I just need to know the slope and the y-intercept of the equation, thanks!
Answer:
Slope is [tex]\frac{1}{4}[/tex] and intercept is -2.
Step-by-step explanation:
Slope if the multiplied before the x (so [tex]\frac{1}{4}[/tex]).
Intercept is the standalone number (so -2).
Solve for x. 18 ÷ x = -2 x =

A submarine was cruising at 1,328.4 feet below sea level. It then rose at a rate of 14.76 feet per minute for 15 minutes. Find the submarines depth after it rose for 15 minutes.
Answer:
New depth = 1,107 feet
Step-by-step explanation:
1) Let us first calculate the total number of feet the submarine rose in 15 minutes using the rate of rise.
rate = 14.76 feet per minute
This means that at every minute, the submarine rose by 14.76 feet.
1 minute = 14.76 feet
∴ 15 minutes = 14.76 × 15 = 221.4 feet
2) To find the new depth, we will subtract the number of feet risen from the initial depth.
initial depth = 1,328.4 feet
rise after 15 minutes = 221.4 feet
New depth = 1,328.4 - 221.4 = 1,107 feet
In AXYZ, P is the centroid and YC = 15.
Find the length of YZ
PLEASE HELP!
Answer:
YZ = 30
Step-by-step explanation:
In Δ XYZ
∵ P is the centroid
∴ XC, YB, and ZA are the medians of the triangle
∵ Each median bisects its base
∴ A is the mid-point of XY
∴ B is the mid-point of XZ
∴ C is the mid-point of YZ
∵ C is the mid-point of YZ
∴ YC = ZC
∵ YC = 15
∴ ZC = 15
∵ YZ = YC + ZC
∴ YZ = 15 + 15
∴ YZ = 30
∴ The length of YZ is 30

ra\\For spirit week at a local high school, students were encouraged to wear their school colors of green and white. 1,200 students wore their school colors while 300 students did not wear green and white. What percent of the school population did NOT wear their school colors?
Answer:
20%
Step-by-step explanation:
First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.
Answer:
25%
Step-by-step explanation:
1. You have a total of 1,200 students and a fraction of them did not wear their school colors, 300 students.
2. You would write the fraction [tex]\frac{300}{1200}[/tex].
3. After you divide or simpify [tex]\frac{300}{1200}[/tex] you get [tex]\frac{1}{4}[/tex].
4. To get a percent you multiply by 100, so [tex]\frac{1}{4}[/tex] times 100 is equal to 25.

Yeast , a key ingredient bread , thrives within the temperature range of 90° F to 95°F . Write and graph an inequality that represents the temperatures where yeast will NOT thrive .
Answer:
Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive
Step-by-step explanation:
The given parameters are;
The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F
Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y and y > 95°F
The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.
Answer:
Picture shown below
Step-by-step explanation:
Yeast thrives in temperatures within the temperature range of 90°F to 95°F. Any temperature above or below those limits hinders yeast production. An inequality to represent where yeast will not thrive is shown, where x represents the temperatures where the yeast will not thrive.
Emily spent £2400 on holiday in 2017.
This was 20% more than she spent on holiday in 2016.
Calculate the amount she spent on holiday in 2016.
Answer:
£1920
Step-by-step explanation:
The amount she spent in 2016 is 20% less than 2017. 20% less than is the same as 80% of the amount she spent in 2017. So, to find how much she spent in 2016, multiply 2400 by 0.80 (the decimal form of 80%):
2400 * 0.8 = 1920
Emily spent £1920 on holiday in 2016.

An equation in slope intercept form of the line shown (4,1) and (8,4) is y=3/4 x-2.
The given coordinate points are (4, 1) and (8, 4).
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Here, slope = (y2-y1)/(x2-x1)
= (4-1)/(8-4)
= 3/4
Put m=3/4 and (x,y)=(4,1) in y=mx+c
1=3/4 (4)+c
⇒c=-2
Now, substitute m=3/4 and c=-2 in y=mx+c and simplify
That is y=3/4 x-2
Therefore, an equation in slope intercept form of the line shown (4,1) and (8,4) is y=3/4 x-2.

rt - 2n = y solve for t
Answer:
[tex]t=\frac{y+2n}{r}[/tex]
General Formulas and Concepts:
Pre-Alg
Equality PropertiesStep-by-step explanation:
Step 1: Define equation
rt - 2n = y
Step 2: Solve for t
Add 2n to both sides: rt = y + 2nDivide both sides by r: t = (y + 2n)/rRod is paid $85 to install a screen door and $115 to install a wooden door. In one week he installed 18 doors and was paid a total of $1860. How many screen doors did Rod install?
Answer:Rod installed 7 screen doors
Step-by-step explanation:
Step 1
Let the number of screen door = x
And the number of wooden doors = y
since he installed 18 doors , we have that
screen door + wooden doors = 18
x + y = 18------ equation 1
Also the cost to install a screen door -= $85
and to install a wooden door = $115
And he was therefore paid a total of $1850
Therefore
85x + 115 y = $1860------- equation 2
Step 2----- Solving
x + y = 18------ equation 1
85x + 115 y = $1860------- equation 2
Multiplying equation 1 BY 85
85x + 85y= 1530------- equation 3
85x + 115 y = $1860------- equation 4
subtracting from equation 1 from (2)
115y- 85y= 1860-1530
30y=330
y = 330/30 = 11
To find x
x+ y=18
x= 18-y
x= 18-11= 7
Rod installed 7 screen doors and 11 wooden doors.

Answer:
11: 2
12: 4
Step-by-step explanation:
11: the rate of change is the slope, which is the rise/run, so it is in this case 2/1, which simplifies to 2
12: again, using rise/run method, go down two spaces and left one (since the slope is 2/1,) which takes you to (0,4), and since the y-value is 4, the y-intercept is 4

8 1/4 pounds of flour are used to make 4 1/8 papier-mâché pasta recipe how much flour is used in one recipe
Answer:
1/6
Step-by-step explanation:
ive seen that question b4
2 pounds of flour are required to make 1 recipe, as of the given condition.
Given that
8 1/4 pounds of flour are used to make 4 1/8 paper-mâché pasta recipe how much flour is used in one recipe is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Flour = 8 1/4
Flour = 8.25 pounds
The proportion of the recipe made corresponding to 8.25 pounds of flour = 4.125
Now,
For 1 recipe = 8.25 / 4.125 = 2 pounds of flour are needed.
Thus, 2 pounds of flour are required to make 1 recipe, as of the given condition.
