Answer:
Step-by-step explanation:
A.) x² + 1 = 2x − 3 Make the equation into ax² + bx + c = 0. Subtract 2x on both sides, and add 3 on both sides to set the equation equal to 0
x² + 1 - 2x + 3 = 2x - 2x - 3 + 3
x² - 2x + 4 = 0
a = 1
b = -2
c = 4 This is not the answer because b = 2 not -2, and c = -4 not 4
B.) x² - 2x − 1 = 3 Subtract 3 on both sides to set the equation = 0
x² - 2x - 4 = 0
a = 1
b = -2
c = -4 This is not the answer because b = 2 not -2
C. x² + 2x - 1 = 3 Subtract 3 on both sides to set the equation = 0
x² + 2x - 4 = 0
a = 1
b = 2
c = -4 This is your answer
D. x² + 2x - 1 = -3 Add 3 on both sides to set the equation = 0
x² + 2x + 2 = 0
a = 1
b = 2
c = 2 This is not the answer because c = -4 not 2
Hope this helps :)
2x + 2x + 124 + 124 = 360
4x + 248 = 360
2x = 360 - 248 = 112
x = 112/2 = 56
Express tan in terms of sin and cos
= sin ax cos bx / sin bx
Now I'm stuck! sorry
For what its worth Ive drawn the graph and the answer is a/b
Answer:
<h2>The answer is option D</h2>
Step-by-step explanation:
To find the equation of a line given the slope and a point we use the formula
<h3>
</h3>
where
m is the slope
( x1 , y1) is the point
From the question
slope = 0
The point is (- 2 , 7)
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h2>
</h2>
Hope this helps you
Answer:
The result in standard form is:
Step-by-step explanation:
Given the polynomials
subtracting 8t² + t from -5t+ 4t² – t.
Remove parenthese: (-a) = -a
i.e. - (8t² + t) = 8t² - t
so the expression becomes
grouping the like terms
Add similar elements: 4t² - 8t² = -4t²
Add similar elements: -5t - t - t = -7t
Therefore, the result in standard form is:
