X can be any number in the graph as long as it is on the x-axis therefore you can put x as -1,0 and 1. Then you would need to replace the ‘x’ in the equation so it would look like y=-2*1+3. You replace ‘x’ with every number you put in the x boxes. Then just solve the equations
y=-2*1+3
Y=-2*0+3
Y=-2*-1+3
They would give you the y axis coordinates so then you just put them together for the middle column.
Answer
y=-2*1+3=1
Y=-2*0+3=3
Y=-2*-1+3=5
Coordinates are (1,3) (0,3) (-1,5)
Answer:
220
Step-by-step explanation:
The surface area is given by
SA = 2 ( lw+wh+lh) where l is length h is height and w is width
SA = 2(3*4 + 3*14+ 4*14)
= 2(12+42+56)
= 2(110)
= 220
Answer:
{16, +infinity}
Step-by-step explanation:
Represent the number with n

Find the solution set
From the question, we have that;
4½n - 9½ > 62.5
Convert all numbers to decimal
4.5n - 9.5 > 62.5
Add 9.5 to both sides
4.5n - 9.5 + 9.5 > 62.5 + 9.5
4.5n > 72
Multiply both sides by 2
2(4.5n) > 72 * 2
9n > 144
Multiply both sides by ⅑
⅑ * 9n > 144 * ⅑
n > 16
This implies that n ranges to infinity from positive 16;
Hence, the correct answer is {16, +infinity}
