Step-by-step explanation:
A. 4(a + 1) = 2
= 4a + 4 = 2
= 4a = 2-4 = - 2
= a = - 2/ 4 = - 1/2
B. 3 - 9x = - 6-8x
3 + 6 = - 8x +9x
9 = x
C. 12x - 3 = 14x - 35
- 3 + 35 = 14x - 12x
32 = 2x
32 / 2 = x
16 = x
You cannot subtract a number from a unknown. You’d simply put (9-b) in its place.
Answer:
amount = 407 per month
Step-by-step explanation:
given data
future value = $5000
interest rate = 6% =
= 0.015
time = 12 months = 4 compound per year
solution
we use here formula that is
amount = future value ×
.......................1
put here value and we get
amount = 5000 ×
amount = 1222 per quarter
or amount = 407 per month
Answer:
A function of the form
, where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
Step-by-step explanation:
A linear function is one in which the
value of the function varies linearly with 'x'. When we plot a linear function on a graph, the resulting curve is always a straight line with the slope of the line being constant.
A linear function is of the form:
, where, 'm' and 'b' are real numbers.
The degree or the highest exponent of 'x' in a linear function is always equal to 1.
Therefore, a function of the form
, where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
