The table represents a linear function.What is the slope of the function?
The graph is X, -2,-1,0,1,2 and Y, -2,1,4,7,10
Answer:
the slope is 4/3
Step-by-step explanation:
use the formula:
m=[tex]\frac{y1-y2}{x1-x2}[/tex]
where x1 and y1 can be any point and x2 and y2 can be any point.
I used the last relation as my x1,y1 and second last relation as my x2,y2 because it is easier to subtract them.
[tex]\frac{10-2}{7-1}[/tex] which is 8/6 or 4/3

The list price of an item is $ 93.45. The supplier is offering a series trade discount of 7/23. Find the net cost.
Answer: $66.92
Step-by-step explanation:
We can get the final price by calculating the first discount and then subtracting this from the original price to get the amount to which the second discount is applied. We can then determine the final price by subtracting the second discount from the intermediate price.The percent of the first discount is 7.
The price after the first discount is $93.45−($93.45×0.07)=$86.91.
The price to which the second discount is applied is $86.91.
The second discount is 23%
86.91 x 0.23 = $19.99
The final price is (86.91 - 19.99) = 66.92
The proportion of brown M&M's in a milk chocolate packet is approximately 14% (Madison, 2013). Suppose a package of M&M's typically contains 52 M&M's
Answer:
About 7 brown M&M's.
Step-by-step explanation:
To find 14% of 52, multiply 0.14 * 52. This equals 7.28, round to 7.

!!WILL MARK BRAINLIEST!! Write in slope-intercept form an equation of the line that passes through the given points.
Answer:
y = 1/4x
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= (2-1)/(8-4)
= 1/4
The slope intercept form of a line is
y = mx+b
where m is the slope and b is the y intercept
y = 1/4x +b
Substitute a point into the equation
1 = 1/4(4) +b
1 = 1+b
b= 0
y = 1/4x

Answer:
[tex]length = 12ft[/tex]
Step-by-step explanation:
Given that,
[tex]width =9 \frac{1}{2} = 9.5[/tex]
Let's find the length
[tex]perimeter \\43 = 2(l + w) \\ 43= 2(l + 9.5) \\ 43 = 2l + 19 \\ 43 - 19 = 2l \\ 24 = 2l \\ \frac{24}{2} = \frac{2l}{2} \\ l = 12[/tex]
hope this helps

HELP ME OUT! A student dissolves 1 gram of sugar in 10 grams of water. She then determines the mass of the solution. What is the mass of the dissolved sugar and water?
Answer:
The mass of the dissolved sugar and water is 11 g.
Step-by-step explanation:
When a substance is dissolved in another, they are mixed together forming a new one, therefore the new substance's mass must be the same as the sum of the individual mass of each substance mixed, because there are no leaks. In this case, there are two substances being mixed, the water which have a mass of 10 grams and the sugar which have a mass of 1 gram, therefore the final solution's mass must be equal to 11 g.

You roll a twelve-sided die (having values one through twelve on its faces). What is the probability that the value of the roll will be a composite number?
show work pls!
help pls!
Step-by-step explanation:
Probability
Probability is a measure of the likelihood that an event will happen.
When dealing with probability, the outcomes of a process are the possible results. For example, when a die is rolled, the possible outcomes are 1, 2, 3, 4, 5, and 6. In mathematical language, an event is a set of outcomes, which describe what outcomes correspond to the "event" happening. For instance, "rolling an even number" is an event that corresponds to the set of outcomes {2, 4, 6}. The probability of an event, like rolling an even number, is the number of outcomes that constitute the event divided by the total number of possible outcomes. We call the outcomes in an event its "favorable outcomes".
Probability =
I need help ASAP!! A, B, C, D
Answer:
C. Both f(x) and its inverse function intersect at point (2, 2).
Step-by-step explanation:
First of all, let's begin defining f(x) = y.
Since the linear function f(x) intersects at
• 6 on the y-axis; and
• 3 on the x-axis;
we can deduce the following equation:
6x + 3y = 6(3)
6x + 3y = 18
3y = -6x + 18
y = -6x/3 + 18/3
y = -2x + 6
f(x) = -2x + 6
Then, we'd want to find the inverse of f(x), which is f`¹(x).
f(x) = -2x + 6
y = -2x + 6
Interchange the variable y to x and vice versa.
x = -2y + 6
2y = -x + 6
y = (-1/2)x + 3
f`¹(x) = (-1/2)x + 3
Since both f(x) and its inverse function are equal to y, set them both as equal.
f(x) = f`¹(x)
-2x + 6 = (-1/2)x + 3
-2x + (1/2)x = 3 - 6
(-3/2)x = -3
x = 2
Substitute x = 2 into y = -2x + 6.
y = -2(2) + 6
y = -4 + 6
y = 2
Now that we know x = 2 and y = 2, then the intersection point of (x, y) must be (2, 2).
I hope this helps! Sorry if my English didn't really help with giving a clearer explanation.

3x^2-11x-6=0
Answer:
x = -0.62 and x = 4.29
These values are approximations !
Step-by-step explanation:
You can not use Factoring to solve this equation. Perhaps you did not use the exact notation as in the original question?
Anyway, to solve it, you can still use the ABC formula.
3x²-11x-6=0
a = 3
b =-11
c = -6
x = [11 + √{121 -4(3 *-6)} ]/ 2*3
x = [11 + √{121 -4(-24)} ]/ 6
x = [11 + √{121 + 96} ]/ 6
x = [11 + √{217} ]/ 6
x = 4.29 This is an approximation !
x = [11 - √{121 -4(3 *-6)} ]/ 2*3
x = [11 - √{121 -4(-24)} ]/ 6
x = [11 - √{121 + 96} ]/ 6
x = [11 - √{217} ]/ 6
x = -0.62 This is an approximation !

Step-by-step explanation:
What you have here is fine as is, except that the "1/2" should be enclosed in parentheses:
A = (1/2)(b1 + b2)h.
Alternatively, write:
b1 + b2
A = ------------- * h

solve the system of simultaneos equations using substitution method. 2/x-3/x=1 equation one 1/x-2/y= 2. equation two
Answer:
First solve the first one
2/x -3/x = 1
Multiply through by x
2/x×x -3/x×x = x
You will get
2 - 3 = x
x = - 1
Substitute x into the second Equation
1/x - 2/y = 2
x = 1
1/1 -2/y = 2
-2/y = 2-1
-2/y = 1
y = -2
Therefore x = - 1 and y = - 2
Hope this helps.
