Answer:

3

Step-by-step explanation:

In order to do this equation, your first step is to use the Order of Operations, or PEMDAS, which means that you multiply (M) two times two first before subtracting the equation (S). 2 times 2 is 4. 4 - 1 = 3. Hope I helped! :)

Angles CPD and BPA are vertical angles, meaning that they are equal. We see that angle CPA is equal to 60 degrees, therefore angle BPA is equal to 60 degrees.

The coordinates of A, B, and C in the diagram are A (p, 4), B (6, 1 ), and C (9, q). Which equation correctly relates p and q? ↔

aivan3 [116]

Answer:

D. p + q = 7

Step-by-step explanation:

The slope of AB is ...

mAB = (y2 -y1)/(x2 -x1) = (1 -4)/(6 -p) = -3/(6 -p)

The slope of BC is ...

mBC = (q -1)/(9 -6) = (q -1)/3

We want the product of these slopes to be -1:

mAB·mBC = -1 = (-3/(6 -p))·((q -1)/3)

-(q-1)/(6 -p) = -1 . . . . cancel factors of 3

q -1 = 6 -p . . . . . multiply by -(6 -p)

q + p = 7 . . . . . matches choice D

Find the equation of a line, in slope-intercept form of a line that passes through the point (-5, -1) and is parallel to -2x+4y=

Lana71 [14]

Answer:

$y=\frac{1}{2}x+\frac{3}{2}$

Step-by-step explanation:

Let's write $-2x+4y=8$ to slope-intercept form.

We do this by solving for $y$

$-2x+4y=8\\$

Add 2x to both sides

$4y=8+2x$

Divide both sides by 4

$y=\frac{1}{2} x+2$

Now that we have that equation in slope-intercept form, the question wants us to find a line that is parallel to it that passes the point (-5, -1).

A line is parallel to another line is they have the same exact slope.

The slope is $\frac{1}{2}$ .

Slope-intercept form: $y=mx+b$ , where $m$ is the slope and $b$ is the y-intercept.

So, let's see what we have here so far.

$y=\frac{1}{2}x +b$

All we have to do is find $b$ .

The question wants the line to pass the point (-5, -1).

Let's plug that point in.

$-1=\frac{1}{2} (-5)+b\\-1=\frac{-5}{2}+b\\\frac{3}{2} =b\\$

We have all the information needed to finish this problem!

So, the line that is parallel to $-2x+4y=8$ and passes through the point (-5, -1).

$y=\frac{1}{2}x+\frac{3}{2}$

Question : Which Point satisfies the system of equations y= 3x - 2 and y = -2x + 3

svetoff [14.1K]

Answer:

D

Step-by-step explanation:

y = 3x - 2 intercepts the y axis at -2

y = -2x + 3 intercepts the y axis at 3

the lines which satisfy these conditions intersect at point D

Michael has less than $20 to spend for a taxi. The charge for the taxi is

stiks02 [169]

Answer:

2m + 6 < 20

Step-by-step explanation:

A flat $6 plus $2 per mile is represented as 2m + 6, with m as the number of miles you can go.

This 2m + 6 must be LESS THAN Michael's $20. Therefore, this gives us:

<em><u>2m + 6 < 20</u></em>

2m: $2 per mile

6: the initial cost

20: how much money Michael has
