Answer:
(10^11)/3
10^6 x 10^5 = 10^11
8/5 x 5/24 = 1/3
so multiply 10^11 and 1/3 together
<span>-3|15 - s| + 2s^3 when s = -3 is
</span>-3|15 - (-3)| + 2(-3)^3 = <span>-3|15 + 3| + 2(-27) = </span><span>-3|18| + (-54) = -3(18) - 54 = -54 - 54 = -108</span>
2x + 5y = 34
x+2y = 14
Multiply the second equation by two to create like terms for one variable.
2(x+2y = 14)
2x + 4y = 28
2x + 5y = 34
2x + 4y = 28 -- Subtract.
y = 34.28 = 6
Solve for x
x + 2(6) = 14
x + 12 = 14
x = 2
Check:
2 + 2(6) = 14
2 + 12 = 14
14 = 14
Answer:
X = 2
Y = 6
To find the markup, substract the price at which the car was bought from the price at which the car was sold:
To find the markup as a percentage from the original price, set 20,480 to be equal to 100%. If <em>x%</em> represents 6328, then:
To the nearest tenth, 30.898... = 30.9.
Therefore, the markup is equal to 30.9%.
Answer:
The perpendicular line would be y = -1/2x
Step-by-step explanation:
Perpendicular lines have opposite and reciprocal slopes. This means that we take the original slope (2) and negate it (-2). Now that we have the negated version, we need to flip it (-1/2).
With the slope of our new equation decided, we simply need to plug it along with the point into point-slope base form and then solve for y.
y - y1 = m(x - x1)
y + 4 = -1/2(x - 8)
y + 4 = -1/2x + 4
y = -1/2x
