Answer:
answer is C
Step-by-step explanation:
A survey reported that out of 50 teenagers, 9 said they get their news from a newspaper.
To find the perpendicular line a y- 2 = 7/3 (x + 5) you must first observe that the slope is m = 7/3, therefore, the slope of the perpendicular line put of the reciprocal, that is, m = - 3/7. So the possible options are A or C, but since the point (-4, 9) must go through the line, we find that the equation that satisfies that is option C.Therefore the perpendicular line that passes through the point (-4, 9) is C. y - 9 = -3/7 (x + 4)
The present value of the loan will be = R36,250
<h3>Calculation of the present value</h3>
The principal capital (P) = R25 000
Interest rate for the payment (R)= 7.5%
Time for the payment (T)= 6 years
Therefore simple interest = P×T×R/100
= 25,000×6×7.5/100
= 250×6×7.5
= R11,250
The present value of the loan will be;
= 25,000 + 11,250
= R36,250

<span>product of a number and 10: 10n
</span><span>Seven less than the product of a number and 10: 10n - 7
so
</span><span>Seven less than the product of a number and 10 is 50:</span>
10n - 7 = 50
----------------------------
if you need to find the number n then
10n - 7 = 50
10n = 57
n = 57/10
n = 5.7
