What is the rate of change of y with respect to x for 25x - 4y = 50 ?
Answer:
25/4Step-by-step explanation:
The change of y with respect to x is known as the slope of the line. The standard form of the equation is y = mx+c where m is the slope.
Given the equation 25x - 4y = 50, we need to make y the subject of the formula before we get the slope as shown;
25x - 4y = 50
-4y = -25x+50
Divide through b y -4
-4y/-4 = -25x/-4 + 50/-4
y = 25/4 x - 25/2
Comparing with y = mx+c
mx = 25/4 x
m = 25/4
Hence the rate of change of y with respect to x is 25/4
The rate of change of y with respect of x for the given equation is [tex]\frac{25}{4}[/tex].
Given the equation:
[tex]25x - 4y = 50[/tex]
The rate of change = the slope of the line
To determine the slope of 25x - 4y = 50, rewrite the equation in slope-intercept form. i.e. [tex]y = mx + b[/tex]Where, slope = mThus,[tex]25x - 4y = 50[/tex]
Add 25x to both sides of the equation[tex]25x -25x - 4y = - 25x + 50\\\\-4y = - 25x + 50[/tex]
Divide both sides by -4[tex]\frac{-4y}{-4} = \frac{-25x}{-4}+ \frac{50}{-4}\\\\y = \frac{25}{4}x - \frac{25}{2}[/tex]
Therefore, the rate of change of y with respect of x for the given equation is [tex]\frac{25}{4}[/tex].

What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture:
As we know, triangle is a polygon with three sides and three interior angles.
From the definition of the triangle, The triangle's interior angles add up to 180°
m∠MKL + m∠MLK + m∠KML = 180
Also, the sum of the two interior angles is equal to the exterior angle.
m∠KML + m∠MLK = m∠JKM
Thus, the statement regarding the diagram "m∠KML + m∠MLK = m∠JKM" is true option (B) m∠KML + m∠MLK = m∠JKM is correct.

Answer:
Slope: [tex]-\frac{3}{4}[/tex]
Y intercept: 7
Equation: [tex]y=-\frac{3}{4}x+7[/tex]
Step-by-step explanation:
The slope is found by doing the equation [tex]\frac{rise}{run}[/tex]. When looking at the first two points, it's shown that the rise (difference between the two y values) is -3 (since it decreased by 3) and the run (difference between the two x values) is 4 (since it increased by 4).
This gives us a slope of [tex]-\frac{3}{4}[/tex].
The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.
The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!
The graph shows the membership of a student group: x represents the number of years since the group was formed and y represents the number of members.
The equation is y = 14x + 10.
Which is true regarding the slope?
Membership grows by 14 each year.
The group was formed with 14 members.
Membership is recorded every 14 years.
Answer:
we conclude that Membership grows by 14 each year.
Step-by-step explanation:
Given the equation
[tex]y=14x+10[/tex]
Comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here, m is the slope and b is the y-intercept.
From the equation, we can determine the slope
[tex]y=14x+10[/tex]
[tex]m=14[/tex] ∵ [tex]y=mx+b[/tex]
Hence, the slope is m=16.
We know that the slope is referred to as the 'rate of change'.
For example, if you have a part-time job at a store. You save for her tour at a rate of $20 every week. It means, your rate of change will be $20 per week.
So given the equation
[tex]y=14x+10[/tex]
m = rate of change = slope = 24
The slope is basically a vertical change divided by the horizontal change.
Therefore, we conclude that Membership grows by 14 each year.

A line has a slope of 3/2 and has a x-intercept of 2 . What is the y-intercept of the line?
Answer:
- 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute the x- intercept (2, 0 ) into the partial equation
0 = 3 + c ⇒ c = 0 - 3 = - 3 ← y- intercept
Every 2.5 hours, a machine produces 150 baskets.

60 baskets per hour
2.5 baskets per hour
2.5 baskets per hour
25 baskets per hour
25 baskets per hour
16.6 baskets per hour
Answer:
60
Step-by-step explanation:
We use unit rate function,
Let h be hours
Let b be baskets
2.5h = 150b
We divide both sides by 2.5
2.5h/2.5 = 150b/2.5
Which will give us
h = 60

Answer:
Type: polynomial
degree: 3
leading coefficient: 8
Step-by-step explanation:
The given equation is: f(x) = -7x^2 + 8x^3 + 6 - 4x
To find the type, degree, and leading coefficient of the equation, the first thing we should do is rewrite the terms in decreasing order:
f(x) = 8x^3 - 7x^2 - 4x + 6
The term with the highest value is 8x^3. We can use this to determine the degree and the leading coefficient.
8 is the leading coefficient. The degree is 3.
To find the type of equation this is, we have to count how many terms there are. We can see that there are 4 terms in this equation, making this a polynomial.

Given that, Ms.Kirklan is baking muffins. Each batch of muffins use 3/4 of a pound of flour.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
We need to find the number of muffins she can bake with 5 pounds of flour
Now, 5 ÷ 3/4
= 5 ÷ 0.75
= 6.6
≈ 7

Forty of the staff of 85 teachers at a local intermediate school are certified in Cardio-Pulmonary Resuscitation (CPR). In 180 days of school, what would be the expected mean, variance and standard deviation?
Answer and Step-by-step explanation:
The computation is shown below;
Here we use the binomial distribution
p = 40 ÷ 85 = 0.47
q = 1 -0.47 = 0.53
n = 180
Now
mean [tex]\mu[/tex]
= np
= 180 × 0.47
= 84.6
The Variance is
= npq
= 180 × 0.47 × 0.53
= 44.84
And, Standard deviation
= √npq
= √44.84
= 6.69
