Answer:

The correct option is 3.

Step-by-step explanation:

If a line passes through to points $(x_1,y_1)$ and $(y_1,y_2)$ , then the slope of line is

$m=\frac{y_2-y_1}{x_2-x_1}$

Given points are (4,-7) and (6,3).

The slope between given points is

$m=\frac{3-(-7)}{6-4}$

$m=\frac{3+7}{2}$

On further simplification we get

$m=\frac{10}{2}$

$m=5$

Therefore the correct option is 3.

Help plssssssssssssssssssss

Answer: -74

Step-by-step explanation:

First you have to solve - 2y - 9 = 7 to find what "y" equals so we can plug that into 9y - 2

1. Solve -2y - 9 =7:

-2y = 16

y = -8

2. Plug -8 into the expression 9y - 2:

9(-8) - 2

-72 -2

-74!

Im sorry if i didnt do this correctly :/

4. solve<br> e) 4^x-10.2^x+16=0<br> I think the dot means multiply?

suter [353]

$4^x-10\cdot2^x+16=0\Rightarrow(2^2)^x-10\cdot2^x+16=0\Rightarrow(2^x)^2-10\cdot2^x+16=0$

$subtitute\ 2^x=t > 0\\\\t^2-10t+16=0\\t^2-2t-8t+16=0\\t(t-2)-8(t-2)=0\\(t-2)(t-8)=0\iff t-2=0\ or\ t-8=0\\\\t=2\ or\ t=8\\\\t=2^1\ or\ t=2^3\\\\therefore\ 2^x=2^1\ or\ 2^x=2^3\\\\Answer:\boxed{x=1\ or\ x=3}$
