Answer:
y=-2x+4 (c)
Step-by-step explanation:
y=mx+b
m=slope
b= y-intercept
4a + 5a - 15 = 2 + 3a
6a = 17
a = 17/6
Answer/Explanation:

Without the expressions given, answer by referencing these steps.
4 = 4/1
When multiplying fractions, multiply both numerators and both denominators to get the answer.
In the answer, you may simplify if there are common factors in both the top and bottom number. In this case, 12 and 5 do not have a common factor and is already in the most simplified form.
Answer:
The standard form is: 
The function is of the 3rd degree.
The leading coefficient is 8.
The constant term is -3.
Step-by-step explanation:
Placing in standard form:
To place in standard form, we solve the operations. So




Degree:
The degree is given by the highest power of x, which, in this exercise, is 3.
Leading coefficient:
The leading coefficient is the term that multiplies the highest power of x. In this exercise, the higher power of x is
, which is multiplied by 8. So the leading coefficient is 8.
Constant term:
The constant term is the one which does not multiply a power of x. So in this exercise, it is -3.
Answer:
500
Step-by-step explanation:
10*1*22=220
7*4*10=280
220+280=500
