(c) Paul uses the function y = 7x + 30 to model the situation. What score does Paul’s model predict for 3 hours of homework?
(d) Describe what the number 30 in Part (c) mean in the context of the situation?
Answer:
(c) Paul's model predicts a score of 51 for 3 hours
(d) 30 represents the y intercept
Step-by-step explanation:
Given
[tex]y = 7x + 30[/tex]
Solving (c): What is y when x is 3
Substitute 3 for x in [tex]y = 7x + 30[/tex]
[tex]y = 7*3 + 30[/tex]
[tex]y = 21 + 30[/tex]
[tex]y = 51[/tex]
Solving (d): What does 30 represent
An equation is represented as:
[tex]y = mx + b[/tex]
Where
[tex]b = y\ intercept[/tex]
Compare: [tex]y = mx + b[/tex] to [tex]y = 7x + 30[/tex]
[tex]b = 30[/tex]
This implies that 30 represents the y intercept

Answer:
um the answer is 0=0 (no cap)
Step-by-step explanation:
hope this helps!
please mark me as brainliest. Thanks!
Answer:
Step-by-step explanation:
Distributive property: a(b +c) =(a*b) + (a*c)
-6(x - 1/2) = 3x + 3 - 9x
[tex]x*(-6) - \frac{1}{2}*(-6) = 3x - 9x + 3\\\\[/tex]
[tex]-6x + 3 = -6x + 3\\[/tex]

Answer:
[tex] x = 75\degree [/tex]
Step-by-step explanation:
[tex] m\angle EFB +105\degree = 180\degree [/tex]
(linear pair angles)
[tex] m\angle EFB = 180\degree - 105\degree [/tex]
[tex] m\angle EFB = 75\degree [/tex]
[tex] \because x = m\angle EFB [/tex]
(corresponding angles)
[tex] \therefore x = 75\degree [/tex]

The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?
Answer: 45
Step-by-step explanation:
3(-2m + 5) -6(-4m - 2) =
-6m + 15 + 24m + 12=
18m + 27
18= a 27= b 27 + 18= 45
The value of the expression a + b is 45.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we can simplify the expression using the distributive property:
3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12
Combining like terms, we get:
18m + 27
So, a = 18 and b = 27, which means:
a + b = 18 + 27 = 45
Therefore,
The value of a + b is 45.

Which term has the definition "A fraction when the top and bottom cannot be any smaller, while still being whole numbers"? Group of answer choices Numerator Simplest Form Denominator Least Common Multiple (LCM)
Answer:
simplest form
Step-by-step explanation:
Simplest form is a method of converting the fraction to its lowest multiple.
For example, the fraction 25/100 isn't in its simplest form
Both the numerator and the denominator can be divided by 5. When divided by 5 the fraction becomes 5/20.
5/20 is still not in its simplest form because it can be divided by 5. When divided by 5, the fraction becomes 1/4.
1/4 is now in its simplest form because both the numerator and denominator cannot be divided by any other number
A certain college enrolled 29,000. It was reported 54 percent were female and 46 percent were male. In addition 61 percent were over the age of 25. How many students were in each category if 30 percent of those over the age if 25 were male
Answer:
Step-by-step explanation:
Total number of students = 29000
Number of female = 54% of 29000
54/100 x 29000 = 15660 students
Number of male = 46% of 2900
46/100 x 29000= 13340 students
61% of 29000 are over 25 years
61% of 29000= 61/100 x 29000
= 17690 students
Of the pupils over the age of 25, 30% are male
30% of 17690 students are male
30/100 x 7690 =5307 students
The number of females over the age of 25 = 17690 -5307
17690 - 5307 = 12383 female students.
