Answer:

Step 2

Step-by-step explanation:

From the original equation to step 1, 5x and 3 have been switched. This is the commutative property of addition.

From step 1 to step 2, 3 and -7 have been combined to make -4. This is not the addition property of equality; this is addition or simplification.

What is the slope of the line passing through the points (0,-5) and (4,2)?

alukav5142 [94]

Answer:

$\huge{ \boxed{ \tt{ \frac{ 7}{4} }}}$

Step-by-step explanation:

$\text{Let \: the \: points \: be \: A \: and \: B}$

$\sf{A \:( \: 0 \:, - 5 \: ) \longrightarrow{ \: (x1 \:, y1)}}$

$\sf{B(4 \:, 2) \: \longrightarrow{ \:( x2 \:, y2)}}$

$\underline{ \text{Finding \: the \: slope} }:$

$\boxed{ \sf{Slope = \frac{y2 - y1}{x2 - x1}}}$

$\sf{➳ \: Slope = \frac{2 - ( - 5)}{4 - 0}}$

$\sf{➳ \: Slope = \frac{ 2 + 5}{4} }$

$\sf{➳ \: Slope = \frac{7}{4} }$

K^2+8k-9=0 can you help me solve with showing work

givi [52]

Using the PSN method:

P = -9
S = 8
So N = 9,-1

Using 9 and -1 in the original equation gives:

$k^2+9k-k-9=0
\\k(k+9)-1(k+9)=0
\\(k-1)(k+9)

\\\\k=1,-9$
