Difference means subtract so since it’s 30 - -12 you change it to addition and -12 becomes 12

30 + 12 = 42

Tom wants to save at least $2000. He already got $375. Let x be the amount he still needs to save.

375 + x >= 2000
Subtract 375 from both sides
375 + x - 375 >= 2000 - 375
x >= 1625

So he still needs to save at least $1625.

Hope this helps! :)

Can someone please help i dont understand
Sloan [31]

Answer:

x = 12

Step-by-step explanation:

Angle 1 = 8x - 17

Angle 2 = 5x + 19

These are congruent which means they are the same so the equation is:

8x - 17 = 5x + 19

3x - 17 = 19

3x = 36

x = 12

Given f(x)=3^(x-2) and g(x)=f(3x)+4, write the function rule for function g and describe the types of transformations that occur
klio [65]

Answer with Step-by-step explanation:

We are given that

f(x)=3^{x-2}

g(x)=f(3x)+4

We have to write the rule for function g and describe the transformation between f and g.

Compress the function by scale factor 3 and the translation rule is given by

(x,y)\rightarrow (3x,y)

Then, we get h(x)=f(3x)=3^{3x-2}

Now, shift the y coordinate 4 units above the origin.

Then, the translation rule is given by

(x,y)\rightarrow (x,y+4)

Then , we get

g(x)=3^{3x-2}+4
