ABC is similar to JKL. Notice how C is the right angle (90 degrees) as shown by the square angle marker. Angle L matches up with angle C. They are the last letters of ABC and JKL
So angle L = 90 degrees as well
Answer:
<em>x = 1 + ( √ 10 )/ 2, or x = 1 - ( √ 10 )/ 2; Option A</em>
Step-by-step explanation:
See steps below;
I would prefer answering this question by completing the square, rather than applying a quadratic formula;
3x^2 - 6x - 12 = 0, ⇒ Add 12 to either side,
3x^2 - 6x = 12, ⇒ Divide either side by 3,
x^2 - 2x = 4, ⇒ Write the equation in the form x^2 + 2ax + a^2 = (x + a)^2,
x^2 - 2ax + a^2 = 4 + a^2, ⇒ Solve for a
2ax = -2x,
a = - 1, ⇒ Substitute value of a,
x^2 - 2x + 1 = 4 + 1,
( x - 1 )^2 = 5, ⇒ Solve for x,
x = √5 + 1, and x = - √5 + 1,
In other words; <em>Solution : x = 1 + ( √ 10 )/ 2, or x = 1 - ( √ 10 )/ 2; Option A</em>
Answer:
x-intercept= 12
y-intercept=-4

Answer:
Should be a 33.33% increase
Step-by-step explanation:
320 divided by 240 to get 1.33, anything above 1 is increase, so its a 33% increase.
ANSWER:
Kevin made $800 in commissions last week.
EXPLANATION:
Since we know that he only makes money in two ways, by base salary and commission, we know that added together they equal his whole pay.
Therefore we can set up the following equation and solve for his commission amount.
Total Pay = Base Pay + Commissions.
- 1125 = 325 + Commissions.
- 800 = Comissions.
