Answer:

y = 1 · 5^x

Step-by-step explanation:

Use the given values in the given formula and solve for 'a' and 'b'.

y = a·b^x

5 = a·b^1 . . . . . . for (x, y) = (1, 5)

125 = a·b^3 . . . . for (x, y) = (3, 125)

Divide the second equation by the first:

125/5 = (a·b^3)/(a·b^1)

25 = b^2 . . . simplify

5 = b . . . . . . . take the square root

Substituting into the first equation, we can find 'a':

5 = a·5

1 = a . . . . . . . divide by 5

Written in the given form, the equation is ...

y = 1 · 5^x

Find the solution to the system of the equations shown below: y = -4x + 11<br>y=1/2x+2

Sav [38]

Hello!

$\large\boxed{x = 2}$

Set the two equations equal to each other to solve:

y = -4x + 11

y = 1/2x + 2

-4x + 11 = 1/2x + 2

Add 4x to both sides:

-4x + 4x + 11 = 1/2x + 2 **Convert 4x into 8/2x***

11 = 9/2x + 2

Subtract 2 from both sides:

11 - 2 = 9/2x + 2 - 2

9 = 9/2x

Divide both sides by 9/2:

9 * (2/9) = 9/2x * (2/9)

x = 2.

I dont understand how to do this

Airida [17]

The statement EF=2.GF (Option A) and the statement

$\frac{\sqrt{3} }{2} .EF=GE$ (Option C) are true for the ΔEFG.

<h3>What are trigonometric ratios?</h3>

The six trigonometric ratios of a right-angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. Trigonometric ratios are used to measure the sides of the right triangle.

Given that in ΔEFG, m∠E=30°, m∠F=60° and m∠G=90°.

Wow, sin 30° $=\frac{GF}{EF}$

⇒ $\frac{1}{2} =\frac{GF}{EF}$

⇒EF=2.GF

and sin 60° $=\frac{GE}{EF}$

⇒ $\frac{\sqrt{3} }{2} =\frac{GE}{EF}$

⇒ $\frac{\sqrt{3} }{2} .EF=GE$

Therefore, the statement EF=2.GF (Option A) and the statement $\frac{\sqrt{3} }{2} .EF=GE$ (Option C) are true for the ΔEFG.

the ratio of blue marbles to white marbles in a bag is 4 to 5 . at this rate, how many blue marbles are there if there are 15 wh

Aleksandr-060686 [28]

4:5 = x : 15
let x be blue marbles
4(15) = 5x
x = 12
therefore 12 blue marbles
