How do you find the slope of the points: (19,-16),(-7,-15)?

nirvana33 [79]

Answer:

$\Huge\boxed{\mathsf{\frac{1}{26} }}$

Step-by-step explanation:

<em><u>SLOPE FORMULA:</u></em>

$\longrightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1} }}$

Y₂=(-15)

Y₁=(-16)

X₂=(-7)

X₁=19

Solve.

$\displaystyle \mathsf{\frac{(-15)-(-16)}{(-7)-19}=\frac{(-15)+16}{(-7)-19}=\frac{1}{-26}=\boxed{\mathsf{\frac{1}{26}} } }}}}$

So, the slope is 1/26.

What is the solution to 3/4a>-16?

Georgia [21]

3/4a>-16
Multiply by the reciprocal of 3/4 on each side to get only a on one side of inequality.
a> -16 x (4/3)
That can be simplified to:
a > -64/3
a > -21 1/3

Hope this helps :)

Can someone please help me please

qwelly [4]

Answer:

$1) \dfrac{12+\sqrt{-16}}{4}=\dfrac{12+\sqrt{16i^{2}}}{4}\\\\\\=\dfrac{12+4i}{4}=\dfrac{12}{4}+\dfrac{4i}{4}\\\\\\= 3 + i$

Real part = 3 & imaginary part = 1

2) 4 + 7i - 8 = 4 -8 + 7i

= -4 + 7i

Real part = -4 & imaginary part = 7

$3)\dfrac{\sqrt{9}+\sqrt{-4}}{5}=\dfrac{3+\sqrt{4i^{2}}}{5}\\\\\\=\dfrac{3}{5}+\dfrac{2i}{5}\\\\\\Real \ part = \dfrac{3}{5} \ & \ imaginary \ part = \dfrac{2}{5}$

$4) -2-\sqrt{-25}=-2-\sqrt{25i^{2}}=-2-5i$

Real part = -2 & imaginary part = -5

$5)\dfrac{15-13i}{3}=\dfrac{15}{3}-\dfrac{13i}{3}\\\\\\Real \ part = \dfrac{15}{3} \ & \ imaginary \ part = \dfrac{-13}{3}$

b) 1) 6 + 4i

2) -12+ 5i

3) 5-14i
