Answer:
,
Step-by-step explanation:
you use the quadratic equation: (-b ± ) ÷ 2a
in this case, a = 5, b = 5, c = 8
inside the radical will be -135, hence using 135i where 'i' equals -1
The P right there you put = -3/7 after it
Answer:
answer is 13/50
Step-by-step explanation:
0.260/1 × 1000/1000 = 260 /1000
26/100
so final answer is 13/50
Answer:
Explanation: ... To find the product of a binomial and a trinomial, multiply out the brackets: ... Simplify. \[{\left(x - 1\right)\left({x}^{2} - 2x + 1\right)} = {x}^{3} - 3{x}^{2} + 3x - 1\] ... \begin{align*} (-2y^{2} - 4y + 11)(5y - 12) & = -10y^{3} - 20y^{2} + 55y + 24y^{2} + 48y ...
Answer:
x = -5 and y = 2
Step-by-step explanation:
You want to start by writing these two equations:
x + y = -3
and
x - y = -7
Then, you want to add the solutions to these two equations, like so:
-3 + -7 = -10
Then, to find the x value, because x > y, divide the answer by two:
-10/2 = -5
So, the x value is -5.
With this information, you can figure out that the y value is 2.
Check the answer:
-5 + 2 = -3
-5 - 2 = -7
Hope this helped
