Expression: 2m + 2.50

Step-by-step explanation:

This is the expression that shows the total cost of Jose's trip.

The "2m" is because he has to pay $2 per each mile (m) he travels. The "+ 2.50" is because Jose has to pay $2.50 for the flag fall as well.

Hope it helps!

Immediate help ASAP whats the value of f(8)

77julia77 [94]

Answer:

$\large \boxed{f(8) = 27}$

Step-by-step explanation:

Goal

Find f(8)

Given

Equation

$f(x) = \frac{1}{2} {x}^{2} - ( \frac{1}{4} x + 3)$

Step 1

Substitute x = 8 in the equation and replace f(x) with f(8).

$f(8) = \frac{1}{2} {(8)}^{2} - ( \frac{1}{4} (8) + 3)$

Step 2

Evaluate the value of f(8).

$f(8) = \frac{1}{2} (64) - ( \frac{8}{4} + 3) \\ f(8) = 32 - ( \frac{2}{1} + 3) \\ f(8) = 32 - (2 + 3) \\ f(8) = 32 - (5) \longrightarrow 32 - 5 \\ f(8) = 27$

Hence, the value of f(8) is 27.

Let T:R²->R² be a linear transformation ,and assume that T (1,2)=(-1,1) and T(1,-1)=(2,3)

zavuch27 [327]

Answer:

(-4,-1)

Step-by-step explanation:

We are given T(1,2)=(-1,1) and T(1,-1)=(2,3) and T is a linear transformation.

This implies for scalars a and b that

T(a(1,2)+b(-1,1))=aT(1,2)+bT(-1,1)

T((a,2a)+(-b,b))=a(-1,1)+b(2,3)

T((a-b,2a+b))=(-a,a)+(2b,3b)

T((a-b,2a+b))=(-a+2b,a+3b)

This means we should be able to solve the system below to find a and b for T(3,3):

a-b=3 and 2a+b=3

Add equations to eliminate b and solve for a:

3a=6

Divide 3 on both sides:

a=2

If a-b=3 and a=2, then b=-1.

Plug in a=2, b=-1:

T((a-b,2a+b))=(-a+2b,a+3b)

T((2--1,2×2+-1)=(-2+2×-1,2+3×-1)

T(3,3)=(-4,-1).

Answer:

area = x^2 - 4x

Step-by-step explanation:

a = x(x-4)

a = x^2 - 4x (x times x is x^2, x times -4 is -4x)
