Y-intercept = (0, 2)
slope = -3/7 what is the equation?

Answers

Answer:

y = -(3/7)x + 2

Step-by-step explanation:

(see attached)

recall that the slope-intercept form of a linear equation is

y = mx + b

where m = slope = given as -(3/7)

and b = y-intercept = 2

substituting these values into the eqation:

y = mx + b

y = -(3/7)x + 2

1 pint is equal to 16 ounces.
You need to know how many pints in 445 ounces.

1 pint x pints
-------------- = ----------------
16 ounces 445 ounces

You can cross multiply.
1*445 = 16x
445 = 16x

Divide by 16 on both sides.
27.8125

27.8125 pints

Hugh made a recipe that yields 8 and 1 over 2 cups. If each serving is 1 over 4 cup, which expression will help Hugh determine the number of servings his recipe will yield?8 and 1 over 2 • 1 over 4
8 and 1 over 2 + 1 over 4
8 and 1 over 2 – 1 over 4
8 and 1 over 2 ÷ 1 over 4
explain this please

Answers

Answer:

Its D, 8 and 1 over 2 ÷ 1 over 4

Step-by-step explanation:

→ A recipe yields = 8(1/2) cups.

And,

→ Each serving is = (1/4) cups.

So,

→ The number of servings his recipe will yield = (Total recipe yields) ÷ (Each serving) = 8(1/2) ÷ (1/4) = 8 and 1 over 2 ÷ 1 over 4 (Option D).

Answer:

The answer is D.

I need help is it A B C or D

Answers

I believe the answer is B.
To be parallel the lines must have the same gradient (which in this question is 2). The answer must either be B or D.

To find the correct one you can substitute in the value of X and see which gives the value of Y we are looking for.

Equation B:
y=2x+5
=2×3+5
=6+5
=11

Equation D:
y=2x-19
=2×3-19
=6-19
=-13

We are looking for a value of 11 so B is correct.

Yes i agree B. y=2x+5, is the correct answer

What are rational and irrational numbers ?

Answers

Rational: Any number that can be expressed as a fraction (or a ratio.)
Irrational: Not rational, any number that can't be written down as a fraction. Some examples include $\pi (3.1415926...)$ , $√(2)$ , and so on.

Anything rational can be expressed in a form other than a symbol. However, irrational numbers are those that go on forever and never stops, such as $\pi$ or phi
