ioda2 years ago
7 0

Answer:

m = 21, b = 28

Step-by-step explanation:

1. The equation is written in slope-intercept form, meaning it follows this equation: y = mx + b.

2. As you can see, 21 is the value plugged in where m is, and 28 is the value plugged in where b is.

Therefore, m = 21, and b = 28.

Helpppp meeeee outttttt pleaseeeee ASAPPPP!!!!
Ilya [14]

Answer:

\boxed{\sf sin\ C =\frac{40}{41}}

Step-by-step explanation:

We need to find out the value of sinC using the given triangle . Here we can see that the sides of the triangle are 40 , 41 and 9 .

We know that the ratio of sine is perpendicular to hypontenuse .

\sf\longrightarrow sin\theta =\dfrac{ perpendicular}{hypontenuse}

Here we can see that the side opposite to angle C is 40 , therefore the perpendicular of the triangle is 40. And the side opposite to 90° angle is 41 . So it's the hypontenuse . On using the ratio of sine ,

\sf\longrightarrow sinC =\dfrac{ p}{h}\\\\\sf\longrightarrow sin\ C =\dfrac{AB}{AC}

Substitute the respective values ,

\sf\longrightarrow \boxed{\blue{\sf sin\ C =\dfrac{40}{41}}}

<u>Hence the required answer is 40/41.</u>

PLEASE HELP For the expression below, write two other equivalent expressions using different terms. Make sure one is fully simpl
Julli [10]

Given:

The given expression is

-4(x+2)-2x+4

To find:

The two other equivalent expressions.

Solution:

We have,

-4(x+2)-2x+4

Using distributive property, we get

=-4(x)-4(2)-2x+4

=-4x-8-2x+4

So, one equivalent expression is -4x-8-2x+4.

On further simplification, we get

=(-4x-2x)+(-8+4)

=6x-4

Therefore, the second and fully simplified equivalent expression is 6x-4.

Answer:

7

Step-by-step explanation:

Given,

h ( x ) = 1

To find : -

h ( x ) = 3x + 4

h ( 1 ) = 3 ( 1 ) + 4

= 3 + 4

h ( 1 ) = 7
