A) Complete the table of values for y = x2 + x - 4

Mathematics

Yuri [45]3 years ago

Answer:

The values of y for each value of x are:

x = -3, y =2

x = -2\: , y =-2

x = -1\: , y =-4.

x = 0\: , y =-4

x = 1\: , y = -2.

x = 2\: , y =2

x = 3\: , y = 8

Step-by-step explanation:

We have all the values of x, they are from -3 to 3 passing for 0.

Now, we know that y is a quadratic function (y=x²+x+4)

Therefore, we just need to put each value of x into the quadratic equation to find each y value.

When:

x = -3, y = (-3)^2+(-3)-4=2

x = -3\: , y = 2

We can do this for all values of x, so we will have:

x = -2\: , y = (-2)^2+(-2)-4=-2

x = -1\: , y = (-1)^2+(-1)-4=-4.

x = 0\: , y = (0)^2+(0)-4=-4

x = 1\: , y = (1)^2+(1)-4=-2.

x = 2\: , y = (2)^2+(2)-4=2

x = 3\: , y = (3)^2+(3)-4=8

I hope it helps you!

The product of three whole numbers is 120 how many different possibilities are there for the three whole numbers
Sphinxa [80]
We can factor 120 into
2 * 2 * 2 * 3 * 5

I think there are nine different possibilities
1) 8 * 3 * 5
2) 4 * 2 * 15
3) 4 * 6 * 5
4) 4 * 10 * 3
5) 2 * 2 * 30
6) 2 * 3 * 20
7) 2 * 5 * 12
8) 2 * 6 * 10
9) 2 * 15 * 4

Four times a number added to 7 times the number equals 44.
zysi [14]
If you're looking for the value of the number, then here's how:
Let's call the number x
4x + 7x = 44
11x = 44
÷ 11
x = 4
So the number you're looking for is 4, if you wanted to know something else then let me know!

Can someone please help me with math.
Inessa05 [86]

4- 20

I created an equation for this one:

4x+x=100

  • 4x= four times the amount of the other number
  • x= the number
  • combine like terms

5x=100

  • divide by 5

x=20

5. One pretzel costs $3

Create an equation:

  • 2s+p=7
  • 4s+3p=17

Mulitply 2s+p=7 by -2 so you can use elimination.

  • -4s-2p=-14
  • 4s+3p=17

Combine equations

p=3
