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.

Answer:

y=(5x-3)/4

y=(5/4)x-3/4

Perpendicular slops come from reversing the numerator and denominator and making it negative so the new slope would be:

m=-4/5

Then you use point slope formula and plug in your values:

y-y1=m(x-x1)

y-1=-4/5(x-1)

y=(-4/5)x+9/5

Hope this helps you, have a night day/night.

Answer:

A

Step-by-step explanation:

Both triangles are similar triangles!

Length 21 for the top triangle is similar to length 20 for the bottom triangle

Length 29 for the top is similar to b on the bottom.

Length 20 for the top is similar to a on the bottom.

Use the first ratio: 21/20 to find the proportionality constant.

Divide 29 by that constant to get b

Divide 20 by that constant to get a

You end up with b = 580/21 (= 27.61), and a = 400/21 (= 19.047)

Therefore A is the right answer.

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:

1. 15x + 10y=-11

15x + 10y + 11=-11 + 11

15x + 10y + 11 = 0

2. -9x + DT = 19

-9x = 19 - DT

x = 19/9 + 1/9DT

x = 19/9 + 1/9DT, D∈ℝ, T∈ℝ

Answer: hmm..... –3 3/14

Step-by-step explanation:

Answer:189.75

Step-by-step explanation: 220 * 0.15 = 33

220 + 33 = 253

253 * 0.25 = 63.25

253 - 63.25 = 189.75

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)

Answer:

=3

Step-by-step explanation:

Simply, you need to find which number times 6 will give you -18, the answer is 3.

I hope this helps!

Answer:

-3 is the answer

Step-by-step explanation:6*3 =18 and there is already a positive number which is 6 so the negative must be three

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

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.

Answer:

30 students.

Step-by-step explanation:

Since 20 girls make up 4/6 of the class, 1/6 of the class would be 5 students. 5*6=30, resulting in 30 students total.

If you are trying to factor it is 14(3a+b).

But if you are looking for the greatest common factor it is 14.

The GCF of  42a + 14b is 14 which is 14(3a + b).

GCF stands for the greatest common factor of two or more two given terms. A number is GCF of two or more than two terms is the highest term that divides the given terms completely.

Given,  42a + 14b and we have to factor this with a GCF.

In terms of variables a and b, there is no common factor.

In terms of 14 and 42 GCF is 14 as 14 is the highest no. that divides these two nos. completely.

So, 42a + 14b.

= 14(3a + b).
