Determine the slope of the line that passes through the points: x−8,0,4,5,y,−33,−1,15,19

Volgvan

Answer:

The equation of a line y = ax + b passes point (-8, -33) and point (0, -1) can be formulated by:

(Note: we do not need all of 4 points, 2 points are enough)

-33 = a x (-8) + b

-1 = a x 0 + b

From 2nd equation, we have:

b = -1

From 1st equation, we have:

b - 8 x a = -33

=> -1 - 8 x a = -33

=> 8 x a = 32

=> a = 4

=> The equation of line: y = 4a - 1

Hope this helps!

Annie spent 2.5 hours doing homework. She spent 1/3 of the time on her history project. She spent 3/5 of the remaining time solv

Scilla [17]

Step-by-step explanation:

2.5 hours = 150 min

1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover

3/5 of 100 min is 60 min (1 hour) = 40 min leftover

She spent 40 min writing her essay

A breed of cattle needs at least 10 proteins and 8 fats units per day. Feed type I provides 6 protein and 2 fat units at $4 per

Vikki [24]

Let the number of bags of feed type I to be used be x and the number of bags of feed type II to be used be y, then:

We are to minimize:

C = 4x + 3y

subject to the following constraints:

$6x+2y\geq10 \\ \\ 2x+3y\geq8 \\ \\ x\geq0,\ y\geq0$

From the graph of the 4 constraints above, the corner points are (0, 5), (1, 2), (4, 0).

Testing the objective function for the minimum corner point we have:

For (0, 5):
C = 4(0) + 3(5) = $15

For (1, 2):
C = 4(1) + 3(2) = 4 + 6 = $10

For (4, 0):
C = 4(4) + 3(0) = $16.

Therefore, the combination that yields the minimum cost is 1 bag of type I feed and 2 bags of type II feed.

8 in. 8 in. 8 in. Find the area of the figure above. [? ] in.2

solniwko [45]

Answer:

Hello! answer: 96

Step-by-step explanation:

Formula for finding area in squares: base × height

Formula for finding area in triangles: base × height ÷ by 2

8 × 8 = 64 8 × 8 ÷ 2 = 32 64 + 32 = 96 therefore the area is 96 HOPE THAT HELPS!
