Answer:

x = 9

Step-by-step explanation:

-1 + 14x = 12x + 17

Rearrange terms.

14x - 1 = 12x + 17

Add 1 to both sides of the equation.

14x - 1 + 1 = 12x + 17 + 1

Simplify.

14x = 12x + 17 + 1

14x = + 12x + 18

Subtract 12x from both sides of the equation.

14x - 12x = + 12x - 12x + 18

Simplify.

2x = + 12x - 12x + 18

2x = 18

18 ÷ 2 = 9

x = 9

the variables a and B are positive numbers. drag and drop each coordinate point to match the correct quadrant.

inessss [21]

Answer:

Hence,

Quadrant I --------------- ( a , b)

Quadrant II --------------- ( -a , b)

Quadrant III --------------- ( -a , -b)

Quadrant IV --------------- ( a , -b)

Step-by-step explanation:

There our four quadrant divided by the x-axis and y-axis.

So the variables according to the quadrant are given below.

Quadrant I : Both the coordinates are positive.

Quadrant II : x-coordinate is negative and y-coordinate it is positive.

Quadrant III : x-coordinate is negative and y-coordinate it is negative.

Quadrant IV : x-coordinate is positive and y-coordinate it is negative.

Hence,

Quadrant I --------------- ( a , b)

Quadrant II --------------- ( -a , b)

Quadrant III --------------- ( -a , -b)

Quadrant IV --------------- ( a , -b)

Please help!!! it would be much appreciated

Answer:

12/13, or answer choice B

Step-by-step explanation:

Ok first lets find the lengths of this triangle. We know 2 lengths already, 5 and 12. By using the pythagorean theorem, a^2+b^2=c^2, we can figure out that the third side is 13 units long.

Math:

5^2+12^2=169

25+144=169

And the square root of 169 is 13, meaning that the hypotenuse of the right triangle is 13.

To remember what SIN TAN and COS mean, you can use this helpful phrase: SOH CAH TOA

SOH: It means that SIN is OPPOSITE OVER HYPOTENUSE

CAH: it means that COS is ADJACENT OVER HYPOTENUSE

TOA: It means that TAN is OPPOSITE OVER ADJACENT

because it asks for SIN B, we need to do OPPOSITE OVER HYPOTENUSE.

Because the side opposite to angle B is 12 units, and the hypotenuse is 13 units, the answer is 12 over 13 units, or 12/13.

I hope my answer helped!

Determine the equation of the parabola whose graph is given below. Write your answer in General Form. A parabola on a coordinate

dimaraw [331]

The equation of parabola becomes y = -2/25(x-3)^2 + 4.

According to the statement

we have given a graph and from this graph we have to find the equation of parabola in the general form.

So,

we know that the equation of parabola in general form is

y = a(x-h)^2 +k - (1)

From the graph we have:

a point on the graph is (x,y) = (-2,2)

the vertex of the graph is (h,k) = (3,4)

Now, substitute these values in the equation number (1)

Then

y = a(x-h)^2 +k

2 = a(-2-3)^2 +4

2 = a(-5)^2 +4

2 = a(25) +4

25a = -2

a = -2/25.

Now put a = -2/25 and (h,k) = (3,4) in the equation(1).

Then

the equation of parabola becomes y = -2/25(x-3)^2 + 4

So, The equation of parabola becomes y = -2/25(x-3)^2 + 4.

A bird flies from the bottom of a canyon that is 71 4/5 feet below sea level to a nest that is 875 7/10 feet above sea level. Wh

Rainbow [258]

The difference in elevation between the bottom of the canyon and the bird's nest is 947 1/2 feet

<h3>What is the difference in elevation between the bottom of the canyon and the bird's nest?</h3>

The given parameters are:

Nest = 71 4/5 feet above the seal level

Bottom of canyon = 875 7/10 below sea level

Below sea level means negative

So, we have:

Nest = 71 4/5 feet

Bottom of canyon = -875 7/10

The difference in elevation between the bottom of the canyon and the bird's nest is calculated as

Difference = |Nest - Bottom of canyon|

This gives

Difference = |71 4/5 - (-875 7/10)|

Evaluate the difference

Difference = |947 1/2|

Remove the absolute bracket

Difference = 947 1/2

Hence, the difference in elevation between the bottom of the canyon and the bird's nest is 947 1/2 feet
