Answer:
Principal = $975
Step-by-step explanation:
Formula for interest is;
I = PRT/100
Where;
P is principal
R is interest rate
T is time
We are given;
I = $195
R = 4%
T = 5 years
Thus, making P the subject of the formula, we have;
P = 100I/RT
P = (100 * 195)/(4 * 5)
P = $975
Points (4,2) and (6, 10)
Eqn:
y - y = m(x - x)
y - 2 = [(2-10)/(4-6)] (x - 4)
y - 2 = (-8/-2) (x - 4)
y - 2 = 4(x-4)
y - 2 = 4x - 16
y - 2 + 2 = 4x - 16 + 2
y = 4x - 14
Therefore the slope (m) would be 4 and the y intercept (b) would be -14.
Answer: c= 49/4
Step-by-step explanation:
i thimk this might be the answer to question 3 (iii)
I'm sorry I don't know how to solve the first question
Answer:
(4,11)
Step-by-step explanation:
y=2x+3
y=5x-9
the first equation is equal to the second equation so
2x+3=5x-9
put like terms together
2x-5x= -9-3
-3x= -12
divide both sides by -3
.•.x=4
now, use the value of x to find the value of y like this:
y=2x+3 (x=4)
y=2(4)+3
y=8+3
y=11
therefore, the two lines intersect at the point (4,11)
