Answer:

2 ft³

Step-by-step explanation:

The volume (V) of the triangular pyramid is calculated as

V = $\frac{1}{3}$ Ah ( A is the area of the base and h the perpendicular height )

A = $\frac{1}{2}$ × 2 × 2 = 2 ft² ← area of triangular base and h = 3, thus

V = $\frac{1}{3}$ × 2 × 3 = 2 ft³

Solve the following system of equations by graphing and select the correct answer below:

JulijaS [17]

Answer: option c

Step-by-step explanation:

Find the x-intercept and y-intercept of each line.

To find the x-intercept, substitute $y=0$ into the equation and solve for "x".

To find the y-intercept, substitute $x=0$ into the equation and solve for "y".

- For the first equation:

x-intercept

$4x + 3y = 29\\\\4x + 3(0)= 29\\\\4x=29\\\\x=\frac{29}{4}\\\\x=7.25$

y-intercept

$4x + 3y = 29\\\\4(0) + 3y = 29\\\\3y=29\\\\y=\frac{29}{3}\\\\y=9.66$

Graph a line that passes through the points (7.25, 0) and (0, 9.66)

- For the second equation:

x-intercept

$2x - 3y = 1 \\\\2x - 3(0) = 1 \\\\2x=1\\\\x=0.5$

y-intercept

$2x - 3y = 1\\\\2(0) - 3y = 1\\\\-3y=1\\\\y=-0.33$

Graph a line that passes through the points (0.5, 0) and (0, -0.33)

Observe the graph attached. You can see that point of intersection of the lines is (5,3); then this is the solution of the system. Therefore:

$x=5\\y=3$

Write the equations after translating the graph of y = | 1/2x−2|+3, one unit to the right

AveGali [126]

$y=|\dfrac{1}{2}x-2|+3$

Since we are translating this graph one unit to the right, replace x with (x-1)

Note: If you are translating a graph to the left by k units, replace x with (x+k), and if by the right, replace x with (x-k)

$y=|\dfrac{1}{2}(x-1)-2|+3$

After simplifying, we now have the following equation:

$=|\dfrac{1}{2}x-\dfrac{5}{2}|+3$

This is the new equation. Let me know if you need any clarifications, thanks!

PLEASE HELP

Answer: 7

Step-by-step explanation:

1. multiply both sides by -6 so the -6 on the right side could cancel out and the left side would be -6: 1= a-13/-6 ==> -6=a-13

2. add both sides by 13 so -13 on the right side could cancel out and the left side would be -6+13: -6=a-13 ==> -6+13=a-13+13

3. you know -6+13 equals 7 right? so the answer is a=7
