Answer 1

Answer: The sum of 4 and 5 has to be equal to : 180 degrees. Because they make a straight angle (which its measure is 180). So we know '4' 108:
${ 108 }^( o )+\quad '5'\quad =\quad { 180 }^( o )\n '5'\quad =\quad { 180 }^( o )\quad -\quad { 108 }^( o )\n '5'\quad =\quad { 72 }^( o )$

5 is equal to ${ 72 }^( o )$

Answer 2

Answer: Angle 5 is 72 degrees. due to supplementary angles

Use the given function f(x) = (x-4) +8x to solve f(-2)A. 18
B. 14
C. 22
D. -22

Answers

we just need to substitute the x by -2 in the function:
f(x) = (x - 4) + 8x
f(-2) = (-2 - 4) + 8(-2)
f(-2) = (-6) - 16
f(-2) = -6 - 16
f(-2) = -22

What is the answer to this equation 35 = - 5/9x

Answers

35 = - 5/9x

mutiply both sides by -9/5

35*-9/5= -5/9x*-9/5

Cross out 5 and 35, divide by 5.

35/5= 7

-5/5= -1

Cross out the 5 and 5 , divide by 5.

Cross out the 9 and 9, divide by 9.

then becomes 1*1*x= x

7*-9= -63

Answer : x= -63

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?

Answers

We know from the question that Store A charges $1200 for repairs and 6% as sales tax.
Then
Amount of sales tax charged by Store A = (6/100) * 1200
   = 6 * 12
   = 72 dollars
Then the total amount charged by Store A = ( 1200 + 72) dollars
   = 1272 dollars
Now coming to Store B. It charges $1350 for repairs and 7% of sales tax.
Amount of sales tax charged by Store B = (7/100) * 1350
   = 945/10
   = 94.5 dollars
Then the total amount charged by Store B = ( 1350 + 94.5) dollars
   = 1444.5 dollars
Amount of money saved by choosing Store A instead of Store B = (1444.5 - 1272) dollars
   = 172.5 dollars
So $172.5 is saved by choosing Store A over Store B.

The total repair cost for each store is the cost of repairs added to the sales tax. The amount of money saved will be the difference between the two total costs.

Answer:

$(7x + 7)/((x-3)(x+4))$

Excluded values are 3 and -4

Step-by-step explanation:

To simplify the expression multiply to create a common denominator.

Multiply the first fraction by (x-3) and the second fraction by (x+4).

$(3)/(x+4) + (4)/(x-3)\n\n(3(x-3))/((x+4)(x-3)) + (4(x+4))/((x-3)(x+4))$

$(3(x-3))/((x+4)(x-3)) + (4(x+4))/((x-3)(x+4)) \n\n(3(x-3) + 4(x+4))/((x-3)(x+4))\n\n(3x - 9 + 4x + 16)/((x-3)(x+4))\n\n(7x + 7)/((x-3)(x+4))$

Excluded values are values which make the denominator 0. This means (x-3)(x+4) cannot be 0. This means x cannot be 3 or -4. These are excluded values.
