Choose the graph of y = -3x – 1
Answer:
The line on the graph below is my answer.
The graph of function y = -3x – 1 has been drawn below.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given the line equation y = -3x – 1
At x = 0 ⇒
y = -3(0) - 1
y = -1
So,
A(0,-1) is the first point on the line.
At y = 0 ⇒
0 = -3x – 1
x = -1/3
So,
B(-1/3,0) is the second point on the line.
Hence "The graph of function y = -3x – 1 has been drawn below".

what is 9/32 + 7/8 plz help
Answer:
1 5/32
Step-by-step explanation:
First, find common denominators. What you do to the denominator, you must do to the numerator.
First, multiply 4 to both the numerator and denominator of the second fraction:
(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32
Next, add across:
9/32 + 28/32 = 37/32
Simplify. Turn the improper fraction into a mixed fraction:
37/32 = (32 + 5)/32 = 1 5/32
1 5/32 is your answer.
~
Answer:
37 /32
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 8 and 32 is 32
For the 1st fraction, since 8 × 4 = 32,
7 /8 = 7 × 4
8 × 4 = 28 /32
Likewise, for the 2nd fraction, since 32 × 1 = 32,
9 /32 = 9 × 1
32 × 1 = 9 /32
Add the two fractions:
28 /32 + 9/32 = 28 + 9 /32 = 37 /32
So, 7/8 + 9/32 = 37/32
In mixed form: 1 5 /32

Is 4d + (15 + 3d) equivalent to (4d + 15) + 3d ?
Answer:
Yes it is
Step-by-step explanation:
4d + 3d = 7d so 7d + 15 would be the expression for both except it would only be 3d + 4d = 7d and 7d + 15 is the same as the first expression that I got from evaluating 4d + (15 + 3d).
______________________________
1.) Solve [tex]\bold{4d+(15+3d)}[/tex]:Combine 4d and 3d: [tex]=7d+15[/tex]2.) Solve [tex]\bold{(4d+15)+3d}[/tex]:Combine 4d and 3d: [tex]=7d+15[/tex]3.) Compare:[tex]7d+15=7d+15[/tex]

A bottled water company runs a promotion in which 1 out of every 4 bottles has the word "Winner" printed under the
cap. Winners receive a free bottle of water. A store owner notices that in the last 4 bottles of water purchased, 2
have been winners. Using the table, what is the probability of getting 2 or more "Winner" caps on 4 bottles of water?
Answer:
0.262
Step-by-step explanation:
Edge 2021
The probability of getting 2 or more "Winner" caps on 4 bottles of water
is 0.2616.
What is a binomial distribution in probability?In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability.
The binomial probability is, [tex]^nC_xP^xq^{n - x}[/tex].
Let, p be the probability of winning,
Given, 1 out of every 4 bottles has the word "Winner".
Therefore, p = 1/4 and we know q = 1 - p = 3/4.
So, The probability of getting 2 or more "Winner" caps on 4 bottles of water
is P(X ≥ 2) which is, P(X = 2) + P(X = 3) + P(X = 4).
P(X ≥ 2) = [tex]^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].
P(X ≥ 2) = 6(1/4)²×(3/4)² + 4(1/4)³×(3/4) + 1(1/4)⁴×1.
P(X ≥ 2) = 0.2109 + 0.0468 + 0.0039.
P(X ≥ 2) = 0.2616 or 26.16%.

Answer:
30
Step-by-step explanation:
Add all the measures 50+35+85+65+60= 210
subtract 180 from 210 and you get
210-180 = 30
we use 180 because Example: Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.

What is 8.478 in expanded form?
The expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)
What is an expanded form of numbers?We break up a number according to its place value and expand it to show the value of each digit, this process is called the expansion of the numbers.
Given that, we are asked to find the expanded form of 8.478,
The expanded form is :-
8 = 1 place = 8×1
0.4 = 1/10 place = 4×1/10
0.07 = 1/100 place = 7×1/100
0.008 = 1/1000 place = 8×1/1000
Therefore,
8.478 = 8×1+4×1/10×7×1/100+8×1/1000
Hence, the expanded form of the given number is 8×1+4×1/10×7×1/100+8×1/1000 (option c)

[tex]\sqrt{(-81)x^{2} }[/tex]
Answer:
We conclude that:
[tex]\sqrt{\left(-81\right)x^2}=9ix[/tex]
Step-by-step explanation:
Given the radical expression
[tex]\sqrt{\left(-81\right)x^2}[/tex]
simplifying the expression
[tex]\sqrt{\left(-81\right)x^2}[/tex]
Remove parentheses: (-a) = -a
[tex]\sqrt{\left(-81\right)x^2}=\sqrt{-81x^2}[/tex]
Apply radical rule: [tex]\sqrt{-a}=\sqrt{-1}\sqrt{a},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]
[tex]=\sqrt{-1}\sqrt{81x^2}[/tex]
Apply imaginary number rule: [tex]\sqrt{-1}=i[/tex]
[tex]=i\sqrt{81x^2}[/tex]
Apply radical rule: [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]
[tex]=\sqrt{81}i\sqrt{x^2}[/tex]
