What is the solution to the system of equations graphed below?
y = x. 3
y=3x+1
y = x+3
y = 3x + 1
A. (0,1)
B. (1.4)
C. (1,3)
D. (0,3)
Help pls
Answers
Answer:
(1,4)
Step-by-step explanation:
Let y (upper eq) = y (lower eq)
x+3 = 3x+1
(transposing similar numbers)
3x-x = 3-1
2x = 2
then x = 1
substituting x in any of the equation, say
y = x+3
y = 1 +3
y = 4
therefore (1,4)
check again the lower equation
y = 3x + 1
y = 3(1) + 1
y = 4
therefore (1,4)

Answer:
AM=1 false
BM= ½ true
AM=½ false
BM= √3/2 false
AM= ✓3/2 true
BM=1 false
Step-by-step explanation:
Since the triangle is equilateral it means that all sides are of the same length. So AB=1, BC=1, AC=1
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= ½ true because BC=1 so BM (half)=0,5=½
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= √3/2 false because it's ½
AM= ✓3/2 true because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM=1 false because BM= ½
B is the midpoint of AC. AB=2x+4; BC=5x-11. Find X
Answers
Answer:
x=5
Step-by-step explanation:
AB and BC must be equal if B is a midpoint
Therefore
2x+4=5x-11
Simplify:
add 11 to both sides=
2x+15=5x
subtract 2x both sides:
3x=15
Divide
x=5
Answer:
x=5
Step-by-step explanation:
Since B is the midpoint you would need to form the equation like this:
[tex]2x+4=5x-11\\-2x+11 -2x+11\\15=3x\\x=5[/tex]

Answer:
Total Number of times Spun = 1200
Key sentence: "Pr(Red) is same as Pr(Yellow).
Pr(Green)= 0.2
0.2 = x/1200
x= 0.2 x 1200
x = 240.
It landed on green 240 times
Pr(Brown) =0.54
0.54 = y/1200
y= 1200 x 0.54
y= 648.
Now
To get the Number of times it landed on Red and Yellow
You simply subtract that of Green and Brown from 1200 and divide this result by 2(Since Red and Yellow are have equal occurrence).
1200 – (648 + 240)
= 312.
312/2 = 156.
So It landed on Red and Yellow 156 times each.
Step-by-step explanation:
Red ----- 156times
Green -----240times
Brown ----- 648times
Yellow -----156times

Coffee Tea Soda Energy drink

The picture graph below displays the results of the survey.
A graph titled Caffeinated Drinks has drink on the x-axis and relative frequency on the y-axis. Coffee, 0.8; tea, 0.75; Soda, 0.75; energy, 0.2. The coffee, tea, and soda pictures are large, and the energy drink picture is small.
Is this graph misleading?
No, because the pictures accurately represent the percentage of each type of drink.
No, because the height of each picture corresponds to the percentage of each type of drink.
Yes, because the height of each picture does not correspond to the percentage of each type of drink.
Yes, because the areas of the pictures do not accurately represent the proportions of each type of drink.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The correct option is B.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
From the given equation that is true are,
A. 63 x 103 = 63,000
If we multiply 63 and 103 the product will be 6,489. Since the two sides of the equation are not true, therefore, the given equation is false.
B. 63 x 10,000 = 630,000
If we multiply 63 and 10,000 the product will be 630,000. Since the two sides of the equation are true, therefore, the given equation is true.
C. 63 x 102 = 630
If we multiply 63 and 102 the product will be 6,426. Since the two sides of the equation are not true, therefore, the given equation is false.
D. 63 x 1,000 = 6,300
If we multiply 63 and 1,000 the product will be 63,000. Since the two sides of the equation are not true, therefore, the given equation is false.
E. 63 x 105 = 6,300,000
If we multiply 63 and 105 the product will be 6,615. Since the two sides of the equation are not true, therefore, the given equation is false.
Hence, the correct option is B.
