Maru [420]2 years ago
4 0

Answer:

No

Step-by-step explanation:

The variables are different in both problems. In 2×+7=27, it's 10, while in the other problem, it's 9.

27 doesn't equal 28.

A tangent to the curve y=6x-x² cuts the x axis at point P. Find the coordinates of P. Help me calc the coordinates please​
Ilya [14]

We know that the line is tangent at the point (2,8)

The derivative of the function at x=2 is

f'(x) = 6-2x \implies f'(2) = 6-4=2

So, the tangent line passes through the point (2,8) and has slope 2. The equation is

y-8 = 2(x-2) \iff y = 2x+4

This line crosses the x axis where y=0:

0 = 2x+4 \iff 2x = -4 \iff x = -2

Is this triangle a right triangle? yes or no?
svlad2 [7]

Answer:

Yes.

Step-by-step explanation:

You can use the Pythagorean theorem to figure this out.

5²+12²=13²

25+144=169

169=169

You can also look at the bottom left corner, which is a right angle. All triangles containing right angles are right triangles.

You can also base your answer off of the fact that triangles are kind of like <u>G</u>oogle: They're always right. (jk no that's not true neither are always right)

Solving special systems.
irinina [24]

Given:

The equations of system of equations are

y=-4x-6

-4x-y-6=0

To find:

The solution of given system of equations.

Solution:

We have,

y=-4x-6         ...(i)

-4x-y-6=0         ...(ii)

Adding y on both sides in (ii), we get

-4x-6=y

y=-4x-6

It is same as equation (i). So, we can say that equation (i) and (ii) represent the same line or they are coincident.

Thus, the system of equations has infinitely many solutions.

Therefore, the correct option is C.
