REALLY NEED HELP: given that (-5,-2) is on the graph of f(x) find the corresponding point for the function 2f(x)

laiz [17]

we are given

point for f(x) is (-5,-2)

Whenever we need to find point for a*f(x) , we will multiply a by y-value

Here , we have 2f(x)

so, we will multiply 2 units to y-value

y-value is -2

new y-value will be 2*-2=-4

so,

point for 2f(x) will be (-5,-4)........Answer

-5x-4y=10

strojnjashka [21]

Answer:

y intercept = $(0, ~-\frac{5}{2} )$

x intercept = $(-2, ~0)$

Step-by-step explanation:

$-5x - 5y = 10$

y intercept

$\to x = 0$

$-5(0) - 4y = 10$

$-4y = 10$

$y = \frac{10}{-4}$

$y = -\frac{5}{2}$

so, the answer is $(0, ~-\frac{5}{2} )$

x intercept

$\to y = 0$

$-5x - 4(0) = 10$

$-5x = 10$

$x = \frac{10}{-5}$

$x = -2$

so, the answer is $(-2, ~0)$

Happy to help :)
