Answer:

8/5

Step-by-step explanation:

We can use the formula for finding slope for this: $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\frac{1 - (-7)}{9 - 4}$

$\frac{8}{5}$

The answer would be 8/5

Factor the expression. k2 + 5kf – 50f2

g100num [7]

Answer:

We have

k^2 - 25f^2 + 5kf - 25f^2 =

k^2 - (5f)^2 + 5f( k - 5f) =

( k - 5f )( k + 5f ) + 5f( k - 5f ) =

( k - 5f )( k + 5f + 5f ) =

( k - 5f )( k + 10f );

Rewrite each fraction with a denominator of 24 2/3 and 5/8

Tresset [83]

Answer:

2/3 = 16/24

5/8 = 15/24

Step-by-step explanation:

2/3= 16/24

5/8= 15/24

because if you multiply across $\frac{2}{3}$ by $\frac{8}{8}$ equal $\frac{16}{24}$

and if you multiply across $\frac{5}{8}$ by $\frac{3}{3}$ equal $\frac{14}{24}$

Is 6200 ft greater or less than 1 mile 900 ft

Sphinxa [80]

1 mile is equal to 5280 feet

Add 900 to it:

5280 + 900 = 6180

6180 is less than 6200, so 1 mile and 900 feet is less than 6200 feet.

A carpenter has at most $250 to spend on lumber the inequality 8x+12y<250 represents the numbers x of 2 by 8 boards and the n

malfutka [58]

Answer:

The carpenter will not be able to buy 12 '2 by 8 boards' and 14 '4 by 4 boards'.

Step-by-step explanation:

Given:

Amount a carpenter can spend at most = $250

The inequality to represent the amount he can spend on each type of board is given as:

$8x+12y$

where $x$ represents '2 by 8 boards' and $y$ represents '4 by 4 boards'.

To determine whether the carpenter can buy 12 '2 by 8 boards' and 14 '4 by 4 boards'.

Solution :

In order to check whether the carpenter can buy 12 '2 by 8 boards' and 14 '4 by 4 boards' , we need to plugin the $x=12$ and $y=14$ in the given inequality and see if it satisfies the condition or not or in other words (12,14) must be a solution for the inequality.

Plugging in $x=12$ and $y=14$ in the given inequality

$8(12)+12(14)$

$96+168$

$264$

The above statement can never be true and hence the carpenter will not be able to buy 12 '2 by 8 boards' and 14 '4 by 4 boards'.
