3x + 3 = 0 //Subtract -3 on both sides

3x = -3 //Divide 3 on both sides

x = -1

Here x = -1 and y is all the values where x = -1, so basically from negative infinity to infinity.

Make sure when writing the solution, y is any value and x stays the same.

Solution: (-1,0) and (-1,1)

//Hope this helps

A. Solve for y.<br> B. What is the measure of the missing angles?

Alik [6]

Answer: A.) y = 15 B.) (5y + 3)° = 78° (4y + 8)° = 68° and 34°

Steps:
180° - 146° = 34°

180 = 34 + (5y + 3) + (4y + 8)
180 - 34 = (5y + 3) + (4y + 8)
146 = (5y + 3) + (4y + 8)
146 = 5y + 3 + 4y + 8
146 = 9y + 11
146 - 11 = 9y
135 = 9y
135/ 9 = y
15 = y

(5y + 3)
5(15) + 3
75 + 3
78
(5y + 3) = 78

(4y + 8)
4(15) + 8
60 + 8
68
68 = (4y + 8)

Check:
68 + 78 + 34 = 180
180 = 180 ✅

You have the numbers 1-24 written on slips of paper. If you choose one slip at random, what is the probability that you will not

ra1l [238]

The probability of selecting a number not divisible by 3 is: 2/3

Step-by-step explanation:

There are two methods to solve the question.

We can find the probability of numbers not divisible by 3
We can find the probability of numbers divisible by 3 and then find the complement of it

We will use the second method:

Given:

There are 24 slips

S = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24}

n(S) = 24

Let A be the event that the slip number is divisible by 3

Then

A = {3,6,9,12,15,18,21,24}

n(A) = 8

The probability of number divisible by 3 is:

$P(A) = \frac{n(A)}{n(S)}\\=\frac{8}{24}\\=\frac{1}{3}$

The sum of the probability of an event's occurrence and non-occurrence is 1. So the probability of numbers divisible by 3 will be subtracted from 1 to find the probability of selecting a number not divisible by 3.

The probability of selecting a number not divisible by 3 will be:

$=1-\frac{1}{3}\\=\frac{3-1}{3}\\=\frac{2}{3}$

The probability of selecting a number not divisible by 3 is: 2/3

Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so very much!

Romashka [77]

Answer:

66.3 sq ft

Step-by-step explanation:

Here's the plan: we'll find the area of the circle then subtract the area of the triangle.

Area of circle:

A = pi•r^2

= pi•6^2

= 3.14•36

~= 113.04

Area of triangle:

A = 1/2bh

= 1/2(10.39)(9)

The height is the 6+3 in the image.

~= 46.755

Subtract to find

Area of Shaded:

113.04 - 46.755

= 66.285

Round to nearest tenth.

~= 66.3 sq ft
