Answer:

Between (-6,0) and (-5,0).

Step-by-step explanation:

When it crosses the x axis, it's an x-intercept. To find the x-intercept, set y (aka f(x)) to zero. The solutions to the equation are approximately 3.36 and - 5.36. Since you're finding the negative x-intercept, you only need the negative solution - 5.36. This is in between (-6,0) and (-5,0).

0.5 grams of salt is equal to how many milligrams show you work
elena55 [62]

Answer:

500 milligrams (mg)

Step-by-step explanation:

1 Gram (g) is equal to 1000 milligrams (mg). To convert grams to milligrams, multiply the gram value by 1000. For example, to convert 2 grams to mg, multiply 2 by 1000, that makes 2000 mg is 2 grams.

Help me please I’m begging you:(
alex41 [277]

Answer:

Chips = 14

Pretzel = 14

Cookie = 8

Popcorn = 13

Question Mark = 222

Step-by-step explanation:

First Equation:

Chips + Pretzel + Chips = 42

Third Equation: Chips = Pretzel.

This means that

Pretzel + Pretzel + Pretzel = 42

Pretzel = \frac{42}{3} =14

Chips = Pretzel

Chips = 14

Second Equation:

Cookie + Chips + Cookie = 30

We know that Chips = 14.

Cookie + 14 + Cookie = 30

Subtract 14 on both sides:

Cookie + Cookie = 16

Cookie = 16\div 2 =8.

Fourth Equation:

Cookie + Cookie + Popcorn = 29

We know that Cookie = 8.

8 + 8 + Popcorn = 29

16 + Popcorn = 29

Subtract 16 on both sides:

Popcorn = 13.

Question Mark:

(Popcorn + Popcorn) \times Cookie + Chips = (13 + 13) \times 8 + 14 = 26 \times 8 + 14 = 208+14=222

X=7^y how can you rewrite this equation in y = form ?
Anuta_ua [19.1K]

Answer:

y = lnx / ln 7.

Step-by-step explanation:

x = 7^y

Take logarithms of both sides:

ln x = ln 7^y

ln x = y ln 7     ( because ln a^b = b ln a.   One of the Laws of Logarithms).

y = lnx / ln 7.
