Answer:
x = 1 1/4
Step-by-step explanation:
sqrt( 7x+2) = sqrt(3x+7)
Square each side
(sqrt( 7x+2))^2 = (sqrt(3x+7))^2
7x+2 = 3x+7
Subtract 3x from each side
7x-3x +2 = 3x+7-3x
4x+2 = 7
Subtract 2 from each side
4x+2-2 = 7-2
4x = 5
Divide by 4
4x/4 = 5/4
x = 1 1/4
Check for extraneous solution
sqrt( 7*5/4+2) = sqrt(3*5/4+7)
sqrt( 35/4 + 8/4) = sqrt(15/4+28/4)
sqrt( 43/4) = sqrt(43/4)
Solution is valid
The standard form:
The slope-intercept form:
m - slope
b - y-intercept
We have m = 3 and b = -5.
Substitute:
subtract 3x from both sides
change the signs
Answer:
Dante most likely asked the students if they should change the school mascot. This is a statistical question because the question can be answered by data that varies.
Step-by-step explanation:
You can see that the results for this question are either "yes" or "no". This means that Dante asked a question with a yes or no answer related to changing the mascot. This question was probably something along the lines of whether or not the mascot should be changed.
The definition of a statistical question is "a question that should have different answers". Therefore, this is a statistical question because the answers will be different from student to student.
Hope this helps!
Note that when x=0, y=-6, so d cannot be right. Note that 2 and -1.5 are solutions. The only answer choice that has both as zeroes is a.
