Answer:

y = x2 - 4x + 2 ; y=x²-4

Step-by-step explanation:

Axis of symmetry = - b /2a

y=x²-2

a = 1 ; b = - 2

x = - (-2) / 2(1)

x = 2/2 = 1

y = x2 - 4x + 2

a = 1 ; b = - 4

x = - (-4) / 2(1)

x = 4/2 = 2

y = x2 + 4x + 2

a = 1 ; b = 4

x = - 4 / 2(1)

x = - 4/2 = - 2

y=x²-4

a = 1 ; b = - 4

x = - (-4) / 2(1)

x = 4/2 = 2

Answer:

y = x2 - 4x + 2 ; y=x²-4

Answer:

Yes, I agree. Since the area of the piece of wood is greater than the area of the box she wants to make, then she has enough wood to make the box.

Step-by-step explanation:

First, we will calculate the area of the piece of wood Heather has

Area (A) = Length (l) × Width (w)

From the question, l = 14 inches and w = 13 inches

A = 14 inches × 13 inches

A = 182 squares inches

Hence, the area of the piece of wood is 182 square inches

Now, we will calculate the total surface area of the box she desires to make

Area (A) of a box is given by

A = 2lw + 2lh + 2wh

Where l is the length

w is the width and

h is the height

She wants to make a box with a height of 3 inches and bases measuring 6.5 inches by 6.5 inches.

i.e h = 3 inches, l = 6.5 inches and w = 6.5 inches

∴ A = 2(6.5×6.5) + 2(6.5×3) + 2(6.5×3)

A = 84.5 + 39 + 39

A = 162.5 square inches

Hence, the area of the box she wants to make is 162.5 square inches

Since the area of the piece of wood is greater than the area of the box she wants to make, then she has enough wood to make the box.

Answer:

  (x, y) = (7, 2 2/3)

Step-by-step explanation:

We can multiply the first equation by 2/5 to get ...

  8x -6y = 40

The second equation gives an expression for 6y that we can substitute.

  8x -(3x -5) = 40

  5x +5 = 40 . . . . . eliminate parentheses

  x +1 = 8 . . . . . . . .divide by 5

  x = 7 . . . . . . . . . .subtract 1

Using the second equation, we find ...

  3(7) -5 = 6y

  y = 16/6 = 2 2/3

The coordinates of the point of intersection are (x, y) = (7, 2 2/3).

Answer:

No

He ate only 25% from whole grains

He ate 5% less grams from his goal

Step-by-step explanation:

Osvoldo has a goal of getting at least 30, percent of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.

Did Osvoldo meet his goal? Why? , Osvoldo ate grams of whole grains than his goal.

Percent of whole grains ate = grams of whole grain / total carbohydrates) x 100

(55/220) x 100 = 25%

This is less than his goal of 30% by (30% - 25%) 5%

Answer:

No, Osvoldo 11 grams of whole grains less than his goal.

Step-by-step explanation:

30% x 220

30% = 30/100 = 30 ÷ 100

30 ÷ 100 = 0.3

0.3 x 220 = 66

66 - 51 = 11
