Answer:
-32r+3
Step-by-step explanation:
You have to combine -9r+2r-5r-20r, orrrr…
you can remove the variables and solve:
[tex]-9+2-5-20=\\ -32[/tex]
then add the variable back,
[tex]-32r[/tex]
since the +3 has no variable, you can’t add it to -32r
so…
you have to add it to the equation as a separate term:
[tex]-32r+3[/tex]

if f(x) = 2x^2 +1 and g(x) = 3x-2 what is the value of f(g(x))
Answer:
18x² - 24x + 9
Step-by-step explanation:
To find f(g(x)), substitute x = g(x) into f(x) , that is
f3x - 2)
= 2(3x - 2)²+ 1 ← expand factor using FOIL
= 2(9x² - 12x + 4) + 1 ← distribute parenthesis by 2
= 18x² - 24x + 8 + 1
= 18x² - 24x + 9

A line has a slope of 0 and passes through the point (10, 2). What is its equation in slope intercept form?
Answer:
y = 10
Step-by-step explanation:
y = m x + C, where m is the slope and c is the intercept on the y axis. Plugging in the values of m and C, we get: y = 0 x + 10 = 0 + 10 = 10. Therefore, y = 10.
The equation of line that passes through the point P ( 10 , 2 ) and has a slope of 0 is y = 2
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the point be represented as P ( 10 , 2 )
And ,let the slope of the line be m = 0
Slope m = 0
Now , the equation of line is given by the formula y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 2 = 0 ( x - 10 )
On simplifying the equation , we get
y - 2 = 0
Adding 2 on both sides of the equation , we get
y = 2
Therefore , the value of A is y = 2
Hence , the equation of line is y = 2

Step-by-step explanation:
Triangle J K L is shown. Point M is the midpoint of side K L and point J is the midpoint of side J L. The length of K J is 12. 8 meters, the lengths of J N and N L are 3. 7 meters, and the lengths of K M and M L are 5. 9 meters. Which statements about triangle JKL are true? Select two options. M is the midpoint of line segment KJ. N is the midpoint of line segment JL. MN = One-halfKJ MN = 4. 4m MN = ML.
The true statements are: M is the midpoint of line segment KJ and N is the midpoint of line segment JL
The given parameters are:
[tex]KJ = 12.8m[/tex]
[tex]JL = 7.4m[/tex]
[tex]KL = 11.8m[/tex]
From the figure (see attachment), we have the following highlights

Answer:
Both first and second one are not true.
Step-by-step explanation:
The first one translates to "101 is less than 100". This statement is false.
Second one translates to " 101 is equal to 0". Obviously, this isn't true.

A set of 3 consecutive integers has a sum of 15. Which integers are they?
The answer is 4+5+6=15.Hope that helps. :)
Answer:
Step-by-step explanation:
Let the first number be x,
The second number (since it is consecutive) will be = x + 1
The third number (since it is right after the second) = (x+1) + 1 = x + 2
x + x + 1 + x + 2 = 15
3x + 3 = 15
3x = 15 - 3
3x = 12
x = 12/3 = 4
If the first number = 4,
Second number will be = 5 [(x+1) = 4+1]
Third number will be = 6 [(x+2) = 4 + 2]

is y = 2/3x - 7 proportional or not?
Answer: No, it is not a direct proportion equation
Explanation:
Direct proportions are always in the form [tex]y = kx[/tex] where k is any nonzero real number. So for example, we could have the equation [tex]y = 9x[/tex]. The y intercept of any direct proportion is always zero. Visually, such equations will go through the origin.
Something like [tex]y = \frac{2}{3}x-7[/tex] has a y intercept of -7 and it doesn't fit the form [tex]y = kx[/tex], so it's not a direct proportion equation.
