What is −5x+4y=3<br> x=2y−15<br> ​
jeka57 [31]

Answer:

x=9

y=12

Step-by-step explanation:

you know what the value of x is in terms of the second equation

so put that value into the first equation

so

-5(2y-15) + 4y = 3

-10y + 75 + 4y = 3

-6y + 75 = 3

-6y = -72

y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)

x = 2(12) - 15

x = 24 - 15

x = 9

Find sin A for the triangle below. Give the exact value as an expression and an approximation to the nearest ten-thousandth. Not
Feliz [49]

the exact value of sin A  to the nearest ten- thousandth is 0. 6625

<h3>Using the pythagorean theorem</h3>

a² + b² = c²

The opposite side is unknown, so use the pythagorean theorem to find it

c = hypotenuse = 4

a= opposite site = ?

b= adjacent side = 3

Substitute into the formula

4² = a² + 3²

16 = a² + 9

a² = 16 -9 = 7

Find the square root

a =√7 = 2. 65

To find Sin A, use

Sin A = opposite side ÷ hypotenuse

Sin A = 2. 65 ÷ 4 = 0. 6625

Thus,  the value of sin A is 0. 6625
