The answer is A) (4, -7).

You wanna substitute the choices in the problem.

y = 2x - 15

4x + 3y = -5

-7 = 2(4) -15

-7 = 8 -15

8 - 15 = -7

-7 = -7

4(4) + 3(-7) = -5

16 + -21 = -5

-5 = -5

So (4, -7) is a solution to the equations.

Hope this Helps!!

A. (4, -7) Is the correct answer!

2 x 4 = 8 8 - 15 = -7 True!

4 x 4 = 16 3 x -7 = -21 16 + -21 = -5 True!

Since both statements are true, this is the solution to the system.

Evaluate 2 sin 60° + tan 45° + cos²60°

DerKrebs [107]

Answer:

1.25+√3 or 2.9821 to the nearest ten thousandth.

Step-by-step explanation:

sin 60 = √3/2, tan 45 = 1 and cos^2 60 = (1/2)^2 = 1/4

So we get 2 *√3/2 + 1 + 1/4

= √3 + 1.25

CAN SOMEONE PLEASE HELP ME ASAP PLEASEEEE!!!

Answer:

11.4

Step-by-step explanation:

So we know that Triangle ACB is similar to Triangle EFD.

This means that their sides are proportional to each other.

We want to find x or side AB. To do so, we can set up a proportion.

The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:

$\frac{AB}{ED}=\frac{BC}{DF}$

Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:

$\frac{x}{3.8}=\frac{15}{5}$

Reduce the right:

$\frac{x}{3.8}=\frac{3}{1}$

Cross multiply:

$x=11.4$

So, the value of x is 11.4

And we're done!
