(2x² - 7x - 10) = (x - 4).

Mathematics
1 answer:

5 0

(2x^2 - 7x - 10) = (x - 4)

2x^2 - 7x - 10 - x - 4 = 0

2x^2 - 8x - 14 = 0

x^2 - 4x - 7 = 0

x^2 - 4x = 7

x^2 - 4x + (2)^2 = 7 + (2)^2

(x - 2)^2= 11

x - 2 = squared root (11) x - 2 = -squared root 11

x = 2 + squared root 11 x = 2 - squared

Y&gt;-3x +3<br> y≥ 2x-2<br> O (1,0)<br> O (-1,1)<br> O(2,2)<br> (0,3)
Ainat [17]

Answer:

(1,0)

Step-by-step explanation:

y>-3x +3

y≥ 2x-2

If we plot these two inequalities, we can see where the lines intersect,  See attached graph.

They intersect at (1,0)

We can also do this mathematically:

  y>-3x +3

<u>- (y≥ 2x-2)</u>

0 \geq -5x + 5

5x \geq 5

x \geq 1

If x = 1:

y≥ 2x-2

y≥ 2(1)-2

y≥ 0

(x,y) = (1,0)

Which ratio would help find the distance the person is from the flag pole ¨X¨ if the angle is elevation of 30 degrees.
WINSTONCH [101]

Answer:

There are three major trignometric ratios in mathematics and they are:

sine(sin), cosine(cos) and tangent(tan). A popular acronym is used in recalling the formula for each ratio and it is: SOH-CAH-TOA.

Sine(x) = Opp/Hyp

Cosine(x) = Adj/Hyp

Tangent(x) = Opp/Adj

Now, the Hyp is the hypothenus of the triangle and it is the side opposite to angle 90. The opposite and adjacent is kind of relative depending on the angle been considered. For this case, we are considering angle 30 which the opposite side is 60 and the remaining side becomes the adjacent

Step-by-step explanation:

tan 30 = 60/x
