Answer:
x=5 or x=5, x=-5
Step-by-step explanation:
If the question is then you take the square root of both sides. because 25=5*5=.
When you simplify you get x=5
So x=-5, =5.
Answer:
C ≤ 2
Step-by-step explanation:
Given that :
Clayton is at most 2 meters above sea level ;
Let Clayton = C
Clayton's distance can be represented by the inequality :
2 meters above sea level is positive, +2
At most 2 meters above sea level means, Clayton could be anywhere between + 2 metwrs but not more than 2 meters
Hence, Clayton's distance can be represented by the inequality :
C ≤ 2
Answer:
B. The car's age is the explanatory variable
Step-by-step explanation:
The graph shows a negative linear relationship between car's age and car's value because, as as one variable increases, the other decreases.
Also, data points are close to each other along the line of best fits, therefore, the correlation coefficient would be close to -1, showing a strong negative relationship.
An explanation variable is one that isn't affected or dependent on another variable. In this case, the car's age is the explanatory variable and not the car's value. The car's value is dependent on the car's age, therefore, the car's age is the explanatory variable.
The statement in option B is FALSE.
Answer:
Step-by-step explanation:
<u><em>Girls for English:</em></u>
20 + English + 12 = 36
English + 32 = 36
English = 36-32
English = 4 (For girls)
<u><em>Total for Science:</em></u>
12+7 = 19
<u><em>Total for English:</em></u>
25 + English + 19 = 70
English + 44 = 70
English = 70-44
English = 26 pupils
