Answer 1

Answer:

Yes

Step-by-step explanation:

Angle sum property=180°

The first triangle = 105°+40° = 145°= 180-145=35

The second triangle = 105°+35°=140°=180-140=40

So both are same

Try to find the third angle in both triangles and if the angles of both triangles are same, it means the triangles are similar

3. Find the height of rectangle with area (2x^2-9x+9) ft^2 and width (2x-3) ft

Answers

Answer:

The height of the area is (x - 3) ft.

Step-by-step explanation:

You can do this a few ways.  You could use long division to divide the area by the width, or you could just factor the area, which is guaranteed to have the width as a factor, leaving you with the height.

Let's go with factoring, as that's probably what this question is intended as:

[tex]= \frac{2x^2 - 9x + 9}{2x - 3} \\\\= \frac{2x^2 - 6x - 3x + 9}{2x - 3} \\\\= \frac{2x(x - 3) - 3(x - 3)}{2x - 3} \\\\= \frac{(2x - 3)(x - 3)}{2x - 3} \\\\= x - 3[/tex]

(x-11)(x+4)=0

x= 11 or x= -4

Answer:

x = 11 or x = -4

Step-by-step explanation:

x^2 - 7x - 44 = 0

-11 + 4 = -7, -11 × 4 = -44

(x -11)(x + 4) = 0 or (x + 4)(x - 11) = 0 Both are same way: O

Answer:

yes , keiko is correct.

sin^(-1)x = -sin^1

Answer:

Keiko is wrong

Step-by-step explanation:

Keiko is incorrect

When n is positive, 1^n will always be 1

but........ (-1)^n will not always be -1

This is because there are parenthesis around -1

So n is even, then it will be 1 not -1

For example, n = 4

You will do -1 * -1 * -1 * -1 which is 1 not -1

but if n = 3

You will do -1 * -1 * -1 which is -1

Therefore, the second statement is incorrect resulting in Keiko being wrong

Answers

Answer:

ur answer should be C. But I'm not really sure..

The table in which y is a linear function of x is; Choice C

Linear functions

According to the question;

We are required to identify in what table y is a linear function of x.

The slope of a linear function is always constant.

Hence, By observing the table in Choice C;

Slope = (8-6)/(0-(-1)) = (10-8)/(1-0) = 2.

Hence, since slope of the function is constant, the required table is: Choice C.

Which of the following shapes is a convex nonagon?
OA)
OB)
OC)
OD)

Answers

Shape A is a convex nonagon

It is asking for a convex nonagon, not a convex polygon. So in this case we are looking for a shape with 9 straight lines and 9 angles. Which means we can cross A out.

Now we need to look at which nonagon is a convex nonagon which means that we are looking for the shape having only interior angles measuring less than 180°. So this means that B and D can be crossed out.

Thus, the answer is C.

In systems by substitution what is y=x+8 and x+y=2

Answers

Answer:

x = -3

Step-by-step explanation:

y = x + 8 and x + y = 2

Using substitution, we know that y = x + 8, so:

x + y = 2

x + (x + 8) = 2

2x + 8 = 2

2x = -6

x = -3

Then we solve for y:

x + y = 2

-3 + y = 2

y = 2 + 3

y = 5

Is it y=x ??

It's the first one. y can equal x as long as y doesn't equal x multiple times. We also know the last two are wrong because they're saying the same thing. A linear function is a straight line.
