Answer:
y=2x
Step-by-step explanation:
y = kx is the format of the graph we are looking for (as told in the instructions) where k is the variable we are supposed to find (like y = x, y=2x, y=3x, etc)
Note that as x increases by 1, y increases by 2. We can see that by writing a table of the points of points that the line given intersects (picture below). We can see that by the values of the x-axis and the y-axis. Why does this happen? This is because y =2x for each value of x. We notice that in our table.
Therefore, the equation is y=2x. I hope this helps! If you still have questions, ask me in the comments!
What is RU?
A.20
B.30
C.12
D.15
Answer:
a
Step-by-step explanation:
The segment RT is a perpendicular bisector and means Δ RSU is isosceles, then the 2 legs are congruent, that is
RS = RU , substitute values
8x = 6x + 5 ( subtract 6x from both sides )
2x = 5 ( divide both sides by 2 )
x = 2.5
Thus
RU = 6x + 5 = 6(2.5) + 5 = 15 + 5 = 20 → a

Step-by-step explanation: This is just a guess so I may be wrong. So when I put this into the calculator, it is showing a big number: 73.58485333 so what I did was round it to the nearest hundredths which is 73.58 so hope this helps somebody :)
tell whether the ordered pair is a solution to the system of inequalities
Answer:
Yes, it is
Step-by-step explanation:
The solution to the inequality are the sets of points that lie where we have the shaded part
The coordinates (3,0) lie on the shaded part and thus will be a solution to the set of inequalities

radioactive isotope, how much will be left after 5 half-lives?
Use the calculator provided and round your answer to the nearest gram.
grams
Answer:
divide 195 by 2 , 5 times. Or 195 × 0.5^5
What is an equation of the line that passes through the point (-2, -6) and is
parallel to the line x + 2y = 8?
Answer:
The equation of new line is: [tex]\mathbf{y=-\frac{1}{2}x-7}[/tex]
Step-by-step explanation:
We need to write an equation of the line that passes through the point (-2, -6) and is parallel to the line x + 2y = 8
We need to find slope m and y-intercept b for the new line.
First we need to find slope m of the new line.
The given line x+2y=8 is parallel to new line.
When lines are parallel, there slope is same.
First writing equation in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept
[tex]x+2y=8\\2y=-x+8\\y=-\frac{1}{2}x+\frac{8}{2}\\ y=-\frac{1}{2}x+4[/tex]
Now comparing with [tex]y=mx+b[/tex] the slope is : [tex]m=-\frac{1}{2}[/tex]
Now finding y-intercept b
Using point (-2,-6) and slope [tex]m=-\frac{1}{2}[/tex] we can find y-intercept
[tex]y=mx+b\\-6=-\frac{1}{2}(-2)+b\\-6=1+b\\b=-6-1\\b=-7[/tex]
So, we get y-intercept b = -7
Now the equation of required line having slope [tex]m=-\frac{1}{2}[/tex] and y-intercept b = -7 is:
[tex]y=mx+b\\y=-\frac{1}{2}x-7[/tex]
So, the equation of new line is: [tex]\mathbf{y=-\frac{1}{2}x-7}[/tex]

If x = 7, what is the value of the expression above?
Answer:
5
Step-by-step explanation:
12-7=5
Answer:
5
Step-by-step explanation:
We know that x is equal to 7. That means we can replace x with this value. This makes our new expression:
12 - 7
12-7 is equal to 5, so this expression will equal 5 when x = 7.
Solve for x:
4(1 – x) + 2 x = -3( x + 1)
Answer:
4(1 – x) + 2 x = -3( x + 1)
first do 4 time 1= 4
then do 4 times x =4x
now the equation should look like this
4-4x+2x=-3(x+1)
then do the other side of the equation
-3(x+1)
=-3x-3
Now collect the like terms:
-4x-2x
now the equation should look like this
4-2x=-3x-3
now add 3x add on both sides
4-2x+3x=-3
put the 4 on the other side
-2x+3x=-3-4
now again collect the like terms (-2x+3x=1 which is just x and -3-4 =-7)
x=-7
answer
x=-7
Answer:
[tex]x=-7[/tex] PLEASE MARK ME AS BRAINLIEST
Step-by-step explanation:
[tex]4(1-x)+2x=-3(x+1)[/tex]
Distribute 4 through the parentheses
[tex]4-4x+2x=-3(x+1)[/tex]
Distribute -3 through the parentheses
[tex]4-4x+2x=-3x-3[/tex]
Collect like terms
[tex]-4x+2x[/tex]
Collect like terms by calculating the sum or difference of their coefficient
[tex](-4+2)x[/tex]
Calculate the sum
[tex]-2x[/tex]
[tex]4-2x=-3x-3[/tex]
Move variable to the left hand side and change its sign

Why move an expression to the right?
We want to move an expression to the right to write the equation in a specific way.
The opposite needs to be added to both sides to preserve the relation between the sides. That is called the addition and subtraction property of equality/inequality
Step 1
Example
take the equation:
[tex]x+a=b[/tex]
We want the expression a to be on the right hand side of the equation.
Step 1
example(cont)
To move the expression to the right -hand side, use the addition property , and add -a to both sides of the equation:
[tex]x+a+(-a)=b+(-a)[/tex]
Simplify the left hand side and remove the parentheses on the right hand side:
[tex]x+a+(-a)=b+(-a)\\x=b-a[/tex]
Now the expression a is on the right hand side :
[tex]x=b-a[/tex]
Step 2:
Notice! when comparing the beginning and the ending equation, it seems like we just moved the expression to the right hand side and changed its sign:
[tex]x+a=b\\x=b-a[/tex]
This is a shorter way to use the same property.
Now came back to the original equation
[tex]4-2x+3x=-3[/tex]
Move constant to to the right hand side and change its sign
[tex]-2x+3x=-3-4[/tex]
collect like terms
[tex]x=-3-4[/tex]
calculate the difference
[tex]x=-7[/tex]
Why move a constant to the right?
We want to move a constant to the right because the mathematicians agreed upon a convention that the constants in the equation and inequalities always need to be on the right-hand side.
The opposite needs to be added to both sides to preserve the relation between the sides. That is called the addition and subtraction property of equality/inequality.
Step 1
example
Take the equation:
[tex]x+3=5[/tex]
We want the constant 3to be on the right hand side of the equation.
Step 1
example (cont)
To move the constant to the right-hand side, use the addition property, and add -3 to both sides of the equation:
[tex]x+3+(-3)=5+(-3)[/tex]
Simplify the left-hand side and remove the parentheses on the right - hand side:
[tex]x+3+(-3)=5+(-3)\\x=5- 3[/tex]
Now , all the constants are on the right- hand side:
[tex]x=5-3[/tex]
Step 2
Notice! when comparing the beginning and the ending equation, it seems like we just moved the constants to the right hand side and change its sign:
[tex]x+3=5\\x=5-3[/tex]
This is a shorter way to use the same property.

Answer: 4^9
Step-by-step explanation:
4^-7 is just 1/4^7 so this is equal to 4^2 divided by 1/4^7. Dividing by a fraction is the same thing as multiplying by its reciprocal (just flip the fraction). So this whole equation is equal to 4^2 multiplied by 4^7. And when you multiply two exponents with the same base, the exponents are just added. So, your answer should be 4^9. Hope this helps! :)

The two triangles are congruent through AA (angle-angle proportionality theorem) therefore all the sides are congruent to each other.
In this case:
2y = 5y - 7
2y - 5y = -7
-3y = -7
y = -7/-3
y = 7/3
