Answer:
b
Step-by-step explanation:
We are given one angle that is 3 times less than others. Let us assume one angle measure is x degrees and another is 4x. Because x is 3x less than 4x. ( We can check 4x-x= 3x) Sum of complementary angles is 90 degrees. So, we can set up an equation, First angle measure + first angle = 90 degrees. x+4x = 90. Adding x and 4x, we get 5x. So, 5x = 90. Dividing both sides by 5, we get 5x/5 = 90. x= 18. So, one angle is 18 degrees. Another angle = 4x = 4 times 18 = 72 degrees. So, the required angles are of 18 degrees and 72 degrees.
Slope intercept form is y=mx+b so use your numbers to fill in the blanks
heres an example:
Answer:
No, because the amount of money on her gift card should decrease each week.
Step-by-step explanation:
Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.
Proof I got it correct:
I might be misreading something here but if:
x^5+243=0 subtract 243 from both sides
x^5=-243 raise both sides to the 1/5 power (or take the fifth root of both sides)
x=-3
So there is only one solution, x=-3
