Answer:

Point form: (3,6)

Equation form: x=3, y=6

Step-by-step explanation:

Add the equations in order to solve for the first variable. Then plug this value into the other equations in order to solve for the remaining variables.

Alecsey [184]

Answer:

Frequency

Step-by-step explanation:

"A dot plot is a visual display in which each piece of data is represented by a dot above a number line, showing the frequency of each data value. The total number of dots in the plot is the total number of values in the data set. The data points must all be in the same units."

Write the standard form of the equation of the line that passes through (-2, -3) and (2,-5).
Naily [24]

Answer:

y= -1/2x-4

Step-by-step explanation:

By standard form, I'm assuming you mean slope-intercept form, which is y=mx+b. First, we need to find m, or the slope. To do this, we need to plug it into this equation: m= y2-y1/x2-x1. We can rewrite this with our two points, so we make it into m= -5+3/2+2. I did plus signs because if you subtract a negative number from a number, it has the same effect as addition does. Now, we have m= -2/4, which we can simplify to -1/2. Now, we have y=-1/2x+?. Now, let's plug in the numbers in slope-intercept form. I'll choose the ordered pair (-2, -3) for this example. Now that I've plugged the numbers in y=mx+b form (slope-intercept form), we have -3=(-1/2⋅-2)+b. Now, we solve it. First, we do the problem in the parenthesis, from that, we get 1. Now, we have -3=1+b, let's subtract 1 from both sides. Now, we have -4=b. That means our y-intercept is -4. Let's plug this back in the equation. We get y=-1/2x-4. I hope this helps!

Find the values. Question 1. Thanks!
kompoz [17]

Answer:

x=5 and y=8

Step-by-step explanation:

Find x:

3x - 2 = x + 8

-x          -x

2x - 2 = 8

     +2    +2

2x = 10

----   ----

2       2

x = 5

Find y:

6y - 7 = y + 33

-y         -y

5y - 7 = 33

     +7    +7

5y = 40

----   -----

5       5

y = 8

I need help finding the missing angle with work plz <br> ANSWER ASAP!!!!!!
Gemiola [76]

Answer:

The unknown angle is 80

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

Let the unknown angle be x

20+80+x = 180

Add like terms

100+x = 180

Subtract 100 from each side

100-100+x=180-100

x = 80
