Answer:
16
Step-by-step explanation:
The two angle created by the bisector have equal measures, so ...
m∠ABD = m∠DBC
2y = 5y -12
0 = 3y -12
0 = y -4
4 = y
2y = 2·4 = 8
m∠ABC = 2×m∠ABD = 2×8
m∠ABC = 16
_____
We presume the angle measures are in degrees, though that is not specified by the problem given here. These numbers could all be radians, but 16 radians is more than a couple of times around the circle.
A. 14 years old
B. 13 years old
C. 12 years old
D. 11 years old
Answer:
The correct option is C.
Step-by-step explanation:
The graph below shows a scatter plot and the line of best fit relating the ages of children and the total number of times they have visited the doctor.
If a line passes through two points then the equation of line is
From the given graph it is clear that the line of best fit passes through the points (0,0) and (3,10). So, the equation of best fit line is
.... (1)
The equation of best fit line is . Where, x is age in year and y shows the total number of visits to the doctor.
We need to estimate the age of a child who has visited the doctor 40 times.
Substitute y=40 in equation (1), to find the value of x.
Multiply both sides by 3.
Divide both sides by 10.
The value of x is 12. It means the age of a child who has visited the doctor 40 times is 12.
Therefore the correct option is C.
The kid is around 12 years old that visits the doctor 40 times
Answer:
y-intercept = 1/3
Step-by-step explanation:
c = y-intercept
y-intercept= 1/3
Hello! :)
To find the y-intercept, substitute 0 for x-intercept then you will get the y-intercept.
(0,1/3) y-intercept

The factorized form of the expression using the difference of two square is 2(x+3)(x-3)
Given the following function expressed as 2x^2 - 18
Factor out the GCF
2(x^2 - 9)
This can be written as
2(x^2 - 3^2)
According to the difference of two square, a^2 - b^2 = (a+b)(a-b)
Simplify
2(x^2-3^2) = 2(x+3)(x-3)
This given the factorized expression of 2x^2- 18

Hi Brainiac
2x² - 18
First you need to factor out the common term which is 2
2(x²-9)
Now factor x²-9
2(x+3)(x-3)
