Question

Please help me with those question please help with out number 1

Answer 1

Answer:

1) For each value of x, a value of y is increased by 5.

x = 0, y = 5

x = 1, y = 10

x = 2, y = 15

x = 3, y = 20

------------------------------------------------------------------------------------------

2) For each two values of x, a value of y is increased by 10.

x = 0, y = -2

x = 2, y = 8

x = 4, y = 18

x = 6, y = 28

-------------------------------------------------------------------------------------------

3)

x = 0, y = 1

x = 1, y = $\frac{7}{5}$

x = 5, y = 3

x = 10, y = 5

-------------------------------------------------------------------------------------------------

4)

x = 0, y = 2

x = 1, y = 17

x = 2, y = 32

x = 5, y = 77

Step-by-step explanation:

This is as easy as replacing x for the actual value show on the table.

1)

$y=5x+5$

When x = 0, y = ?

$y=5(0)+5\\y=0+5\\y=5$

When x = 1, y = ?

$y=5(1)+5\\y=5+5\\y=10$

When x = 2, y = ?

$y=5(2)+5\\y=10+5\\y=15$

When x = 3, y = ?

$y=5(3)+5\\y=15+5\\y=20$

-------------------------------------------------------------------------------------------------------

2)

$y=5x-2$

When x = 0, y = ?

$y=5(0)-2\\y=0-2\\y=-2$

When x = 2, y = ?

$y=5(2)-2\\y=10-2\\y=8$

When x = 4, y = ?

$y=5(4)-2\\y=20-2\\y=18$

When x = 6, y = ?

$y=5(6)-2\\y=30-2\\y=28$

----------------------------------------------------------------------------------------------------

3)

$y=\frac{2}{5}x +1$

When x = 0, y = ?

$y=\frac{2}{5}(0) +1$

$y=0 +1\\y=1$

When x = 1, y = ?

$y=\frac{2}{5}(1) +1\\y=\frac{2}{5} +1$

$y=\frac{2}{5}+1(\frac{5}{5})\\ y=\frac{2}{5}+\frac{5}{5} \\y=\frac{7}{5}$

When x = 5, y = ?

$y=\frac{2}{5}(5) +1\\y=2+1\\y=3$

When x = 10, y = ?

$y=\frac{2}{5}(10) +1\\y=2(2) +1\\y=4+1\\y=5$

-------------------------------------------------------------------------------------------------

4)

$y=15x+2$

When x = 0, y = ?

$y=15(0)+2\\y=0+2\\y=2$

When x = 1, y = ?

$y=15(1)+2\\y=15+2\\y=17$

When x = 2, y = ?

$y=15(2)+2\\y=30+2\\y=32$

When x = 5, y = ?

$y=15(5)+2\\y=75+2\\y=77$

Answer 2

Answer:
• Table #1
2, 10, 15, 20

• Table #2
-2, 8, 18, 28

• Table #4
1, 7/5, 3, 5

• Table #5
2, 17, 32, 77

Explanation:
• Solving Table #1

y = 5(0) + 5
y = 5

y = 5(1) + 5
y = 5 + 5
y = 10

y = 5(2) + 5
y = 10 + 5
y = 15

y = 5(3) + 5
y = 15 + 5
y = 20

• Solving Table #2

y = 5(0) - 2
y = -2

y = 5(2) - 2
y = 10 - 2
y = 8

y = 5(4) - 2
y = 20 - 2
y = 18

y = 5(6) - 2
y = 30 - 2
y = 28

• Solving Table #4

y = 2/5(0) + 1
y = 1

y = 2/5(1) + 1
y = 2/5 + 1
y = 7/5 or 1 2/5

y = 2/5(5) + 1
y = 2 + 1
y = 3

y = 2/5(10) + 1
y = 4 + 1
y = 5

• Solving Table #5

y = 15(0) + 2
y = 2

y = 15(1) + 2
y = 15 + 2
y = 17

y = 15(2) + 2
y = 30 + 2
y = 32

y = 15(5) + 2
y = 75 + 2
y = 77
