Kevin plans to put concrete on a rectangular portion of his driveway the portion is 10 feet long and 3 inches high the price of

Fudgin [204]

First we need to know the total volume of concrete used:
$V_total = \frac{cost_{total}}{cost{unit}}$
$V_total = \frac{\$72.98}{\frac{\$90}{yd^{3}}}$
$V_total = 0.7407yd^{3}$

Now we can use the formula for volume of a rectangular prism:
$V=lwh$
Convert everythig to yards and substitute:
$0.7407yd^{3}=(3.33yd)(w)(0.08333yd)$
$w=\frac{0.7407}{3.33 \times 0.08333}$
$w \aprox 2.66yd$

Question 13 (4 points) (05.03) Which of the following statements best describes the graph of -5x + 2y = 1? (4 points)

alexandr1967 [171]

Answer:

C) straight line through (1, 3) ... (-3, -7)

Step-by-step explanation:

The linear equation will describe a straight line. The slope and general location of the line on a graph can be estimated from its x- and y-intercepts.

<h3>intercepts</h3>

The x-intercept is the value of x that satisfies the equation when y=0.

-5x +2·0 = 1

x = -1/5 . . . . . . divide by the coefficient of x

The y-intercept is the value of y that satisfies the equation when x=0.

-5·0 +2y = 1

y = 1/2 . . . . . . divide by the coefficient of y

<h3>nature of the graph</h3>

The intercept values mean the line crosses the positive y-axis and the negative x-axis. It will have a positive slope. Points on the line that have integer x- and y-coordinates will have coordinates that have the same sign.

Of the offered answer choices, A and B are eliminated because the graph is <em>not a curve</em>. D is eliminated because the suggested points have coordinates with <em>opposite signs</em>. The correct choice is C:

It is a straight line joining the points (1, 3), (3, 8), and (-3, -7)

If f(x) = |x| + 9 and g(x) = –6, which describes the value of (f + g)(x)?

Kryger [21]

(f+g) (x)= f(x) + g(f)

= IxI + 9 + (-6)

= IxI + 9 - 6

= IxI + 3

(f + g)(x) = IxI + 3
