Answer:
y=10.4
Step-by-step explanation:
If you mean Y instead of x then the answer is 10.4
3.8+y=14.2
-3.8 -3.8
y=10.4
S10 = -150;
<span> the sum of next 10 terms = S20 - S10 => -550 = S20 + 150 => S20 = -700;
</span>S10 = -150 => 2a1 + 9r = -30;
S20 = -700 => 2a1 + 19r = -70;
Then 10r = -40 => r = -4 , and, 2a1 -36 = -30 => 2a1 = 6 => a1 = 3;
Step-by-step explanation:
For a moment let y = x^2 + 5
Then by the distributive property
(2x^2 + 4x - 3 ) P = . 2x^2p + 4xp - 3p
Again by the distributive
2x^2 p = 2x^2(x^2 - 2x +5) = 2x^4 - 4x^3 + 10x^2
4xp = 4x(x^2 + 5) = 4x^3 - 8X^2 +20x
-3p = -3(x^2 - 2x + 5) = -3x^2 + 6x -15
Taking everything together we get
(2x^2 + 4x -3 )(x^2-2x + 5) = (2x^4 -4x^3 +10X^2) + (4x^3 - 8x^2 + 20) + -3x^2 + 6x -15)(2X^2 + 4x - 3 )(x^2 -2x = 5) = 2x^4 + 26 - 15
Answer:
Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.
Step-by-step explanation:
to find the distance between two point A(-4, -2) and B(-7, -7) we use the following distance formula
x1=-4, x2=-7
y1=-2, y2=-7
so,
