Mathematics
1 answer:
valentinak56 [21]3 years ago
4 0

Answer:

Step-by-step explanation:

1. y= 1-x² is quadratic because has the variable x to the second power

y = -x² +1 has quadratic term -x², and constant term is 1

2. y= 3x-5 +4x²

a. quadratic term is 4x² because has the variable x to the second power

b. linear term is 3x because has the variable x to the power of one

c. constant term is -5 because the variable x to the power 0 so there is no x

I am really bad at Math, does anyone know how many solutions are in these 1. 2x - x + 7 = x +3 + 4 2. -2(x + 1) = -2x + 5 3. 4x
timama [110]

Step-by-step explanation:

1. 2x - x + 7 = x +3 + 4

Collecting like terms;

2x - x - x = 3 + 4 - 7

2x = 0

x = 0

2. -2(x + 1) = -2x + 5

Expanding the bracket;

- 2x - 2= - 2x + 5

Collecting like terms;

- 2x + 2x = 5  + 2

0 = 7

It has no solution

3. 4x + 2x + 2 = 3x - 7

Collecting like terms;

4x + 2x + 3x = - 7 -2

9x = -9

x = -1

4. 4(2x + 1) = 5x + 3x + 9

Expanding the bracket

8x + 4 = 5x + 3x + 9

Collecting like terms

8x - 5x - 3x = 9 - 4

0 = 5

It has no solution

5. X + 2x + 7 = 3x - 7

Collecting like terms

x + 2x - 3x = - 7 - 7

0 = - 14

It has no solution

36 is 75 percent of what
Marta_Voda [28]
36 = 75% of what?

36 = 75% of x

36 = 0.75x

0.75x = 36

x = 36/0.75

x = 48

Therefore 36 is 75 percent of 48

Hope this explains it.

X + 3(10x divided by 5)
Cerrena [4.2K]
Let's simplify first
10x divided by 5 = 2x
Add 2x on 3 an you'll have 6x
And now you just combine like terms
which is x + 6x = 7x
So there's your answer 7x
