Answer:
Solution → (3, -1)
Step-by-step explanation:
We ave to identify the graph representing the system of lines first.
y = 
Y-intercept of the line = -3
y = -2x + 5
y-intercept of the line = 5
From the given graphs 3rd (extreme right) graph is representing the system of equations.
Solution of the system of equations will be the point of intersection of these lines.
Solution of the system → (3, -1)
Answer:
Jersey cost $8 and pair of shorts $5
Step-by-step explanation:
There are several ways to solve this, but I will find the solution using the system of equations.
Let's mark price of jersey with x, and price of pair of shorts with y. That means:
12x + 12y = 156
4x + 6y = 62
Now, we can multiply the second equation with -2 to cancel out y:
12x + 12y = 156
-8x - 12y = -124
That only leaves us with:
12x - 8x = 156 - 124
4x = 32
x = $8
Now we plug the value for x into any equation to find y:
4x + 6y = 62
32 + 6y = 62
6y = 30
y = $5
Answer:
Step-by-step explanation:
isosceles trapezoid = congruent sides in pairs and the same for the angles
<h2><u><em>
angle 1 = 32°</em></u></h2><h2><u><em>
angles 2 & 3 = 148°</em></u></h2>
the sum of the interior angles is 360°
so angle 1 = 32°
angles 2 and 3
(360 - 32 - 32) :2 = 148°
check
32 + 32 + 148 + 148 = 360°
the answer is good
Answer:
1. 2.9
2. 51 inches
3. (if you can send a picture of the question, I can tell you an answer.
Step-by-step explanation:
for number 1:
You have to add the scores on the left and divide it by the total. What I did was multiply each number on the right with it's pair and added it up. I got 111. Afterwards, I totalled the number of students (I got 38) and divided the scores by the number of students to get 2.9.
for number 2:
You do the same thing as number one but instead of multiplying pairs, you add the heights. I got 255 and then divided it by 5 total heights. I got 51 inches.
for number 3: I didn't get the graph to tell you the answer but I can tell you what everything means.
Symmetric means that both sides of the graph are equal and if you fold the graph in half horizontally, you should get the same shape.
Gaps are where you see blanks in the graph where the data gets cut off and then has stats again.
Cluster is when a huge amount of data is gathered in one area.
Peak is where the data (x-axis) reaches it's highest point (highest y-axis point).
