Answer:

C 0 solutions

Step-by-step explanation:

8x+47 = 8(x+5)

Distribute

8x+47 = 8x+40

Subtract 8x from each side

47 = 40

This is never true so there are no solutions

Answer:

C. 0

Step-by-step explanation:

8x + 47 = 8(x + 5)

Jan has $130. If she saves $25 per week, in how many weeks will she have $600?
serious [3.7K]

Let's represent the number of weeks with the variable 'w':

130 + 25w = 600

We subtract both sides by 130:

25w = 470

w = 18.8

We round up:

It will take her 19 weeks.

Choose the point-slope form of the equation of this line.​
igor_vitrenko [27]

Answer:

y= -5x +7

Step-by-step explanation:

We can see points on the graph:

  • (2, -3) and (3, -8)

The function in general form is:

  • y= mx+b

Let's find the slope and y-intercept as per identified points on the graph:

  • m= (y1-y1)/(x2-x1)
  • m= (-8+3)/(3-2)= -5

b= y- mx

  • b= - 3 -(-5)*2= -3 +10= 7

Based on the found values of m and b, the given line is:

  • y= -5x +7

Z to the power of 2 =1
stiv31 [10]

That would be written as:

z^{2} = 1


And the step-by-step equation would be:

z^{2} = 1 → we take the 2 to the right side of the equation and do the IO*

z = \sqrt{1} →we solve for \sqrt{1}

z = 1 → final answer


*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)



Hope it helped,
