Whenever you multiply or divide a negative number to both sides, you flip the sign

ex.
if you have x>1, and multiply -1 to both sides, then -x <-1

in your case, the best way to remove the -2 from the denominator would be to multiply -2 to both sides. Since you multiplied by a negative number, you need to switch the sign from < to >

Which function corresponds to the table of inputs and outputs?

Anarel [89]

Answer:

f(x) = 3x + 2

Step-by-step explanation:

That's easy to find out. You have your input number, which is your x value, and you have your output number which is your y value (or f(x)).

All you have to do is see if each of the proposed answer works for ALL entries in the data set.

f(x) = 3x + 2

for x = 3 ===> 11 = 3 (3) + 2 = 11 YES

for x = 5 ===> 17 = 3 (5) + 2 = 17 YES

for x = 7 ===> 23 = 3 (7) + 2 = 23 YES

for x = 9 ===> 29 = 3 (9) + 2 = 29 YES

f(x) = 2x + 5

for x = 3 ===> 11 = 2 (3) + 5 = 11 YES

for x = 5 ===> 17 = 2 (5) + 5 = 15 NO - we stop here for this function

f(x) = x + 7

for x = 3 ===> 11 = (3) + 7 = 10 NO - we stop here for this function

f(x) = 3x + 1

for x = 3 ===> 11 = 3 (3) + 1 = 10 NO - we stop here for this function

Indicate the equation of the given line in standard form.

Lorico [155]

We have that
triangle ABC
where
A(-5, 5), B(1, 1), and C(3, 4) are the vertices

using a graph tool
see the attached figure

the hypotenuse is the segment AC

find the equation of the line AC
A(-5, 5) C(3, 4)

step 1
find the slope m
m=(y2-y1)/(x2-x1)-----> m=(4-5)/(3+5)-----> m=-1/8

step 2
with C(3,4) and m=-1/8
find the equation of a line
y-y1=m*(x-x1)-----> y-4=(-1/8)*(x-3)----> y=(-1/8)*x+(3/8)+4
y=(-1/8)*x+(3/8)+4----> multiply by 8----> 8y=-x+3+32
8y=-x+35
the standard form is Ax+By=C
so
x+8y=35
A=1
B=8
C=35

the answer is
x+8y=35
