F(x)=4x-3, g(x)=10-x Work out gf(x)?

Mathematics
1 answer:
Sedbober [7]2 years ago
3 0

Step-by-step explanation:

Given

f(x) = 4x - 3

g(x) = 10 - x

So Now

gf(x) = g( 4x - 3)

= 10 - 4x + 3

= 13 - 4x

Hope it will help :)❤

Use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage ofthe total va
Vikentia [17]

Answer:

Step-by-step explanation:

The coefficient of determination = r^{2}  = 0.885^{2} = 0.7832

It means about 78% variation in waist size of males can be explained by their weight and about 23% can not be explained.

Two basketballs are thrown along different paths. Determine if the basketballs’ paths are parallel to each
Paul [167]

Answer:

Since the slopes of the two equations are equivalent, the basketballs' paths are parallel.

Step-by-step explanation:

Remember that:

  • Two lines are parallel if their slopes are equivalent.
  • Two lines are perpendicular if their slopes are negative reciprocals of each other.
  • And two lines are neither if neither of the two cases above apply.

So, let's find the slope of each equation.

The first basketball is modeled by:

\displaystyle 3x+4y=12

We can convert this into slope-intercept form. Subtract 3<em>x</em> from both sides:

4y=-3x+12

And divide both sides by four:

\displaystyle y=-\frac{3}{4}x+3

So, the slope of the first basketball is -3/4.

The second basketball is modeled by:

-6x-8y=24

Again, let's convert this into slope-intercept form. Add 6<em>x</em> to both sides:

-8y=6x+24

And divide both sides by negative eight:

\displaystyle y=-\frac{3}{4}x-3

So, the slope of the second basketball is also -3/4.

Since the slopes of the two equations are equivalent, the basketballs' paths are parallel.

Answer:

Step-by-step explanation:

i'll do a few of them

1)   one inch plus a half inch plus an eighth inch plus a sixteenth inch

     1 + 1/2 + 1/8 + 1/16         read the tick marks

     1 + 8/16 + 2/16 + 1/16    find a common denominators

     1 and 11/16                    add the sixteenth numerator

2)

3)

4)  6 inch  plus an eighth inch plus a sixteenth inch

     6 +  1/8 + 1/16         read the tick marks

     6 + 2/16 +  1/16       find a common denominators

     6 and 3/16              add the sixteenth numerator

5)   nine inch plus a quarter inch plus an eighth inch

     9  + 1/4 + 1/8          read the tick marks

     9 + 2/8 + 1/8          find a common denominators

     9 and 3/8              add the sixteenth numerator
