Answer:
equation for slope intercept form is
y-y1=m(x-x1)
where m is slope and (x1,y1) are coordinate points
here (-3,1) are points we take
y-1=m(x+3)
to find the value of m we know this line is parallel to line y=2x-4
here m=2
so put this m into first equation
y-1=2(x+3) (parallel lines have same slope)
this is the required equation y-1=2(x+3)
Answer:
2x + 2
Step-by-step explanation:
you multiply what's on the outside by the two terms that are inside of the parentheses.
Answer: It is 10 because there are 2 other faces and 8+2=10
Step-by-step explanation:
Answer:
(1) B. f(x)->0 as x->∞, f(x)->∞ as x->-∞
(2) D.
Step-by-step explanation:
. Given 0<b<1
'b' is between 0 and 1 so b should be a fraction
'b' is a fraction, so for positive value of x , the value of f(x) cannot be negative.
the graph of f(x) will goes close to 0 but it never cross x axis
So end behavior is f(x)->0 as x->∞
for negative values of x , the y value increases
So end behavior is f(x)->∞ as x->-∞
(2) f(x) = 2^x
When graph reflects across y axis, x becomes -x
so
For translating up by 5 units we add 5 at the end
so
Answer:
• the equation kind is incorrect
• the equation is incorrect
• the equation should be: y = 15/x
Step-by-step explanation:
We observe that the data tells us the time is inversely proportional to the number of workers, and that the product of time and workers is 15 worker·hours. The form for inverse proportionality is ...
y = k/x
or
xy = k
Our observation tells us k = 15 (worker·hours), so our model equation is ...
y = 15/x . . . . . where x is the number of workers, and y is the hours to paint the room
