3 and 4
Step-by-step explanation:
y=5x
y=5(0)
y=0
y=5x
y=5(10)
y=50
y=5x
y=5(51)
y=255
y=5x
y=5(400)
y=2000
Answer:
6 years
Step-by-step explanation:
So each person's age can be represented as a linear equation, since each year our age increases by 1. It can be represented in the slope-intercept form: y=mx+b. The slope in this case is going to be 1, since the time is going to be years, and each year everyone's age goes up by 1 (of course if you're still alive...) and y-intercept in this case represents their current age.
So the father can be represented as: y=x+38
The sons can be represented as: y = x+13 and y=x+5
The daughter can be represented as: y=x+8
So adding up all his children you get:
(x+13)+(x+5)+(x+8)
This gives you the equation:
3x+26
Now set this equal to the father's age to solve for x (in this context it's years)
3x+26=x+38
Subtract from both sides
2x+26=38
Subtract 26 from both sides
2x=12
Divide both sides by 2
x=6
So in 6 years the father will be the same age as his children put together

“Divide 40 by 9” means 40÷9
Axel did 9÷40
9 goes outside the dog house (⬜️)
9 can’t go into 4 so move to the next number
9 goes into 40 4 times.
9 times 4 equals 36
40 minus 36 equals 4
There are no other numbers under the house can’t go into four and 9 can’t go into 4. That means there is a remained of four.
4s + 12 or 4(s + 3) would be equivalent to the expression!
7. C. y = 2x - 3
8. Both are correct
Step-by-step explanation:
7. Multiply the x value by 2, then subtract three. You eill notice they all equal to the corresponding y value
8. Divide each value by 2, (the same as multiplying by one half ) then subtract 2 from the quotient. you will get the corresponding y value for both tables.
