Answer:
This is a problem of 2 equations with 2 unknowns.
A general equation of a line is y = mx + b, and in this case the unknowns I refer to are m and b.
Since 2 points on the line are given, I can plug one of those into the equation to come up with an equation in 1 unknown; then use the 2nd point to determine the last unknown.
So…using (5,2), 2 = 5m + b or b = 2 - 5m.
Now, using this value for b, I use the 2nd point (-5,7), as follows:
7 = -5m + 2 - 5m or -10m = 5, so…m = -1/2
If b = 2 - 5m, then b = 4 1/2
So the equation of the line Vikas is looking for is:
y = -1/2 x + 4 1/2

Answer:
n=100+0.05(460)
Step-by-step explanation:
She earns 100 dollars all the time. so its 100+ something
she also earns 5% of the tips, which in that case were 460$
you can repersent that as 0.05(460)
so: 100+0.05(460)

A manufacturer claims that their cans of paint contain exactly 130 fluid ounces of paint. The amount of paint in each can of paint must be accurate within ±3.05 fluid ounces of the actual amount of paint. a. Write an absolute value inequality to represent the possible amount of paint, in fluid ounces, p for which the manufacturer’s claim is correct. b. Graph the solution set of the inequality you wrote in part a.
Answer:
3.0232 ounces per can of paint and 43 cans in 130 ounces of fluid
Step-by-step explanation:
130 ounces of fluid divided by ±3.05 and for me it was easier to reach by approximation
Is -1.2 greater than 0.8?
Answer:
no
Step-by-step explanation:
a negative value is never greater than a positive one
Answer:
No
Step-by-step explanation:
-1.2 is a negative number which means it is subtracted, but 0.8 is a fraction of 1, while -1.2 is 1.2 less than one. So 0.8 is larger than -1.2
1. Identify the equation that has the same slope as the points (0, -3) and (-1, 1)
1. y= 3x+2
2. y= -4x-3
3. y= x+1
4. y= -x+2
Answer:
2. y= -4x-3
Step-by-step explanation:
y=mx+b
slope :m
(0,-3) : m.0+b=-3 => b=-3
(-1,1) : m.1+b= 1 => m=-4

Answer:
median = 9.5
range = 11
Step-by-step explanation:
mean = (sum of numbers)/(number of numbers)
(18 - x + x - 3 + x + x/2 + 5 + 4x - 10 + 2x - 1)/6 = 9
9 + 7x + x/2 = 54
7x + x/2 = 45
14x + x = 90
15x = 90
x = 6
Now we can write the 6 numbers.
12, 3, 6, 8, 14, 11
We write the numbers is increasing order.
3, 6, 8, 11, 12, 14
The median is the mean of the 2 middle numbers.
median = (8 + 11)/2 = 19/2 = 9.5
The range is the difference between the larges and smallest of the numbers.
range = 14 - 3 = 11

In a shop, the normal price of a coat is £65.
The shop has a sale.
In week 1 of the sale, the price of the coat is reduced by 20%
In week 2 of the sale, the price of the coat is reduced by a further £10.
Maria has £40.
Does Maria have enough money to buy the coat in week 2 of the sale?
You must show how you get your answer.
Answer:
hope this helps plz mark brainliest
Step-by-step explanation:
Hence Maria does not have enugh money to buy the coat in week 2 of the sale
Normal price of a coat : 65
As in week 1 of the sale = 65 - 20/100 x 65
= 65 - 13 = 52
Also in week 2 of the sale the price of the coat is reduced by a futher 10

A hardware store offers customers a coupon for $24 off.
The regular price of a power drill is $96.
If a customer uses the coupon, what percent will the customer save?
Your answer is : (blank) %
Answer:
25%
Step-by-step explanation:
Divide 24 and 96:
24 ÷ 96 = 0.25
Now move the decimal point in 0.25 two times:
0.25
Let f(x) = x*g(h(x)) where g(4) = 2, g'(4) = 3, h(3) = 4, and h'(3) = -2. Find f'(3).
By the product and chain rules,
f'(x) = g(h(x)) + x g'(h(x)) h'(x)
Then
f'(3) = g(h(3)) + 3 g'(h(3)) h'(3)
f'(3) = g(4) + 3 g'(4) (-2)
f'(3) = g(4) - 6 g'(4)
f'(3) = 2 - 6(3)
f'(3) = -16
Jessica can walk 1.5 kilometers in 30 minutes. How long will it take her to walk 2.5 kilometers?
Answer:
It will take her 50 minutes in total to walk 2.5 kilometers.
Step-by-step explanation:
You first start off by finding how long it take to walk 1 kilometer. In this case it takes 20 minutes to walk 1 kilometer. Then multiply 20 times 2.5. You then receive your final answer... 50 minutes.

Answer:
Step-by-step explanation:
Write the equation of a line that is perpendicular to x=5.
Write the equation of a line that is parallel to 4x+3y=1.
Write the equation of a line that is perpendicular to x-5y=2
Write the equation of a line that is perpendicular to x=5.
x=5 is a straight line going through 5 on the x axis. A line perpendicual to this will be any line parallel to the x axis. This would mean y=[Any Number]. Pick what you want for [Any Number}, but I'll choose my lucky number, 6.
y =6
Write the equation of a line that is parallel to 4x+3y=1.
A parallel line have the same slope, so we can start by rewriting the equation in standard form of y=mx + b, where m is the slope and b the y-intercept (the value of y when x=0):
3y = -4x + 1
y = -(3/4)x + (1/3)
The slope is -(3/4), so the new line will also have the nsame slope. Start by putting -(3/4) in the satandard format:
y = -(3/4)x + b
In the absence of any other information, we are free to pick whatever value we want for b, as long as it is not 1. I'll choose . . .
y = -(3/4)x + 6
Write the equation of a line that is perpendicular to x-5y=2
As before, rewrite into standard form:
-5y = -x + 2
y = (1/5)x + 2
A perpendicular equation will have a slope that is the negative inverse of the reference line. The negative inverse of (1/5) is -5. Now we have:
y = -5x + b
Since we aren't given any addition information, we can pick any b we want.
y = -5x + 6

(x)=4(x+3)(3x-8) in standard form
Answer:
12x² +3x = 96
Step-by-step explanation:
x = 4(x + 3)( 3x - 8)
x = (4x + 12) (3x - 8)
x = 4x(3x - 8) + 12(3x - 8)
x = 12x² - 32x + 36x - 96
x = 12x² + (-32x + 36x) - 96
x = 12x² + 4x - 96
0 = 12x² + 4x -x - 96
0 = 12x² + 3x -96
96 = 12x² + 3x same as 12x² +3x = 96

Write down the equation of a line whose slope is 5 and crosses the y-axis at -6. Express in slope-intercept form.
Answer:
Y= 5x-6
Step-by-step explanation:
The slope intercept form is y=mx+b. The m stands for your slope. The b stands for the y-intercept. So, plug in the slope of 5 for m, then plug in -6 of b and then your equation should end up as y=5x-6. Hope this helps :)
