Answer:
a) 37 + 42 =79
=7/100 x 79
=553/100
=5.53
Isaac's total bill = 79 + 5.53 = $84.53
b) 25/100 x 79
= 19.75
= 79 - 19.75
= $59.25 (before tax)
7/100 x 59.25
= 414.75/100
= 4.15
= 59.25 + 4.15
= $63.4 (after adding tax)
First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.
Which of the following functions have y-axis symmetry?
a y=x^2,y= |x|, y= cos(x)
b y=sinx, y = cos x, y = x, y = x^3
c. y=x, y=x^3, y=1/x, y=cos x
d. y=1/x, y=sin x, y=x^2
The plot of a function f(x) is symmetric across the y-axis if it is even, meaning f(-x) = f(x) for all x in the function's domain.
The answer is then A because
(-x)² = (-1)² x² = x²
|-x| = |-1| |x| = |x|
cos(-x) = cos(x)
The answer is not
• B because sin(-x) = -sin(x) and (-x)³ = (-1)³ x³ = -x³
• C because -x ≠ x and again because of x³
• D because 1/(-x) = -1/x and again because of sin(x)

What is the equation, in slope-intercept form, of the
perpendicular bisector of the given line segment?
Answer:
x1 = -1, and y1 = -2
Step-by-step explanation:
Step-by-step explanation: The equation of a line in point-slope form. is the equation of the line containing point (x1, y1) and having slope, m. The given point of the perpendicular bisector is (-1, -2), so in this case, x1 = -1, and y1 = -2

A prism with a base area of 3 m2 and a height of 4 m is dilated by a factor of 3/2
What is the volume of the dilated prism?
Enter your answer, as a
decimal, in the box.
х
Answer:
The value of the new volume 'x' would be equal to 40.5 cm³.
Step-by-step explanation:
Given
base area = 3 m²height = 4mDilation by a factor scale of 3/2.We can determine the volume of the original prism by multiplying the area of the base by the height,
volume = (3 cm²)(4 cm) = 12 cm³
Dilation by a factor of 3/2 means that the dimensions of the new prism is 3/2 times that of the original object.
let 'x' be the volume of the new solid,
[tex]\frac{x}{12}=\left(\frac{3}{2}\right)^3[/tex]
[tex]\frac{x}{12}=\frac{27}{8}[/tex]
Multiply both sides by 12
[tex]\frac{12x}{12}=\frac{27\cdot \:12}{8}[/tex]
[tex]x=\frac{81}{2}[/tex]
[tex]x=40.5[/tex] cm³
Therefore, the value of the new volume 'x' would be equal to 40.5 cm³.

a bus is full of passengers. if you count them by either twos, threes, or fives, there is one left. if you count them by seven there will be none left. find the least number of passengers in the bus?
Answer:
91.
Step-by-step explanation:
The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.
2*3*5 = 30 but 31 is not a multiple of 7.
2*2*3*5 = 60 but 61 is not divisible by 7.
2*3*3*5 = 90 and 91 is divisible by 7.

Which equation could be used to find n, the total number of bagels the bakery has?
18 × 30 + 20 × 15 = n
18 + 30 + 20 + 15 = n
18×30−20×15=n
18 + 30 × 20 + 15 = n

Possible rational zeros are of the form ...

1. Rational zeros will be one of ±{1, 2, 3, 6, 9, 18}/{1, 2}, so will be ...
{±1/2, ±1, ±3/2, ±2, ±3, ±9/2, ±6, ±9, ±18}

2. Rational zeros will be one of {±1, ±2, ±3, ±4, ±6, ±8, ±12 ±24}.

3. The pairs of coefficients suggest factoring by pairs:
f(x) = (2x^3 +2x^2) -(8x +8) = 2x^2(x +1) -8(x +1) = 2(x^2 -4)(x +1)
f(x) = 2(x -2)(x +2)(x +1)
Zeros of f(x) are 2, -2, -1, values of x that make the factors zero.
__
4. The sum of coefficients is zero, so x=1 is a zero. Factoring that out by any of several means, you find ...
f(x) = (x -1)(x^2 +2x -8)
The quadratic is factored by looking for factors of -8 that have a sum of 2. (4 and -2 are those)
f(x) = (x -1)(x +4)(x -2)
Zeros of f(x) are 1, -4, 2.

Tracy found the length of GF. Her work is shown below.
Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A E, B F, and C D. The length of line segment A G is 16, the length of line segment G E is 2 x, and the length of line segment B G is 8 x.
16 = 2(2x)
16 = 4x; x = 4
8(4) = 32
GF = 2(32)
GF = 64
What error did Tracy make?
She used AG = 2EG, but the correct statement is 2AG = GE.
She found that x = 4, but the correct value for x is 2.
She used GF = 2BG, but the correct statement is BG = 2GF.
She found that GF = 64, but the correct value of GF is 8.
Answer:
C: She used GF=2BG, but the correct statement is BG=2GF

Step-by-step explanation:
In order to solve two inequalities, we have to graph the two inequalities on the graph. We have used the online graphing calculator "Desmos' for this purpose.
When two inequalities are graphed, the area that is common in both inequalities is the solution of the system.
We have to observe the graph to check if given points are in solution set of the system.
In the given points, (2,4) lie in the solution set as indicated in the picture.
