How do you answer this? (this is for slopes.)
Answer:
[tex]y= 2x + 4[/tex]
Step-by-step explanation:
We are given an equation of [tex]2x-y+3 =-1[/tex] and we need to put into [tex]y = mx+b[/tex] form.
First, we subtract 3 on both sides to get the variables all on one side.
[tex]2x-y+(3 - 3)=(-1 -3)\\\\[/tex]
[tex]2x-y = -4[/tex]
We need to now isolate y on its own so we subtract [tex]2x[/tex] on both sides.
[tex](2x-2x)-y=(-4-2x)[/tex]
[tex]-y=-2x-4[/tex]
We almost done! We then need to divide the invisible negative on both sides which is a -1.
[tex]\frac{-y}{-1}=\frac{-2x-4}{-1}[/tex]
[tex]y=2x+4[/tex]
When we divide the the negatives together, we know that two negatives divided together is a positive. Therefore, we get our answer [tex]y=2x+4[/tex]

Consider the rates 45 mile in 8 minutes and 4 minutes to travel 25 mile. Select the statement(s) that are true. Multiple select question. Cross out A) The rate 45 mile in 8 minutes has a unit rate of 10 miles per minute. Cross out B) The rate 45 mile in 8 minutes has a unit rate of 110 mile per minute. Cross out C) The rate 4 minutes to travel 25 mile has a unit rate of 10 minutes per mile. Cross out D) The rate 4 minutes to travel 25 mile has a unit rate of 110 minute per mile. Cross out E) Both rates are equivalent. Cross out F) The rates are not equivalent.
Answer:
F) The rates are not equivalent.
Step-by-step explanation:
Consider the rates 45 mile in 8 minutes and 4 minutes to travel 25 mile. Select the statement(s) that are true. Multiple select question.
We find the unit rates
a) 45 mile in 8 minutes , we find the unit rate in miles per minute
8 minutes = 45 miles
1 minute = x
8 × x = 45 miles × 1 minute
x = 45 miles/8 minutes
x = 5.625 miles/ minute
b) 4 minutes to travel 25 miles. Find the unit rate is minutes per mile
25 miles = 4 minutes
1 mile = x
25miles × x = 4 minutes × 1
x = 4 minutes/25 miles
x = 0.16 minutes/mile
Hence, the correct option is
F) The rates are not equivalent.

What is the equation of the line that passes through the point (3,-3)(3,−3) and has a slope of 0?
Answer:
The equation of the line that passes through the point (3,-3) and has a slope of 0 will be:
[tex]0=y+3[/tex]
Step-by-step explanation:
The point-slope form of the equation of a line is:
[tex]\:y\:-\:y_1\:=\:m\left(x-x_1\right)[/tex]
where
[tex]m[/tex] is the slope of the line and, [tex]\left(x_1,\:y_1\right)[/tex] is a point on the line.As the slope is [tex]m=0[/tex], and the point is [tex](3,-3)[/tex]
so
Equation of the line will be:
[tex]\:y\:-\:y_1\:=\:m\left(x-x_1\right)[/tex]
[tex]y\:-\:\left(-3\right)\:=\:0\left(x-3\right)[/tex]
Further simplifying
[tex]0=y-\left(-3\right)[/tex]
[tex]0=y+3[/tex]
Therefore, the equation of the line that passes through the point (3,-3) and has a slope of 0 will be:
[tex]0=y+3[/tex]
What is 1/6 as a decimal rounded to 3 decimal places?
Answer:
1/6 or 0.16666... can be written rounding off to three decimal digits such as:
[tex]0.16666...[/tex] [tex]\approx[/tex] [tex]0.167[/tex] (rounding off to three decimal digits)Step-by-step explanation:
As we know that
[tex]1\div 6\:=\:0.16666\dots \:[/tex]
In order to round off three decimal places (or digits ), we need to check:
the digit in the fourth place.If the digit in the fourth place is greater than 5, then we must add 1 to the previous digit.Therefore, 1/6 or 0.16666... can be written rounding off to three decimal digits such as:
[tex]0.16666...[/tex] [tex]\approx[/tex] [tex]0.167[/tex] (rounding off to three decimal digits)The fraction 1/6 expressed as a decimal number is 0.167
Fractions are expressed as the ratio of two integers. For example, a/b is a fraction where a and b are integers
Given the fraction 1/6, we are to express it as a decimal.
First, we can express it as a percentage as shown:
1/6 * 100 = 100/6
1/6 = 16.7%
Expressing as a decimal number
16.7% = 0.167
Hence the fraction 1/6 expressed as a decimal number is 0.167

how many solutions do the equations y=3x+4 and 3y-6x=2 have?
Answer:
1 solution
Step-by-step explanation:
You can solve these equations by using substitution. y = 3x+4, so 3y-6x=2 can also be written as 3(3x+4)-6x = 2 if you plug in the y value in the second equation. Then, simplify and you will get your x answer. If you plug that into the first equation, you will get your y answer.

g(7)=
Answer:
g(7) = 4
General Formulas and Concepts:
Algebra I
Reading a Cartesian PlaneWriting CoordinatesStep-by-step explanation:
What g(7) is saying is that we are trying to find the y-value when x = 7. According to the graph, when x = 7, y would equal 4. Therefore, g(7) = 4 and our coordinate would be (7, 4).
You need to know that g(7) means that x = 7. Look at the graph. When x is 7, what is the value of y?
The point (7,4) indicates that g(7) = 4.

g(n) = -n+ 3
How do you find the inverse of this equation?
Let g(n) = y
We then have y = -n + 3.
Exchange y and n.
n = -y + 3
Solve for y.
n - 3 = -y
(n - 3)/(-1) = -y/(-1)
-(n - 3) = y
Replace y with g^(-1) n.
-(n - 3) = g^(-1) n

Name a point NOT on line l or m
find all angles and pls show steps
Answer:
Both angles have a measure of 134degrees, y = 27degrees.
Step-by-step explanation:
As per what is given in the problem:
There are 2 parallel lines, both are intersected by a transversal.
Remember the theorem, when two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.
The is meanse that:
3y + 53 = 7y - 55
Solve using inverse operations:
3y + 53 = 7y - 55
+55 +55
3y + 108 = 7y
-3y -3y
108 = 4y
/4 /4
27 = y
Now, substitute back in to find the value of the angle:
3y + 53
y = 27
3 ( 27 ) + 53
81 + 53
= 134
Since the angles are alternate exterior, they are congruent, hence both angles have a measure of 134degrees.

Tim throws a stick straight up in the air from the ground. The function h = -16t^2+ 48t models the height, h, in feet, of
the stick above the ground after t seconds. Which inequality can be used to find the interval of time in which the stick
reaches a height of more than 8 feet?
Answer:
[tex]-2t^2+ 6t -1 > 0[/tex]
Step-by-step explanation:
Function Modeling
The height h in feet of the stick threw by Tim is modeled by the function:
[tex]h = -16t^2+ 48t[/tex]
where t is the time in seconds.
It's required to write an inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet, i.e. h > 8.
Using the given model, we write the inequality:
[tex]-16t^2+ 48t > 8[/tex]
Dividing by 8
[tex]-2t^2+ 6t > 1[/tex]
Subtracting 1, we get the required inequality:
[tex]\mathbf{-2t^2+ 6t -1 > 0}[/tex]
Answer:
you want more than 8 feet so the answer would be -16t^2+48t>8
Step-by-step explanation:
h=-16t^2+48t
-16t62+48t>8
-16t^2+48t=8
divide both sides of the equal sighn by 8
-2t^2+6t=1
put the symbol back in
-2t^2+6t>1
substitute a random mumber for t
-2(5)^2+6(5)>1
-10^2+30>1
subtract 30 from both sides
100>-29
state is true so -16t62+48t>8 is the correct answer

Miguel sells boxes of cookies for $8 each. Donna sells boxes of cookies for $10 each. Each of them sold the same dollar amount. It was the smallest dollar
amount for which this was possible.
Answer the following questions.
How many boxes did Miguel sell?
Answer:
$40
Step-by-step explanation:
You find the LCM (least common multiple). To do this, you can use prime factorization.
(there is an below that shows the prime factorization tree for 8 and 10)
so, the only common prime factor is 2. you use the 2 and multiply with the remaining prime factors.
5*2 --> for 10
2*2*2 -->for 8
becomes
5*2*2*2
if you multiply that out, it becomes 40.
Another method is to just think: "What can they both become after being multiplied by a number?" or "What can 8 and 10 both be?"
Anyway, the answer is 40. Hope this helps!
