Answer:
5
Step-by-step explanation:
Terrible wording on the question as the "father" is 15 the "son" is 10 and the sister is 0 or just born
J = john
S = son
X = sister
J = 2s
S = 5 + X
3(x+5) = J + 5
J = 2(5+x) = 2x + 10
3x+15 = 2x +10 + 5
x = 0
Answer:
the one that cost the most interest is option B.
Step-by-step explanation:
In order to select the one that costs more we need to apply the data from each one to the formula below:
M = C*r*t
Where M is the interest amount, C is the value of the loan, r is the interest rate and t is the time elapsed. We have:
A)
M = 1500*0.0625*(24/12) = 187.5
B)
M = 1500*0.06*(30/12) = 225
C)
M = 1500*0.04*(36/12) = 180
D)
M = 1500*0.0375*(42/12) = 196.875
Therefore the one that cost the most interest is option B.
Answer:
Step-by-step explanation:
a. the balloon is rising because the slope is positive. the slope is 40 because when you simplify y-160 = 40 (x-1) it gets you y = 40x +120
b. it is ascending (bc positive) at 40 feet per minute
c. it was at 120 feet in the air. The 120 is the y intercept
Answer:
The correct answer is C.
Step-by-step explanation:
The given equation is;
This implies that;
Let us write in Cartesian coordinates by substituting;
Square both sides;
This implies that;
This is an equation of a parabola that opens upwards with a y-intercept of 
.
The correct choice is C
