I think the answer is (-5,8) because if the y=8, that is the y axis, which comes after the x. And -5 +8=3. Hope it is right! Thank you for the points!

Having trouble with this one can someone teach me how to find the slope in this question. Try to help me learn it aswell. Its in

ASHA 777 [7]

Hi there! The answer is -2.

We can find the slope of a formula by using the following formula:

$slope = \frac{change \: of \: y}{change \: of \: x} =\frac{y2 - y1}{x2 - x1}$
x2 and y2 don't mean squared, but the x and y coordinate of our second point.

First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.

$slope = \frac{ - 5 - 3}{1 - - 3} = \frac{ - 8}{4} = - 2$

Therefore, the third answer is correct.
~ Hope this helps you!

A cash register contains only five dollar and ten dollar bills. It contains twice as many five's as ten's and the total amount o

Effectus [21]

Answer:

Step-by-step explanation:

Let number of ten dollar bills be x .

So, number of five dollar bills = 2 x

Total amount of money in the cash register = 620 dollars

Amount of money in total cash as a result of five dollar bills = 2 x × 5 = 10 x dollars

Amount of money in total cash as a result of ten dollar bills = x × 10 = 10 x dollars

According to question ,

Total amount of money in the cash register = Amount of money in total cash as a result of five dollar bills + Amount of money in total cash as a result of ten dollar bills

⇒ 620 = 10 x + 10 x

⇒ 620 = 20 x

⇒ x = $\frac{620}{20}$ = 31

So, number of ten dollar bills = 31

These two scalene triangles are similar with a scale of 4:5. What is true about these figures?

disa [49]

Alright, lets get started.

Lets check each possible answer one by one.

We will start from option B.

BC is from small triangle and its corresponding side is DF, so its ratio will be $\frac{4}{5}$ not $\frac{5}{4}$ as given in option. Hence option B is incorrect.

For option C,

Angle a° and angle f° are not similar angles, if they were similar, then only their ratio will be 1 otherwise not 1. Hence option C is incorrect.

For option D,

Angle c° and angle f° are similar angles so, their ratio will be $\frac{c}{f} = 1$ . Hence option D is incorrect.

Now option A,

ED and AB are corresponding sides. ED is from bigger triangle and AB is from smaller triangle. Their ratio will be $\frac{ED}{AB} = \frac{5}{4}$ . Hence option A is correct answer.

Hope it will help :)
