Answer:
1. x = 15
2. x = - 9/7
3. x = 11/3
Step-by-step explanation:
<u>Part</u><u> </u><u>one</u><u>,</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>3</u><u>+</u><u>1</u><u>/</u><u>5</u><u>x</u>
to find x-intercept/zero, substitute y= 0
0 = 3 + 1/5
multiple both sides of the equation by five.
0 = 15 + x
move the variable to the left.
-x=15
change the signs on both of the equations.
x = -15
your solution is x = -15.
<u>Part</u><u> </u><u>two</u><u>,</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>-7x</u><u> </u><u>-9</u>
Move variable to the left hand side and change its sign.
7x = -9
Divide both sides of the equation by 7.
x=-9/7
Solution is x = - 9/7
<u>Part</u><u> </u><u>three</u><u>,</u><u> </u><u>y</u><u>=</u><u> </u><u>1</u><u>1</u><u> </u><u>-3x</u>
to find x intercept y and substitute for zero.
0= 11 - 3x
move variable to the left hand side and change its sign.
3x= 11
divide both sides by 3.
x= 11/3
Solution is x = 11/3
Answer: $728
Step-by-step explanation:
Look at pic!
Let x stand for the number.
x-3^2
Simplify.
x-9
This cannot be simplified any more.
