Answer:

  • See below

Step-by-step explanation:

  • 1) Total points = 25
  • 2) Points earned = 21
  • 3) Percent score = 84%

<u>Proportion:</u>

  • 21 / 25 = 84% / 100%

Solving the others in the table

<u>21 out of 25 points:</u>

  • 21/25 = x/ 100 ⇒ x = 100*21/25 = 84

<u>15 out of 20 points:</u>

  • 15/20 = x/100 ⇒ x = 100*15/20 = 75

<u>47 out of 50 points:</u>

  • 47/50 = x/100 ⇒ x = 100*47/50 = 94

<u>28 out of 30 points:</u>

  • 20 / 30 = x/100 ⇒ x = 100*20/30 = 66.66

<u>19 out of 45 points:</u>

  • 19/45 = x/100 ⇒ x = 100*19/45 = 42.22

<u>3 out of 4 points:</u>

  • 3/4 = x/100 ⇒ x = 100*3/4 = 75

Write an equation for the line parallel to y = -7x + 15 that passes through the point P(9,-6).
Elan Coil [88]

Answer:

y = -7x + 57

Step-by-step explanation:

If the line is parallel, it will have the same slope. So, this line will also have a slope of -7.

Use y = mx + b, plug in the slope and given point, and solve for b:

y = mx + b

-6 = -7(9) + b

-6 = -63 + b

57 = b

Plug in the slope and y intercept into y = mx + b:

y = mx + b

y = -7x + 57

So, the equation is y = -7x + 57

F(x)
Ludmilka [50]
F(x) = 5 + 2x  where x is the number of times he walks the neighbours dog
y-intercept is at y=5 and slope = 2

g(x) :-  As x increases by 4 g(x) decreases by -8  so the slope is -8/4 =  -2
when x = 0, g(x)  = the y intercept  is at -1 + (-8/2) = - 5
so equation of g(x) is  g(x) = -5 -2x
h(x):-    the slope is  (3 - 5) / (1 - 0)      [  difference in y values / diff in x values]
slope = -2
so we have h(x) = -2x + c   where c = the y-intercept
when x = 0  h(x) = 5
so  c = 5
 h(x) = 5 - 2x   

  Now j(x)= 2x - 5   - slope is 2 and y intercept = -5

Help pls reallyyyyyyyyyyyyyyyyyy
Ivan

Answer:

10

Step-by-step explanation:

j=6

k=4

Rewrite the equation. So let's do that-

2.5(6*4)/6

6 and the other 6 cancel out so we are left with 2.5*4

Which is then equal to 10.

By the way, whenever you see the same number in a division problem on the numerator and denominator, just cancel them out because if you still did 2.5(6*4)/6, you would still get 10. I was just simplifying it!

If (3, -5) is an ordered pair of the function f(x), which of the following must be an ordered pair of the inverse of f(x)?
makkiz [27]
You just swap the ordered pair units around. It’d be (-5, 3)
