The residual value when the value of x = 4 is -1, the correct option is B.
Given
Melissa collected the data in the table.
Residual valueThe difference between the observed value of the dependent variable (y) and the predicted value (ŷ) is called the residual.
The value of x= 4 then the value of residual is given by;
[tex]\rm Residual=Given - predicted \ value[/tex]
Here, given is 9 and the predicted value is 10 for x =4.
Substitute all the values in the formula;
[tex]\rm Residual=Given - predicted \ value\\\\\rm Residual=9-10\\\\\rm Residual=-1[/tex]
Hence, the residual value when the value of x = 4 is -1.

Answer:
a) rise 5, run 5, slope 1
b) rise 10, run 5, slope 2
Step-by-step explanation:
The rise is the vertical difference between the points. It is the length of the vertical side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the y-coordinates of the points.
The run is the horizontal difference between the points. It is the length of the horizontal side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the x-coordinates of the points.
a)rise = 5; run = 5. (counting grid squares)
slope = rise/run = 5/5 = 1
__
b)rise = 10; run = 5. (taking coordinate differences: 5-(-5) = 10; 4-(-1) = 5)
slope = rise/run = 10/5 = 2

What would be the total cost of purchasing the number of shirts needed to use your coupon—after your coupon is applied and a 7. 5% sales tax is charged on the purchase?.
The cost of purchasing the number of shirts after discount and sale tax is $40.3125.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
The discount is 25%.
The total price before the coupon is $50.
The sale tax is 7.5%
The cost of purchasing the number of shirts after discount will be
[tex]\rm Cost = 50*(1-0.75 )\\\\Cost = 97.5[/tex]
The cost of purchasing the number of shirts after the sale will be
[tex]\rm Cost = 37.5*(1.075)\\\\Cost = 40.3125[/tex]
The cost of purchasing the number of shirts after discount and sale tax is $40.3125.

Mrs. Thomas car averages 23 miles per gallon. How many gallons of gasoline will she need in order to make the round trip ? If the price of gasoline is $2.13 per gallon, what is the cost of the gasoline for the entire trip?
In addition to paying for the gasoline, Mrs. Thomas must also pay $13.92 fo her lunch and $32.98 for her dinner. What is the total amount of her meal expenses?
a. What is the total amount of her gasoline and meal expenses?
b. What operation did you use to figure it out ?
Answer:
a. $70.43
b. 23.43 + 13.92 + 32.98 = t (UNSURE)
Step-by-step explanation:
Since Mrs. Thomas is driving 231 miles using 23 miles per gallon, let's start by dividing 231 by 23
[tex]\frac{231}{23} = 10.043....[/tex]
We need to round 10.043... to 11 because you can't get part of a gallon.
Now, we need to multiply 2.13 by 11 to get the total amount of money for gasoline.
[tex]11 * 2.13 = 23.43[/tex]$
We also have the aditional meal expenses, which are $13.92 and $32.98.
We can use an equation to solve. Our total amount will be represented by t.
[tex]23.43 + 13.92 + 32.98 = t[/tex]
[tex]t = 70.43[/tex]

What is the equation of the line that passes through the point (3,5) and has a slope of 2?
Answer:
y=2x-1
Step-by-step explanation:
The equation for a line (slope-intercept form) is:
y=mx+b
m: slope
b: y-intercept
x and y: (x, y) coordinate pair
In this scenario, since we are given the slope and a point on the line, we can solve for the y-intercept:
y=2x+b
5=2(3)+b
5=6+b
Subtract 6 from both sides
b=-1
Therefore the equation of the line is:
y=2x-1

In the rectangle below, AC has a length of 28 units. What is the length of DE?
D
A
LD
O A. 56 units
O B. 21 units
O C. 28 units
D. 14 units
Answer:
D. 14 units
Step-by-step explanation:
it is a rectangle.
that means both diagonals are equally long.
E is in the middle of of diagonals.
so, since the whole diagonal (AC = DB) is 28 units long, one half of such a diagonal (AE = EC = DE = EB) is then
28/2 = 14 units long.

Is 690,269 divisible by 9? Yes or No?
False, But I do not know why, I do not know whether it is false or not, but I think it is false.
Answer:
False.
Step-by-step explanation:
It is false because when dividing an odd number by an odd number, it usually isn't divisible. In this case, 690,269. Is an odd number, because the last number, 9, is odd, which makes the whole thing odd. So, odd divided by odd never turns out well. (By the way the answer is 76,696.5555556).

Answer:
f(x)=2x−5 if x≤−3
Since the value of x is -3, the first function will be the correct option.
Step-by-step explanation:
The given function is -
f(x)=2x−5 if x≤−3
f(x)=−3x+4 if x>−3
Now we have to evaluate f(-3).
Since we have to calculate the value of f at x = -3, we have to choose the first function.
That is f(x) = 2x - 5.
Hence,
f(−3)=2∗(−3)−5=−6−5=−11
Therefore we have the value
f(−3)=−11
Since the domain of the function is divided into two parts, we have to choose any one function for a given value of x,
For values of x less than or equal to -3, we will use the first function. That is,
f(x)=2x−5 for all x∈(−∞,−3]
And for values of x greater than -3, we will use the second function. That means,
f(x)=−3x+4 for all x∈(−3,∞)
What would you make the size of one of the sides of a right triangle if its other side is 12cm and the hypotenuse is 20cm?
A triangle has the three sides of 2cm, 6cm, and
[tex] \sqrt[2]{10} cm[/tex]
is it a right triangle-yes or no
Step-by-step explanation:
1. 400-144 = 256
unknown side = 16 cm
2.
√10 = 3.16
the biggest side is hypotenuse. assuming 6cm is the hypotenuse.
4+10= 14, which is different From hypotenuse. so it's not a triangle
