Answer:
So the slope in this case is m = -2. Using point (0, 7) and m =-2 with point-slope we have y - 7 = -2(x-0) => y = -2x +7. Then we realize (0,7) actually is the y-intercept. We could have gone directly to y = -2x + 7. If we use (3,1) and m = -2 we get y-1=-2(x-3) => y -1 = -2x+6 => y = -2x+7. Another way to find y-intercept is to use y = mx +b directly. If we use the point (3,1) that means when x=3, y = 1. So 1=-2(3) + b => 1=-6+b => b = 7. So, y = -2x+7. Same result in all cases. I like to use point-slope. Others prefer to use y = mx+b, substituting for x, y, and m to solve for b.

What's the slop and y intercept of 4y = 2x - 12
Answer:
slope: [tex]\frac{1}{2}[/tex]
y-intercept: (0,-3)
Step-by-step explanation:
First, place the equation in slope-intercept form to identify the slope and y-intercept easily. Isolate the y in the equation to do this:
[tex]4y = 2x-12\\\frac{4}{4} y = \frac{2}{4} x-\frac{12}{4} \\y = \frac{1}{2} x-3[/tex]
Now that the equation is in slope-intercept form, it is much easier to find the slope and y-intercept of the equation. Remember that the slope-intercept formula is [tex]y = mx + b[/tex].
In an equation written in slope-intercept form, the [tex]m[/tex], or the coefficient of the x-term, represents the slope. So, the slope of his equation is [tex]\frac{1}{2}[/tex]. Also, the [tex]b[/tex], or the constant on the right side of the equation, represents the y-intercept. So, the y-intercept of this equation is (0,-3).

PLEASE HELP ME ITS MY LAST QUESTION!!
Write three very large numbers and three very small numbers. Now write them using scientific notation. Then
perform one calculation with the numbers.
100 = 10^2
1000 = 10^3
10000 = 10^4
0.1 = 10^(-1)
0.01 = 10^(-2)
0.001 = 10^(-3)
Now,
100 × 0.1 = 10^2 × 10^(-1)
= 10

When solving equations with square roots it is important to do which of the following?
-make sure the value of x is positive
-check the solution to ensure it is a rational number
-make sure the value of x is an integer
-check the solution to eliminate any extraneous solutions
Answer:make sure the value of x is positive
-check the solution to ensure it is a rational number
Step-by-step explanation: .
When solving equations with square roots it is important,
to make sure the value of x is positive.check the solution to ensure it is a rational numberEquation with square root:When solving equations with square roots it is important to keep in mind;
The value of x must be greater than or equal to zero i.e. value of x should be positive.
Rational number is a number which can be express in p/q form where q can not be equal to zero. Therefore, value of x should be rational number.
If radical expression is present, isolate the radical on one side of the equation. Square both sides of the equation. Solve the new equation.

Are the following figures Congruent, and similar? I need help please.
Answer:
1. possibly congruent
2. possibly congruent
3. congruent
4. similar
Step-by-step explanation:
It is impossible to tell for the first two. In order to be congruent they must have the measurements (lengthes& angles) for all coordinating sides and angles. Since we don't have that info we can only guess and since the look exactly the same we can guess they are congruent.
The third one being on the graph we can tell these are congruent.
the fourth one is obviously not congruent because the side lengths are different. We are guesing that the coordinating angles are congruent
the question did not give enough information to properly answer the questions with confidence

What is the slope of the line below?
A. 1/2
B. 5
C. -1.5
D. -5/2
Answer:
A 1/2
Step-by-step explanation:
(2, -1.5) & (4, -0.5)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-0.5 - (-1.5)) / (4 - 2)
Simplify the parentheses.
= (-0.5 + 1.5) / (2)
= 1 / 2
Simplify the fraction.
1/2
This is your slope.

Brad says 24 ÷ 3 is the same as 3 ÷ 24 because the commutative property works for multiplication, and multiplication and division are related. Cheryl says the order does matter, so 24 ÷ 3 is not the same as 3 ÷ 24. Who do you agree with? Justify your reasoning.
Answer:
I agree with Cheryl.
24 ÷ 3 = 8
3 ÷ 24 = [tex]\frac{1}{8}[/tex]
Commutative property works for multiplication because when you multiply two numbers, you have repeated addition. No matter which way you add up the numbers, you will get the same result. When you divide, you are breaking up a certain number by a certain number. If they are not the same number, you will get a different result.

The volume of a rectangular prism is 360 cubic feet. If the area of the base is 12 square feet, how tall is the prism
Answer:
30ft
Step-by-step explanation:
Given data
Volume= 360 ft^3
Area= 12 ft^2
We know that the expression for volume is
Volume= Area*Height
Substitute
360= 12*h
h= 360/12
h= 30 ft
Hence the height of the prism is 30ft

Answer: 18 quarts for Part a
9 gallons for part b
Step-by-step explanation:
Answer:
Part A: 18
Part B: 4 1/2
Step-by-step explanation:
Part A:
He needs to triple his recipe by 3, so 12 x 3. So you get 36. The question was how many quarts does he need. So 36 divided by 2 is 18. So 18 quarts is needed!
Part B: We need to find out how many gallons he needs, we already know that he has 18 quart. There are 4 quarts in a gallon. So 18 divided by 4 is 4 1/2.

In ANOP, n = 92 inches, o = 60 inches and _P=166º. Find the area of ANOP, to the
nearest square inch.
Answer:
152
Step-by-step explanation:
Charley's grade in the three quarters are 85, 88, and 92. If she targets to have an average
grade of greater than 90 in the four quarters this school year, what is the least grade she
should have for the fourth quarter?
Step-by-step explanation:
We can set up an average equation in the form, where x is the last score in the fourth quarter:
[tex]\frac{85 + 88 + 92 + x}{4} = 90[/tex]
[tex]85 + 88+92 + x =360\\\\x = 95[/tex]
She needs at least a 95 on the last quarter to average 90 in all four quarters.

The diameter of a volleyball is 15.5 find its radius and volume
Step-by-step explanation:
diameter = 2 × radius.
15.5 = 2 × r.
r = 15.5 ÷ 2.
r = 7.75.
volume = πr²
v = π × 7.75².
v = 188.7.
I ain't confident about the volume answer but, the diameter answer is correct.
