The Second One ^What Is The Y-intercept For The QuadraticY=4x^2 + 5x - 7?

Answers

Answer 1

Answer: (0,-7)

HOPE I HELPED

Step-by-step explanation:

Answer 2

Answer:

-7

Step-by-step explanation:

Since you are trying to solve for y, you set all the x values to 0.

(Y intercept occurs when x = 0, thats why you sub 0 for all x)

y= -4(0)^2[tex]y=-4(0)^{2} +5(0) -7[/tex]

this simplifies to

y=-7

the massive rear tire of a tractor rotates and moves the tractor 100 yards across a field in 4 minutes. Determine the linear velocity of the outer edge of the massive tire. Is the linear velocity of the outer edge of the smaller tire faster or slower than the massive tire? Which has a greater angular velocity?

Answers

9514 1404 393

Answer:

  a) 25 yards per minute

  b) linear velocity is the same

  c) smaller tire has greater angular velocity

Step-by-step explanation:

a) The linear velocity of the edge of the tire is the same as the linear velocity of the tractor: (100 yd)/(4 min) = 25 yd/min

__

b) All parts of the tractor have the same linear velocity. The outer edge of the smaller tire is moving at the same linear velocity.

__

c) Because the smaller tire must make more turns to cover the same distance in the same time, its angular velocity (turns/time) is greater.

The smaller tire has greater angular velocity.

Solve for x

Answers

Answer:

x=2

Step-by-step explanation:

-2x+4=6x-12  Add 2x to both sides.

+2x    +2x

4=8x-12         Add 12 to both sides.

+12  +12

16=8x            Divide by 8 on both sides.

/8 /8

2=x

Hope this helps you out and have a great day (～^▽^)～

Answer:

x=2

Step-by-step explanation:

-2x + 4 = 6x - 12

First add 2x to each side: 4=6x−12+2x

Now simplify 6x-12+2x: 4=8x-12

add 12 to both sides: 4+12=8x

Simplify 4+12: 16=8x

Divide both sides by 8: 16/8

you end up with x=2

3x+4=9x-8= ????????????

Answers

3x+4=9x-8=2 the answer would be 2
Answer:

Simplifying
3x + 4 = 9x + -8

Reorder the terms:
4 + 3x = 9x + -8

Reorder the terms:
4 + 3x = -8 + 9x

Solving
4 + 3x = -8 + 9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9x' to each side of the equation.
4 + 3x + -9x = -8 + 9x + -9x

Combine like terms: 3x + -9x = -6x
4 + -6x = -8 + 9x + -9x

Combine like terms: 9x + -9x = 0
4 + -6x = -8 + 0
4 + -6x = -8

Add '-4' to each side of the equation.
4 + -4 + -6x = -8 + -4

Combine like terms: 4 + -4 = 0
0 + -6x = -8 + -4
-6x = -8 + -4

Combine like terms: -8 + -4 = -12
-6x = -12

Divide each side by '-6'.
x = 2

Simplifying
x = 2
