The linear function is represented by the equation y = -3/5x -2. What can be determined of this equation written in slope-intercept form? Check all that apply
Answer:
We can determine the slope m and the y-intercept of the linear function when the linear equation y = -3/5x -2 is written in slope-intercept form.
Thus, we concluded that:
The y-intercept b = -2The slope m = -3/5Step-by-step explanation:
The slope-intercept form of the linear/line function
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven that the linear function is represented by the equation
[tex]y\:=\:-\frac{3}{5}x\:-2[/tex]
comparing with the slope-intercept form of the linear/line equation
[tex]y = mx + b[/tex]
Therefore,
The slope m = -3/5The y-intercept b = -2Hence, we can determine the slope m and the y-intercept of the linear function when the linear equation y = -3/5x -2 is written in slope-intercept form.
Thus, we concluded that:
The y-intercept b = -2The slope m = -3/5

This is 10 questions please answer. 1.Write the ratio as a fraction in the simplest form 15 girls to 6 boys. 2.Write The ratio as a fraction in simplest form 24 players: 3 teams.
3. Write The ratio as a fraction in simplest fraction form 48 worksheets: 12 students.
4. Tell whether the ratios form a proportion 4/7 the 4 is on top of the 7 24/35 the 24 is on top of the 35. 5. Tell whether the ratios form a proportion 11/12 11 top of the 12 33/36 33 on top of the 36. 6. 8/24 8 on top of 24 5/15 5 on top of the 15. 7.3/7 3 is on top of the 7 12/21 12 top of the 21 8. Tell whether the two rates form a proportion 25 cars in 5 days; 60 cars in 12 days.
9.14 books in 2 boxes; 20 books in 3 boxes.
10.On a monday you swim 12 laps in 30 minutes. On tuesday you swim 15 laps in 45 minutes are these rates porportional? Explain.
Answer and explanation:
1. 15 girls to 6 boys = 15:6
15/6= 5/2
2. 24 players to 3 teams = 24:3
24/3= 8/1=8
3. 48 worksheets to 12 students =48:12
48/12= 4/1
4. 4/7 and 24/35 are not proportional as they do not reduce to same ratio
5. 11/12 and 33/36 are proportional because they reduce to same same ratio(33/36=11/12)
6. 8/24 and 5/15 are proportional beacaue they reduce to same ratio(8/24=5/15=1/3)
7. 3/7 and 12/21 are not proportional because they do not reduce to same ratio(3/7≠12/21)
8. 25 cars in 5 days= 25/5= 5 cars each day. 60 cars in 12 days = 60/12=5 cars each day. Therefore they are proportional.
9. 14 books in 2 boxes= 7 books per box. 20 books in 3 boxes = 20/3= 6.667. Therefore they are not proportional.
10. 12 laps in 30 minutes =12/30=2/5
15 laps in 45 minutes =15/45=1/3. Therefore they are not proportional.

A statistics student has a mean score of 92 in the first 3 tests. Suppose there are a total of 4 tests and all of them have equal weight. You can also assume that there is no extra credit in the last test. What is the best possible final average this student can get
Answer:
The best possible final average this student can get is 94.
Step-by-step explanation:
The average score is given by the sum of the scores of all tests divided by the number of tests.
In this question:
First three tests: Mean score of 92, so total score of 92*3 = 276
Best possible score, with 4 tests:
In the first three, the total is 276. The best possible score is with a grade of 100 in the fourth test. The score will be:
[tex]M = \frac{276+100}{4} = \frac{376}{4} = 94[/tex]
The best possible final average this student can get is 94.
If you borrow $1,000 at a 5% interest for six months what amount would you need to pay back if you paid back the principal and interest at the end of the loan?
Answer:
A = $1,025.00
I = A - P = $25.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 1000(1 + (0.05 × 0.5)) = 1025
A = $1,025.00
The total amount accrued, principal plus interest, from simple interest on a principal of $1,000.00 at a rate of 5% per year for 0.5 years (6 months) is $1,025.00.

Convert these mixed numbers into improper fractions.
2 2/3
1 4/7
Answer:
[tex]2\frac{2}{3}[/tex] = [tex]\frac{8}{3}[/tex]
[tex]1\frac{4}{7}[/tex] = [tex]\frac{11}{7}[/tex]
Step-by-step explanation:
[tex]2\frac{2}{3}[/tex]
To convert a mixed number to an improper fraction all you need to do is......
Multiply the denominator of the fraction (3), by the whole number (the big number in front of the fraction) (2), and then you add the numerator....
Denominator times the whole number ( 3 * 2 = 6)
Now add the numerator with what you got ( 6 + 2 = 8)
Now the "8" will be the new numerator, and the denominator stays the same "3".
Improper fraction: [tex]\frac{8}{3}[/tex]
__________________________________________________________
[tex]1\frac{4}{7}[/tex]
We can do the same steps we did for the one above
Multiply the denominator (7) by the whole number (1), and then add the numerator (4)....
Denominator times whole number ( 7 * 1 = 7)
Add the numerator to the answer you got ( 7 + 4 = 11)
Now "11" will be the new numerator, and the denominator stays the same "7".
Improper fraction: [tex]\frac{11}{7}[/tex]
Hope this helped!

If you were to use the substitution method to solve the following system, choose the new
equation after the expression equivalent to x from the second equation is substituted into
the first equation. (5 points)
3x + 2y = -21
x-3y=4
3(3y + 4) + 2y = -21
O 31-3y + 4) + 2y = -21
3x + 2(3y + 4) = -21
3x + 21-3y + 4) = -21
Yes it is yep correct 1000% 10000000000000%
Which is the equation of a line parallel to the line with the equation:
y = 1/4x + 2
answer:
y=1/4x-7
Step-by-step explanation:
equations with the same slope are parallel no matter the y-intercept
Answer:
I don't think it's specified but I can tell you the slop has to stay the same but the y-intercept ha
s to be a different number.
if over a certain point the all you have to do is plug the points into x and y and remove the y intercept. An example is what line is parallel to y=1/4x+2 and crosses point (4,2).
Then you first have to plug in x and y and remove the y intercept to find a new y intercept. 2=1/4(4)+B
Next is to put together common like terms. 2=1+B
Then subtract one because that's it's opposite leaving B=1
then you substitute or replace the old y intercept with the new one making the answer Y=1/4x+1
I hope this will help you.
What is 38 percent of 10 oranges
Answer:
The answer is 3.8
Explanation:
Move the decimal over once to the left.
Answer:
3.8 oranges.
Step-by-step explanation:
Step 1: Our output value is 10.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 10=100%.
Step 4: Similarly, x=38%.
Step 5: This results in a pair of simple equations:
10=100%(1).
x=38%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
10/x= 100%/38%
Step 7: Again, the reciprocal of both sides gives
x/10 = 38/100
---> x=3.8$
Therefore, 38% of 10 is 3.8
