(05.02)<br> A line passes through (2, 8) and (4, 12). Which equation best represents the line?

trapecia [35]

We can use the points (2, 8) and (4, 12) to solve.

Slope formula: y2-y1/x2-x1

= 12-8/4-2

= 4/2

= 2

Based on the question, we need to put the equation in slope-intercept form (y = mx + b).

Let's solve for the y-intercept. (We can use the point 2, 8 to solve).

y = 2x + b

8 = 2(2) + b

8 = 4 + b

8 - 4 = 4 + b - 4

4 = b

Now, that we know what the slope and y-intercept is we can put this into the final equation.

y = 2x + 4 (third option)

Best of Luck!

Hector had 30 minutes to do a three-problem quiz. He spent 11 3 4 minutes on question A and 6 1 2 minutes on question B. How muc

stich3 [128]

Answer:

$11 \frac{3}{4}$ min

Step-by-step explanation:

In order to solve this problem, we must subtract the times he has already used from the time he has available, so we get:

$30-11 \frac{3}{4} - 6 \frac{1}{2}$

we can start solving this subtraction by turning all of the numbers into improper fractions so we get:

$\frac{30}{1}-\frac{11*4+3}{4}- \frac{6*2+1}{2}$

$\frac{30}{1}-\frac{47}{4}- \frac{13}{2}$

next, we can find a least common denominator. In this case it will be 4, so we need to turn all denominators into a 4, so we get:

$\frac{30*4}{1*4}-\frac{47}{4}- \frac{13*2}{2*2}$

$\frac{120}{4}-\frac{47}{4}- \frac{26}{4}$

and now we can subtract the numerators and copy the denominators so we get:

$\frac{120-47-26}{4}$

$\frac{47}{4}$

which can now be turned into a mixed number by dividing 47/4 which yields 11 with a remainder of 3, so the mixed number is:

$11 \frac{3}{4}$ min

and this is the amount of time he has available to solve the las problem.

What is the volume of the prism

MakcuM [25]

From the graph , we have to find the length, width and height of the prism to calculate volume .

And for that we have to use distance formula.

$Length= \sqrt{(4-4)^2 +(6-0)^2 + (0-0)^2 } = \sqrt{36} =6 \\ Width = \sqrt{(4-0)^2+(6-6)^2+(0-0)^2} = \sqrt{16}=4 \\height = \sqrt{(4-4)^2 +(6-6)^2 +(2-0)^2 } = \sqrt{4} =2$

And the formula of volume is

$Volume = length * width * height = 6*4*2=48 \ cubic \ units$
