Plot the point (11, 7) on the coordinate plane.
Answer:
Step-by-step explanation:
When you're asked to plot a point on a coordinate plane just remember that the coordinate given is of the form [tex](x,y)[/tex].
So, first, we need to plot 11 on the [tex]x[/tex]-axis (the line going left to right, horizontal) then plot 7 on the [tex]y[/tex]-axis (the vertical line)
So we first go 11 units to the right along the [tex]x[/tex]-axis then go up 7 units along the [tex]y[/tex]-axis.
Hope this helped.

y = (x − 4)2 − 4
y = (x + 4)2 − 4
y = (x + 2)2 + 6
y = (x + 2)2 + 12
Answer:
Hi there!
The vertex form equation is y=a(x-d)^2+c where the vertex is (d, c).
The vertex is always the turning point when the y-values start to travel in the opposite direction from which they began traveling on the opposite side of the turning point. Therefore the point (4, -4) is the vertex.
y=a(x-4)^2-4
We can sub in a point on the graph in order to solve for the a-value. Let's use (6, 0), and sub that in for x and y.
0=a(6-4)^2-4
0=a(2)^2-4
4=4a
a=4/4
a=1
Therefore the equation is y=(x-4)^2-4

Write an equation in slope intercept form that contains the points (-6,3) and
(-2,1)..
Answer:
y= (-1/2)x+1
Step-by-step explanation:
The general equation of a line in the slope intercept form is y= mx+b, where
m = the slope, and b = y-intercept (where the line crosses the y-axis)
for points (x1 = -6, y1 = 3) and (x2 = -2, y2 = 1)
m= (y2-y1)/ (x2-x1) = (1 - 3)/ (-2 - -6) = -2 / 4 = -1/2
the equation is now y= (-1/2)x+b
substitute the x and y coordinates of any of the points in the equation
for point (-2, 1) we will have 1 = (-1/2)(-2)+b, so b=1
The equation in slope intercept form that contains the points (-6,3) and
(-2,1) is y = (-1/2)x+1

a boat traveled 14 miles per hour downstream. the trip upstream was at a speed of 10 miles per hour. what is the speed of the boat in still water? what is the speed of the current
Answer:
(im not sure what the first question is asking me)
Speed of the current is 2 miles per hour
Step-by-step explanation:
The reason the current is 2 miles per hour is because it when going down stream they were going 14 miles per hour, going upstream they went 10. The difference is 4mph. So if the current pushes you 2mph when going down stream and holds you 2 mph when going up, the constant speed is 12mph then you add and subtract 2 becuase of the two directions youre traveling. hence 10mph and 14mph.
Least to greatest 3%,00.8,2/50
Answer:
3% , 2/50 , 0.08
Step-by-step explanation:
I believe the easiest way to go about this is to convert all the numbers t0o decimals!
0.08 is already given, so we just need to figure out what 3% and 2/50 are in decimal form.
When converting percents to decimals, a good rule of thumb to remember is to divide the percent by 100.
3 ÷ 100 = 0.03
For fractions, simply divide the numerator by the denominator:
2 ÷ 50 = 0.04
Now we just order the numbers based on their value...
0.03, 0.04, 0.08
So the final answer should be:
3% , 2/50 , 0.08
Hope this helps :D

Answer:
Median. Explanation to each part below.
Step-by-step explanation:
a) Starting with calculating the mean, which is all the values added divided by the number of values (in this case he has 6 scores total).
[tex]mean/average=\frac{81+87+93+89+61+81}{6} =\frac{492}{6} = 82[/tex]
b) To find the median, arrange all the test scores in increasing order and find the middle/median value. We have 6 scores, so we will have 2 middle scores. If we had 7 scores, we would find only 1 score in the middle which would be the median. We will have to find the average of the two scores.
[tex]61,81,81,87,89,93[/tex]
The middle values will be 81 and 87 so find the average of those 2 scores.
[tex]Median: \frac{81+87}{2} =\frac{168}{2} =84[/tex]
c) The mode is the score which occurs the most. In this case, Jack has 2 scores that are 81, which is his mode.
d) The measure that would make his performance sound good would be the median. The mode and mean are below the score of 84 that he gets for the median. He would want to flaunt this measure to show he performs well.
