Answer:
k = 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
note the line crosses the y-axis at - 3 ⇒ c = - 3
y = 2x - 3 ← is the equation of the line
Since (k, 10) lies on the line then the coordinates of the point make the equation true.
substitute (k, 10) into the equation and solve for k
10 = 2k - 3 ( add 3 to both sides )
13 = 2k ( divide both sides by 2 ), hence
k = 
Given:
The expression is

To find:
The value of given expression.
Solution:
We have,

BODMAS : Bracket, Order, Division, Multiplication, Addition, and Subtraction.
Using BODMAS, first we need to perform division in the given expression.



Now, apply addition.


Now, apply subtraction.

Therefore, the value of given expression is 1.
Answer:
- She traveled 45 miles in 1 hour
- She traveled 270 miles in 6 hours
- She traveled 360 miles in 8 hours
Step-by-step explanation:
If Mrs. Anglin traveled at a speed of 90 miles in 2 hours, it means that her speed per hour is:
= 90/2
= 45 mph
If she is travelling at 45mph then in 1 hoour she would have traveled 45 miles.
In 6 hours she would have traveled:
= 45 * 6
= 270 miles
In 8 hours she would have traveled:
= 45 * 8
= 360 miles
