Answer:
y = 2x - 1.
Step-by-step explanation:
The slope = (7-3)/(4-2)
= 4/2
= 2.
y - y1 = m(x - x1)
Here m = 2 , x1 = 2 and y1 = 3. So we have:
y - 3 = 2(x - 2)
y = 2x - 4 + 3
y = 2x - 1.
We have used the point (2, 3) to find the equation but we could have used (4, 7). We would have got the same answer.
Answer:
y - 3 = 2(x - 2)
Step-by-step explanation:
As we move from Point B (2, 3) to Point A (4, 7), we see x increasing by 2 from 2 to 4 and y increasing by 4 from 3 to 7. Hence the rise is 4 and the run is 2, which means that the slope of this line is m = rise / run = 4/2 = 2.
Using the point-slope formula y - k = m(x - h) and the point (2, 3), we get:
y - 3 = 2(x - 2)
What is the y-intercept for the line at the right? _________ .What is the slope of the line? __________ .Write the equation of the line in slope-y intercept form.

You have a box with 5 blue marbles, 4 red marbles, and 9 yellow marbles. You are going to pull out one marble, record its color, put it back in the box and draw another marble. What is the probability of pulling out a blue marble followed by a yellow marble?
Answer:
I think it's 45/196.
Step-by-step explanation:
Not sure though, no explanation.
The probability of pulling out a blue marble followed by a yellow marble 25% or 0.25 .
What is probability ?
Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
Based on the given conditions, formulate 9 ×9÷((9 + 5 + 4) ×(9 +5 +4))
Calculate the product or quotient = [tex]\frac{81}{(9 +5 + 4) * (9 + 5 + 4)}[/tex]
Calculate the sum or difference= [tex]\frac{81}{(14 + 4) * (9 +5+4)}[/tex]
Calculate the sum or difference = [tex]\frac{81}{18 * (9+5+4)}[/tex]
= [tex]\frac{81}{18 * (14 + 4)}[/tex]
=[tex]\frac{81}{18 * 18}[/tex]
Calculate the product or quotient = [tex]\frac{81}{324}[/tex]
Cross out the common factor = [tex]\frac{1}{4}[/tex]
get the result 25% or 0.25
Therefore, The probability of pulling out a blue marble followed by a yellow marble 25% or 0.25 .

The answer would be 1/6 IF you took 1/6 of the full sheet of paper, but if you are taking 1/6th of half of the paper, then you are taking half the amount. Basically, you would need two 1/6 pieces of one half to be equivalent to one 1/6th piece on the full sheet.

A clock is divided into two equal parts.
(1) 1 - 6
(2) 7 - 12
When the hour hand is on (1), then the time is "after"
When the hour hand is on (2), then the time is "before"
From the attached clock, we have:
(1) The hour hand on 9
(2) The minute hand 1 unit above 9 i.e. 46 minutes
(1) implies that, the time is before 9 i.e. past 8
(2) implies that the minutes is (60 - 46) before 9 or 46 minutes after 8
In (1) and (2) above, we have two interpretations.
1: (60 - 46) minutes before 9
This gives:
14 minutes before 9
2: 46 minutes past 8
i.e. 8 : 46

Jade has tax deducted from her income at the rate of 24%.
Last month, after tax had been deducted, $1786 of her income remained.
Calculate her income last month before the tax was deducted.
Answer:
$2350
Step-by-step explanation:
Let Jade's total income be X
Therefore,the tax deducted was 24%x
Forming an equation:
X= 24%x + 1786
X = 0.24x + 1786
Collecting like terms
x - 0.24x = 1786
0.76x =1786
x= 1786 ÷0.76
X= $2350
Carolina is mowing the lawn for a summer job. For each cutting job, she charges an initial fee of $ 8 plus $ 6 for each hour of work. 1-Write an equation (in the form y = mx + b) to represent this problem. 2-If Carolina is paid a total of $ 32, how many hours did she work?
Answer:
F(t) = 8 + 6(t)
Step-by-step explanation:
6*4 = 24
32-24 = 8
so her initial fee is $8
so function is:
F(t) = 8 + 6(t)
Answer:
1. y = 6x + 8
2. 4 hours.
Step-by-step explanation:
x is each hour of work.
y is the total that Carolina is paid.
y = mx + b
32 = 6(x) + 8
Subtract 8 from both sides.
6x = 32 - 8
6x = 24
Divide both sides by 6.
x = 4
Carolina is works 4 hours to be paid 32.
A 16-cup container of laundry detergent costs $13.60. What is the price per quart?
Answer:
$0.21
Step-by-step explanation:
So, first let's find the cost of a single cup.
16/13.60 = 1/0.85
Now, we know that each cup is approximately $0.85. Next, we must convert cups into quarts. 1 cup = 0.25 quarts.
1/0.85 = 0.25/0.21

Answer:
V = 1020.5 yd³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h( r is the radius and h the height )
Here r = 5 and h = 13 , then
V = π × 5² × 13
= 3.14 × 25 × 13
= 1020.5 yd³
Find the equation of the circle with a center at (2,-1) and a radius of square root of 12
Answer:
[tex]x^{2}[/tex]+ [tex]y^{2}[/tex] -4x+2y-7=0
Step-by-step explanation:
Given that, center at (2,-1)
let a = 2, b = -1
radius, r = [tex]\sqrt{12}[/tex]
As we know the equation circle is, [tex](x-a) ^{2}[/tex]+[tex](y-b) ^{2}[/tex] = [tex]r^{2}[/tex] when radius and center point is given.
By this formula , we can get,
[tex](x-2) ^{2}[/tex]+[tex](y-(-1)) ^{2}[/tex] = [tex]\sqrt{12} ^{2}[/tex]
[tex]x^{2}[/tex] -4x +4 + [tex]y^{2}[/tex] + 2y + 1 = 12
[tex]x^{2}[/tex]+ [tex]y^{2}[/tex] -4x+2y-7=0
This is the answer.

David has $520 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax.
• He buys a new bicycle for $303.93.
• He buys 4 bicycle reflectors for $10.99 each and a pair of bike gloves for $25.25.
• He plans to spend some or all of the money he has left to buy new biking outfits
for $73.43 each.
Write and solve an inequality which can be used to determine x, the number of
outfits David can purchase while staying within his budget.
Step-by-step explanation:
after he buys everything he has 170.83 ( total 340.17) 73.43 times x
8x−2=−11+7x +2
Please help me!!
Answer:
x=-7
Step-by-step explanation:
8x - 2 = -11 + 7x + 2
First, separate the terms: move x to one side
subtract 7x from both sides
8x -7x - 2 = -11 + 7x -7x + 2
x - 2 = -11 + 2
Now get x by itself by adding 2 to both sides
x - 2 +2 = -11 + 2 +2
x = -11 + 4
simplify
x = -7
you're welcome
