Mathematics
1 answer:
const2013 [10]3 years ago
5 0

Answer:

y=3x-2

Step-by-step explanation:

\frac{4-(-11)}{2-(-3)} =\frac{15}{5} =3

m=3 so using point-slope intercept form

y-y_{1}=m(x-x_{1} )

y-4=3(x-2)

       3x-6

+4        +4

y=3x-2

In a certain clothing store, 4 shirts and 6 ties cost $70, and 2 shirts and 4 ties cost $42. What is the cost of each tie?
Oksanka [162]

Answer:

  $7

Step-by-step explanation:

Your two equations are ...

  • 4s +6t = 70
  • 2s +4t = 42

Double the second equation and subtract the first:

  2(2s +4t) -(4s +6t) = 2(42) -(70)

  2t = 14 . . . . . simplify

  t = 7 . . . . . . . divide by 2

The cost of each tie is $7.

The Royal Fruit Company produces two types of fruit drinks. The first type is 20% pure fruit juice, and the second type is 95% p
enot [183]

Answer:

14 pints of 20% juice

56 pints of 95% juice

Step-by-step explanation:

Let

x be pints of 20% pure fruit juice, thus

70 - x   will be pints of 95% pure fruit juice

The equation, thus can be written as:

20%x + 95% (70-x) = 80% (70)

Solving for x:

(0.2)x + (0.95)(70-x) = (0.8)(70)\\0.2x+66.5-0.95x=56\\0.75x=10.5\\x=14

And 70 - x would be 70 - 14 = 56

Thus,

14 pints of 20% juice is needed, and

56 pints of 95% juice is needed

Multiply 4(x+6)/(x−2)⋅(x+10)/24(x+6)
liq [111]

Answer:

Step-by-step explanation:

4(x+6)/(x-2)*(x+10)/24(x+6)

First we do 4(x+6)

4x+24

Then we do 24(x+6)

24x+144

So we plug it in

4x+24/x-2*x+10/24x+144
