Answers

Answer:

x = 0

y = -1

Step-by-step explanation:

Multiply second equation with -1

(-1) * (-3x - 8y) = 8

3x + 8y = -8 now find its sum with the first equation

2x - 8y + 3x + 8y = 8 - 8 add like terms (note that minus 8y will eliminate +8y)

x = 0 to find the value  of y replace the x with 0 in the first equation

2*0 - 8y = 8

-8y = 8 divide both sides by -8

y = -1

Step-by-step explanation:

perimeter of a rectangle = 2( width + length )

Answer:

The measure of <Y = 85 degrees

Step-by-step explanation:

you can solve this problem algebraically if you know that the sum of the interior angles of a triangle is 180 degrees.

if you add all of these angles and set them equal to 180, you can find what "a" is.

a+2a+a+10=180 so 4a+10=180 so a is 42.5 (which is equal to angle x)

then looking at all of the options, it can be seen that the first two options are incorrect because angle x is equal to 42.5 degrees.

you know that angle y is equal to 2a, so multiplying "a" by two, you can find that angle y is 85 degrees.

Answer:

  2. ASA can be used with the definition of an isosceles triangle

  3. x = 5 5/6

Step-by-step explanation:

2.

Using the given information, the definition of an isosceles triangle tells us, ...

  ∠A = ∠C and ∠A = ∠ABM and ∠C = ∠CBN

By substitution, ∠ABM = ∠CBN. This lets us declare ΔAMB ≅ ΔCNB by ASA, where the sides between the angles are AB and CB.

__

3.

If the angles of interest are the same, then the triangles are similar. That means corresponding sides have the same ratio:

  AB/AD = CB/CE

  x/7 = (10-x)/5

  5x = 7(10 -x) = 70 -7x . . . . . multiply by 35, simplify

  12x = 70 . . . . . . . . . . . add 7x

  x = 70/12 = 35/6

  x = 5 5/6

Answer:

Answer:

124°

Step-by-step explanation:

180°( n - 2 )

180° ( 5 - 2 ) = 540°

( 2x - 3 )° + ( 3x - 2 )° + 2( 3x - 4 )° + ( 2x + 7 )° = 540°

( 2x + 3x + 6x + 2x ) + ( - 3 - 2 - 8 + 7 ) = 540

13x - 6 = 540

13x = 546

x = 42

feet below ground level

Answers

The current depth of the hole is at least 20 feet below ground level.

Inequality is an expression that shows the non equal comparison of numbers and variables.

Let d represent the current depth of the hole.

To be at least 40 feet below ground level, he need more than 2 times its current depth.

2d < -40

d < -20

Hence the current depth of the hole is at least 20 feet below ground level.

What are the domain and range of the function below? (In picture)



Answers

Answer:

Domain: [0 , )

Range: (- , 4]

Step-by-step explanation:

I) DOMAIN:

For domain, look along the x axis.

The graph starts from x = 0 and it's ending point isn't given in the graph as it continues moving along the positive x axis.

Hence, it's ending point must be

Domain of a function is:

[minimum point in x, maximum point in x]

=> [0, ∞)

"),(" is used for infinity.

"],[" for points that lie within the domain of the function.

II) RANGE

For range, look along the y axis.

The graph starts at y = 4, and continues moving downwards till infinity.

Range:

[minimum in y, maximum in y]

=> (-, 4]

For parenthesis, same rule as domain will be applied. 4 is naturally greater than all values in negative. Hence, maximum point will be 4 and minimum will be -.

Since n represents photocopies, then we replace n with 32.

0.6+0.08(32)

0.6+2.56

Finally, add.

0.6+2.56=3.16
