Solve this step by step using the quadratic function <br> y=x^2 +x+2
Ne4ueva [31]

Answer:

x=<u>+</u>\frac{\sqrt{4y-7}-1 }{2}

Step-by-step explanation:

Quadratic function =( -b<u>+</u>\sqrt{b^2+4ac}  )/2a

x^2+x+2-y=0

x=-1<u>+</u>\sqrt{1^2-4(2-y)} /2

x=-1<u>+</u>\sqrt{4y-7} /2

x=<u>+</u> \frac{\sqrt{4y-7}-1 }{2}

Pretty sure this is right. Would appreciate a brainliest

System of equations<br><br>y=1/2x +5<br>y=3x -5​
Art [367]

Answer: 4

Step-by-step explanation:

Set them equal to each other since they're both equal to y

3x-5=.5x +5

add 5 to both sides

3x=.5x+10

subtract .5x from both sides

2.5x=10

divide both sides by 2.5

x= 4

The table shows how an elevator 500 feet above the ground is descending at a steady rate.
lapo4ka [179]

Answer:

h(t) = -5t + 500

Step-by-step explanation:

At time zero, the elevator is at 500 ft.

At time 5 seconds, the elevator is at 475 ft.

The difference in height is -25 ft.

The elevator traveled -25 ft (25 ft down) in 5 seconds, so it travels at a speed of 5 ft per second. Since it is traveling down, its speed is -5 ft/sec.

For each second of travel, it loses 5 ft of height.

h(t) = -5t + 500
