For function one, the slope is already in mx+b form. The coefficient to x is the slope, so it is four in this case. For the second function we calculate the slope using rise over run. The rise is change in y and run is change in x, so 4/2= 2 slope. Four is greater than two so it has the greater rate of change. The answer is B

First function - y = 4x + 5
It is in the form mx + c

Slope ,m = 4

For second function
y - y1 / x - x1 = 10 - 6/ 3 -1 = 4/2 = 2
Slope = 2

So comparing them, the correct answer is B

Place the indicated product in the proper location on the grid (x+y+3)(x+y-4)
pashok25 [27]

Solution:

we have been asked to find the product of (x+y+3)(x+y-4).

we will multiply term by term as below

(x+y+3)(x+y-4)=x(x+y+3)+y(x+y+3)-4(x+y+3)\\\\\ (x+y+3)(x+y-4)=x^2+xy+3x+xy+y^2+3y-4x-4y-12\\\\\text{Now take the like terms together and simplify we get}\\\\(x+y+3)(x+y-4)=x^2+y^2+2xy-x-y-12\\

Hence the the product of (x+y+3)(x+y-4) is x^2+y^2+2xy-x-y-12

Can someone please help me with this
dedylja [7]

Step-by-step explanation:

WYXV is quadrilateral.

the reason are the undefined angles at W and V (they are equal, but not necessarily 90°, so the shape could shrink or extend between W and V)

ABCD is a rectangle.

AB and CD are parallel and equally long. and C is 90°.

that means then that the other angles must be 90° too, or either the parallel or equally long criteria would be violated.

PQSR is a parallelogram.

PQ and RS are parallel and equally long.

that means that PR and QS must also be parallel and equally long. we just don't know the angles, they could be anything. and therefore this is not a rectangle but a more generic parallelogram.

Are obtuse angles always, sometimes, or never equal to 180°? .always .sometimes .never
laila [671]
Salutations!

<span>Are obtuse angles always, sometimes, or never equal to 180°?

Obtuse angles are angles </span>whose measure is greater than 90° and less than 180°. Its not always the case that an obtuse angle should be exact 180 °. So I reckon t would be sometimes, as its not always 180 °. 

Hope I helped.
