How ro turn y + 7 = -5 ( x + 3) into standard form

Mathematics
1 answer:
GuDViN [60]4 years ago

There are many standard forms
there is ax+by=z or slope-intercept form which is y=mx+b
I will do both
first distribute the -5
y+7=-5x-15
add 5x to both sides
5x+y+7=-15
subtract 7 from both sides
5x+y=-22


or slope-intercpt form
distribute -5
y+7=-5x-15
subtract 7 from both sides
y=-5x-22

Help plsssssssss ....
Rom4ik [11]

Answer:

Arccos(0.9272) =0.383929333 radian

0.383929333 radian =(0.383929333*57.2957795)degrees

so, 21.99 degrees

Step-by-step explanation:

Rounding to the nearest we get 22 degrees

We know that,

1 radian is equal to 57.2957795

so we multiply the radian value 0.383929333 with it

I really don't get this. Can someone help please?
kondor19780726 [428]
Okay, so whatever the answer is to angle A its the same answer to angle C and angle B and D. the angle looks like a obtuse which means it has to be bigger than 90 degrees. use your protractor to measure it.

What is the area of the polygon? Show your work.​
koban [17]

Answer:

33 square units

Step-by-step explanation:

Assuming that each line on this grid increases by a value of one, the area of the polygon can be determined by breaking it down into a large rectangle and two smaller triangles.

<h3>Area of the rectangle</h3>

The area of a rectangle is simply A = bh, where b represents the base and h represents the height.

Counting the size of each side, we can determine that they are 6 units for the base and 4 units for the height.

Substituting in the values, we get:

A = (6)(4)\\A = 24

The area of the rectangle is 24 square units

<h3>Area of the triangles</h3>

The area of a triangle is simply A = \frac{1}{2} bh.

The base of each triangle is 3, and the height of each triangle is also 3.

Substituting in the values, we get:

A = \frac{1}{2} (3)(3)\\A =  \frac{1}{2} (9)\\A =  9 / 2\\A = 4.5

The area of each triangle is 4.5 square units

<h3>Area of the polygon</h3>

To get the area of the polygon, we simply add up the area of the rectangle and both triangles

A = 24 + 4.5 + 4.5\\A = 24 + 9\\A = 33

The total area of the polygon is 33 square units.
