Because log3(2)=x is not the same as 3^x=2 and log2(3) = x is 2^x=3 because in 2^x=3 x has to be greater than 1 to make 2 bigger, while in 3^x=2 x has to be smaller than 1 to make x smaller.

What is the slope of the line that passes through the points (-9, 2)(−9,2) and (1, 27) ?(1,27)? Write your answer in simplest fo

Cloud [144]

Answer:

pls mark brainliest if possible:

slope is 1.5

Step-by-step explanation:

Slope = rise over run = (y2-y1)/(x2-x1)

choose y2 and corresponding x-coordinate is x2. If we choose 27 as y2, then:

x2 = 1

x1 = -9

y1 = 2

then plug everything into the equation

(27-2)/(1-(-9))

=15/10

= 1.5

slope is 1.5

hope this helps!

From the sum of (3x2-4y2+5x) and (5-4x+2x2) subtract the sum of (-x2+2x-5) and (3y2-3x-3)

Varvara68 [4.7K]

Answer and Step-by-step explanation:

Simply add the expression together, then subtract the sum of the other expression

$6x^{2} - 7y^{2} + 2x + 13$ is the answer.

$3x^{2} - 4y^{2} + 5x + (5 - 4x + 2x^{2} )\\\\5x^{2} - 4y^{2} + x + 5\\\\\\-x^{2} + 2x - 5 + (3y^{2} - 3x - 3)\\\\\\-x^{2} + 3y^{2} - x - 8\\\\\\5x^{2} - 4y^{2} + x + 5 - (-x^{2} + 3y^{2} - x - 8)\\\\\\\\\\5x^{2} - 4y^{2} + x + 5 + x^{2} - 3y^{2} + x + 8\\\\\\\\\\\\6x^{2} - 7y^{2} + 2x + 13$
