Answer:
y = 2x - 3
Step-by-step explanation:
We are given the slope, m = 2
Our standard formula of a line is y = mx + b, so we can substitute for the x and y values of the point (3, 3). If you did not know, the x-value and the y-value are both 3 because the point (3, 3) = (x, y).
So, our equation looks like this:
3 = (2)(3) + b
We can solve for b:
3 = 6 + b
b = -3
And now we have our equation of a line:
y = 2x - 3

One bag contains black, red and green pearls in a ratio of 3: 2: 7 A random account is drawn from the bag. Exercise routine a P (red)
Answer:
P(red) = 1/6
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
One bag contains black, red and green pearls in a ratio of 3:2:7.
So
[tex]\frac{3}{3+2+7} = \frac{3}{12}[/tex] of the pearls are black
[tex]\frac{2}{3+2+7} = \frac{2}{12}[/tex] of the pearls are red.
[tex]\frac{7}{3+2+7} = \frac{7}{12}[/tex] of the pearls are green.
P (red)
For each 12 pearls, 2 are red. So
P(red) = 2/12 = 1/6

A parabola can be drawn given a focus of (-10,1) and a directrix of x = -6. What can be said about the parabola?
Answer:
The characteristics of the parabola are;
1) The vertex of the parabola, (h, k) = (-8, 1)
2) The parabola opens left
3) The axis of symmetry is, y = 1
4) The equation of the parabola is x = -y²/8 + y/4 - 65/8
5) The end points of the latus rectum are (-10, -3), and (-10, 5)
Step-by-step explanation:
The focus of the parabola = (-10, 1)
The directrix of the parabola, x = -6
The directrix; x = h - p
The focus, F(h + p, k)
Therefore, we have;
h + p = -10
h - p = -6
2·h = -16
h = -8
p = -10 - h = -10 - (-8) = -2
p = -2
Therefore, we have;
1) The vertex of the parabola, (h, k) = (-8, 1)
2) Therefore, the parabola opens left
3) The axis of symmetry is the line y = 1
For P < 0, the equation of the parabola is of the form (y - k)² = 4·p·(x - h)
Therefore, the equation of the parabola is (y - 1)² = 4×(-2)×(x - (-8))
(y - 1)² = 4×(-2)×(x - (-8)) = y² - 2·y + 1 = -8·x - 64
∴ y² - 2·y + 1 + 64 = -8·x
x = -y²/8 + y/4 - 65/8
4) The equation of the parabola is x = -y²/8 + y/4 - 65/8
5) The end points of the latus rectum are (h + p, k + 2·p) and (h + p, k - 2·p)
Therefore, the end points of the latus rectum of the given parabola are;
(-8 + (-2), 1 + 2×(-2)) and (-8 + (-2), 1 - 2×(-2))
(-10, -3), and (-10, 5)

Which inequality represents the stated situation : A theater is made to receive no more than 750 spectators. Group of answer choices
Answer:
C. s ≤ 750
Step-by-step explanation:
A. s≥750
B. s=750
C. s≤750
D. s<750
'no more than' in inequality means "less than or equal to"(≤) which means that the quantity could be less than or equal to.
From the question given, the theater can only receive less than 750 spectators or 750 spectators but no more than 750 spectators
The statement can be represented by the inequality;
s ≤ 750
Where
s means spectators

Answer:
4 lbs left after 5 days
Step-by-step explanation:
First, you need to step up an equation!
You know that Soomin has a total of 20 pounds and that she's using it, so you are going to use subtraction.
She uses 3 1/5 pounds per day so you write:
20 - 3 1/5x
and you know that she wants to know how much she has left after 5 days so you replace the x with 5:
20 - (3 1/5) * 5
Multiply first:
20 - 16
After Subtracting you get the answer:
4 lbs left
Answer:
4 lbs
Step-by-step explanation:
If she gives 3.2 each day you can multiply by 5 to get 16 then subtract 20 - 16 to get 4
find the value of each variable. please help this is overdue
Answer:
x = 16√3
y = 8√3
Step-by-step explanation:
First, to figure out x, put the side we already know (24) over the cosine of the angle we know (30).
x = 24/cos(30)
(cos(30) is the same as √3/2)
x = 24/√3/2
Step 1: Multiply by 2/√3
x = (24 * 2)/√3
Step 2: Rationalize the denominator by multiplying by √3
x = √3(24 * 2)/√3 * √3
Step 3: √3 squared is 3.
√3(24 * 2)/3
Step 4: Multiply 24 by 2 to get 48.
x = √3(48)/3
Divide √3(48) by 3 to get 16√3
x = 16√3
Before we figure out y, we need to find you what 16√3 squared is.
((16(√3))²
Step 1: Expand the above equation.
16²(√3)²
Step 2: Square 16 to get 256.
256(√3)²
Step 3: √3 squared is 3.
256(3)
Step 4: Multiply 256 by 3 to get 768.
768
Now, subtract 576 (24 squared) from 768 to get 192. Find the square root of that, which is 8√3. (192 = 8² * 3; rewrite as √8²√3, then take the square root of 8²

A county planner is looking at trends in population growth for two towns, Hapville and Merton. The population of Hapville in the year 2000 was 18,000. Since then, the population has increased at a steady rate of 500 per year. The population of Merton is increasing according to the equation y=12,000(1.04)t , where y = the population in thousands and t = the number of years since the year 2000. If these trends continue, how will the populations of the two towns compare in 2030?
Answer:
Merton will have about 6,000 more people than Hapville
Step-by-step explanation:
Merton
y = 12,000(1.04)^(30)
y = 12,000(3.24339)
y = 38,920.77012
Hapeville
y = 18,000 + (30 x 500)
y= 18,000 + 15,000
y = 33, 000
Merton - Hapeville
38,920.77012 - 33,000 = 5920.77012
Therefore Merton will have about 6,000 more people than Hapville

7 years ago father was 7 times as old as his son was. three years hence, he will be three times as old as his son find their present ages.
Answer:
son = 10 , father = 40
Step-by-step explanation:
Let Five years ago the age of son be x years and age of father be 7x years
Present age of son =x+5
Present age of father =7x+5
5 years later their age will (x+10) and (7x+10)
∴7x+10=3(x+10)
7x−3x=20
4x=20
x=5
So, the present age of son=x+5=5+5=10years
and the present age of father=7x+5=35+5=40years

For a circle of radius 7 feet, find the length of an arc s with a measure of 26°.
s = 7/180 π feet
s = 91/180 π feet
s = 182 π feet
s = 91/90 π feet
Answer:
Step-by-step explanation:
r = 7 ft
θ = (26/180)π = (13/90)π radians
arc length = rθ = 7×(13/90)π = (91/90)π ft

Kelly filled up her 14 gallon gas tank for $29.26. What if the tank is 17 gallons, how much does she have to pay?
Answer:
$35.53
Step-by-step explanation:
1. Divide what Kelly paid by the amount of gallons she paid for.
a. 29.26 divided by 14 = 2.09
2. Take the amount per gallon and multiply it by 17.
a. 17 times 2.09 = 35.53
So it will be $35.53 for 17 gallons of gas.
Answer:
35.53
Step-by-step;
So Kelly got 14 gallons of gas for 29.26. She is wondering how much it would be to fill it up to 17 gallons. So what you have to do is first find out how much the gas cost per gallon. so you would divide 29.26 by 14 to get 2.09. so now that you have how much it is per gallon all you have to do is multiply the amount per gallon {2.09} by 17. so when you multiply 2.09 by 17 you get 35.53. So Kelly had to pay 35.53 for a 17 gallon tank of gas!
Hope this helps you!
