Answer:
6and8
Step-by-step explanation:
I took the quiz you know yeah
A student said that x = 4 was not a solution to the question 3(x -6) = -8
Here is their work:
3(x -6) = -8
3 (4 -6) = -8
12 -6 = -8
6≠ -8
so x = 4 is not a solution
Did the student substitute x=4 correctly? How do you know?
Did the student simplify with Order of Operations correctly? How do you know?
If you try the problem, what do you get when you substitute x=4 into the equation?
Answer:
Step-by-step explanation:
3 (4 -6) = -8 is correct. The next step is to combine 4 and -6, obtaining
3(-2)
and this 3(-2) should equal -6, which is not the same as -8.
3(4 - 6) = 12 - 18, which differs from the student's solution. This is the reason for the wrong answer.

The domain of a quadratic is all real numbers.
a) True
b) False
Answer:
Step-by-step explanation:
I'd be very hesitant to say true.
If the quadratic is in the form of y = x^2 then the statement is correct. The entire family all have a domain of all the real numbers.
However if the quadratic is of the form x=y^2 then the starting point of this quadratic is (0,0). All of these quadratics have a different starting point. \\
Since you have not specified the kind of quadratic, the answer is not always true.

ABC is a right triangle. If AC=4 and BC=10, find AB. Leave your answer is the simplest radical form.
Answer:
√116 or √84Step-by-step explanation:
ABC is a right triangle
AC=4, BC=10, AB = ?Here we have two options:
1. AB is hypotenuse, then:
AB = [tex]\sqrt{AC^2 + BC^2} = \sqrt{4^2 + 10^2} = \sqrt{16 + 100} =\sqrt{116}[/tex]2. BC is hypotenuse and AB is the second leg, then:
AB = [tex]\sqrt{BC^2 - AC^2} = \sqrt{10^2 - 4^2} = \sqrt{100 - 16} = \sqrt{84}[/tex]B.
-2x + 8 = y
3x - y = 22
How do I solve it
answer
x=6, y=-2
explanation
-2x + 8 = y -------equ 1
3x - y = 22 -------equ 2
u can use any of the simultaneous equation method
using elimination method
rearrange first from -------equ 1
-2x+8=y
-y-2x=-8
multiple through by -1
y+2x=8 -------equ 3
rearrange first from -------equ 2
3x-y=22
-y+3=22 ------equ 4
equate 3 and 4, adding them together
y+2x=8 -------equ 3
-y+3=22 ------equ 4
0+5x=30
5x=30
x=6------equ 5
replace 6 for x in any equation
using -------equ 3
y+2x=8
y+2(5)=8
y+10=8
y=8-10
y=-2
Answer:
(x, y)=(6, -4)
Step-by-step explanation:
-2x+8=y
3x-y=22
Substitute the given value of y into the equation 3x-y=22
3x-(-2x=8)=22
Solve the equation for x
x=6
Substitute the given value of x into the equation 3x-y=22
3x6-y=22
Solve the equation for y
y=-4
The possible solution of the system is the ordered pair (x, y)
(x, y)=(6, -4)
Check if the given ordered pair is the solution of the system of equations
-2x6+8=-4
3x6-(-4)=22
Simplify the equalities
-4=-4
22=22
Since all of the equalities are true, the ordered pair is the solution of the system
(x, y)=(6, -4)

Find the surface area
of a water tower that is
40 feet tall and 20 feet
across the base.
square feet
Do NOT round your answer.
Answer:
the surface area is 3140 square feet
Step-by-step explanation:
The computation of the surface area is given below:
Given that
Diameter = 20 feet
radius = 20 ÷ 2 = 10 feet
Surface area = [tex]2\pi r^2 + 2\pi rh[/tex]
= 2 × 3.14 × (10)^2 + 2 × 3.14 × 10 × 40
= 6.28 × 100 + 6.28 × 400
= 628 + 25.12 × 100
= 628+ 2512
= 3140 square feet
hence, the surface area is 3140 square feet

Part A The ordered pair that represents the intersection of the x-axis and y-axis is called the _ A endpoint B origin C x coordinate D y coordinate. Part B the coordinates of the origin are _ A (1,1) B (0,1) C (0,0) D (1,0) I will give 15 brain
Answer: Part A. B origin Part B. C(0,0)
Step-by-step explanation:
In a coordinate plane, there are two axes
1) x-axis which is the horizontal axis.
2) y-axis which is the vertical axis.
The intersection of both the axes is known as the origin whose coordiantes are (0,0), i.e. at this point value of x =0 and value of y =0.
Part A: The ordered pair that represents the intersection of the x-axis and y-axis is called the origin.
Part B: The coordinate. Part B the coordinates of the origin are (0,0).

Hummingbirds have unusually large hearts for their body size. If a person's heart were as
big as a hummingbird's, his or her heart would weigh as much as a large dog.
Information you will need:
An average hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875
ounces.
1 pound = 16 ounces
The average weight of a large dog is usually more than 80 pounds.
Leo weighs 192 pounds.
a.) How much would Leo's heart weigh if it were the same ratio as a hummingbird's?
Show your work on your paper.
b.) is the original claim true or false? Justify your reasoning here along with your answer.
Answer: 4.8lbs, This claim is false
Step-by-step explanation:
Leo weighs 192 pounds. Then Leo's heart weight will be 76.258 ounces. So, its claim is false.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Hummingbirds have abnormally huge hearts for their body size. In the event that an individual's heart was essentially as large as a hummingbird's, their heart would weigh as much as an enormous canine's. A typical hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875 ounces.
The ratio of heart to weight is given as,
Ratio = 0.00875 / 0.3524
Ratio = 0.024829
The average weight of a large dog is usually more than 80 pounds. Leo weighs 192 pounds. Then Leo's heart weight is calculated as,
⇒ 0.024829 x 192 x 16
⇒ 76.28 ounces
Their heart weight of Leo is less than the weight of the dog. So, its claim is false.
More about the ratio and the proportion link is given below.
