Answer:
250-5x=y. is the answer
250 is the y intercept
5 is the slope
Identify the slope and y-intercept of the line. Then write the equation in slope form.
Answer:
The slope is -4, and the y-intercept is 1. The equation is y=-4x+1.
Step-by-step explanation:
To find slope use this equation:
(y2-y1)/(x2-x1)= slope (m)
And the y-intercept is b and you can find that just by looking at the graph.
What is the slope and y-intercept in the following equation? 15x - 3y = 21
Answer:
Slope: 5
Y-Intercept: -7
10x+28−3x=7x+38 Does this equation have one solution, infinitely many solutions, or no solutions? Explain your answer.
Answer:
No solution
Step-by-step explanation:
First we have to solve the equation;
10x + 28 - 3x = 7x + 38
Collect like terms;
7x + 28 = 7x + 38
Subtract 7x from both sides;
28 ≠ 38
No solution, because the number does not equal each other.

Answer:<
Step-by-step explanation:the square root of 11 is 3.3 and that is less than 4
Answer:
<
Step-by-step explanation:
We can solve this easily by simply converting 4 to the root of its square. 4 squared is 16, and root 16 gives back 4 so the value remains the same.
[tex]4 = \sqrt{16 } \\ [/tex]
Now, we can compare the two values. As 11<16, the same will hold true for its square roots.
So your final answer would be <.
Hope this helps! :D

Bill has
WIN
of his pizza left from lunch. If he eats
7
more of the pizza, how much pizza is left pls answer I need help
Answer:
Option D) 5/21 pizza is left.
Step-by-step explanation:
Bill has 2/3 of his pizza left from lunch. If he eats 3/7 more of pizza then we have calculate the pizza left.
Let the size of a pizza is x. Now 2x/3 pizza is left with Bill after lunch.
Therefore pizza eaten by Bill = x - 2x/3 = x/3
Now Bill eats 3/7 more of pizza has been eaten by Bill.Therefore total pizza left is
x - x/3 - 3x/7 = x(1 - 1/3 - 3/7) = x( 21 - 7 - 9)/21 = 5x/21
So 5/21 part of pizza is left.

Kevin was accepted to college and is making plans for next year's budget. He anticipates getting a part-time job and making about $80 a week. In addition, his federal grants will be about $3,000 per semester. What is his income expected to be during the 36-week school year?
Answer:
Kevin's income is expected to be:
$8,880.
Step-by-step explanation:
Income from part-time job = $80 a week
For 36 weeks, he will earn $2,880 ($80 * 36)
Federal grants = $3,000 per semester
For semesters = $6,000 ($3,000 * 2)
Total income = income from part-time job plus the Federal grants
= $8,880 ($2,880 + $6,000)
The implication is that Kevin cannot spend above $8,880 towards his college education, unless he has another source of support during the year. Otherwise, he may resort to borrowing, via college loans.

The average of Landry’s test scores must be at least 92 for her to make an A in Algebra class. She got a 95 on her first test. What grade can Landry get on her second test to make an A in the class?
Average is determined by the sum of test scores divided by total number of tests. This can be represented in this equation:
95 + X / 2 = 92 ⇒ Multiply both sides by 2 to get of the divided by 2
95 + X /2 (2) = 92 (2)
95 + X = 184 ⇒ Subtract 95 from both sides to isolate x
95 -95 + X = 184 -95
X = 89
Therefore, they must get at least 89% to maintain an A.

Step-by-step explanation:
correct on edge 2020.
Answer:
Find the midpoint of the segments which connect their houses.
Step-by-step explanation:
If you find the midpoint between all of their houses, then that midpoint represents where they will meet up. And that is indeed what you are trying to find, you are trying to find.. the midpoint.

When simplifying 5(−2)(9) − 3, a student first subtracted 3 from 9. Is this the correct first step? Explain.
Answer:
No, you should multiply first.
Step-by-step explanation:
Use PEMDAS. It means parenthesis, exponents, multiplication and division (left to right), and addition and subtraction (left to right). You should multiply 5*-2, then that product *9, then subtract 3. Hope this helps! :)

-1/2 divided by what = -7/3
3/14
yan na yung answer sana maka tulong
Answer:
(3/14)
Step-by-step explanation:
(-1/2)/x = (-7/3)
(-1/2) = (-7/3)x
(-3/6) = (-14/6)x
(-3/6) = (-14/6)(3/14)
(-3/6) = (-42/84)
(-1/2) = (-1/2)
(-1/2)/x = (-7/3)
(-1/2)/(3/14) = (-7/3)
(-1/2) x (14/3) = (-7/3)
(-14/6) = (-7/3)
(-7/3) = (-7/3)
y= -2/5X - 2
slope=
y-intercept=
9514 1404 393
Answer:
slope = -2/5y-intercept = -2Step-by-step explanation:
Compare your equation ...
y = (-2/5)x +(-2)
to the slope-intercept form ...
y = mx + b . . . . where m is the slope and b is the y-intercept.
Matching these patterns, you should be able to see that ...
m = -2/5 = slope
b = -2 = y-intercept

A family is saving up for a house payment. If they deposit $400 each month into an account that pays 4.8%intrest compounded monthly how much money will they have in 8 years from now
Answer:
44,956
Step-by-step explanation:
Future value
A family is saving up for a house payment. If they deposit $400 each month into an account that pays 4.8% interest compounded monthly how much money will they have in 8 years from now
The formula =
P = d( (1 + r/k)^nk - 1)/r/k
d = Amount deposited monthly = $400
r = interest rate = 4.8% = 0.048
k = compounding frequency = 12 months
n = number of years = 8
P = 400((1 + 0.048/12)^8 × 12 - 1)/0.048/12
P = (400 ( 1 + 0.004)^96 - 1)/0.004
P = (400 ( 1.4495569791 - 1)/0.004
P = 40(0.4495569791)/0.004
P = 179.82279162/0.004
P = 44955.697906
Approximately
P = 44,956
On a farm, a cow eats about 24 pounds of hay per day. If hay costs $1.55 per pound, how much does it cost to feed a cow each day?
Answer:
$37.20 per day
Step-by-step explanation:
Since $1.55 is the amount per pound you would multiply 1.55 x 24 to get 37.5 and since it is money you would add a zero at the end, it would look like so,
$37.20
Hope that helps and have a great day!
Answer:37.2
Step-by-step explanation:
so first you do 24 since its the pounds and since that's for a whole day so if you do a 24 times 1.55 which is 37.2 i hope this helps and can i get the brainiest
somebody help me :(
Use the following information to complete parts I, II and III.
1 hour = 3,600 seconds
1 year = 31,556,952 seconds
Part I: Use scientific notation to estimate the number of hours in one year.
Part II: Use scientific notation to calculate the exact number of hours in one year.
Part III: In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences in your answers.
Answer:
Part I: Use scientific notation to estimate the number of hours in one year
Using the conversion factors
Estimate using scientific notation
31,556,952 seconds = 3.2 * 10^7
3600 seconds = 3.6 * 10 ^2
1 year = 3.2 * 10^7 seconds * 1 hour/ 3.6 * 10 ^2 seconds
3.2 /3.6 =.88888 (repeating)
10^7 / 10^2 = 10^5
8.88888 * 10 ^5
8.888 * 10 ^4 hours
Part II: Use scientific notation to calculate the exact number of hours in one year.
31,556,952 seconds = 3.1556952 * 10^7
3600 seconds = 3.6 * 10 ^2
1 year = 3.1556952 * 10^7 seconds * 1 hour/ 3.6 * 10 ^2 seconds
3.1556952 /3.6 =.876582
10^7 / 10^2 = 10^5
.876582 * 10 ^5
8.76582*10^4 hours
Part III: In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences in your answers.
Part II is an exact answer, where Part I is an estimate. Both Parts give values in the thousands of hours, and are both between 8700 and 8900 hours. Part I can be done without a calculator where Part II is much harder to do without a calculator.
