Find the slope of the line.
Y=5/3x
Answer:
[tex] \frac{5}{3} [/tex]
~ See attatchment
Step-by-step explanation:
I'm unsure what you want me to do here, so I drew a graph (using Desmos) and the slope.
The slope is given, 5/3. The slope-intercept equation is usually y = mx + b -- m being the slope and b being the y-intercept.
Hi!
Let's check if the equation that we're going to work with is in slope-intercept form.
Remember, the slope-intercept formula is:
[tex]\diamondsuit~~~\boldsymbol{y=mx+b}[/tex]
Where:
m -> Slopeb -> Y-interceptDetails:
[tex]\boxed{\\\begin{minipage} {8cm}\sf{Slope = coefficient \ of \ x, \ or \ the \ number \ before \ x.}\\\sf{Y-intercept = \ a \ number \ added \ to \ or \ subtracted \ from \ the \ slope.} \end{minipage}}[/tex]
Therefore:
[tex]\stackrel{\heartsuit}{\boxed{\boxed{\textsc{Slope:}\quad\boldsymbol{\displaystyle\frac{5}{3}}}}}[/tex]

proceeds from the sale were $2,605. A
total of 89 items were sold, some at $20
each and the rest at $35 each.
Answer:
34 sold for $20
55 sold for $35
Step-by-step explanation:
20x+35y=2605
y=(98-x)
20x+35(89-x)=2605
Solve for x
20x+3115-35x=2605

Step-by-step explanation:
I believe you meant 74.94*10^3. The ^ indicates exponentiation. 10^3 is equivalent to 1000; Multiplying 74.94 by 1000; we get 74940.
A rectangular gift box has dimensions that can be represented as shown in the figure. The volume of the box is 56w cubic inches. Which of the following is not a dimension of the box?
The dimension of the box is 12 by 7 by 8
How to calculate the volme of a boxThe volume of the box = lwh
Given the following
l = w
w = w - 5
h = w - 4
Hence;
w(w-5)(w-4) = 56w
Expand to have
(w^2-5w)(w-4) = 56w
w^3 - 4w^2 - 5w^2 + 20w = 56w
w^3 -9w^2 - 36w = 0
Factorize to get the value of w;
w(w^2-9w-36)=0
w^2 - 12w + 3w - 36 = 0
w(w-12) + 3(w-12)= 0
w = -3 and 12
Hence the dimension of the box is 12 by 7 by 8

can someone find the slope intercept equation thanks and can you explain it
Answer:
the slope is -2x
Step-by-step explanation:
Its negative because the line is going towards the negatives, and 2 because the slope is rise over run. the line is going up 2 and over 1, which means 2/1, which simplifies to 2
Answer:
-2x -2
Step-by-step explanation:
The slope is negative because it is going down instead of up
y intercept is -2
Use rise over run
Rise is y x is run select 2 points and check rise/run
Slope= - x -(y)
-2
Given the functions f(x), g(x), and h(x) shown below; list the functions from greatest to least by average rate of
change over the intervall
Answer:
f(x) > h(x) > g(x)
Step-by-step explanation:
For the average rate of change of a function between x = a and x = b,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
From the table given,
Average rate of change of function 'f' between x = 1 and x = 3,
Average rate of change = [tex]\frac{f(3)-f(1)}{3-1}[/tex]
= [tex]\frac{15-7}{3-1}[/tex]
= 4
For the function 'g',
g(x) = 2x² - 18x
Average rate of change = [tex]\frac{g(3)-g(1)}{3-1}[/tex]
g(3) = 2(3)²- 18(3)
= 18 - 54
= -36
g(1) = 2(1)² - 18(1)
= 2 - 18
= -16
Therefore average rate of change = [tex]\frac{-36+16}{3-1}[/tex]
= -10
From the graph attached,
Average rate of change of the graph between x = 1 and x = 3,
Average rate of change = [tex]\frac{h(3)-h(1)}{3-1}[/tex]
h(3) = 7.5 [Although the graph is not clear]
h(1) = 2
Average rate of change = [tex]\frac{7.5-2}{3-1}[/tex]
= 2.75
Therefore, order of rate of change (from greatest to the least) for the given functions will be,
f(x) > h(x) > g(x)

6. Select all the inequalities that have the same solutions as -4x < 20.
A. -x > 5
B. 4x > -20
C. $4x
D. $x
E. x > 5
F. x > -5
(From Unit 6, Lesson 13.)
Answer:
F and B (as far as I can see).
Step-by-step explanation:
First, let's simplify the equation. You can easily do this by dividing by -4.
-4x < 20
/-4 /-4
x > -5
REMEMBER- Whenever dividing or multiplying a negative number with inequalities, the sign flips!!
On A, we can see that it has a negative symbol, but if we were to divide that, the sign would flip, making -5 greater than x. That's not what we want.
On B, the 20 is negative instead of the 4. Does this change anything?
4x > -20
/4 /4
x > -5
Nope! It still simplifies to what we had at the beginning so it works!
C and D are slightly confusing me because, well, I don't really see how it's relevant to anything so... It doesn't even have a inequality symbol so I don't know lol.
E is wrong because we need the 5 to be positive.
F is obviously right compared to our first answer.
Answer: F, b, a
Step-by-step explanation:
A sine function has the following key features: Period = 4pi Amplitude = 2 Midline: y = 3 y-intercept: (0, 3) The function is a reflection of its parent function over the x-axis.
did I get this right?
The sine function is:
f(x) = -2*sin(x/2) + 3.
So you got it almost correctly, you only forgot to apply the reflection.
How to get the sine function?We start with the general sine function:
[tex]a*g(w*x + p) +m[/tex]
where g(x) = sin(x)
a is the amplitude, which we know is equal to 2.w depends on the period.M is the midline, which we know is equal to 3.p is the phase shift, because the y-intercept is (0, 3) we know that:f(0) = 2*sin(w*0 + p) + 3 = 3
= 2*sin(p) + 3 = 3
Then we must have p = 0, so there is no phase shift.
We also know that we have a reflection over the x-axis of the parent sine function, we would actually have:
f(x) = 2*-sin(wx) + 3
Finally, to get the value of k we know that the period of the general sine function is 2*pi, while here is 4*pi, then we must have w = 1/2 to get the correspondent correction, so the function is:
f(x) = -2*sin(x/2) + 3.
This is almost the same thing that you got in the graph, where you only forgot to apply the reflection over the x-axis of the parent function.
