Step-by-step explanation: 6 22 22 04

it looks like you want to divide 23.584 by 5.97

to estimate this 23.584 is close to 24 and 5.97 is really close to 6

24/6 = 4

Which linear function represents the line given by the point-slope equation y + 7 = –2/3(x + 6)?a. f(x) = –2/3x – 11b. f(x) = –2

Pavel [41]

Answer:

option C

$y=\frac{-2}{3}x-11$

Step-by-step explanation:

The point slope equation of a line is given by

$y-y_1=m(x-x_1)$

Where m is the slope and (x1,y1) is the point on the point

$y + 7 =\frac{-2}{3}(x + 6)$

We need to write the equation in y=mx+b form

multiply -2/3 inside the parenthesis

$y + 7 =\frac{-2}{3}x-4$

Subtract 7 from both sides

$y=\frac{-2}{3}x-11$

Tony and some friends went to the movies. They bought 4 drinks and 2 tubs of popcorn and spent a total of $32.50 on the food. Ea

Travka [436]

1 tub of popcorn = t
1 drink = t - 3.5

4(t - 3.5) + 2t = $32.50
4t - 14 + 2t = 32.5
6t = 32.5 + 14
6t = 46.5
t = 46.5 / 6
t = $7.75

The owner of a shop wants to mix cashews and pecans to make 8 kg of mixed nuts worth $7.25 per kg. If the price of cashews is $8

noname [10]

Answer:

6 kg pecans,

2 kg cashews.

Step-by-step explanation:

Let x be the weight of cashews and y be the weight of pecans in kg.

We have been given that the owner of a shop wants to mix cashews and pecans to make 8 kg of mixed nuts. We can represent this information in an equation as:

$x+y=8...(1)$

We are also told that the mixed nuts worth $7.25 per kg, so the price of 8 kg of mixed nuts will be $\$7.25\times 8=\$58$ .

Since the price of cashews is $8.00 per kg and the price of pecans is $7.00 per kg, so we can represent this information in an equation as:

$8x+7y=58...(2)$

Now we will use substitution method to solve system of equations.

From equation (1) we will get,

$x=8-y$

Substituting this value in equation (2) we will get,

$8(8-y)+7y=58$

$64-8y+7y=58$

$64-y=58$

$64-64-y=58-64$

$-y=-6$

$y=6$

Therefore, the owner should take 6 kg of pecans.

Upon substituting $y=6$ in equation (1) we will get,

$x+6=8$

$x+6-6=8-6$

$x=2$

Therefore, the owner should take 2 kg of cashews.
