Answer: y=-1x+5

Step-by-step explanation:

1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.

m = ∆y / ∆x

m = -1 / 1

m = -1

y= -1x + b

2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)

y = mx + b

4 = -1(1) + b

4 = -1 + b

5 = b

3. Plug in the values found into the formula.

y = -1x + 5

PLEASE PLEASE HELP ME OUT ITS URGENT <br><br><br> What are the solutions to the quadratic equation?

mixer [17]

Answer: Choice C) $x = 4\pm2\sqrt{10}$

This is the same as saying $x = 4+2\sqrt{10} \ \ \text{ or } \ \ x = 4-2\sqrt{10}$

=============================================================

Explanation:

First get everything to one side

x^2 + 13 = 8x + 37

x^2 + 13 - 8x - 37 = 0

x^2 - 8x - 24 = 0

Here we have a quadratic in the form ax^2+bx+c = 0

Note how a = 1, b = -8, c = -24

Those values are plugged into the quadratic formula below

$x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-8)\pm\sqrt{(-8)^2-4(1)(-24)}}{2(1)}\\\\x = \frac{8\pm\sqrt{160}}{2}\\\\x = \frac{8\pm\sqrt{16*10}}{2}\\\\x = \frac{8\pm\sqrt{16}*\sqrt{10}}{2}\\\\x = \frac{8\pm4*\sqrt{10}}{2}\\\\x = \frac{2(4\pm2\sqrt{10})}{2}\\\\x = 4\pm2\sqrt{10}$

This shows the answer is choice C.

The plus minus breaks down that equation these two solutions

$x = 4+2\sqrt{10} \ \ \text{ or } \ \ x = 4-2\sqrt{10}$

Juliette [100K]

Answer:

Probability that his students will get at least 3 is 0.9875

Step-by-step explanation:

In the given scenario the number of favorable outcomes are 3 out of 5 that is 3,4,5 out of five.

Probability = no of favorable outcomes/ sample space

Probability his students will get 3 or more = 3/5/48= 0.6/48= 0.0125

Probability of at least getting 3 or more = 1- Probability of getting 3 or more

Probability that his students will getting at least 3 = 1- P( 3 or more)

= 1- 0.0125

= 0.9875
