Slope of (-7, -5) and (-7, -7)

Mathematics
1 answer:
Amiraneli [1.4K]3 years ago
5 0

Answer:

Infinity

Step-by-step explanation:

Slope or gradient is given as the ratio of change of y axis in respect to change in x axis. Therefore,

m=∆y÷∆x

Where ∆y in given by y2-y1 and ∆x is equal to x2-x1

Taking point 1 to be (-7, -5) while point 2 is (-7, -7) then

∆y=-7--5=-2

∆x=-7--7=0

Therefore, the gradient will be -2÷0

Any number divided by zero is infinite. Therefore, the slope of these two points is infinite.

Expand, answer should be a polynomial in standard form<br><br> (5a+2)(a+4)=
castortr0y [4]

Answer:

The standard form of the expression (5a+2)(a+4) is 5a^{2}  + 22 a + 8.

Step-by-step explanation:

Here, the given expression is (5a+2)(a+4).

Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)

= 5a^{2}  + 20 a + 2a + 8

=  5a^{2}  + 22 a + 8

or,  (5a+2)(a+4) = 5a^{2}  + 22 a + 8

Also,  Standard Quadratic form is ax^{2}  +  bx + c = 0

Hence, the standard form of (5a+2)(a+4) is 5a^{2}  + 22 a + 8.
