Answer:
m = 3
Step-by-step explanation:
Notice what has been done to the variable. It has been multiplied by 3, then 1 is added to the product.
We solve an equation like this by undoing those operations, in the reverse order. First, we undo the addition of +1 by adding -1 (the opposite of +1) to both sides of the equation.
3m + 1 - 1 = 10 - 1
3m = 9 . . . . . . . . . simplify
__
Now, we undo the multiplication by 3 by multiplying by the "multiplicative inverse" or reciprocal, 1/3. This is the same as dividing by 3.
(1/3)(3m) = (1/3)(9)
As before, we do this to both sides of the equation.
m = 3 . . . . . . . . . simplify
The solution is m = 3.
_____
The rule for equations is that you must do the same operation to both sides of the equation in order for it to remain valid. (The same is true for inequalities, with a special rule for multiplication or division by a negative number. Doing that reverses the comparison symbol: < ⇔ > or ≤ ⇔ ≥.)

The factored form of a quadratic function is f(x)=(x-p)(x-q).The standard form of a quadratic function is fX)=ax^2+bx+c. The factored
form for a quadratic function tells us the x-intercepts of the quadratic function, while the standard form for a quadratic function tells us they
intercept of the quadratic function.
If p=2 and q=-3, use what you have learned about multiplying polynomials to
1) write the factored form of the quadratic function f(x)
2) write the standard form for the quadratic function f(x)
Answer:
(1) f(x)=(x-2)(x-3)
(2) f(x)=x²-5x+6
Step-by-step explanation:
(1) f(x)=(x-p)(x-q)
f(x)=(x-2)(x-3)
(2) f(x)=x²-3x-2x+6
f(x)=x²-5x+6

4. Show that Polygon A is congruent to Polygon B.
A is equivalent to B because if you flip or reflect A, then translate A it overlaps.
1. Draw A's reflection below it: as if you flipped it.
2. Take the drawing and draw it mirroring B
3. Once you draw the second drawing if you moved, translated, it it would fit over the shape of the B polygon.

find area of circle
Answer:
should be 314.16 possible that is incorrect because I calculated it by pie and not by 3.
Answer:
A = 314 cm^2
Step-by-step explanation:
A = pi x r^2
A = 3.14 x (10 x 10)
A = 3.14 x 100
A = 314 cm^2

The sides of two similar polygons are in the ratio of 5 : 2. If the area of the smaller polygon is 576 ft2 , what is the area of the larger polygon?
I got 1,440 ft. Is this right?
Answer:
No, 1440 is wrong. The correct answer is 3600
Step-by-step explanation:
A = [tex]a^{2} / b^{2}[/tex]
{(5) / (2)} ^ (2) * 576

Jose's school is selling tickets to a choral performance. On the first day of ticket sales
the school sold 3 adult tickets and 7 child tickets for a total of $132. The school took
in $141 on the second day by selling 4 adult tickets and 7 child tickets. What is the
price each of one adult ticket and one child ticket?
Step-by-step explanation:
let x be the price of the adult ticket and y the price of child ticket
so
3x+7y=132
4x+7y=141
from the first equation 7y=132-3x
lets replaxe this from the second equation
4x+(132-3x)=141
4x-3x=141-132
x=9
so knowing that 7y=132-3x
7y=132-3*9
7y=105
y=105/7=15
so finaly the adult ticket cost 9 dollars and child ticket cost 15 dollars
Find the slope of the line that passes through the points (-7,-5) and (4, -3).
Answer:
