You have an equation and a table with the x value given.

Replace x in the formula with the x value in the table and solve for y.

y = x^2 + 1

y = (-3)^2 + 1 = 9+1 = 10

y = (-2)^2 +1 = 4+1 = 5

y = (-1)^2 +1 = 1+1 = 2

y = (0)^2 + 1 = 0+1 = 1

y = (1)^2 +1 = 1+1 = 2

y = (2)^2 +1 = 4+1 = 5

y = (3)^2 +1 = 9+1 = 10

Working at their respective constant rates, machine a makes 100 copies in 12 minutes and machine b makes 150 copies in 10 minute
Marina86 [1]

Since both machines maintain their rate, the number of copies made and the elapsed time are proportional. This means that we can write a proportion like

\text{time}_1 : \text{copies in time}_1 = \text{time}_2 : \text{copies in time}_2

We know the performance of machine a for 12 minutes, and we want those for 30 minutes: the proportion becomes

12 : 100 = 30 : x \iff x = \dfrac{100\cdot 30}{12} = \dfrac{3000}{12} = 250

Similarly, we have for machine b

10 : 150 = 30 : x \iff x = \dfrac{150\cdot 30}{10} = \dfrac{4500}{10} = 450

So, together, the two machines make

250+450 = 700

copies.

Suppose you got 8 mangoes and 3 apples for $18 and 3 mangoes and 5 apples for $14.50.
Mandarinka [93]
Let x = cost of mango
y = c of apples 
<span>8x+3y=18.
3x+5y=14.5 </span>

<span> </span>
<span>24x+9y=54
24x+40y=116
multiplying them with 3 and 8 resectively. </span>
<span>subtract one from the other we get </span>
<span>40y-9y=116-54 </span>
<span>31y=62 </span>
<span>y=2.
cost of apple=2$  per apple
</span><span>8x+3y=18,
 8x+3(2)=18.
8x=12. x=12/8=1.5 </span>
<span>cost of mango i= 1.5 $ per mango
hope this helps</span>
