If you would like to solve the system of linear equations, you can do this using the following steps:
2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x
The correct result would be: y = 2x + 1, <span>2x + y = -7.</span>
Answer:
<h2>The equivalent to sin 60 is cos 30</h2>
Step-by-step explanation:
we can obtain our answer either from calculator
or from four figure table
from calculator punching sine 60 will display 0.8660
likewise cosine 30 will display 0.8660
Hence both trigonometric values are equivalent
Y = mx + b
slope(m) = -8
(-11,7)....x = -11 and y = 7
now we sub into the formula and find b, the y int
7 = -8(-11) + b
7 = 88 + b
7 - 88 = b
- 81 = b
so ur equation is : y = -8x - 81 or 8x + y = -81 depending on what form u need it in
