Answer: 2</h3>
==========================================================
Explanation:
x = number of years
y = height in feet
The equation for the first tree is
y = x+3
The slope is 1 to represent a rate of 1 ft per year of growth. The y intercept of 3 is the starting height. Refer to y = mx+b form.
For the second tree, the equation is:
y = 0.5x+4
This time we have a slope of 0.5 and a y intercept of 4.
Apply substitution to solve for x
y = x+3
0.5x+4 = x+3
0.5x-x = 3-4
-0.5x = -1
x = -1/(-0.5)
x = 2
The trees will be the same height in <u> 2 </u> years.
What will that height be? Plug x = 2 into either equation to find y. We should get the same y value.
y = x+3
y = 2+3
y = 5
Or we could say
y = 0.5x+4
y = 0.5*2+4
y = 1+4
y = 5
We've shown that both equations lead to y = 5 when x = 2. This means that at the 2 year mark, both trees are 5 feet tall. This helps confirm we have the correct x value.
Answer:
true
Step-by-step explanation:
given
= 
( cross- multiply )
4x = 40 ( divide both sides by 4)
x = 10
Answer:
-1/3
Step-by-step explanation:
Step 1. Simplify setup.
12/x - 6 = 18/x - 4
Step 2.Subtract 12/x from both sides.
-6 = 6/x - 4
Step 3. Add 4 to both sides.
-2 = 6/x
Step 4. Divide it all by 6 to leave X alone.
-1/3 = x
So X equals to -1/3.
Answer:
What ever the f(x) numbers are you just move -5 which is the x to the left. You move the +2 up from the y axis.
Step-by-step explanation:
Lets say I have (7,3) in the graph.
You count -5 from 7 which will be 2.
Then you count +2 from 3 which will be 5
The new dot or equation will be (2,5)
Hey there! :)
A pentagon is 5 sides, and if all sides are 7 inches, then the perimeter is 5 times 7 = 35.
