Answer:
y = 5/4x - 9
Step-by-step explanation:
y = mx + b
when you plot 4, -4 you have your first clue and point. then go up 5 and right 4 or down5 and left 4. When you go down you will reach the y intercept. On the number- 9. So -9 is your y intercept which goes in b.
Since 5/4 goes in the mx since it is slope the answer is y = 5/4 - 9
Help please!!!! Thank you
The graph of a line goes through the points (-4,3) and (6,8). What is the equation of the line in slope-intercept form? Enter the correct answer in the box by replacing m and b with the appropriate values.
y=mx+b ?
Answer:
y= ½ x + 5
Step-by-step explanation:
[tex] (-4,3) \: (6,8). \\ x_1 = - 4 \\ y_1 = 3 \\ x_2 = 6[/tex]
[tex]y_2 = 8 \\ \frac{y - y_1}{x - x_1} = \frac{y_2 -y_1}{x_2 - x_1} [/tex]
[tex] \frac{y - 3}{x - ( - 4)} = \frac{8 - 3}{6 - ( - 4)} = \frac{y - 3}{x + 4} = \frac{5}{10} [/tex]
[tex]10(y - 3) = 5(x + 4) \\ 10y - 30 = 5x + 20 \: \\ 10y = 5x + 20 + 30 = 10y = 5x + 50 \\ [/tex]
[tex] \frac{10y}{10} = \frac{5}{10} x + \frac{50}{10} \\ y = \frac{1}{2} x + 5[/tex]
A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line can be written as y = (1/2)x+5.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
To write the equation of the line, we need to firstly find the slope of the equation. Therefore, the slope of the equation can be written as,
Slope = (8 -3)/[6 - (-4)] = 5/10 = 1/2
Now, substitute the value of the slope and the any point in the general equation of a line. Therefore, we can write,
y = mx + c
8 = (1/2)(6) + C
8 = 3 + C
C = 5
Hence, the equation of the line can be written as y = (1/2)x+5.

Answer: Hi!
The value of the variable is 11.
The angles will be equal, as the lines intersect and make an X. To find the value of the angle, we would first subtract 2 from 35 and then divide by 3 to fill in the expression.
35 - 2 = 33
33 ÷ 3 = 11
The value of x is 11.

[tex] = \sqrt[5]{a^{5-2} b^{5-3}c^{5-4}}\\

Jennifer is going on a hike to the top of a mountain. It will take 3 hours and 55 minutes to hike up the mountain and 1 hour and 10 minutes to hike back down. If Jennifer wants to finish the hike by 3:45 P.M., what is the latest time she can start the hike up the mountain? Include A.M. or P.M. in your answer (for example, 11:58 A.M.).
====================================================
Explanation:
Add the minutes for now
55 minutes + 10 minutes = 65 minutes = 60 minutes + 5 minutes = 1 hour, 5 minutes
The minute portions add to 1 hour, 5 minutes. The hour portions add to 3+1 = 4.
Add on the "1 hour, 5 minute" portion and we get 5 hours, 5 minutes
This is the total duration of the round trip hike. Keep in mind that this does not include any time spent with Jennifer resting at the top of the mountain. This time duration assumes that once she gets to the top, she pretty much starts the hike back down the mountain.
----------------------------
Now convert 3:45 PM to military time. We add 12 hours to get 15:45
Subtract off 5 minutes to get 15:40
Then subtract off 5 hours to get 10:40, which converts back to 12-hour time notation to be 10:40 AM

A Girl Scout camp served half of their granola with breakfast. After dinner, they put the remaining 6{,}250 \text{ g}6,250 g6, comma, 250, start text, space, g, end text of granola on top of their yogurt dessert. How many kilograms of granola did the Girl Scout camp start with?
Answer:
12.5 kilograms
Step-by-step explanation:
Given:
Half of the granola served with breakfast.
Let the amount of Granola present initially = [tex]x[/tex] kg
Half of it ([tex]\frac{x}{2}[/tex]) served with breakfast, so remaining granola :
[tex]x-\dfrac{x}{2} = \dfrac{x}{2}[/tex]
After dinner, the remaining granola 6,250 gm granola was served with yogurt dessert.
First of all, let us convert it to kilogram because the answer is required in Kilograms.
We know that:
1000 gms = 1 kilograms
1 gms = 0.001 kilograms
6250 gms = 6250 [tex]\times[/tex] 0.001 = 6.250 kilograms
Now, as per given question statement:
[tex]\dfrac{x}{2} = 6.250\ kg\\\Rightarrow x = 2 \times 6.250\\\Rightarrow \bold{x = 12.5\ kg}[/tex]
So, the answer is:
Girl scout camp started with 12.5 Kilograms of granola.

Tony is 1⁄2 mile ahead of Laura on a jogging
path. If Tony is running at 4 miles per hour, and
Laura is running at 6 miles per hour, how long
will it take Laura to catch up with Tony?
Answer:
¼ hours or 15 minutes
Step-by-step explanation:
let the time it will for laura to catch up with Tony be 't'
Distance = speed × time
Distance corvered by Laura in time (t) = Distance corvered by Tony in time (t) + Distance between Tony and Laura
6×t = 4×t + ½
6t = 4t + ½
2t = ½
t = ¼ hours or 15 minutes
BRAINLIEST PLEASE
HOPE IT HELPS..... ;-)Answer:
15 minutes
Step-by-step explanation:
Let Tony is running x distance when Laura catch up him.
Then Laura is running x + 0.5 miles distance .
This motion takes the t time.
Using the equation of the motion ,
s = ut
s - Distance u - velocity t - Time
For Tony's motion
x = 4 × t --------*
For Laura's motion
x + 0.5 = 6 × t ------**
** - * --->
x + 0.5 - x = 6t - 4t
0.5 = 2t
t = 0.25 hours
t = 15 minutes

The diagram shows a rectangle ABCE.
D lies on EC.
DAB is a sector of a circle radius 8cm and sector angle 30º.
Calculate the area of the shaded region.
Answer:
15.25 cm²
Step-by-step explanation:
Step 1: find the width of the rectangle, AE.
[tex] cos(60) = \frac{EA}{8} [/tex]
[tex] 8*0.5 = EA [/tex]
[tex] 4 = EA [/tex]
[tex] EA = 4 cm [/tex]
Step 2: Find the area of the rectangle
[tex] Area_{rectangle} = length * width = 8*4 = 32 cm^2 [/tex]
Step 3: Find the area of the sector.
Take π as 3.14
[tex] Area_{sector} = \frac{30}{360}*3.14*8^2 [/tex]
[tex] Area_{sector} = \frac{30}{360}*3.14*8^2 = 16.75 cm^2 [/tex]
Step 4: Find the area of the shaded region.
Area of shaded region = [tex] Area_{Rectangle} - Area_{sector} = 32 - 16.75 = 15.25 cm^2 [/tex]

The following map shows the location of a mall, library, and school in a city: Mike traveled from the school to the mall and then from the mall to the library. Henry traveled from the school to the library. How many more miles did Mike travel than Henry?
A.) 10
B.) 12
C.) 34
D.) 46
Mike: From the school to the mall, we could count out 16 units. From the mall to the library, we could count out 29 units. When we add 16 and 29, we get the distance Mike traveled: 45 units.
Henry: He traveled from the school to the library. To find out how long this distance is, we look at our previous numbers. From the school to the mall: 16. From the mall to the library: 29
To solve, we need to know the Pythagorean Theorem. We use the formula a^2 + b^2 = c^2. Here, 16 is a and 29 is b. We need to square both numbers and add them together to get c^2.
[tex]16^2=256\\29^2=841\\256+841=1097\\1097=c^2[/tex]
Then, we have to square 1097 to find c.
√1097 ≈ 33
Total: We subtract Henry's distance from Mike's to get our final answer.
45 - 33 = 12
Mike traveled 12 more units than Henry.

What is the end behavior of the function h? H(x)=-4x+4
Answer:
Below
Step-by-step explanation:
The end behavior of a function is how it grows when it reaches both plus and - infinity.
To do that we will calculate:
● lim h(x) x=> +infinity = lim-4x+4 x=> +inf = lim -4x x=> +inf
-4 is negative so the limit will be -infinity
● lim (-4x+4) x=> -inf = lim (-4x) x=> -inf
-4 is negative, x is negative then -4x is positive. So the limit will be + inf

Answer: 2^6
Step-by-step explanation:
First, when we have:
x^n
this means that we are multiplicating x by itself n times.
Now, in this case we have:
6 factors of 2 would mean that we have:
(2)*(2)*(2)*(2)*(2)*(2)
2 multiplied by itself 6 times.
This is equal to:
