Answer:
X=3
C=12
Step-by-step explanation:
(2x+6)=c
2x+6
x=2/6
x=3
2x3+6=c
c=12
It can be deduced that the population proportion formulated shows that the proportion is 3/5.
<h3>How to calculate the population proportion</h3>
Your information is incomplete as the table isn't given. Therefore, an overview will be given. It should be noted that a population proportion simply means a fraction of the population that has a particular characteristic.
In this case, let's assume that the population is 2000 and the most preferred menu item is chosen by 1200 people. Therefore, the <em>population</em> proportion of the most preferred menu item will be:
= 1200/2000
= 3/5.

Answer:
x = -5
Step-by-step explanation:
To find the equation of a line, use the formula y = mx + b, where m is the slope of the line and b is the y intercept.
To find the slope, use your ordered pairs: m = (y2 - y1)/(x2 - x1). Substituting in your values, m = (8-6)/(-5 - -5), or m = 2/0. Since you cannot divide by 0, the slope is undefined; you have a vertical line.
If you plot the points on a graph, (-5, 6) and (-5, 8) both pass through -5 on the x axis. Since this is a vertical line, it will never cross the y axis, so you will not have a y intercept.
Your equation is x = -5.
Answer:
gradient = -5
Step-by-step explanation:
A line passes (x1, y1) and (x2, y2) has the gradient (slope) which is calculated by:
gradient = (y2-y1)/(x2-x1)
As shown in picture, this blue line passes (-1, 0) and (0, -5)
=> gradient = (-5 - 0)/(0 - -1) = -5/1 = -5

Answer:
x=16
y=23
Step-by-step explanation:
angle (4x+4) and angle (7x-44) are alternate exterior angles which are equal, so we can set up an equation like this to find x:
4x+4=7x−44
calculate it then you'll get x=16
for the next one I'm not really sure how to explain since they are not labeled but,.. since we have the measure 39 we can figure out by using the pairs 'interior angles on the same side of a transversal' and 'vertical angles' that it's equal to 141, so to find y we use the equation
8y-43=141
calculate it and you'll get y=23
