Huh, this is presented pretty interesting to me.

To start with, if you actually had no idea what the answer to this question was, you wouldn't pick B or C because x has to be close to 91°. In this particular quadrilateral, it's especially important that we focus on the fact, "x - 15." This means that x has to be higher initially to be subracted to equal 91, or the opposite angle.

In order to subtract to 91, the answer would have to be 106, or D. This is a hunch, but I have a suspicion that angle B and D are going to be the same, being that their on opposite sides of the figure.

Hope this helps! If you have further questions, let me know.

The sum of the roots of 3x 2 + 11x - 4 = 0 is -11/3 -4/3 11/3 4/3

givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$ .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

$3x^2+11x-4=0$ ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

$\frac{-b}{a}=-\frac{11}{3}$

The sum of roots is $-\frac{11}{3}$ .

Therefore the correct option is 1.

Find the miles per second traveled if one travels 40 miles in 4 hours.

katovenus [111]

$\dfrac{40 \textrm{ miles}}{4 \textrm{ hours}} \times \dfrac{1 \textrm{ hour}}{60 \times 60 \textrm{ seconds}} = \dfrac{1}{360} \textrm{ miles per second}$

Which choice has the same equation in both forms?

Soloha48 [4]

Answer:

8x + 4y = 12 & y = -2x + 3 are the same equations.

Step-by-step explanation:

To know which choice has the same equation in both forms, we need to transform the standard form into the slope intercept form.

Then, solving for y in the first equation, we get:

$8x + 4y = 12\\8x + 4y - 8x = 12 -8x\\4y=12-8x\\\frac{4y}{4}=\frac{12-8x}{4} \\y=3 - 2x\\y=-2x+3$

It means that 8x + 4y = 12 & y = -2x + 3 are the same equations.

At the same way, we get that:

6x + 3y = 18 & y = 2x + 6 are not the same equation:

$6x + 3y = 18\\6x + 3y - 6x = 18-6x\\3y=18-6x\\\frac{3y}{3}=\frac{18-6x}{3} \\y=6 - 2x\\y=-2x+6$

2x + 4y = 8 & y = -2x + 2 are not the same equation:

$2x + 4y = 8\\2x + 4y -2x= 8-2x\\4y=8-2x\\\frac{4y}{4}=\frac{8-2x}{4}\\ y=2-\frac{1}{2}x$

3x + 4y = 12 & y = ¾x + 3 are not the same equation:

$3x + 4y = 12\\3x + 4y -3x= 12-3x\\4y=12-3x\\\frac{4y}{4}=\frac{12-3x}{4}\\ y=3-\frac{3}{4}x$

Ratios Equivalent to 15:6 (not 6:15) Pls tell me what ratios they are

telo118 [61]

Answer:

5:2 , 30:12 , 60:24 , etc.

Step-by-step explanation:

To identify ratios equivalent to 15:6, all you need to do is multiply or divide both numbers in the ratio by the same amount to find an equivalent ratio.

So, for example:

1:2 --> 1*2 : 2*2 = 2:4 Both one half, so equal.

Now for 15:6...

Let's divide by the least common denominator ( 3 )

15 / 3 and 6 / 3 = 5 and 2

So 15:6 = 5:2

And we can also multiply the ratio by any constant as well...

For example 15 * 2 and 6 * 2

So 30:12 = 15:6

Hope this helped!
