find the slope
(11, 7) and crosses the
y-axis of 17
Answer:
Slope of the line (m): -0.909090909091
Y-intercept of the line (b): 17.0
Slope Intercept Form (y = mx + b): y = -0.909090909091x + 17
Step-by-step explanation:
We have that the the slope (11, 7) and crosses the y-axis of 17 is
m=−0.909
From the question we are told
The the slope (11, 7) and crosses the y-axis of 17
Generally the equation for the Slope is mathematically given as
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\ Where\\\\\ Therefore\\\\m=\frac{17-7}{0-11}\\\\ m=-0.909[/tex]
Therefore

Greg spent 6.4 hours working with his dad one Saturday. If his dad paid him$45.76, how much did Greg make per hour?
Answer:
$7.15
Step-by-step explanation:
The best way to solve this is by crossing out the data you don't need so you're left looking at the key pieces to put the equation together. If his dad paid him $45.76 for 6.4 hours, then all you need to do is divide 45.76 by 6.4. (Hint: Use a calculator, it makes it ten times faster than trying to write it out!)
45.76 ÷ 6.4 = 7.15
So Greg made $7.15 an hour working with his dad.
Can some one help me find x?
Answer:
x = 20
Step-by-step explanation:
Exterior angles are equal.
7x - 3 = 6x + 17
Add 3 and subtract 6x to both sides.
x = 20 is the answer.

A parabola can be drawn given a focus of (5, -7) and a directrix of x=1. Write the equation of the parabola in any form.
Answer:
x = 1/8(y^2 + 14y + 73)
Step-by-step explanation:
Take any point on the curve (x, y). This is a parabola that opens to the right and contains terms in x and y^2.
The distance of this point from the focus = its distance from the directrix, so:
sqrt [( x - 5)^2 + (y + 7)^2) = (x - 1)
Squaring both sides:
(x - 5)^2 + (y + 7)^2 = (x - 1)^2
x^2 -10x + 25 + y^2 + 14y + 49 = x^2 - 2x + 1
y^2 + 14y + 73 = 8x
x = 1/8(y^2 + 14y + 73)

Suppose that 8 cards are drawn from a well-shuffled deck of 52 cards. What is the probability that all 8 are black? The probability is (Round to six decimal places as needed.)
Answer:
0.0020760077
Step-by-step explanation:
The probability of drawing the first black card is 26/52 because there are 26 of them in a deck of 52.
The probability of drawing the second black card is 25/51 because there are 25 of them in a deck of 51.
The probability of drawing the third black card is 24/50 because there are 24 of them in a deck of 50.
And so on and so forth, now we just have to multiply the 8 fractions together:
26/52*25/51*24/50*23/49*22/48*21/47*20/46*19/45=
[tex]\frac{26}{52} *\frac{25}{51} *\frac{24}{50}* \frac{23}{49} *\frac{22}{48} *\frac{21}{47} * \frac{20}{46} * \frac{19}{45}[/tex]= 0.0020760077

Answer:
B. 34º
Step-by-step explanation:
So we know that a straight line is equal to 180º and we already have to measure of angle 2. So to find the angle of measure 1, we just subtract 146 from 180.
180 - 146 = 34
So the measure of angle 1 is 34º.
Now, because of alternate exterior angles, we know that they would be the same. SO m∠7 = 34º
which is the equation of this best line of fit?
Answer:
D) y = 5x + 25
Step-by-step explanation:
the line of fit is defined by y = mx + b where:
m = the slope of the line (the rate of change)
b = the y-intercept (where it crosses the y-axis)
We see that for every 1 unit the graph moves horizontally... it moves 5 units vertically, thus we are given m = 5
If you look at the y-axis... we can determine that the graph crosses the y-axis at (0, 25), thus we are given b = 25
Therefore, the answer is y = 5x + 25
