Answer:
The equation is y-a= b(x-b)
Step-by-step explanation:
I use bold for the slope so you can differentiate the slope term b from the y coordinate value b.
The equation of a line passing through a specific point and having a specific slope can be obtained using the point slope form of a line :
y-y1=m(x-x1) where m is the slope and (x1,y1) is your specific point.
So replacing your values, the point (x1,y1) =(a,b) and m=b, in this equation we havE:
y-a= b(x-b)
That can be expressed in point slope form and explicit for as.
y = b(x-b) + a = bx -bb +a =
y= bx + (a -bb)
The postal service delivered:
7.14 × 1010 pieces of mail in December
3.21 × 1010 pieces of mail in January
Total number of mail delivered is;
(7.14 + 3.21) × 1010
= 10.35 × 1010
= 1.035 × 10100 (in one decimal point form)
Answer:
The correct answer for this problem is
d) 1.035 x 10^11
Step-by-step explanation:
I know this because I just did the test
The hummingbird will take 1 minute 13 seconds.
Let the time that will be taken by the hummingbird be represented by x
Note that 1 minute = 60 seconds
Based on the information given, the equation that'll be used in the question will be:
45/55 = 60/x
Cross multiply
(45 × x) = (60 × 55)
45x = 3300
x = 3300/45
x = 73.33 seconds
x = 1 minute 13 seconds
The hummingbird will take 1 minute 13 seconds.

Answer:
1 2/9 minutes
Step-by-step explanation:
55 mph
55 / 60 = 11/12
11/12 of a mile = 1 minute
45 mph
45 / 60 = 3/4
3/4 of a mile = 1 minute
11/12 divided by 3/4
11/12 * 4/3
We can cross-cancel
11/3 * 1/3 = 11/9 = 1 2/9
It takes 1 2/9 minutes for the hummingbird to cross the lake
Hope this helps!

A) 10°
B) 11°
C) 20°
D) 21°
2. A right angle is shown divided in two parts. The measure of the angle of one part is 30 degrees and the measure of the other part is 5x plus 15 degrees. What is the value of x?
A) 3
B) 9
C) 12
D) 15
1) 10x+70 = 180
10x = 180-70
10x = 110
x =11
2) 5x+15+30 =90
5x = 90-45
x = 45/5
x = 9
The fraction of the kittens that are not white is 3/4.
Fractions are non-integers. Fractions are made up of numerators and denominators. An example of fractions is 1/2. 1 is the numerator and 2 is denominator.
Number of kittens that are not white = number of non-white kittens / total number of kittens
(8 - 2) / 8 = 6/8 = 3/4.
