How many solutions does this system of equations
have?

Infinite
None
One

Answers

Answer:

Step-by-step explanation:

None

The hint is in the slopes which is the number in front of x. Both equations have a slope of 1/2

The y intercepts are different (4 for the top one 2 for the bottom one). That tells you that you have two lines and not one of top of the other. These two lines never meet, because the slopes are the same. Therefore there are no values that both lines have in common.

That makes the answer none.

Cube A has a volume of 9 in3. Cube B has a volume of 5 in3. Which of the following expresses the ratio of the side length of Cube A to the side length of Cube B?

(A) 3 : 5 ^1/3
(B) 5^1/3 : 3^1/3
(C) 3^1/3 : 5^2/3
(D) 3^1/3 : 5^1/3
(E) 3^2/3 : 5^1/3

Answers

Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:

[tex]r = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}[/tex]

Which means that option E is correct.

The volume of a cube of side length l is given by:

[tex]V = l^3[/tex]

For Cube A, the volume is of 9 cubic inches, hence:

[tex]l_a^3 = 9[/tex]

[tex]l_a = \sqrt[3]{9}[/tex]

[tex]l_a = 9^{\frac{1}{3}}[/tex]

[tex]l_a = 3^{\frac{2}{3}}[/tex]

For Cube B, the volume is of 5 cubic inches, hence:

[tex]l_b^3 = 5[/tex]

[tex]l_b = \sqrt[3]{5}[/tex]

[tex]l_b = 5^{\frac{1}{3}}[/tex]

Then, the ratio is:

[tex]r = \frac{l_a}{l_b} = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}[/tex]

Write an equation in point-slope form of the line that passes through the point (−3,6) and has a slope of 5.

Answers

Answer:

Below in bold.

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1)

where m = the slope of the line and (x1, y1) is a point on the line.

Here m = 5, x1 = -3 and y1 = 6.

So we have:

y - 6 = 5( x - (-3))

y - 6 = 5(x + 3)   (Answer)
