The second graph is linear because it is a straight line. The first and last graph are non linear because they curve. Linear means a straight line and non linear is not straight. The second graph is also positive because the line is going up. To know if a linear line is positive write your name, and which ever way it goes shows if it’s positive or negative.

Determine the number of possible triangles, ABC, that can be formed given A = 30°, a = 7, and b = 18.

zzz [600]

Answer:

none

Step-by-step explanation:

We are given a triangle ABC with ∠A = 30°, sides a = 4 and b = 10.

According to the 'Law of Sines- Ambiguous Case', we have,

If a < b×sinA, then no triangle is possible.

If a = b×sinA, only one triangle is possible

If a > b×sinA, two triangles are possible.

So, we have,

b×sinA = 10 × sin30 = 10 × 0.5 = 5.

Now, as

4 = a < bsinA = 5.

We get, according to the rule, no triangle is possible.

A government buys `x`fighter planes at `z` dollars each, and `y` tons of wheat at w dollars each. It spends a total of `B`dollar

Veronika [31]

The equation whose solution is the given quantity is 90,000,000 = 2,000,000w + 15,000w where w = $44.67

<h3>Equation</h3>

B = xz + yw

Where,

B = Total cost = 90
x = number of fighter plane = 20
y = tons of wheat = 15,000
w = cost of each tons of wheat
z = cost of fighter plane
z = 100,000w

B = xz + yw

90,000,000 = (20 × 100,000w) + (15,000 × w)

90,000,000 = 2,000,000w + 15,000w

90,000,000 = 2,015,000w

w = 90,000,000 / 2,015,000

= 44.6650124069478

Approximately,

w = $44.67

Find the slope of the line that passes through the coordinates (3,-6) and (-9,2)

JulsSmile [24]

9514 1404 393

Answer:

-2/3

Step-by-step explanation:

The slope formula is useful for this.

m = (y2 -y1)/(x2 -x1)

m = (2 -(-6))/(-9 -3) = 8/-12

m = -2/3

The slope of the line is -2/3.

The graph shows the two points and a line with a slope of -2/3.
