The equation of line q is y =

1 answer:

3 0

These are not the exact numbers but just plug in the numbers of yours Because we know that q is a perpendicular line to p we know that its slope is the negative reciprocal of the slope of p. So its slope is 7/10. Now we just need to find its y-intercept. To do that we write what we know about line q. So we know that the equation for line q looks like:

y = (7/10)x + b

We also know that q passes through the point (8,7), so we now plug that in and solve for b:

7 = (7/10)(8) + b
7 - (56/10) = b
(70/10) - (56/10) = b
14/10 = 7/5 = b

So now that we have solved for the y-intercept, we know that the equation for line q is:

y = (7/10)x + 7/5

A drama club made $3,200 from a school play. Seventy-five percent of that amount came from ticket sales. Identify the values of

aev [14]

Answer: $2400

Step-by-step explanation:

Based on the question above, a will be the percentage of tickets that were sold while b will be tickwt sales. Therefore,

a = 75%

b = 75% × $3,200

= 0.75 × $3200.

= $2400

Based on the information above, the amount of tickets sales is $2400

Suppose a certain character in a role-playing game has an ability to use in battles. When activated, the ability deals damage to

Helen [10]

Answer:

The chance of getting exactly 3 hits is = 0.20

Step-by-step explanation:

P.S - The exact question is -

As given,

F(x) = 0 , x < 1

0.30 , 1 ≤ x < 2

0.56 , 2 ≤ x < 3

0.76 , 3 ≤ x < 4

0.9 , 4 ≤ x < 5

1 , 5 ≤ x

Now,

f(x) = 0.30 , x = 1

0.56 - 0.30 = 0.26 , x = 2

0.76 - 0.56 = 0.20 , x=3

0.9 - 0.76 = 0.14 , x = 4

1 - 0.9 = 0.1 , x = 5

0, otherwise

Now,

The chance of getting exactly 3 hits is = f(x = 3) = 0.20

Which of the following point-slope form equations could be produced with the points (-1, 4) and (2, -3)?

Nikolay [14]

Answer:

Option B, y + 3 = -7/3(x - 2)

Step-by-step explanation:

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

Step 1: Find the slope

m = $\frac{y2 - y1}{x2 - x1}$

m = $\frac{-3 - 4}{2 - (-1)}$

m = $\frac{-7}{2 + 1}$

m = $\frac{-7}{3}$

Step 2: Plug into the point slope form

(y - 4) = -7/3(x - (-1))

(y - 4) = -7/3(x + 1)

(y - (-3)) = -7/3(x - 2)

y + 3 = -7/3(x - 2)

Answer: Option B, y + 3 = -7/3(x - 2)
