Solve each equation <br> 1. 3/4 f + 5 = -5<br> 2.-1/5 b - 2/5 = -2<br> Please show work
anzhelika [568]
Sole for f by simplifying both sides of the equation then isolating the variable so that means f=-40 over 3 for number one

for the second equation you do the same thing you did for number one and the answer will be
                                  b=8

Analyze the diagram below and complete the instructions that follow.
Phantasy [73]

Answer:

Option (B)

Step-by-step explanation:

From the figure attached,

ΔBCD and ΔACE are the similar triangles.

Therefore, by the property of similar triangles, corresponding sides of these similar triangles will be proportional.

\frac{AC}{BC}= \frac{EC}{DC}

\frac{AB+BC}{BC}= \frac{ED+DC}{DC}

\frac{AB+6}{6}= \frac{24+8}{8}

\frac{AB+6}{6}= \frac{32}{8}

\frac{AB+6}{6}=4

AB + 6 = 24

AB = 18

Option (B) will be the answer.

In triangle abc angle a +angle b =90 then sin a =
Ivan

Answer:

sin(a)=cos(b)

Step-by-step explanation:

we know that

In the triangle abc

if m\angle a+m\angle b=90^o

then

m\angle c=90^o

Because, the sum of the interior angles in a triangle must be equal to 180 degrees

therefore

Triangle abc is a right triangle

see the attached figure to better understand the problem

The sine of angle a is equal to divide the opposite side to angle a by the hypotenuse

so

sin(a)=\frac{x}{z}

The cosine of angle b is equal to divide the adjacent side to angle b by the hypotenuse

so

cos(b)=\frac{x}{z}

therefore

sin(a)=cos(b)

When two angles are complementary, the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle

so

sin(a)=cos(b)

cos(a)=sin(b)

What is the slope of a line that is parallel to the line represented by the equation x-y=8
coldgirl [10]
The slope of x-y=8 is 1 because it's actually y = x-8

Parallel means the slope is equal to 1 as well.
