Answer:
Step-by-step explanation:
Just the slope, so we can simply apply the definition, as variation in y over the variation in x
Answer:
when you divide a negative number by a negative number the quotient is always positive.when you divide two negative number then the quotient is always positive
Step-by-step explanation:
:>
I believe it is -8 since the point where the line is x=80 and y=-10. Then you divide x/y (80/-10) and get -8.
Answer:
x+y < 28
Step-by-step explanation:
1. Look at your variables: x is the first number and y is the second.
2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.
3. Write out your inequality: x+y < 28
Answer:
Step-by-step explanation:
we know that
Triangles BDR and QDC are similar, because QC and BR are parallel lines
If two figures are similar, then the ratio of its corresponding sides is equal and is called the scale factor
In this problem
substitute the values
