Answer:
Any value of m, except when m = -12.7, will make the expression equal to 6.35
Step-by-step explanation:
The equation you are given is:
6.35 = 12.7 + m / m + 12.7
First you need to know the rule that anything divided by itself will equal 1.
So no matter what number you use to substitute for m it will equal one because both the top and bottom of the division sign are the same. Except if you use negative 12.7 or a to high of a negative which will cause it to equal -1 which multiplied by 6.35 would equal -6.35

Answers
The unknown number will be 4 for the given expression.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that there is a number such that four times the number plus 3 is equal to 19.
The number will be calculated by writing the mathematical expression below assuming the unknown number is x.
4x + 3 = 19
4x = 19 - 3
4x = 16
x = 16 / 4
x = 4
Therefore, the unknown number will be 4 for the given expression.

F A taxicab company charges $2.80 plus $0.40 per mile. Carmen paid a fare of $8.80. Enter and solve an equation to find the number of miles she traveled. Use m as your variable.
Answers
Answer:
15 miles
Step-by-step explanation:
8.80-2.80=6
6/0.40=15 miles
m = miles traveled.
$2.80 + $0.40m = $8.80
Subtract $2.80 from both sides.
$0.40m = $6.00
Divide both sides by $0.40
m = 15
Carmen traveled a total of 15 miles.

Lynn is making custom bricks. She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket. She spills 13 pounds of the mixture while stirring the contents. The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture, and the leftover mixture is washed out of the mixing bucket.
What is the greatest number of bricks Lynn can make?
___ bricks
How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?
___ pounds
Answers
Answer:
A. 10 bricks
B. 4 pounds
Step-by-step explanation:
Water = 39 pounds
brick dust = 48 pounds
Total mixture = water + brick dust
= 39 + 48
= 87 pounds
She spills 13 pounds of the mixture while stirring
Remaining mixture = Total mixture - Spillage
= 87 pounds - 13 pounds
= 74 pounds
The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture
Number of bricks made = Remaining mixture / pounds per brick
= 74 pounds / 7 pounds
= 10 bricks remaining 4 pounds of the mixture
A. What is the greatest number of bricks Lynn can make?
10 bricks
B. How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?

if f(x) = -x^2+4x-9 and g(x) = x - 8 find g(f(-1)).
Answers
Answer: g(f(-1))=-22
Step-by-step explanation:
To find g(f(-1)), you want to first want to solve f(-1). Once you solved that, you plig the answer you get into g(x). Then, you will have your final answer.
f(-1)=-(-1)²+4(-1)-9 [exponent]
f(-1)=-1+4(-1)-9 [multiply]
f(-1)=-1-4-9 [subtract from left to right]
f(-1)=-14
We have found that f(-1)=-14. Now, we know in -14 into g(x) and solve.
g(-14)=(-14)-8 [subtract]
g(-14)=-22
Now, we know that g(f(-1))=-22.

For Part 1:(+6) + (-5) = 6 - 5 = 1 (P)
(+6) + (-9) = 6 - 9 = -3 (N)
(-6) + (-4) = -6 - 4 = -10 (N)
(+6) + (-2) = 6 - 2 = 4 (P)
Part 2:(-7) + (+1) + (+2) = -7 + 1 + 2 = -4
(-2) + (-4) + (+3) = -2 - 4 + 3 = -3
(+5) + (+3) + (-1) + (-4) = 5 + 3 - 1 - 4 = 3
(-4) + (+3) + (-2) + (-6) = -4 + 3 -2 - 6 = -9

Which statement best describes the function?
A. The function is positive when x<0.
B. The function is always positive.
C. The function is positive when x < 0 and when x > 0.
D. The function is positive when x > 0.
Answers
Answer:
The correct option is;
D. The function is positive when x > 0
Step-by-step explanation:
The reciprocal parent function is of the form;
[tex]y = \dfrac{a}{x - h} + k[/tex]
Where;
h = The horizontal translation
k = The vertical translation
a = The orientation of the graph
Therefore, whereby we have, h = 0, k = 0. and a = 1, the equation becomes;
[tex]y = \dfrac{1}{x - 0} + 0 = \dfrac{1}{x}[/tex]
Therefore, the value of the function y is positive when x > 0 and is negative when x < 0.
