Given table:
color ----- Frequency
Red ------ 14
Green ----- 19
Blue -------- 21
Yellow ----- 16
Number of process repeated (trials) = 70 times
Probability (event) = number of times the event occurs / total number of trials
From the table we can see that the number of times she pick the blue marble is 21
Probability of picking a blue marble on next try = 
= 
Steps:
1.Change x-y=9 into slope-intercept form.
Subtract x on both sides
-y=-x + 9
Divide everything by -1
Y= x-9
2. Now substitute the y in 5x + 4y=0 for x-9
5x + 4(x-9)= 0
5x + 4x-36=0
3. Now combine like terms
9x-36=0
4. Add 36 on both sides
9x= 36
5. Divide each side by 9
6. X= 4
7. Now substitute the x in x-y=9 for 4
4-y=9
8. Subtract 4 on both sides
-y= 5
9. Divide everything by -1
10. Y= -5
11. Your answer is x= 4 and Y= -5 or (4,-5)
Answer:
Step-by-step explanation:
5x5=25 so if u do 2x = it'll be 2x12=24 so thats the closetest thing u could do or i know hope it helps
Answer: (x+10) to the seccond power
Step-by-step explanation: 1
Use the sum-product pattern
x^{2}+{\color{#c92786}{20x}}+100
x^{2}+{\color{#c92786}{10x}}+{\color{#c92786}{10x}}+100
2
Common factor from the two pairs
x^{2}+10x+10x+100
x(x+10)+10(x+10)
3
Rewrite in factored form
x(x+10)+10(x+10)
(x+10)(x+10)
4
Combine to a square
