We need a graph to be able to give an answer however,

it should follow this formula,

a+bi

where a is the real aspect of the point and b is the imaginary aspect.

Hope this helps.

8x=-11y+24 linear equation in standard form

Klio2033 [76]

Standard form is Ax + By = C. We need to subtract 11y. This gives us 8x + 11y = 24.

The standard form of 8x = -11y + 24 is 8x + 11y = 24.

Tommy multiplied 0.24 by 100 to change it to what type of number?

wlad13 [49]

Percent.

It wouldn’t be a decimal because 0.24 x 100 = 24
It wouldn’t be a fraction because it would be a whole number
It wouldn’t be a benchmark percent because it’s not 25, 50, 75 or 100

20 points.<br><br> Round off x to the nearest tenth.

Valentin [98]

Answer:

$x=15.3$

Step-by-step explanation:

In right triangles only:

The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)

The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)

Therefore, we have the following equation:

$\sin 58^{\circ}=\frac{x}{18},\\x=18\sin 58^{\circ}\approx \boxed{15.3}$

Alternative:

$\cos 32^{\circ}=\frac{x}{18},\\x=18\cos32^{\circ}\approx \boxed{15.3}$
