Answer:
<h2>-x²+4x +6</h2>
Step-by-step explanation:
Given f(x)=4x+1 and g(x)=x²-5
(f-g)(x) is derived by taking the difference of both functions
(f-g)(x) = f(x)-g(x)
(f-g)(x) = 4x+1 - (x²-5)
(f-g)(x) = 4x+1-x²+5
(f-g)(x) = -x²+4x +6
This gives the requires expression
Answer:
>20 degrees
Step-by-step explanation:
Solution for the system of linear equations is (4, - 3)
<u>Step-by-step explanation:</u>
Step 1:
Given system of equations
x - 3y = 13 -------- (1)
2x + 4y = - 4 ----- (2)
Step 2:
Multiply eq(2) with 2 to make coefficients of x equal.
2x - 6y = 26 ------ (3)
Step 3:
Subtract eq(2) from eq(3)
⇒ - 10y = 30
⇒ y = -3
Step 4:
Find value of x by substituting value of y in eq(1)
⇒ x - 3 × (-3) = 13
⇒ x + 9 = 13
⇒ x = 4
Since he starts with (10x+7) dollars and is buying two pairs of jeans that each cost (4x-5) dollars you should subtract the cost of the jeans from his starting amount.
(10x+7)-2(4x-5)=
10x+7-8x+10=
2x+17
Answer:
How about asking your math teacher for help, instead of going to the internet? As your math teacher, I think it would be a better idea than having your teacher find your internet post!
