Answer:

All integers greater than 4 (5 or greater) and less than -4 (-5 or less)

Step-by-step explanation:

x² + bx + 5

b² - 4ac 》 0

b² - 4(1)(5) 》 0

b² - 20 》 0

b 》 sqrt(20)

b 》 4.47

b 《 -sqrt(20)

b 《 - 4.47

All integers greater than 4 (5 or greater) and less than -4 (-5 or less)

Write a real world problem that involves classifying a quadrilateral then solve the problem.

Anastasy [175]

An amusement park ride has a moving platform attached to four swinging arms. The platform swings back and forth, higher and higher, until it goes over the top and around in a circular motion. In the diagram below, AD and BC represent two of the swinging arms, and DC is parallel to the ground
(line l). Explain why the moving platform AB is always parallel to the ground.

Given :-

The slope of the line through points (3,y) and (4,10) is 7 .

To Find :-

The value of y .

Solution :-

As we know that the slope of the line is difference of ordinate divided by the difference of absicca as ,

$\longrightarrow$ m = y -10 / 3 - 4

$\longrightarrow$ 7 (-1) = y -10

$\longrightarrow$ -7 = y -10

$\longrightarrow$ y = 10 -7

$\longrightarrow$ y = 3

Hence the required answer is 3.

PLEASE HELP ME IM MARKING ANSWER BRAINLIEST RIGHT NOW!!Mr. Youngbear buys T-shirts in boxes

Musya8 [376]

Step-by-step explanation:

1. Ok so first we need to figure out how many boxes of shirts he bought. In each box there are 20 shirts and he sold 93. So if we round it, he bought about 100 T-shirts. 100 ÷ 20 = 5. So he bought 5 boxes of shirts.

2. Next we need to figure out how much he spent on the shirts. 5*80=400. So he spent $400 dollars on the shirts.

3. We need to find out the amount of money he made from selling the shirts. 6*93=558

4. We need to find the profit so you subtract the total expenses from the total revenue. 558-400= 158. So the profit is $158

Answer: Mr. Youngbear made 158 dollars worth of profit after selling 93 T-shirts.

(I dont know if this is correct, but I hope I was able to help!)
