Answer:

x= -7

Step by Step Explanation:

We can write them both like functions like this

A= 5x- 4

B= 3x+ 8

The output of A will be three times the output of B

A=3b

We replace with the functions

5x-4= 3

We solve for x

5x= -4= 9x + 24

5x- 9x= 24 + 4

-4x= 28

x= 28 - 4

x= -7

The output that makes the out put of A 3 times the output of B is -7

Hope it helped

Answer:

=36\sqrt{7}i

Step-by-step explanation:

sqrt of 7-11=2i

simplify to 6\cdot \:2\sqrt{9}\sqrt{7}i

then sqrt of 9=3

then we simplify again to =36\sqrt{7}i

I need help algebra ​
asambeis [7]

Answer:

A. the slope value is 1/4

B. 0

C. y = 1/4x

Step-by-step explanation:

A: the slope can be calculated with the formula

m =  \frac{rise}{run}  = \frac{y2 - y1}{x2 - x1}

m is the slope

(x1, y1) is your first coordinate point (any point will work)

(x2, y2) is your second coordinate point (any point will work)

Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:

m =  \frac{y2 - y1}{x2 - x1}  =  \frac{1 - 0}{4 - 0}  =  \frac{1}{4}

B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.

C:

the equation of the graph is y = mx + b.

m is the slope = 1/4

b is the y-intercept = 0

Therefore the equation is y = 1/4x

Find a number that,if you add 4 to it,and multiply the answer by 3,and then subtract 4,will give you 65.
ikadub [295]
(x + 4)*3 - 4 = 65
3x + 12 - 4 = 65
3x = 65 - 12 + 4
3x = 57 |:3
x = 19 <-- Answer

(19+4)*3-4 = 23*3-4 = 69-4 = 65
