-2
-1/2
1/2
2

Answers

Answer 1

Answer:

-1/2

Step-by-step explanation:

2x-y=7

y=2x-7

This line has a slope of 2, a line perpendicular to this line will have a reciprocal number to the slope of this line.

Which means another line is perpendicular to this line will have a slope of -1/2

Find the amount of degrees in x, if the three angles of a triangle are 2x, 2x, and 32 degrees.

Answers

Answer: 2x=74

Step-by-step explanation:

Every triangle is 180 degrees.

so you will take 180-32= 148

then with that you will add up the x's and there are 4...

so then you will take 148/4 and get the answer of...

148/4=37

x=37

but it asked for 2x

37*2

2x=74

final answer is 74

Verify that a + ( b + c) = (a + b) + c , a = (-12) , b = 4 , c = (-25)

Answers

Answer:

a + (b + c) = (a + b) + c

Step-by-step explanation:

a= (-12), b = 4, c = (-25)

[tex](12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33[/tex]

Answer:

GIVEN :-

a = -12b = 4c = -25

TO VERIFY :-

a + (b + c) = (a + b) + c

SOLUTION :-

Find the values of L.H.S. & R.H.S.

L.H.S. :-

Put all values in → [tex]\boxed{a+(b+c)}[/tex]

⇒ -12 + [4 + (-25)]

⇒ -12 + (4 - 25)

⇒ -12 + (-21)

⇒ -12 - 21

⇒ -33

R.H.S. :-

Put all values in → [tex]\boxed{(a+b)+c}[/tex]

⇒ (-12 + 4) + (-25)

⇒ -8 - 25

⇒ -33

CONCLUSION :-

L.H.S. = R.H.S.

⇒ a + (b + c) = (a + b) + c

Sam’s gross income is $1800 every other Friday. Calculate his net income, for one paycheck, if his Federal tax rate is 10% and his State tax rate is 3%.

Answers

Answer:

I believe the answer is $1571.4

Step-by-step explanation:

1800 - 10% = 1620

1620 - 3% = 1571.4

The net income of Sam will be $ 1571.4.

It is given that Sam's gross income is $1800 every other Friday. He has to pay two taxes i.e., 10 % federal tax rate and 3% state tax rate.

We have to calculate his net income.

What is the value of 18 % of 300 ?

The value will be 54.

As per the question Sam's gross income is $1800 , every other Friday.

He has to pay some Federal tax rate , so 10 % will be deducted from gross income.

⇒ 1800 - 10% = $ 1620

Now , he has to pay some State tax rate , so 3 % will be deducted from gross income.

⇒ 1620 - 3% = 1571.4

Thus , his net income will be $ 1571.4.

23x+68x-2=180
X=2

Justify: Same side interior angles

Answer:

Measure of obtuse angle is 134 degrees

Step-by-step explanation:

these two angles are supplementary so they add up to 180

68x-2 +23x=180

91x-2=180

91x = 182

x = 2

plug in x
