Answer:

y= -3x + 11

Step-by-step explanation:

Slope formula: y^2- y^1 divide by x^2- x^1

y^2 is -1

y^1 is 5

x^2 is 4

x^1 is 2

-1 - 5 = -6

4 - 2 = 2

-6/2 = - 3

Y-intercept: Using the slope and either of the two points, replace the y, m, and x in y= mx+b.

Using (2, 5)

5= -3(2) + b

5= -6 + b

Add 6 to both sides in order to eliminate -6.

-6 + 6 = 0

5 + 6 = 11

11 = b

Combine your slope-intercept formula:

y= 3x + 11

Solve the following equations 5^2x-2(5^x)-15=0

castortr0y [4]

Answer:

x = 1

Step-by-step explanation:

${5}^{2x} - 2( {5}^{x} ) - 15 = 0$

$( {5}^{x} {)}^{2} - 2 \times {5}^{x} - 15 = 0$

${t}^{2} - 2t - 15 = 0$

${5}^{x} t = - 3 \: \: .5$

${5}^{x} = 5$

$x = 1$

Someone can help me with 31 & 33? i need help

nika2105 [10]

31. It gives you the equation f(x) = -2x + 4 and asks you to solve for f(12). To solve this you must replace x in the equation -2x + 4 with 12 like so:

-2(12) + 4

Remember that when solving this use your rules of PEMDAS. In this case you will first multiply -2 and 12 then add the product with 4

-24 + 4

f(12) = -20

33. Replace x in the equation x³ - x with 5 like so...

5³ - 5

Again, remember to use the rules of PEMDAS to solve this. First take the cube of 5 then subtract 5 from the answer

125 - 5

g(5) = 120

Hope this helped!

Evaluate 0 ∫ ( 3^3 - 5^2) dx -2

Jobisdone [24]

3^3 = 27
5^2 = 25
27 - 25 = 2

integral of 2 = 2x

(2x) evaluated from -2 to 0
= (0) - (2(-2)) = -(-4) = 4

If you did not make any mistakes in typing your question
the answer would be 4
