1 answer:
Marrrta [24]3 years ago
6 0

Answer:

x=7,3

Step-by-step explanation:

x^2-8x+14=2x-7

Add 8x to both sides.

x^2+14=10x-7

Add 7 to both sides.

x^2+21=10x

x^2+7*3=10x

(x*7)+(x*3)=10x

x=7,3

Hope this helps plz hit the crown :D

two ships leave a port at the same time. the first ship sails on a bearing of 55° at 12 knots (natural miles per hour) and the s
Korvikt [17]

Answer:

37.59 nautical miles

Explanation:

Distance = Speed x Time

The speed of the first ship = 12 knots

Thus, the distance covered after 1.5 hours

\begin{gathered} =12\times1.5 \\ =18\text{ miles} \end{gathered}

The speed of the second ship = 22 knots

Thus, the distance covered after 1.5 hours

\begin{gathered} =22\times1.5 \\ =33\text{ miles} \end{gathered}

The diagram representing the ship's path is drawn and attached below:

The angle at port = 90 degrees.

The triangle is a right triangle.

Using Pythagorean Theorem:

\begin{gathered} c^2=a^2+b^2 \\ c^2=18^2+33^2 \\ c^2=324+1089 \\ c^2=1413 \\ c=\sqrt[]{1413} \\ c=37.59\text{ miles} \end{gathered}

The two ships are 37.59 nautical miles apart after 1.5 hours.

C. Write an equation of the line that contains the given point and has the given slope. Write the equation in slope intercept fo
Harlamova29_29 [7]

Answer:

Step-by-step explanation:

For the first problem, we can plug in the slope of -5 for m:

y = -5x + b

To solve for b, we plug in the given point (-2, 2):

2 = -5(-2) + b

2 = 10 + b

b = -8

This gives us the equation:

y = -5x -8

For the second problem, we can plug in the slope of 1 for m:

y = x + b

To solve for b, we plug in the given point (0, -2):

-2 = 0 + b

b = -2

This gives us the equation:

y = x - 2
