7x - 3 > 18
Add 3 to both sides
7x > 21
Divide both sides by 7:
X > 3
Since x has to be greater than 3 the smallest whole number that would work is 4
Answer: 4
Answer:
see below
Step-by-step explanation:
7x – 3 > 18
Add 3 to each side
7x – 3+3 > 18+3
7x> 21
Divide by 7
7x/7 >21/7
x > 3
The smallest integer value of x is 4
What are the roots of the function f(x) = x2 + 2x – 1? a. x = ± √ _ 2 b. x = − 1 ± √ _ 2 c. x = 2 ± √ _ 2 d. x = 1 ± √ _ 2
Step-by-step explanation:
Root of the function, where y = 0
f(x) = x² + 2x - 1
0 = x² + 2x - 1
x² + 2x - 1 = 0
x² + 2x = 1
x² + 2x + 1 = 1 + 1
(x + 1)² = 2
x + 1 = ±√2
x = -1 ± √2
Roots → x = -1 ± √2

Step-by-step explanation:
A linear function has the same y-intercept as x + 4y = 20 and its graph contains the
point (7, 7). Find the y-intercept of the linear function.
y-intercept: (0,___)
Answer:
(0,5)
Step-by-step explanation:
x + 4y = 20
4y = -x + 20
y = -1/4x + 5
The y - intercept of the line is 5

at the mud factory, people's job is to scoop up mud and make it into kilogram blocks of mud. She loves her job today there were 2,913 milligams of mud trucked in. Each mud block is precisely 1 kilogram, no less no more. How many mud blocks can she make today
Answer: 0 bricks
Step-by-step explanation:
2,913 milligrams (mg) is only 2.913 grams. It takes 1,000 grams to make a kilogram. 2,913 mg is only 0.002913 kg.
The teachers had to transport 165 students by bus on a field trip. Each bus holds 64 students. How many buses do they need to order?
Answer:
B
Step-by-step explanation:
Divide the number of students by the capacity of each bus
. 165 / 64 = 2 (busses) + 37/64 (remainder)
165 students
each bus= 64 students
to find:how many buses they need to order in order to take 165 students.
solution:[tex] \frac{165}{64} [/tex]
[tex] = 2.578125[/tex]
[tex] = 2 \frac{37}{64} [/tex]
hence, the correct answer is option B.

Answer:
x = 13
angle A = 97degrees
Step-by-step explanation:
TO GET "x=13"
since the angle is an alternate angle , it adds up to 180deg so :-
A+B =180
6x + 5 + 4x + 45 = 180
then u add the like terms :-
10x + 50 = 180
then u substitute:-
10x = 180-50
10x = 130
10x÷10 = 130 ÷10 ( this is to cancel the 10 )
x = 13
___________________________________________________________________
TO GET "A=97"
since we need the magnitude of A, we need to .... um I dunno how to explain this soo.....
the equation for A = 6x + 5
180 is the sum of the 2 angles so :-
180 - 5 - (13 × 6) 13×6 is because x=13
180 - 5 - 78= 97
I subtracted these since we need to cancel to get to an answer
I hope u get it.... sorry if u can't understand
and sorry once again if this answer.... I did it in a rush

Can you please help me I need to pass for my basketball game Tuesday please help if I don’t pass i can’t play !!
Answer:
x = 17
Step-by-step explanation:
The two given angles are supplementary angles, but also all angles on a straight light must add up to 180°:
3x + 14 + 7x - 4 = 180
Add like terms
3x + 7x + 14 - 4 = 180
10x + 10 = 180
Subtract 10 from both sides to isolate 10x:
10x + 10 - 10 = 180 - 10
10x = 170
Divide both sides by 10:
10x ÷ 10 = 170 ÷ 10
x = 17
Hope this helps!

Help Please. It's 10:11 AM right now. This due by 12 PM or in 2 more hours. I don't know this.
Answer:
B) 2,000.
Step-by-step explanation:
As the mean is 6000 the total number of students = 5*6000
= 30,000.
If graduates are excluded we have 4*7000 = 28,000 students.
So the number at graduate level
= 30,000 - 28,000
= 2,000.

Examine the statement.
Rules for naming compounds are beneficial to the scientific community.
Do you agree or disagree with the statement? Be sure to explain the reasons for your viewpoint when you answer.
Furthering the Discussion
If you need more material to continue the conversation, use these questions as a guide.
What types of real-life situations or scenarios do you think benefit from having rules?
What types of real-life situations do you think are hindered by having rules?
Answer/Explanation:
I agree with the statement because primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance. The first separation of importance is to distinguish between inorganic and organic compounds.

Answer:
<AMC=75°Step-by-step explanation:
if <C=90 and <B = 30, then <A=60 (because <A+<B+<C=180, as ABC is a triangle)
if CM is a angle bisector then it divides <C in half, so <ACM=<MCB=45
since <ACM=45;
<A = 60;
then <AMC = 180-(45+60),
<AMC = 180-105,
<AMC = 75.

Solve one third plus seven ninths equals blank
Question 1 options:
ten twenty sevenths
eight ninths
ten ninths
nine thirds
Answer:
the answer is 10/9.
Step-by-step explanation:
Please give BRANIEST and 5 stars if correct!
Answer:
ten ninths
Step-by-step explanation:
"one third plus seven ninths" can be rewritten symbolically as
1/3 + 7/9 and we note that the LCD is 9. Thus,
1/3 + 7/9 = 3/9 + 7/9 = 10/9 (or "ten ninths")
Liquid A has a density of 1.42 g/cm². 7 cm of
liquid A is mixed with 125 cm of liquid B to make
liquid C. Liquid C has a density of 1.05 g/cm. Find
the density of liquid B.
Give your answer correct to 2 decimal places
Answer:
A=density=1.42g/cm^3
mass=9.94g
volume=7cm^3
B=density =?
mass=128.66g
volume=125cm^3
C=density=108g/cm^3
mass=138.6g
volume=132cm^3
massA 1.42×7=9.94g
massB 138.6-9.94=128.66g
massC 132×1.05=138.6g
Density of B =mass/ volume
=126.66÷ 125
= 1.03g/cm^3

The equation Y-5 = 6(x+1) is written in point-slope form. What is the equation written in slope-intercept form?
O y = 6x + 11
O y = 6x - 1
O y = 6x - 4
O y = 6x + 6.
Answer:
Option A: y = 6x + 11
Step-by-step explanation:
Given the linear equation in point-slope form, y - 5 = 6(x + 1), and that we must determine its equivalent slope-intercept form, y = mx + b:
First, we must distribute 6 into the parenthesis on the right-hand side of the equation:
y - 5 = 6(x + 1)
y - 5 = 6x + 6
Lastly, we must add 5 to both sides of the equation to isolate y:
y - 5 + 5 = 6x + 6 + 5
y = 6x + 11
Therefore, the slope-intercept form is: y = 6x + 11, which matches Option A.

Apply the distributive property to create an equivalent expression.
(3−8y)⋅(−2.5)=
Answer:
-7.5+20y
Step-by-step explanation:
To apply the distributive property, you have to distribute the multiplication of -2.5 to both 3 and -8y.
First, multiply 3 and -2.5 to get -7.5
Then, multiply -8y and -2.5 to get 20y.
Finally, add these values together

What is the zero of the function represented by this graph?
Answer:
Step-by-step explanation:
The easiest way to answer your question is to graph it. I've enclosed a graph for you. The answer to the question as it is asked is y ≥ 2.
The answer to your question (which is a much more interesting question) is that there is no 0. A zero of a function must touch or intersect the x axis.
