Answer:

x + 12

Step-by-step explanation:

  • (2)(x)+(2)(7) + (-1)(x) + (-1)(2)
  • 2x + 14 -x -2
  • (2x-x)+(14-2)
  • x + 12

Therefore, the answer is x + 12.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

5g + 4(-5+3g) = 1 - g
Korvikt [17]
5g + 4(-5 + 3g) = 1 - g 
5g - 20 + 12g = 1 - g 
 17g - 20 = 1 - g 
   \frac{18g}{18} =   \frac{21}{18}
    there can be to answer 
      g = \frac{21}{18} or 
      you can simplify \frac{21/3}{18/3} =  \frac{7}{6} or 1 \frac{1}{6}

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 196 feet, and ball 2 is droppe
Anon25 [30]
H1 (t) = 196 - 16 t-squared. / / / H2 (t) = 271-16t-squared. / / / In each function, 't' is the number of seconds after that ball is dropped. / / / Each function is only true until the first time that H=0, that is, until the first bounce. Each function becomes very complicated after that, and we would need more information in order to write it.

Can someone help me with system of equations?
umka21 [38]

#1)

Answer:

x=1 and y=12

Explanation:

y=5x+7

y=2x+10

This system should use substitution because the value of y is given in terms if x.

Substitution:

5x+7=2x+10

Solve:

3x=3

x=1

Substitute x to solve for y by plugging x into one if the original equations(doesn’t matter which one is used).

y=5x+7

y=5(1)+7

y=5+7

y=12

#2)

Answer:

x=-8 and y=2

Explanation:

y=2x+18

9y=-2x+2

This system also uses substitution. The value of y us already given in terms if c in the first equations, so we will substitute in the second equation.

Substitute:

9(2x+18)=-2x+2

Solve:

18x+162=-2x+2

20x=-160

x=-8

Now that we have the value if x, plug it into one of the original equations(doesn’t matter which equation) and substitute to find y.

y=2x+18

Substitute:

y=2(-8)+18

Solve:

y=-16+18

y=2
