Answer:
2x to the second power +x−10
Step-by-step explanation:
Let's simplify step-by-step.
5x+x2−4−(4x−x2+6)
Distribute the Negative Sign:
=5x+x2−4+−1(4x−x2+6)
=5x+x2+−4+−1(4x)+−1(−x2)+(−1)(6)
=5x+x2+−4+−4x+x2+−6
Combine Like Terms:
=5x+x2+−4+−4x+x2+−6
=(x2+x2)+(5x+−4x)+(−4+−6)
=2x2+x+−10

Answer:
see explanation
Step-by-step explanation:
Since KL = KM then the triangle is isosceles and the 2 base angles are congruent, that is
∠KLM = ∠KML, thus
y - 9 = x + 4 (add 9 from both sides )
y = x + 13 → (1)
The sum of the 3 angles in the triangle = 180°, thus
x + 4 + y - 9 + x + y + 3 = 180
2x + 2y - 2 = 180 ( add 2 to both sides )
2x + 2y = 182 → (2)
Substitute y = x + 13 into (2)
2x + 2(x + 13) = 182 ← distribute and simplify left side
2x + 2x + 26 = 182
4x + 26 = 182 ( subtract 26 from both sides )
4x = 156 ( divide both sides by 4 )
x = 39
Substitute x = 39 into (1)
y = 39 + 13 = 52
Hence
∠K = x + y + 3 = 39 + 52 + 3 = 94°
Answer:
(-2,1) and (3, -4)
Step-by-step explanation:
(-2,1) and (3, -4) this is where the lines intersect, hence these are the solution. :) have a great night!
Answer:
-2,4/3
Step-by-step explanation:
ax²+bx+c=0
Okay so slope intercept form is y=mx+b
Where b is the y intercept, m is the slope and x is the changing variable. So in this case let x represent the number of hours and m equal the cost per hour $2. That leaves $5 as the y intercept. So your equation is y=2x+5
