Step-by-step explanation:
Given the slope and y-intercept of the line, write the equation in slope-intercept form.
URGENT WILL GIVE BRAINLIEST!!
Answer:
[tex]y=3x-5\\y=\frac{5}{6} x\\y=-4x+1[/tex]
Step-by-step explanation:
Slope intercept form:
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
With those already given, you need only plug them in to the formula:
[tex]y=3x-5\\y=\frac{5}{6} x+0\\y=-4x+1[/tex]
Answer:
3: y = 3x - 5 4: y = 5/6x 5: -4x + 1
Step-by-step explanation:
I just use y = mx + b
x and y are the coordinates and m is the slope of the line (you could find the slope of a line by using rise over run or (y2 - y1) over (x2 - x1)) The y-intercept or b is the point where the line hits the y axis.
Hope this helps a lot!!!
Question 10(Multiple Choice Worth 1 points)
(04.01 LC)
Marneshia walked three over eight of a mile in three over five of an hour. What equation can be used to calculate her unit rate in miles per hour?
a three eighths over three fifths = five eighths mile per hour
b three eighths over three fifths = one and three fifths miles per hour
c three fifths over three eights = one and three fifths miles per hour
d three fifths over three eights = five eighths mile per hour
Answer:
The Answer is A
Step-by-step explanation:
First you take 3/8 and 3/5. After that, you put 3/8 over 3/5. To get Miles per Hour, you want to put distance over time. Next you invert and multiply. When you are doing this you want to have it looking like this: [tex]\frac{3}{8}[/tex] * [tex]\frac{5}{3}[/tex]. Finally you multiply the top and the bottom and reduce the fraction. Your final answer will me 5/8.
What is the equation of the line that passes through (0, 3) and is perpendicular to y = = x + 5?
5
D
when you're doing a perpendicular line, you want the exact opposite of your original.
take, for example, a line with a slope of 2. the line perpendicular to it would have a slope of -2.
With a fraction, its pretty tricky. Let's say you have 2/7 as your slope. you want the EXACT opposite so
First, make it negative
Next, flip it around.
You get -7/2 as your slope perpendicular to your original line.
For the point passing through, if x equals 0, y equals your y intercept. your y value is 3 therefore b (y-intercept) equals 3.
For questions that are less simple than a plain y-intercept, (which you are guaranteed to encounter in the future) you simply input the y and x values into your y=mx+b equation.
Say we have an example here of a line with a slope of 4, and it passes through (5,-3). We have to find our B, or y-intercept, so we input the values.
-3=4(5)+b
Now, simplify
-3=20+b
-23=b
Your example equation is now y=4x-23

Mrs. James displayed the factor tree at the right complete the factor tree to find the number that has prime factorization of 2 to the 4th powerx3
Answer:
48
Step-by-step explanation:
2^4x3=48
2x6=6
(2x2) x (2x6)= 48
The prime factorisation is for the number is48.
What is prime factorisation?Prime factorisation is a method to find the prime factors of a given number, say a composite number. These factors are nothing but the prime numbers. A prime number is a number which has only two factors, i.e. 1 and the number itself. For example, 2 is a prime number which has two factors, 2 × 1.
Given here, 2⁴×3 =48

Assignment: Give a detailed response to this prompt. Write MORE THAN 5 sentences. Make sure you are addressing the prompt and stay on topic.PROMPT:Your friend, Susannah, manages a sandwich shop. She collects data on the number of turkey sandwiches sold per day for a week. Explain to her how to find the mean, median, mode, and range of the number of turkey sandwiches sold. How that would be helpful when she orders new turkey sandwich makings? Which measure do you think would be the most helpful for her and why?
Answer:
In order to find the mean of the sandwich shop you would add all of them up so 73+88+85+88+99+134+129 = 696. Then you divide it by how many days there are which there are 7 days so 696÷7=99.43. To find the median order the number least to greatest, then u count how many numbers are in the set. Count inwards and the median would be 88. The mode is the set of number that is in the problem the most, so in this case the mode would be 88. In order to find the range you subtract the highest number from the lowest number, so 134-73. The range would be 61. The measure that would be most helpful is the median, because it is not affected by the outliers!!

Stan's cookie recipe makes 24 cookies and calls for exactly 384 sprinkles. He is wondering how many sprinkles (p)eft parenthesis, p, right parenthesis he will need to make 60 cookies. He assumes each cookie will have the same number of sprinkles.
How many sprinkles does Stan need to make 60 cookies?
Answer:
960 sprinkles
Step-by-step explanation:
x = sprinkles
For this problem we will create a ratio
[tex]\frac{24}{384} :\frac{60}{x}[/tex]
24x=384*60
24x=23,040
x=23,040/24

Wesley does this work to find the decimal equivalent of 2399. What does his work tell you about the decimal equivalent?
answer is 2399
so yeah mhm yeah u d u m b
Answer:
It is 0.23 with the 23 repeating. The decimal repeats when he divided into the same number twice.
Step-by-step explanation:
23÷99=0.232323232
Since 0.232323232 is a repeating decimal with the 23 repeating, it can be represented as 0.23 with the line over 23

Sorry for the extra words it doesn't allow me to write the vinculum (the line that indicates a number is repeating)
Sam has $372 and Mark has $12.26. What is the difference? Who has more?
Make a plan-how will you solve the problem?
Show your work
Answer:
359.74
sam has more
Step-by-step explanation:
372 - 12.26 = 359.74
372 > 12.26
Answer:
372 - 12.26 = 359.84
372 > 12.26
The difference is 349.84, and I know this because I substracted 12.26 from 372. I know that Sam has more money because 12.26 is less than 372

Step-by-step explanation:
The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).
Answer:
Step-by-step explanation:
If we choose to eliminate x, multiply the first equation by -3: -15x - 6y = 3
and multiply the second by 5: -15x - 35y = 55
Note that this allows us to eliminate x. We get:
-6y = 3
-35y = 55
which sum up to -41y = 58. Thus, y = -58/4.

Answer:
300 + r = 217
Step-by-step explanation:
300 -> 300
added to r -> +
is the same as -> =
217 -> 217
Put this in one equation and you get:
300 + r = 217
If you need to solve for r (need to isolate r to solve for r):
300 + r = 217
r = 217 / (-300)
r = -0.723333333
