1 answer:
Rasek [7]3 years ago
7 0

Answer:

Step-by-step explanation:

P(x) = (x² - 5x + 6 )( x² - 5x + 7 )

x² - 5x + 6 = ( x - 2 )( x - 3 )

Function y = x² - 5x + 7 > 0 ⇒ does not have any zeros ⇒

Zeros of P(x) are 2 and 3

Chef needs to prepare 32 Servings of cooked beans, each portion 3 oz. How 29. any 12 oz. cans should Chef order, if the Yield fa
Rus_ich [418]

Answer:

10 cans

Step-by-step explanation:

Number of servings to be prepared = 32

Weight of each pound = 3 oz

Yield factor per can = 0.8

Now,

Total weight of the cans = 32 × 3 = 96 oz

Actual weight required with yield factor 0.8 = \frac{96\ oz}{0.8} =  120 oz

Therefore,

The number of 12 oz cans required = \frac{120}{12}  = 10 cans

Which operation should you perform first when simplify you 75-(8+45/3) *7?
KonstantinChe [14]
According to PEMDAS, you should do the parenthesis first, then the multiplication, then the subtraction. Let's do it:
75-(8+45/3)*7
= 75-(8+15)*7
= 75- 23*7
= 75- 161
= -86.

Hope this helps~

Answer:

  1. AC is congruent to CE
  2. BG is congruent to DG
  3. BH is congruent to DF

Step-by-step explanation:

AC is congruent to CE because of the 2 congruent tick marks.

BG is congruent to DG because of the 1 congruent tick mark for each segment.

BH is congruent to DF because of the 3 congruent tick marks for each segment.

Consider the line y = - 4x +8.
Damm [24]

Answer:

The equation for the parallel line is: y = -4x - 20

The equation for the perpendicular line is: y = 1/4x + 11/2

Step-by-step explanation:

The given point is: (-6, 4)

The given equation is:

y = -4x + 8, note the slope m = -4.

A parallel line has the same slope. Use the point slope and substitute:

y - y1 = m(x - x1)

y - 4 = -4(x - (-6))

y - 4 = -4(x + 6)

y - 4 = -4x - 24

y = -4x - 20

Proof - find f(x) when x = -6:

f(x) = -4x - 20

f(-6) = -4(-6) - 20

f(-6) = 24 - 20 = 4, so the point is (-6, 4)

A perpendicular line has a slope that is negative and inverted so m = 1/4.

y - y1 = m(x - x1)

y - 4 = 1/4(x - (-6))

y - 4 = 1/4(x + 6)

y - 4 = 1/4x + 6/4

y - 4 = 1/4x + 3/2

y = 1/4x + 3/2 + 4

y = 1/4x + 3/2 + 8/2

y = 1/4x + 11/2

Proof - find f(x) when x = -6:

f(x) = 1/4x + 11/2

f(-6) = 1/4(-6) + 11/2

= -6/4 + 11/2

= -3/2 + 11/2

= 8/2 = 4, giving the point (-6, 4)
