Answer:
15
Step-by-step explanation:
since 3d is multiplying, it would be set up as 3*5=15
Answer:
x=9
Step-by-step explanation:
Add similar elements: -5x+3x=-2x
-2x+15=-3
Subtract 15 from both sides
-2x + 15-15=-3-15
Simplify
-2x=-18
Divide both sides by -2
-21/-2 = -18/-2
Simplify
x=9
Answer: They are equivalent, and x = -4/7
Step-by-step explanation:
Fist we need to see what the answers to each of these equations are
7 + 5x = 3 - 2x
Subtract 7 on each side
5x = -4 - 2x
Add 2x
7x = -4
X = -4/7
Now the second one
7 + 7x = 3
Subtract 7
7x = -4
X = - 4/7
They are equal and x = -4/7
Answer:
y= 0.6x + 6 or y= 3/5x + 6
Step-by-step explanation:
The function for a linear function is y=mx+b.
We know that b is 6 because that is the y-intercept.
However to find m we need to see how much the x coordinates skip on the table and the y coordinates. We can see that x coordinates skip by 5s and the y corrdinates skip by 3. We than divide 3/5 to get o.6 and we get the equation. This video, tittled "Writing A Linear Equation From A Function Table" explains it much better than I can.
