Step-by-step explanation:
We are to multiply;
× 
We first multiply 2 × 5 to get 10
Then multiply 3 × 7 to get 21
Finally divide 10 ÷ 21 to get 
Answer:
16/3
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given
C = 2πr ( isolate r by dividing both sides by 2π )
= r → D
Step-by-step explanation:
The factorisation of 49b^2 - 81 is (7b - 9)(7b + 9). This is because 49 and 81 are the squares of 7 and 9 respectively, so these must be multiplied together. b^2 is b x b. Finally, it must be -9 and +9 to make -81, because when the signs are the same the result is a positive number
Answer:
The equation of line in slope-intercept form is:

Step-by-step explanation:
Given the two points
slope between (0, -4) and (3, 2)




We know that the y-intercept can be determined by setting x=0, and solving for y.
From the graph, it is clear that
at x=0, y=-4
Thus, the value of y-intercept (b) = -4
We also know that the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
substituting m=2 and b=-4 in the intercept form


Thus, the equation of line in slope-intercept form is:
