Answer:
<h2>a = 3</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula

From the question the slope is - 3
To find the value of a we have

Divide both sides by - 3

We have the final answer as
<h3>a = 3</h3>
Hope this helps you
Answer:
Yi Xing invented the astronomical clock and introduced some new methods of interpolation in mathematics.
Step-by-step explanation:
Yi Xing was both an astronomer and a mathematician during the era. He invented the astronomical clock which was more accurate than the initial water and Sun's clock in use.
Furthermore, Yi Xing also discovered some new methods of interpolation in mathematics of which the meaning and interpretation became controversial. Interpolation is a method majorly in mathematics that can be used to estimate a value of a function from its discrete values. It involves first order differences and second order differences.
Also, Yi Xing was able to design a calendar in A.D. 727.
C is the answer. (X) can’t be repeated
Answer:
Gradient is 11/4 and y intercept -8
Step-by-step explanation:
11X -4Y =32
transfer 11x on other side
-4y = -11x +32
multiply all termsby -1 so that coefficient of y is positive
4Y = 11X -32
DIVIDE ALL TERMS BY 4
Y = (11/4)X -8
COMPARE THIS WITH Y=mX +C
GRADIENT m is 11/4 and Y intercept C is -8
Gradient is 11/4 and y intercept -8
Hey! So I’m pretty sure you multiply 56 and 2, then you swap the sides of the equation. Answer: X=112
