The equation C = 0.20x + 50 gives the cost C in dollars for renting a truck and

k0ka [10]

Answer:

0.20 dollars/mile

Step-by-step explanation:

The slope actually has units. It has the meaning of 20 cents per mile. The units are cents per mile.

But it can also be 0.20 dollars/mile which is probably the way you should interpret it in a math class. That way it matches the units of the 50 which is for certain in dollars.

A triangle with the coordinates X(3, 2), Y(5, -1), and Z(-2, 3) is reflected across both the x- and y-axes. The coordinates afte

nata0808 [166]

Answer:

The coordinates of the reflected triangle are $X'(x,y) = (-3,-2)$ , $Y' (x,y) = (-5,1)$ and $Z'(x,y) = (2,-3)$ .

Step-by-step explanation:

Let be a point $(a,b)\in\mathbb{R}^{2}$ , reflections across x- and y-axes are represented by the following operations:

x-Axis reflection:

$d = d'$

$b - 0 = 0 - b'$

$b' = -b$

y-Axis reflection:

$d = d'$

$a - 0 = 0 - a'$

$a' = -a$

If we know that $X (x,y) = (3,2)$ , $Y(x,y) = (5,-1)$ and $Z (x,y) = (-2, 3)$ , the coordinates after both reflections are, respectively:

$X'(x,y) = (-3,-2)$

$Y' (x,y) = (-5,1)$

$Z'(x,y) = (2,-3)$

The coordinates of the reflected triangle are $X'(x,y) = (-3,-2)$ , $Y' (x,y) = (-5,1)$ and $Z'(x,y) = (2,-3)$ .

If ED = x + 4 and DB = 3x - 8, find ED, DB, and EB

Tom [10]

Answer:

Part 1) $ED=10\ units$

Part 2) $DB=10\ units$

Part 3) $EB=20\ units$

Step-by-step explanation:

we know that

EB=ED+DB

ED=DB -----> given problem

Substitute the given values and solve for x

$x+4=3x-8$

$3x-x=4+8$

$2x=12$

$x=6$

Find the value of ED

$ED=x+4$

substitute the value of x

$ED=6+4=10\ units$

Find the value of DB

Remember that

ED=DB

therefore

$DB=10\ units$

Find the value of EB

EB=ED+DB

$EB=10+10=20\ units$
