Step-by-step explanation:
26=r+10
subtract 10 from both sides
26-10=16. 10-10=0
16=r
Independent variables are things that can stand alone. Which set of these variables does not rely on each other? For example the income and savings. I want 1,000,000 in my savings account, however my income is not nearly that high since I only make 19,000. Look at the other pairs and see if there is a correlation between them.
Numbers are 4 and 8
<u>Step-by-step explanation:</u>
Step 1:
Let the numbers be x and y. Given that their sum is 12 and difference is 4. Form equations for this data.
⇒ x + y = 12 ------ (1)
⇒ x - y = 4 -------- (2)
Subtract eq (2) from (1)
⇒ 2x = 8
⇒ x = 4
Step 2:
Find y.
⇒ y = 12 - x = 12 - 4 = 8
Any function is also a relation. The function shown in the graph can be described by ...
C. both a relation and a function
Two lines perpendicular to each other having slopes m1 and m2 are related as:
m1 * m2=-1 ...................... (1)
First we find slope m1 of the line y=7/5x-3/5
comparing this equation with slope intercept form y=mx+b,
slope m1=7/5
NOw using rule (1) here to get value of m2
7/5 * m2 =-1
m2 =-5/7...................(2)
Now the line passes through (-4,3) and has slope m2 =-5/7
we use slope intercept form to get the value of y intercept
y=mx+b
3=(-5/7)(-4) +b
3=2.86 +b
b=0.14
At last we plug the value of b and m in slope intercept form to get the final equation as :
y=(-5/7) x + 0.14
