Sam figures that he also earns about $2.50 in tips for each person he serves.
Sam works 4 hours on a particular day.
If n represents the number of people Sam serves that day, which of the
following functions could Sam use to figure E, his total earnings for the day?
An+ 10
Answers
Option c is the correct answer. Sam's total earning for the day is equal to
E(n) = 2.5n + 24
Given data
Sam earning per hour = $6
Sam earning on tips per person = $2.5
Sam's total hour per day =4
How to find the function for Sam's total earningsSam's daily earning excluding tips = Sam earning per hour * Sam's total hour per day
= $6 * 4 hours = $24
If n represents the number of people Sam serves that day, then Sam's earnings on tips in a day = $2.5 * n = $2.5n
The function for Sam's total earning is given by E(n)
E(n) = Sam's daily earning excluding tips + Sam's earnings on tips in a day
E(n) = $24 + $2.5n
this is re arranged as
E(n) = 2.5n + 24
Therefore we can say that Sam's total earning for the day is equal to

What equation/inequality represents the following scenario? Product of two consecutive odd integers is less than 76, where b is the first odd integer
a) n(n+2)> with a line under 76
b) n(n+1)>76
c) n(n+1)<76
d) n(n+2)<76
Answers
The two consecutive odd integers are less than 76 is the numbers are 37 and 39.
Any integer's reverse and sum are both equal to zero.
A positive sum results from adding two positive numbers, whereas a negative sum results from adding two negative integers.
Take the absolute value of each integer, then subtraction, to obtain the total of a positive and a negative integer.
Let two consecutive odd numbers be x and x+2
According to question
⇒ x........... equation (1)
⇒ x+2........equation (2)
by adding equation 1 and 2
⇒ x+x+2=76
⇒ 2x+2=76
⇒ 2x=76-2
⇒ 2x=74
⇒ x=74/2
⇒ x=37
We apply the value of x=37 in equation (2)
⇒ x+2
⇒ 37+2
⇒ 39
so, the numbers are 37 and 39.
Therefore, the two consecutive odd integers are less than 76 is the numbers are 37 and 39

What is referred as the inequalities?An inequality depicts the relationship between two non-equal values in such an algebraic expression. Inequality symbols can indicate that one of the two variables is greater than, greater or equal to, equal to some other value.For the given question;
The area of rectangle A is bigger than the area of rectangle B.
The sides of the rectangle A are 2x-3 and 5 cm.
Area = length×breadth
Area A = (2x - 3)(5)
Area A = 10x - 15
The sides of the rectangle B are x = 2 and 3 cm.
Area = length×breadth
Area B = (x + 2)3
Area B = 3x + 6
As area B > area B
Then,

Step-by-step explanation:
-3y + 2x = -7
8x - 3y = -1
make one of the equations y=....
-3y + 2x = -7
-3y = -7 - 2x
y = (-7 - 2x)/3
now put (-7 - 2x)/3 where y is in the other equation
8x - 3y = -1
8x - 3((-7 - 2x)/3) = -1
8x - 1*(-7 - 2x) = -1
8x + 7 + 2x = -1
solve for x
8x + 7 + 2x = -1
8x+2x = -8
10x = -8
x = -8/10
x = -4/5
now put -8/10 in one of the equations to get what y is
-3y + 2x = -7
-3y + 2(-8/10) = -7
-3y - 16/10 = -7
-3y = -7 + 16/10
-3y = -70/10 + 16/10
-3y = -54/10
y = -54/10 * -1/3

Intervals where the function is positive and intervals where it is negative
Answers
The positive interval is (0,2) and the negative range is calculated as (-4,0) and (2,4).
A graph is used to show the relationship between variables on a coordinate plane.
The domain of the function is [-4,4].
The zeros are: -2,0 and 2.
The positive interval is between (0,2).
The range of negative values is (-4,0) to (2,4). This is the set of x values in the graph. The graph demonstrates that the x value is between -4 and 4.
Thus, the domain is [-4,4]. The zeros of the function: Where it crosses the x- axis. The graph touches the x-axis when it is at -2,0 and 2. As a result, the function has the following zeros:-2,0 and 2.
Positive interval:
On the graph, positive values range from x = 0 to x = 2.
Consequently, the positive interval is (0,2).
Negative duration:
This is the x values when the function gives a negative result.
The graph shows negative values from x = -4 to x = 0, then from x = 2 to x = 4.
The negative range is therefore (-4,0) and (2,4).
Hence, the positive interval is (0,2) and the negative range is (-4,0) and (2,4).

Write an equation of each line.slope =0 ; through (4,-2)
Answers
The equation of the line, with slope equal to 0 and passing through the point located at (4 , -2), is y = -2.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the point slope form, plug in the values to set up the equation.
(y - y1) = m(x - x1)
where m = 0 and (x1 , y1) = (4 , -2)
(y - -2) = 0(x - 4)
(y + 2) = 0
y = -2

Answers
The measures of the sides of ΔXYZ are XY = 9.1, YZ = 11.4, XZ = 8. and the triangle XYZ must be an acute triangle
In this questions we have been given the the coordinates of the triangle XYZ.
X(-4, -2), Y(-3, 7), Z(4, -2)
We need to find the measures of the sides of ΔXYZ .
We find the the measures of the sides using distance formula.
XY = √[(7 + 2)² + (-3 + 4)²]
XY = √[9² + 1²]
XY = √(81 + 1)
XY = √(82)
XY = 9.1
Now side YZ
YZ = √[(-2 - 7)² + (4 + 3)²]
YZ = √[(-9)² + (7)²]
YZ = √81 + 49
YZ = √130
YZ = 11.4
And the length of side XZ would be,
XZ = √[(-2 + 2)² + (4 + 4)²]
XZ = √0 + 8²
XZ = 8
We find the sum of the squares of the two smaller sides, and compare the sum to the square of the largest side.
the sum of the squares of the two smaller sides is,
= 8² + 9.1²
= 64 + 82.81
= 146.81
= 12.12²
And 11.4² = 129.96
Since the sum of the squares of the two smaller sides is greater than the square of the largest side, the triangle must be an acute triangle.
Therefore, the measures of the sides of ΔXYZ are XY = 9.1, YZ = 11.4, XZ = 8. and the triangle XYZ must be an acute triangle

a. A circle contains the points (0,0),(6,8) , and (7,7) . Find its equation by solving a system of three equations.
Answers
Using system of three equations, the equation of the circle that contains the points (0 , 0), (6 , 8), and (7 , 7) is (x - 3)^2 + (y - 4)^2 = 25.
The standard form of the equation of circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Substituting the values of the x and y coordinates of each point to the standard form of the equation of a circle, the three system of equations are:
(x - h)^2 + (y - k)^2 = r^2
(0 , 0) : (0 - h)^2 + (0 - k)^2 = r^2
(6 , 8) : (6 - h)^2 + (8 - k)^2 = r^2
(7 , 7) : (7 - h)^2 + (7 - k)^2 = r^2
Expanding these equations,
(0 , 0) : h^2 + k^2 = r^2 (equation 1)
(6 , 8) : 36 - 12h + h^2 + 64 - 16k + k^2 = r^2 (equation 2)
(7 , 7) : 49 - 14h + h^2 + 49 - 14k + k^2 = r^2 (equation 3)
Subtracting equation 1 from equation 2 and 3.
36 - 12h + h^2 + 64 - 16k + k^2 = r^2
- (h^2 + k^2 = r^2)
36 - 12h + 64 - 16k = 0
100 - 12h - 16k = 0
12h + 16k = 100
Dividing both sides by 4,
3h + 4k = 25 (equation 4)
49 - 14h + h^2 + 49 - 14k + k^2 = r^2
- (h^2 + k^2 = r^2)
49 - 14h + 49 - 14k = 0
98 - 14h - 14k = 0
14h - 14k = 98
h + k = 4 (equation 5)
h = 7 - k
Substitute h = 7 - k to equation 4 and solve for k.
3h + 4k = 25 (equation 4)
3(7 - k) + 4k = 25
21 - 3k + 4k = 25
k = 25 - 21
k = 4
Substitute the value of k to equation 5 and solve for h.
h = 7 - k (equation 5)
h = 7 - 4
h = 3
Substitute the value of h and k to equation 1 and solve for r.
h^2 + k^2 = r^2 (equation 1)
3^2 + 4^2 = r^2
9 + 16 = r^2
r^2 = 25
r = 5
Hence, the equation of the circle that contains the points (0 , 0), (6 , 8), and (7 , 7) is (x - 3)^2 + (y - 4)^2 = 25.
