Answer:

y = 5x+ 19

Step-by-step explanation:

For parallel lines, the slopes are the same.

y= mx+c

By substituting the values, we get

9=5(-2)+c

19= c

Thus, the equation is y = 5x+19

Need help please its my last question

Nesterboy [21]

Given:

Radius of circle = 12 units

Area of sector = 24π sq. units.

Central angle = x

To find:

The value of x.

Solution:

We have,

$r=12$

$A=24\pi$

$\theta = x$

We know that, area of a sector is

$A=\dfrac{\theta }{360^\circ}\pi r^2$

Where, $\theta$ is central angle, r is radius.

$24\pi=\dfrac{x}{360^\circ}\pi (12)^2$

$24\pi=\dfrac{x}{360^\circ}\pi (144)$

$\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}$

$\dfrac{1}{6}=\dfrac{x}{360^\circ}$

Multiply both sides by 360 degrees.

$\dfrac{1}{6}\times 360^\circ=x$

$60^\circ=x$

The value of x is 60 degrees.

Therefore, the correct option is A.

Step-by-step explanation:

5) 2.4×10^-5 / 4.5×10^-11

2.4×10^-5= 0.000024
4.5×10^-11= 0.000000000045

=0.000024/0.000000000045

=24/1 × 1,000,000/45

=24,000,000/45

=533,333.33°

=5.33333°×10^5

2x + 3 = 5x - 2

2x - 5x = - 2 - 3
-3x = -5
x = -5/-3
x = 1.66°

6x + 4 = 6x + 4

6x - 6x = 4 - 4
0x = 0

2 (2x + 3) = 8x - 2

4x + 6 = 8x - 2
4x - 8x = -2 - 6
-4x = -8
x = -8/-4
x = 2

-3x + 2 = -3x + 5

-3x + 3x = 5 - 2
0x = 3

Letter be has no solution because it is broken down as "0x = 0"

A pile of coins, consisting of quarters and half dollars, it worth $11.75. If there are 2 more quarters than half dollars, how m

lord [1]

Let the number of half dollars be x,

number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17

There are 17 quarters and 15 half dollars.
