All you do for #4 and # 5 is plug the x values FROM THE TABLE into the equation, and see if you get the y values listed in the table. You don't, so you can see that the equations DO NOT REPRESENT THE DATA IN THE TABLE. For #6 you can see from the graph that one point on the line is (1,-2) which does represent the table of values. Looking further, as each x value decreases by 1, the y value decreases by 3, so (0,-5) makes sense too, again supporting the idea that the graph DOES represent the table of values

Change 1.234 to a percent
Nookie1986 [14]

Answer:

1.234 / 100  =  0.01234

Therefore;

0.01234 x purchase price = profit

same as

purchase price  / 1.01234  = profit

formula    Cost or initial Price   x    (  % / 100 )

and show % as a  whole number ie ) 1.234 / 100 = 0.01234

= cip x 1.01234 = profit

When we divide by 100 the 1 moves two spaces to the right.

when we have to find initial price from given sale price

we deduct given percentage from 100% and use that to multiply with instead omitting the 1 if its depreciating or adding the 1 if its original price ticket.

What's the inequality for |u|-2<5
Andrew [12]

Answer:

0 ≤ u < 7 and 0 > u > - 7 and combining those two we get - 7 < u < 7.

Step-by-step explanation:

The given inequality is |u| - 2 < 5 ....... (1)

We have to solve this inequality.

Now, from the definition of f(x) = |x| we get, f(x) = x, when x ≥ 0 and  

f(x) = -x when x < 0.

Hence, for u ≥ 0, the equation of inequality (1) becomes  

u - 2 < 5

⇒ u < 7

Therefore, the solution is 0 ≤ u < 7 (Answer)

Again, for u < 0, the equation of inequality (1) becomes

- u - 2 < 5

⇒ u + 2 > - 5

⇒ u > - 7

Therefore, the solution becomes 0 > u > - 7 (Answer)

What is the equation of the line that passes through the points (6,8) and (-3,2)
Vikki [24]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (6, 8) and (-3, 2). Substitute:

m=\dfrac{2-8}{-3-6}=\dfrac{-6}{-9}=\dfrac{2}{3}\\\\y-8=\dfrac{2}{3}(x-6)\qquad|\text{use distributive property}\\\\y-8=\dfrac{2}{3}x-4\qquad|+8\\\\y=\dfrac{2}{3}x+4\qquad|-\dfrac{2}{3}x\\\\-\dfrac{2}{3}x+y=4\qquad|\cdot(-3)\\\\2x-3y=-12

Answer:

point-slope form: y-8=\dfrac{2}{3}(x-6)

slope-intercept form: y=\dfrac{2}{3}x+4

standard form: 2x-3y=-12
