A = 28.356 ≈ 28.4
Here, we use law of sines, which says that sina / A = sinb / B. We know that b = 130 degrees, B = 10cm, and A = 6.2cm. Using algebra, we solve sina / 6.2 = sin130 / 10 to get a final answer.
Answer:
5x - 2y = -10 (B.) This should be right so if its not let me know I am stumped on what else it would be
Step-by-step explanation:
Parallelism: Same slope but different y-intercept
1 - Get into slope formula
5x - 2y = 7
<u>- 5x -5x </u>
-2y = -5x + 7
-2y/-2 = -5x/-2 +7/-2
y = (5/2)x - 7/2
2 - Plug x and y from (0, 5) into y = mx + b however note the - 7/2 is extranneous and wont be used for b
y = (5/2)x + b
5 = (5/2)0 + b
5 = 0 + b
5 = b
Therefore
y = 5/2x + 5 is your slope formula.
Now to get x to the other side.
3 - Get it back to standard form.
y = 5/2x + 5
- 5/2x -5/2x
- 5/2x + y = 5
(Multiply 2 into everything to get rid of the fraction)
-5x + 2y = 10
Answer:
7 ( x + 3 )
Step-by-step explanation:
Use order of operations to multiply first.
3+2x2 +7 x + 14
3+4 +7 x + 14
Now group like terms.
3+ 7x + 4 + 14
Add like terms
7x + 21
Find the two multiples of 21.
7x + 7 x 3
Now factor out the 7.
7( x + 3 )
Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) x = 5
You can get this with a calculator if you need by using the log function.
x = 5
b) x = 4
According to the product rule of exponents: 
So, x + 11 = 15 --> x = 4
That process is called "interpolation".
