Answer:
-3/5
Step-by-step explanation:
-2/5+-1/5= -3/5
I used a calculator to ensure this answer was correct
This is because -2 pulse -1 is -3. And you can’t add the denominator if it’s the same. In this case the denominators are the same so u keep it as 5. So the answer would be A

Hi! Would you guys mind anderring this? A submarine is at a depth of 100 feet below sea level. Then it starts to dive at a rate of 50 feet per minute. What is the slope?
Answers
Answer:
slope (m) = -50 or -50x
Step-by-step Explanation
I'm assuming that the x-axis is divided by 1 minute segments.
The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"
Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute
Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for
Answer:
Independent variable: Time in minutes
Dependent variable: The elevation in feet
Slope: -50

what is the standard form for the equation y=-5x+8
Answers
Answer
5x+y=8
Step-by-step explanation:
[tex]y + 5x = 8[/tex] is a standard form of equation.
What is standard form?
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. If the equation is given in this form, finding both points of intersection (x and y) is quite easy. This form is also very useful for solving systems of two linear equations.
By some examples,we can understand the concept more easily.
Example -1,
[tex]2x + 3y = 2[/tex] is a standard form of equation.
Example -2,
[tex]5x + 7y = 2[/tex] is a standard form of equation.
Example -3,
[tex]5x = y - 5[/tex] is not a standard form of equation.
Given equation is [tex]y = - 5x + 8....(1)[/tex]
We want to find standard form for the given equation.
Now,
[tex]y = - 5x + 8[/tex]
We are separating variable and constant part.
[tex]y + 5x = 8[/tex]
According to rule,it is a standard form of equation.

Mr. Morales purchases 6 boxes of pencils, 12 boxes of pens, and 4 cases of notebook paper for his classroom. Each box of pencils costs $4.10, each box of pens costs $6.50, and each case of notebook paper costs $105. What is the total cost in dollars of his classroom supplies?
Answers
Answer:
$522.60
Step-by-step explanation:
pencils: $4.10 * 6 ===> $24.60
pens: $6.50 * 12 ===> $78
notebook paper: $105 * 4 ===> $420
pencils + pens + notebook paper = total cost
24.60 + 78 + 420 = 522.60
In a three-digit number, the tens digit is the same as the hundreds digit. The ones digit of this number is equal to 1/3 of the sum of the other two digits. Find the number if the sum of all its digits is equal to 24.
Answers
Answer:
The three digit number is;
996
Step-by-step explanation:
The three digit can be written xyz
ones digit is equal to 1/3 the sum of the two other digits
z = 1/3(x + y)
x + y + z = 24
Tens digit is same as hundreds digit
That means x = y
z = 1/3 (x + x) = 2x/3
So;
2x/3 + x + x = 24
Multiply through by 3
2x + 3(2x) = 72
8x = 72
x = 72/8

ZA= 63 - 189
ZB = 142 + 38°
Solve for x and then find the measure of ZA:
Answers
Answer:
∠A = 30°Step-by-step explanation:
∠A + ∠B = 180
where ∠A = 6x - 18
∠B = 14x + 38
first step is to solve for x:
6x - 18 + 14x + 38 = 180
6x + 14x = 180 + 18 - 38
20x = 160
x = 160 / 20
x = 8
now substitute x=8 into angle A
∠A = 6x - 18
∠A = 6(8) - 18
∠A = 30°
If f(x) = -3, then x = _____ .
Answers
Answer:
x = -5
Step-by-step explanation:
f(x) is the same thing as y. so when y=-3, find that point and the x is -5
The answer to the given problem can be stated as, "If f(x) = -3, then x = -5.
What is a function?A function y = f(x) is defined as a one to one relation between sets X and Y. The set X is called the domain while Y is called the range of f(x).In order to find the different values of f(x) for different x on a graph, draw perpendicular lines to both the axis.
The graph given in the problem shows different points lying on it.
In order to find the value of x at f(x) = -3, draw a perpendicular line from the graph at which the value of f(x) is -3.
The x coordinate obtained is given as x = -5.
Hence, the required value of x at f(x) = -3 is -5.

what is g(3)=
?????
Answers
Answer:
g(3) = 4
Step-by-step explanation:
The question means what is the value of y when x = 3
Locate x = 3 on the x- axis. Go vertically up until the dot is met and read off the corresponding value on the y- axis, that is y = 4
Thus when x = 3 then y = 4, or
g(3) = 4
The value of g(3) from the graph given is 4
The given diagram is a graph in the xy-plane with different coordinate points.
g(x) is the output value of the function for an input value of x.Th order to get g(3), this means that we need to get the corresponding y-value for the value of x.The point that has an x-coordinate of 3 is the point o the coordinate (3, 4). Hence the required value of y when x = 3 is 4.Hence we can conclude that the value of g(3) is 4
