Solve the two-step equation. -9x + 0.4 = 4

1 answer:

3 0

Hmm ok what thw answer would be is x=-0.4
Since you subtract 0.4 from both sides end up with -9x=3.6 and then divide -9 on both sides -9x/-9 cancel and 3.6/-9 and end up with x=0.4 hope this helped

Given the functions f(x)=1x−3+1 and g(x)=1x+4+3 .

SVETLANKA909090 [29]

Answer:

The graph shifts 7 units left and 2 units up.

Step-by-step explanation:

In transformations, when a number is added or subtracted to "x" directly, that is the left/right shift.

When a number is added or subtracted outside of the "rest" of the equation, that is the up/down shift.

I learned transformations with these variables:

$f(x) = \frac{a}{k(x-c)} + d$

"a" - vertical stretch (a > 1) or compression (0 < a < 1)

"k" - horizontal stretch (0 < k < 1) or compression (k > 1)

"c" - translate left (+) or right (-)

"d" - translation up (+) or down (-)

The untranslated graph is centred around the origin f(x) = 1/x

f(x) begins 3 units right and 1 unit up of the untranslated graph.

g(x) is 4 units left and 3 units up of the untranslated graph.

g |

| f

-----------|------------ x

There is a 7 units translation left and 2 units translation up.

3 out of 5 picks are orange. If 12 picks are orange, has many picks are there in all.

hodyreva [135]

If 3 out of 5 are oranges, this means the ratio is 3 oranges for every 5 total.

If there are 12 oranges, this is 4 groups of 3 oranges. You will need 4 groups of 5 total to make it equivalent.

4 x 5 = 20 total fruit.

3 x 4 = 12
5 x 4 20

In Mr. Harold's class there are 12 students. They each have 5 pencils. Some of the students, s, each lost 2 pencils. Now, the st

Katena32 [7]

The answer would be C. (12 x 5) - (s x 2) = 38.

This is because if there are 12 students with 5 pencils per student, we can say 12 x 5. Then, think of the phrase, two pencils lost per student. That would be 2s, or (s x 2). Since it’s lost, we would subtract that amount from 12 x 5.
