[tex]\huge\boxed{\sf C.}[/tex]

Step-by-step explanation:

Slope 1 = 2 / 3

Slope 2 = -3/2

Multiplication of slopes:

= [tex]\sf \frac{2}{3} * \frac{-3}{2}[/tex]

= -1

Multiplication of these slopes have a result of -1. This means that the two lines are perpendicular.

There are 6 flavors of candy in a bag. The probability of randomly selecting strawberry is 1/4, lime is 3/16, cherry is 1/8, and grape is 14/64. The rest of the candy is orange. What is the probability of randomly selecting a piece of orange flavored candy?

Answers

The answer is 3/8. You can find a common denominator of 64 among all of the fractions. From this, you can find how many orange candies there are. There is 64 candies, and 40 of them are other flavors, so there's 24 orange candies. You can create the fraction 24/64 and simplify it down to 3/8.
The correct answer is 3/8. I hope this helps! And ik this because i did the math

Jenna can swim 150 meters in 3 minutes. If you graph this with minutes on the X-axis and meters on the Y-axis, what will be the slope of the line? Which of the following are increased in concentration in a basic solution

Answers

The equation of a line is y = 50x. Then the slope of the line is 50 meters per minute.

What is the slope?

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Jenna can swim 150 meters in 3 minutes.

If you graph this with minutes on the X-axis and meters on the Y-axis.

Then the slope of the line will be

m = 150 / 3

m = 50 mters per minute

Then the equation will be

y = 50x

Ms. Gartland bought x number of shirts for the new members of her chorus. The cost for x number of shirts including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on the purchase. What equation could be used to find x.

A - 3.99(x + 12.25) = 77.49

B - 3.99x + 12.25 = 77.49

C - 12.25(x + 3.99) = 77.49

D - 12.25x + 3.99 = 77.49

Answers

Answer: The answer would be

D - 12.25x + 3.99 = 77.49

Step-by-step explanation:

If each shirt costs $12.25, that would be 12.25 times “x” amount of shirts. Then, you add the $3.99 shipping amount. Which all equals 77.49.

I am pretty sure B is correct answer

Answer:

A. Slope is -5. Y-intercept is (0,7)

Step-by-step explanation:

1. Find the slope using the slope formula and the coordinates

Remember, the slope formula is: y2-y1/x2-x1

You'll use the coordinates (0,7) (4, -13) to plug into the formula.

-13-7/4-0

= -20/4

= -5

Slope is -5

2. Find the y-intercept.

First, write the equation of the line in point-slope form: y-y1=m(x-x1)

M is slope and y1 and x1 can be from any ordered pair (as long as they're from the same one). Let's use (0,7)

y-7=-5(x-0)

Simplify the equation.

y-7=-5x+0

y=-5x+7

3. Now the equation is in y-intercept form, or y=mx+b. Again, M is slope. B is the y intercept. So, the y-intercept is 7

Y=2x+5 is greater than the rate of change of the function represented in the graph. To find this, first remember that rate of change is just slope. This means that you can easily find the slope of the already given function y=2x+5, which is just 2. Then you take two pairs from your table. I took -1,0 and 2,3. You then place those into the equation used to find slope, y2-y1 over x2-x1. 3-0 equals 3 and 2-(-1), which means 2+1, since you’re subtraction a negative number is also 3, meaning your slope or rate of change is 1. 1 is a smaller number than 2 and therefore the rate of change in the already given function is greater than that of the table. Hope this helps!
