Answer:
11x + 12
Step-by-step explanation:
( 4x + 12 ) + 7x
Remove parentheses.
= 4x + 12 + 7x
Group like terms.
= 4x + 7x + 12
Add similar elements: 4x + 7x = 11x
= 11x + 12
Answer:
Step-by-step explanation:
The function
is a positive upwards opening parabola with the vertex at (0, 4), whereas
the function
is a positive rightwards opening parabola (sideways parabola) with the vertex at (4, 0). This means that answer to this is that g(y) is reflected over the x axis whereas f(x) is reflected over the y axis.
Answer: C. 12.5
Step-by-step explanation:
Given : A manufacturer of new light bulbs claims the average lifetime of its long-life bulb is more than 4000 hours.
Population mean : 
Sample size : n= 100
Sample mean : 
Standard deviation: 
The value of test-statistic is given by :-

Hence, the value of the test statistic for this problem is 12.5.
4x = 14y
y = 4/14(x)
y = 2/7(x) slope = 2/7
<span>-2x+7y=14
7y = 2x + 14
y = 2/7(x) + 2 slope = 2/7
parallel lines, slope is the same
both lines have slopes equal 2/7
