Answer:
The first, third, andd sixth choice is correct.
Step-by-step explanation:
The y-intercept is when x = 0.
So if we plug x = 0 into the equation.
y = -4(0) + 98
y = 98
So the first choice is correct.
y = mx + b
y = -4x + 98
m = slope
b = y-intercept
So, the slope must mean it's decreasing.
So the third choice is correct.
Let try plugging in values for x.
y= -4(0) + 98 = 98
y= -4(1) + 98 = 94
y= -4(2) + 98 = 90
x stands for the number of days the students miss.
We see the bigger the value we put in for x, the lower the test score is aas represented by y.
So, the sixth choice is correct.
we know that,
y intercept exist when x = 0
so,
⇢y = -4x +98
⇢y = -4 x 0 +98
⇢y = 98
so , the expected test score is 98
Based on the linear regression equation, the slope means that for every missed class, the expected tast score decreases by 4 points✓when x = 0
y = -4(0) +98
when x = 1
y= -4(1) +98 = 94
when x = 2
y= -4(2) +98 = 90
we can see the decresement of 4 points
Based on the linear regression equation, as the number of days a student misses class increases the expected test score decreases ✓We can see that the increament in absent days lead to lower scores ( one class = 4 points)

Answer: Will need 7 week of time to afford a car worth 1932
Step-by-step explanation:
Missing information : car is worth 1932
Will works 7 hours day, 6 days a week.
=> Number of hours worked in a week = 7 * 6 = 42 hrs
paid 9.20 an hour
=> will Weekly payment = 42 *9.2 = 386.4
will : mum = 5:2.
=> Will share = (5/7) * 386.4 = 276
car is worth 1932
Number of Weeks taken by will to afford a car = 1932/276 = 7
divide 40 into ratio of 5:2
The ratio of monthly income to the saving of a family is 5:2.

The sum of three consecutive numbers is 18. Find the smallest number :-
Answers
Answer:
The numbers are 5, 6, and 7. The smallest number is 5.Step-by-step explanation:
Given :-The sum of three consecutive numbers is 18.To Find :-The smallest number.Solution :-➊ To find the smallest number, let us consider the three consecutive numbers be x, x + 1, and x + 2.
Given :
Sum of the numbers = 18.Numbers = x, x + 1, and x + 2.According to the question,
↦ x + x + 1 + x + 2 = 18
↦ 3x + 3 = 18
↦ 3x = 18 - 3
↦ 3x = 15
↦ x = 15/3
➦ x = 5
∴ Hence, the required value of x is 5.
➋ Now we have the value of x. So, by putting the value of x in the assumed numbers we will find out the numbers and then check which is the smallest number.
➲ First number = x = 5.
➲ Second number = x + 1 = 5 + 1 = 6.
➲ Third number = x + 2 = 5 + 2 = 7.
∴ Hence, the smallest number is 5.
✻ Verification ✻
↦ x + x + 1 + x + 2 = 18
Putting x = 5 we get,
↦ 5 + 5 + 1 + 5 + 2 = 18
↦ 5 + 6 + 7 = 18
↦ 18 = 18
➦ LHS = RHS
∴ Hence, Verified ✔

Hope that helps!
I think the question should be as follow:
➙ 6x + 9 - ( 5x - 3 )
➙ 6x + 9 - 5 x + 3
➙ 6x - 5x + 9 + 3
➙ x + 12
➙ x = -12
Anyways I've also solved according to the provided question:
ㅤㅤㅤ➙ 6x + 9 (-5x - 3 )
ㅤㅤㅤ➙ 6x - 45x - 27
ㅤㅤㅤ➙ - 39 x - 27
Further, we can solve for x ;
ㅤㅤㅤ➙ - 39 x - 27 = 0
ㅤㅤㅤ➙ - 39 x = 0 + 27
ㅤㅤㅤ➙ x = - 27 / 39

Dennis has two paying jobs. One at target that pays $18 per hour and one at the Hartford insurance co. That pays $24 per hour. He needs to make at least $288 each week. Between the two jobs he can work more than 24 hours per week
Answers
Answer:
You can also divide the standard hourly rate by 2 and then add this amount to their standard rate. For example, if the hourly rate is $10, then divide $10 by 2 to produce $5. When you add that $5 to the $10 rate, this overtime rate equals $15. As another example, if someone makes $20 per hour, then the overtime rate is $30 ($20 x 1.5 = $30).

Answers
Answer:
Marcy is correct
Step-by-step explanation:
If you had 3 straws that were the SAME length then there would only be 1 possible way to arrange them because no matter what order you put them in to form a triangle the outcome would always be the same because all 3 straws are the same length.
Since there are different lengths of straws, there are 3 possible ways you can arrange them so basically, there are multiple ways you can arrange the straws to make a triangle.
Marcy is correct.
Ryan is wrong.
