4. Given: a + m = n, n= 4a; Prove: m = 3a
Answer:
Proof below
Step-by-step explanation:
Algebraic Manipulation
It refers to the process of modifying algebraic expressions, often into a simpler form or more easily handled and dealt with.
It also helps us to prove some identities.
We are given the relations:
a + m = n
n = 4a
Substituting the last equation in the first, we have:
a + m = 4a
Subtracting a on both sides of the equation:
m = 4a - a
Simplifying:
m = 3a
Hence proved

maximum and minimum value
9514 1404 393
Answer:
maximum: 8; no minimum
Step-by-step explanation:
A graph can be useful. I find a graphing calculator handy. It shows the maximum of the function is f(-1) = 8. Since the parabola goes to -∞ for large values of x, there is no minimum.
maximum: 8
__
You can also find the maximum by putting the function in vertex form.
-3(x^2 +2x) +5 . . . . factor the leading coefficient from the x terms
-3(x^2 +2x +1) +5 -(-3)(1) . . . . add the square of half the x-coefficient, subtract the equivalent amount
-3(x +1)^2 +8 . . . . . . the vertex form of the expression for f(x)
This form is ...
a(x -h)^2 +k . . . . . with a=-3, h=-1, k=8
so the vertex is (h, k) = (-1, 8) -- the same as shown on the graph. The negative value of 'a' tells you the parabola opens downward, so the vertex is the maximum. The maximum is 8 at x = -1.

(100, 64, x )
Answer:
I don't think it's any of them, is it supposed to add up to 180? If so 100 + 64 obviously equals 164, and 164 -180 equals 16 but there's no 16 as an answer choice
8x+ 7y =39
8x + 2y = 34
What is x and y
Answer:
y= 1 and X=4
Step-by-step explanation:
8x +7y =39
8x +2y =34
elimination method(we multiply 8x+7y=39 or 8x + 2y= 34 by -1 to eliminate 8x)
lets multiply 8x+7y = 39 by - 1
-8x -7y = -39
8x +2y = 34
(8x-8x)+(2y-7y)= (-39+34)
0 + (-5y) = -5
-5y= -5......dividing both sides by -5
y = 1
8x +2y =34....... substituting y by 1
8x +2(1)= 34
8x + 2= 34
8x = 34-2
8x = 32.....dividing both sides by 8
x = 4
Lets check;
8x +2y = 34
8(4) +2(1) = 34
32 + 2 =34
34 = 34
8x + 7y = 39
8(4) + 7(1) = 39
32 + 7 =39
39 = 39
find the value of x. What kind of angles are these?
Answer:
[tex]\displaystyle Corresponding\:Angles; 40 = x[/tex]
Step-by-step explanation:
Corresponding Angles are congruent, therefore you set both angle measures equal to each other:
[tex]\displaystyle 135° = [3x + 15]° → 120 = 3x; 40 = x[/tex]
I am joyous to assist you at any time.
Hey there!
The answer to your question is [tex]x = 40[/tex]
These are two parallel lines cut by a transversal, which means that they are corresponding angles and, therefore, [tex](3x + 15)[/tex] is equal to [tex]135[/tex]°:
[tex]3x + 15 = 135[/tex]
Subtract [tex]15[/tex] from both sides:
[tex]3x = 120[/tex]
Divide both sides by [tex]3[/tex]:
[tex]x = 40[/tex]

In a video game, Clare scored 50% more points than Tyler. If c is the number of points that Clare scored and t is the number of points that Tyler scored, which equations are correct? Select all that apply.
c = 1.5t
c = t + 0.5
c = t + 0.5t
c = t + 50
c = (1 + 0.5)t
Answer:
c = t + 0.5t
c = (1 + 0.5)t

Answer:
[tex]^{15} C_{5} = 3,003 \\[/tex]
Step-by-step explanation:
here , we want to evaluate the value of 15 combination 5
Mathematically, we have the general combination formula as follows;
[tex]{n} C^{r} =\frac{n!}{(n-r)!r!}[/tex]
In this case , n is 15 and r is 5
Thus , we have it that;
[tex]^{15} C_{5} = \frac{15!}{(15-5)!5!} \\= \frac{15!}{10!5!} =\frac{15x14x13x12x11x10!}{10!5!} \\=\frac{15x14x13x12x11}{5!} \\\frac{15x14x13x12x11}{5x4x3x2xx1}=3,003\\[/tex]

Answer:
C
Step-by-step explanation:
Key skills needed: Understanding inequalities, Understanding variables
1) The inequality is [tex]120\geq 12x + 29[/tex]
2) This means that 12x + 29 is at most 120, not at least. At least means greater than or equal to. At most means less than or equal to.
3) 29 is the initial amount --> So C is the answer. C says that 29 is the initial amount, and 12 coins are being added every year (k is the number of years). C also says "AT MOST".
Therefore C is the answer
