PEASE HELP ASAP!!! The sum of two numbers is 58.

agasfer [191]

Answer:

y=15

x=43

(any variable can be used, I used x and y to make it easier to show)

Step-by-step explanation:

x+y=58

x-y=28

get x by its self

x=58-y

then subsitute into the other equation

(58-y)-y=28

58-2y=28

-2y=-30

y=15

sub. again

x+15=58

x=43

What is <br> the equation of the line that passes through the points (-6,6) and (-1,-9)

IgorLugansk [536]

Answer:

The answer to the question provided is y = -3x - 12.

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

$y = mx + b$

❃Incase you also forgot, what the slope formula is ☟

$m = \frac{y_2 - y_1 }{x_2 - x_1}$

➊ First: We are going to be solving for the slope.

$m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3$

➋Second: We find the y-intercept.

$y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{ - 18 = - 18 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 12 = b}$

➌Third: Plug in.

$y = - 3x - 12$

In a spreadsheet create a function that generates for any value x the corresponding value y when y = 10x 7. what is the value y

bezimeni [28]

The value of y when the value of x is 8 is 87

<h3>Function and values</h3>

Functions are equation expressed in terms of variables. Given the expression below;

y = 10x + 7

If the value of x is 8, then on substituting, we will have:

y = 10(8) + 7

y = 80 + 7

Simplify

y = 87

Hence the value of y when the value of x is 8 is 87

Solve the equation: <br><br> 9 (x − 9)−3 = −4 (2x + 4)<br><br> 4<br><br> -4<br><br> 100<br><br> 68

Nina [5.8K]

Answer:

Step-by-step explanation:

Applying BODMAS here;

We first solve what is in the brackets:

9x - 81 -3 = -8x - 16

We then put the like terms together:

9x + 8x = -16 + 81 + 3

We then do the addition:

17x = -16 + 84

We then do the subtraction:

17x = 68

Simplifying this gives:

x = $\frac{68}{17}$ = 4
