Answer:
6.4 units
Step-by-step explanation:
c = √(x1 - x2)^2 + (y1 - y2)^2
c = √(3 - 7)^2 + (-3 + 8)^2
c = √(-4)^2 + (5)^2
c = √16 + 25
c = √41
c = 6.4031...
c = 6.4

Answer:
Yes, the are the right degrees.
Answer:
I do agree
Step-by-step explanation:
I know 10. is right because it is a right angle which id usually 90 degrees.
I'm pretty sure 11. is right because I know it is an obtuse angle and I think the number you gave is close if not it.
I know 12. is right because that angle looks the same as DBA which is already labeled 54 degrees.

Haddasah and Devon went shopping together. Haddasah bought 6 oranges and 5 lemons for $5.67. Devon bought 3 oranges and 7 lemons for $4.32. Their purchases can be modeled by a system of equations. A. Write a system of equations that represents this situation. Define the variables.
Answer: Define variables:
x = Cost of orange
y= Cost of lemon
System of equations that represents this situation:
6x+5y = 5.67
3x+7y = 4.32
Step-by-step explanation:
Let x = Cost of orange
y= Cost of lemon
Cost of both = (Number of oranges) x (Cost of orange) + (Number of lemons) x (Cost of lemon)
As per given,
6x+5y = 5.67
3x+7y = 4.32
Hence, system of equations that represents this situation:
6x+5y = 5.67
3x+7y = 4.32

The money collected from a Saturday car wash are directly proportional to the number of cars washed. The total money collected after 7 cars is $140. Write an direct variation equation relating the money collected (m) and the number of cars washed
Answer:
[tex]m=20c[/tex]
Step-by-step explanation:
Let m represent the total money collected and c represent the amount of cars washed.
We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:
[tex]m=kc[/tex]
Where k is a constant.
We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:
[tex]140=7k[/tex]
Find k. Divide both sides by 7:
[tex]k=20[/tex]
So, the value of k is 20.
We can now substitute k back into our direct variation equation:
[tex]m=20c[/tex]
This means that every car costs $20 to wash.
And we're done!
Answer:
7x140=980
Step-by-step explanation:

write the sentence as an inequality
a number m is more than -7 2/3 or at most -10
See attachment for math work and answer.
The given statement in the form of inequality can be written as,[tex]-7 \dfrac{2}{3} \leq m \leq -10[/tex]
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that,
A number m is more than -7(2/3) or at most -10
From the given data it is observed that the value of the number lies between -7(2/3) and -10.\
The given data can be written in the terms of inequality as,
[tex]-7 \dfrac{2}{3} \leq m \leq -10[/tex]
Thus, the given statement in the form of inequality can be written as,[tex]-7 \dfrac{2}{3} \leq m \leq -10[/tex]

What is the equation of the line that passes through the points (-6,-7) and (6,3)
Answer:
[tex]y=\frac{5}{6} x-2[/tex]
Step-by-step explanation:
Point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]where [tex](x_1, \ y_1)[/tex] are coordinates of a point that the line passes through, and [tex]m[/tex] is the slope of the line.
We are given two points that the line passes through, but we are not given the slope.
We can find the slope by using the slope formula:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]where [tex](x_1, \ x_2)[/tex] and [tex](y_1, \ y_2)[/tex] are two points that the line passes through.
Substitute (-6, -7) and (6, 3) into the slope formula:
[tex]\frac{3-(-7)}{6-(-6)} = \frac{10}{12} = \frac{5}{6}[/tex]The slope of this line is 5/6. Now we are able to use the point-slope equation to find the slope-intercept equation [tex](y=mx+b)[/tex] of this line.
Substitute a point that the line passes through and the slope of the line into the point-slope equation. I'm using the point (6, 3).
[tex]y-y_1=m(x-x_1)[/tex][tex]y-(3)=\frac{5}{6} (x-(6)[/tex][tex]y-3=\frac{5}{6} (x-6)[/tex]Distribute 5/6 inside the parentheses.
[tex]y-3=\frac{5}{6} x-\frac{30}{6}[/tex][tex]y-3=\frac{5}{6} x-5[/tex]Add 3 to both sides of the equation.
[tex]y=\frac{5}{6} x-2[/tex]This is the equation of the line that passes through (-6, -7) and (6, 3) in slope-intercept form.
