Answer:
(a) -20 1/2
Step-by-step explanation:
The proportion can be solved using "cross multiply" as the first step. This eliminates the fractions and turns it into a linear equation.
2/7 = -5/(x +3) . . . . . given
2(x +3) = -35 . . . . . . multiply by 7(x +3)
2x = -41 . . . . . . . . . simplify, subtract 6
x = -20 1/2 . . . . . . divide by 2
Hi there
To find the simple interest earned
Use this formula
I=prt
I interest earned?
P principle 30000
R interest rate 0.05
T time 15 years
So
I=30,000×0.05×15
I=22,500
Hope it helps

Answer:
y -2 = -2/3(x +4)
Step-by-step explanation:
There are several different forms of the equation for a line. Each is useful in its own way. Here, the line crosses the y-axis at a point between integer values, so using that intercept point could be problematical. That suggests the "point-slope" form of the equation for a line would be a better choice.
That form is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
__
The two marked points are (-4, 2) and (5, -4). All we need is the slope.
The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1) . . . . . . . . where the given points are (x1, y1) and (x2, y2)
m = (-4 -2)/(5 -(-4)) = -6/9 = -2/3
Using the first point, the equation for the line can now be written as ...
y -2 = -2/3(x -(-4))
y -2 = -2/3(x +4)
D. Seems like the right answer to me as far as I know
