A. The equation of the line is y = 1/2x
B. Sasha can make 60 gift bags in 2 hours.
C. The constant of proportionality is l = 1/2
D. Sasha can make 2 bags per minute.
Answers
Answer:
D
Step-by-step explanation:
The reason D is false is because it states that Sasha can make 2 bags per minute while she cant make 2 bags per minute. She can make half a bag per minute. D is wrong 100%
Answer:
Step-by-step explanation:
Distance covered = speed × time.
Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour.
This means distance covered while running would be
3.8 × 1/2 = 1.9 meters
Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. This means distance covered while walking would be
1.5 × 1/2 = 0.75 meters
Total distance that Sasha covered while running and walking in 60 minutes would be
1.9 + 0.75 = 2.65 meters

Given data,

Here, we want to get the scale factor
Define Scale factor :
Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures.
To get the scale factor, we divide corresponding sides by each other
That, we have that,

= 9.5 / 19
= 0.5 (see image)

o=19*19
o=361
t=19/2 * 19/2
t=19*19/(2*2)
t=361/4
t=o * x

Step-by-step explanation:
The options are:
A.There is no way to compare these heights
B.Mount Everest is about 40 times as tall as the Empire State Building
C.Mount Everest is about 23 times as tall as the Empire State Building

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answers
The slope of the line is m = 14 / 17
The slope of a line is that the magnitude relation of quantity the quantity the number that y will increase as x will increase some amount. Slope tells you ways steep a line is, or what proportion y will increase as x will increase. The slope is constant (the same) anyplace on the road.Slope = rise/runIf y represents the vertical direction on a graph, and x represents the horizontal direction, then this formula becomes:Slope = (Change in y)/(Change in x)The line representing "rise" and " run" is given below
The vertical distance is said to be "rise" and from the graph it is equal to 14.
The horizontal distance is said to be "run" and from the graph it is equal to 17 .
According to the slope formula , we get
m = 14 / 17

Answer:1

The slope of the line through C(2, 5) and D(4,7) will be 1.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
Then the slope of the line through C(2, 5) and D(4,7) will be given as,
m = (y₂ - y₁) / (x₂ - x₁)
m = (7 - 5) / (4 - 2)
m = 2 / 2
m = 1
Thus, the slope of the line through C(2, 5) and D(4,7) will be 1.

O fx) = 2(x + 4)(« + 4)(« + 4)(-10)
O f) =3K – 4)(«-4)0x + 10)
O f()= 3(x + 4)(x + 4)(K- 10)
Answers
Answer:
f(x) = 2(x+4)(x+4)(x+4)(x-10)
Step-by-step explanation:
Here, we want to write a polynomial function with leading coefficient of 2, root - 4 with multiplicity 3 ( meaning it appears 3 times);
and root 10 with multiplicity 1
If x = -4
Then in linear form, we have x + 4
if x = 10, in linear form, we have x -10
So the polynomial is;
f(x) = 2(x+4)(x+4)(x+4)(x-10)

A group of 12 friends are in line to see a play. It cost $15 for 4 people to see a play. How much will the group pay?
Answers
Answer:
$45
Step-by-step explanation:
3x4=12
15x3=45
ANSWER: $45!
Explanation: Okay so first, there are 12 friends and $15 per 4 of each friend! First we will make it easier by finding the original cost of 1 friend or a term called the mean! So to find the mean we will divide 15 by 4 which is ($3.75) so that means for one person it’s $3.75 so now that we have the mean we can check if it will give us a total of 15! So now 3.75 x 4= 15 so our mean is correct! Now it is easier! We can multiply 3.75 by 12 and that is 45! So your answer would be the group of friends will pay ($45) this is the more sufficient way but another more elementary style way is to do 12 divided by 4 which is 3 then next you will do, 15 x 3= 45 because, if there are 12 friends and $15 per four friends we will have to divided the 12 by 4 to find how much more groups of 4 friends needed! So after we got our total 3 we needed to multiply it by 15 because $15 is per 4 friends so we only needed three groups of 4 friends to get our answer!!
Hopefully this was not confusing in any way! Enjoy your day :)

nature of all roots for this function?
A) f(x) has two real roots and one imaginary root.
B) f(x) has three real roots.
C) f(x) has five real roots.
D) f(x) has three real roots and two imaginary roots.
Answers
Answer:
D.
Step-by-step explanation:
Its a fifth degree function so it will have 5 roots.
One of the 3 roots is complex ( imaginary):- 4 + i so there must be another root value 4 - i because these roots always occur as conjugate pairs.
The fifth root must be real because you cant have just one imaginary root.
