Answer:
The equation is c=25h+30 and the answer is 205
Step-by-step explanation:
Plug in 7 for h.
Assume that the bank balance started at zero. Enter the income and outgo in chronological order: $300 - $50 - $75 + $225
Find the sum. This sum will represent the amount left in the account after the $225 deposit:
$250 - $75 + $225, or
$175 + $225 = $400 The final balance will be $400.
Answer:
y = 3/7x + 51
Step-by-step explanation:
y = 3/7x + 11 is parallel to the line so it means that both of their gradient are same so:
y = mx + c
m= gradient point = (-21 , 42)
= 3/7
now we sub the m and the point into the formula which is y= mx+c because we should find the c first then we can find the equation of the line:
42 = 3/7 (-21) + c
42 = -9 + c
42 + 9 = c
51 = c
c = 51
now you hv to rewrite again the equation become y= 3/7x + 51
So now your final answer is : y = 3/7x +51
Answer:
3.8
Step-by-step explanation:
Slope formula- m = y2 - y1
x2 - x1
x1, y1
2.1, 3.8
7.6 - 3.8
3.1 - 2.1 = 3.8
x2,y2
3.1, 7.6
