Answer: The slope is undefined

Step-by-step explanation:

The slope of a line is calculated using the formula :

m = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$x_{1}$ = -7

$x_{2}$ = -7

$y_{1}$ = -7

$y_{2}$ = 1

Substituting the values into the formula , we have :

m = $\frac{1-(-7)}{-7-(-7)}$

m = $\frac{8}{0}$

m = undefined

Step-by-step explanation:

$2.\\(a-b)^2=a^2-2ab+b^2\\\\x^2-16x=-8\\\\x^2-2(x)(8)=-8\\\\\text{We have}\ 2ab=2(x)(8).\ \text{Therefore}\ b=8.\\\\x^2-2(x)(8)=-8\qquad\text{add}\ 8^2=64\ \text{to both sides}\\\\x^2-2(x)(8)+8^2=-8+64\\\\(x-8)^2=56$

$5.\\2x^2+x-1=2\qquad\text{subtract 2 from both sides}\\\\2x^2+x-3=0\\\\2x^2+3x-2x-3=0\\\\x(2x+3)-1(2x+3)=0\\\\(2x+3)(x-1)=0\iff 2x+3=0\ \vee\ x-1=0\\\\2x+3=0\qquad\text{subtract 3 from both sides}\\2x=-3\qquad\text{divide both sides by 2}\\\boxed{x=-\dfrac{3}{2}}\\\\x-1=0\qquad\text{add 1 to both sides}\\\boxed{x=1}$

$6.\\2x^2-4x=0\qquad\text{divide both sides by 2}\\\\x^2-2x=0\\\\x(x-2)=0\iff x=0\ \vee\ x-2=0\\\\\boxed{x=0}\\\\x-2=0\qquad\text{add 2 to both sides}\\\boxed{x=2}$

Given the slope of the line containing the points (-3,1) and (a,-14) is -5/3, find the value of a.

satela [25.4K]

Answer:

a=6

Step-by-step explanation:

write the equation as y=mx+b

y=-5/3x+b

solve for b

1=-5/3*-3+b

1-5=b

b=-4

Plug in -14 and solve for x

-14=-5/3x-4

-10=-5/3x

30/5=x

x=6 (x is basically a because a is the x coordinate)

What is 2.01 times ten to the fifth power into standard form

disa [49]

Since, you're moving up in exponents, you will move right the number of decimal spaces equivalent to the power of the exponent. Hence, move the decimal point five spaces to the right. There, you now have your answer. :)
