Answer:
x = 2
y = 2
Step-by-step explanation:
Given that:
y=7x- 12 -------- eq1
-3x+4y=2 ------ eq2
eq1 can be written as:
7x - y = 12
Multiplying this equation by 4 we get:
28x - 4y = 48 --------- eq3
Adding eq2 and eq3 we get:
28x - 3x = 48+ 2
25x = 50
x = 2
Now put this equation in eq1
y = 7(2) - 12
y = 14 - 12
y = 2
i hope it will help you!
Answer:
339.292006π = 339.29π to 2 dp
Step-by-step explanation:
108 / 57.2957796 = 1.88495559 1.88495559×180°/π = 107.99999988° and 1.88495559×180° = 339.292006 π
Answer: i think method of least squares (d.)
Step-by-step explanation: i’m pretty sure this is correct because mean is good for unimodal, unskewed histograms, median is good for unimodal asymmetrical histograms, and mode is good for bimodal histograms. i’m not sure tho bcs i learned this in statistics.

Answer:
y = 5 sin (2x) + 4
Step-by-step explanation:
this is sines function,
the amplitude is [9 - (-1)]/2 = 10/2 = 5
the period is 2πx/π = 2x
the x-axis of actual function is at y = 4
so, the function is :
y = 5 sin (2x) + 4
