Answer:
(fog)(x)=f(g(x))=2(3x+2)−1=6x+4−1=6x+3=3(2x+1)
A) No solutions, because the number under the square root symbol in the quadratic equation (b^2 - 4ac) is negative.
B) One solutions, because the number under the square root symbol in the quadratic equation (b^2 - 4ac) is equal to 0.
Answer:
(D)The distance between points A and B
Step-by-step explanation:
To copy a segment AB, the first thing is to identify the length of the segment which is the distance between points A and B. It is this distance that will be used to create a new segment at a given point not on the segment.
Midpoints have nothing to do with copying a segment.
<u>The correct option is D.</u>
Answer:
65 years old
Step-by-step explanation:
G . = grandma
d = grand daughter
g = 13d
g+1= 11(d+1) - - distributive property
g + 1 = 11d+11
subtract 1 from both sides
g = 11d+10
substitute g = 13d into equation
13d = 11d+10
subtract 11d from both sides
2d = 10
divide both sides by 2
d = 5. the grandaughter is 5, and the grandma is currently 13 * the granddaughters age. 5*13 = 65. hope it helped
