Answer:
25
Step-by-step explanation:
If it gives a result of -4 then our equation will have .... = -4
If we subtract 9 from the quotient of a number and 5 we have x/5 - 9
Our equation is:
x/5 - 9 = -4 add 9 to both sides
x/5 = -4 + 9
x/5 = 5 multiply both sides by 5
x = 5(5)
x = 25
Check: 25/5 - 9 = 5-9 = -4
Answer checks as correct from information given
Answer:
a
Step-by-step explanation:
Answer: Not possible
Step-by-step explanation: A whole number is an integer or a number without fractions. Both 15% and 40% are less than 1 since they are less than 100%; therefore, it is impossible to express them as whole numbers. They can only be expressed as the mixed numbers of 0.15 and 0.4, or 15/100 and 40/100.
Y = 4x + 5
slope = 4
perpendicular, slope = - 1/4
passing thru (8,3)
equation
y - 3 = -1/4 (x - 8)
y - 3 = -1/4x + 2
y = -1/4x +5
answer is D. y = -1/4x +5
