 262

0.03x - 0.07x + 0.07*7000 = 262

-0,04x + 490 = 262

-0.04x = 262-490

-0.04x = - 228

0.04x = 228x

x = 228/0.04

x = 5700

Therefore Investment in one account s 5700 and the investment in other account is 7000-5700 = 1300
