Find the value of k given that both points lie on a line passing through the origin.
(k,−24) and (5,40)
PLEASE HELP ASAP if you do thank u and have a blessed day
Answer:
[tex]k=-3[/tex]
Step-by-step explanation:
Since the line passes through the origin, it must be a proportional/direct variation equation.
Direct variation equations have the form:
[tex]y=ax[/tex]
Where a is the constant of proportionality.
Let’s solve for a. We know that when x=5, y=40. So:
[tex]40=5a[/tex]
Divide both sides by 5:
[tex]a=8[/tex]
Therefore, our equation is:
[tex]y=8x[/tex]
We want to find the value of k such that y=-24. So, subsitute -24 for y and k for x:
[tex]-24=8k[/tex]
Divide both sides by 8:
[tex]k=-3[/tex]
Hence, the value of k is -3.

What is the equation of the line that passes through the point (-3, 4) and has a slope of 1/3?
Answer:
y = 1/3x + 5
Step-by-step explanation:
y - y1 = m(x - x1)
y - (4) = 1/3(x - (-3)
y - 4 = 1/3(x + 3)
y - 4 = 1/3x + 1
y = 1/3x + 1 + 4
y = 1/3x +5

A rectangular piece of plastic sheet measures 1m by 70cm.
find its cost at the rate of Rs. 80 per metre.
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
Area of Rectangular sheet = 1m X 0.7 m = [tex] 0.7m^{2}[/tex] or [tex]70 cm^{2} [/tex]
Rate = Rs.80 per [tex] meter^{2} [/tex]
= [tex] 0.7m^{2} \times 80 = 56 [/tex]
hence, The cost will be Rs. 56 for the plastic sheet.
Step-by-step explanation:
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m 2 ×80=56
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m 2 ×80=56hence, The cost will be Rs. 56 for the plastic sheet.

Of the 200 students in the school, 79% can play an instrument. How many students cannot play an instrument? help pls
Answer:
158 students cannot play an instrument
Step-by-step explanation:
x/200=79/100
79*200=15800
15800/100=158
158/200=0.79 or 79%
Suppose A and B are points on the number line. If AB = 8 and B lies at −7, where could A be located?
Select ALL that apply.
−1
1
15
−15
Answer:
The correct answers are: 1 and -15
Step-by-step explanation:
Let a be a point on number line and b be the second point on number line.
The distance between two numbers on number line is calculate by subtracting the smaller number from larger number.
Here
AB = 8
B = -7
We have to look at the options one by one.
For A = -1
As A>B
[tex]AB = B-A = -1-(-7) = -1+7 = 6[/tex]
For A = 1
As A>B so
[tex]AB = A-B = 1-(-7) = 1+7 = 8[/tex]
So with A = 1 , AB = 8
This is one of the right answers.
For A=15
As A>B
[tex]AB = A-B = 15-(-7) = 15+7 = 22\\[/tex]
For A=-15
As B>A
[tex]AB = B-A = -7-(-15) = -7+15 = 8[/tex]
As with A=1 and A=-15, the distance between AB is 8 so these are the correct answers.
Hence,
The correct answers are: 1 and -15

Which is the proportional relationship for this graph?
Answer:
For every the canoe is rented, the total cost goes up by $12.
Step-by-step explanation:
To find the proportional relationship, Take two points from the graph, for example (2, 24) and (4, 48), and put them into the slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{48-24}{4-2}[/tex]
Solve:
48 - 24 = 24
4 - 2 = 2
24/2 = 12
The proportional relationship between the hours the canoe is rented and the total cost is $12.
Hope this helps :)
The art teacher is going to have students
paint a mural on the wall of the school.
The building is 632.5 feet long, and there
are 73 students. Part of the wall can't be
painted because it has doors in it; this
part of the wall is 12 feet long. How wide
is the area that each student will have to
paint?
Answer:
8.5 feet
Step-by-step explanation:
632.5-12= 620.5
620.5/73=8.5
what is the measure of angle x?
Answer:
the answer is 111
Step-by-step explanation:
[tex]180 - 36 - 75 = 69[/tex]
[tex]180 - 69 = 111[/tex]
Answer:
x = 111°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, thus
x = 75° + 36° = 111°
3(x + 1) = −2(x − 1) − 4
$25 with a 300% increase
Answer:
100 dollars
Step-by-step explanation:
So amount of increase = (300/100) * 25
= 3 * 25
= 75 dollars
Then the final amount = (25 + 75) dollars
= 100 dollars

The linear function graphed below represents Brenda’s monthly cell phone bill based on the number of hours she uses. What is her hourly rate? A graph titled Brenda's Monthly Cell Phone Bill has hours used on the x-axis and cell phone bill (dollars) on the y-axis. Points plotted are (1, 27), (2, 39), and (3, 51). $12 per hour $15 per hour $27 per hour $39 per hour
Answer:
$12 per hour
Step-by-step explanation:
In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's use the points (1, 27) and (2, 39) in the expression:
[tex]\frac{39 - 27}{2 -1}[/tex]
Now let's simplify the expression:
39 - 27 = 12
2 - 1 = 1
The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.
I hope this helps :)
Answer:
12$ per hour!

In which of the following functions would it be appropriate to use only positive integers for the domain? Select all that apply.
1.The function c(p) represents the cost for (p) people to attend the movies.
2.The function m(t) represents the miles driven over t hours.
3.The function t(m) represents the average high temperature for a given number of months.
4.The function p(w) represents the profit of a farmer who sells (w) whole watermelons.
5.The function h(n) represents the number of person-hours it takes to assemble (n) engines in a factory.
Answer:
2-The function m(t)represents the miles driven over t hours.
The following would be appropriate for integers. That means that we don't have any decimals or fractions.
The number of people attending a movie, there are no half people.
The number of watermelons sold by farmers, they don't grow half watermelons.
