Find the inequality represented by the graph.
Answer:
y > 4x - 2
Step-by-step explanation:
y-intercept is at -2
slope is rise by 4, run by 1
if you don't know where to shade, select a point and plug it in to see if T or F
example (0, 0)
is 0 > 4(0) - 2
is 0 > -2 True, so shade to the left because this is where (0,0) is
Answer:
Step-by-step explanation:
Analyze what each part of the inequality means mathematically.x is the solution of the problem, the quantity you are looking for.6x means that, for a reason given in the problem, the quantity you are looking for is multiplied by 6.− 18 means that, for a reason given in the problem, 18 is subtracted from 6x.≤ 18 means that after multiplying the solution x by 6 and subtracting 18 from it, the result is at most 18.Think of some different situations in which a quantity x might be multiplied by 6.You plant 6 seeds from x different seed packets, and you want to know from how many different seed packets you plants seeds.Build on the situation and adjust it to create a verbal description that takes all of the information of the inequality into account.Elrich planted 6 seeds from each of x different seed packets in his garden. To plant these seeds, he had to remove 18 plants that were already in the garden. Including the plants he removed and the seeds he planted, he expected to have at most 18 plants in the garden. From how many different seed packets did Elrich recently plant seeds?

NOTE: Angles not necessarily drawn to size . what is x?
Answer: 45
Step-by-step explanation: 160-115= 45 you do this because the angles are across the vertex from each other.
Answer:
X=45
Step-by-step explanation:
Method 1 ( the long one)
So AED and CEB are vertical angles, that means that the are the same and have the same value.
So 115 plus x equal 160.
115 + x = 160
from there we just have to subtract 115 from both sides to get x by itself.
115 + x = 160
-115 -115
_________________
x=45
Method 2 (short one
If you know that those are vertical angles, then just subtract 115 from 160 and there you go. You get 45.
Write an equation to represent the measures of the angle

Answer:
1. 2/3 ,-5/4 , -1.8 , 3.2
2. -2 and 0
3. 4 and 16
Step-by-step explanation:
1.Rational numbers should have a numerator and a denominator. An integer should not be a decimal or a fraction.
In this case : 2/3 ,-5/4 , -1.8 , 3.2
2. Whole numbers are counting numbers. An integer can be non-negative, positive, negative or zero.
In this case : -2 , 0
3. Whole numbers remaining are ;

What is the value of E(-1) n (3n+2)?
====================================================
Explanation:
The weird looking E symbol is the greek uppercase letter sigma. It refers to a sum.
It tells us to add up terms in the form (-1)^n*(3n+2) where n is an integer ranging from n = 1 to n = 4.
------------------
If n = 1, then we have
(-1)^n*(3n+2) = (-1)^1*(3*1+2) = -5
Let A = -5 as we'll use it later.
------------------
If n = 2, then
(-1)^n*(3n+2) = (-1)^2*(3*2+2) = 8
Let B = 8 since we'll use this later as well
------------------
If n = 3, then
(-1)^n*(3n+2) = (-1)^3*(3*3+2) = -11
Let C = -11
-------------------
If n = 4, then
(-1)^n*(3n+2) = (-1)^4*(3*4+2) = 14
Let D = 14.
--------------------
We'll add up the values of A,B,C,D to get the final answer
A+B+C+D = -5+8+(-11)+14 = 6
This means that
[tex]\displaystyle \sum_{n=1}^{4}(-1)^n(3n+2) = 6[/tex]

Andrew borrowed $700 from the bank to start a pressure washing business. The bank charged a simple interest rate of 7% per year. If it takes Andrew 3 years to pay back the loan, how much interest will he pay?
Answer:
$147Step-by-step explanation:
Given:
Loan amount = $700Interest rate = 7% simpleTime = 3 yearsInterest amount:
$700*3*0.07 = $147Answer:
Simple interest=(Principal×Rate×Time)/100
Principal=$700, Rate=7%, & Time=3 years
→S.I. = (700×7×3)/100 = 147
Andrew has to pay a interest of $147.

find the exact value of tan30⁰ × cos30⁰
give your answer in its simplest form
ANSWER:
tan(30⁰)=√3/3
cos(30⁰)=√3/2
switch sides:sin(x) /√3/2 =√3/3
multiply both sides by 3:3·sin(x) /√3/2 =3·√3/3
simplify:2√3 sin (x) =√3
divide both sides by 2√3:2√3 sin (x) / 2√3 = √3 / 2√3
simplify:sin (x)= 1/2

Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. What does the ratio 5 : 13 represent in this situation? Use a model to show your work. Explain your reasoning.
Answer:
m
Step-by-step explanation:
The ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias in Myra's flower bed.
A ratio shows us the number of times a number contains another number.
Given that Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. Therefore, the ratio of number of Lilies to the number of tulips and zinnias are,
Ratio = Number of Lilies : Number of tulips and zinnias
Ratio = 5 : (7+6)
Ratio = 5 : 13
Hence, the ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias.

solving 2 step inequalities give three solutions for each inequality -3(1-z)<9
Answer:
-3, -2 and -1
Step-by-step explanation:
Given the inequality -3(1-z)<9
Expand
-3(1)-3z <9
-3-3z <9
Add 3 to both sides
-3-3z+3<9+3
-3z<12
Divide both sides by -3
-3z/-3 >12/-3
z > -4
The required solutions are values greater than -4 and they are -3, -2 and -1
