Answer:

popcorn 3.29$

popcorn + 15 pack juice = 27.14$

Step-by-step explanation:

15 pack juice= 27.14-3.29

15 pack juice=23.85

pack of juice=23.85/15

pack of juice=1.59$

The equation that shows the cost of each bottle of juice is 15j + 3.29 = 27.14 and the cost of each juice is $1.59

An equation is an expression that shows the relationship between two or more numbers and variables.

Let j represent the cost of each bottle of juice. The total cost before tax was $27.14, hence:

15j + 3.29 = 27.14

j = 1.59

The equation that shows the cost of each bottle of juice is 15j + 3.29 = 27.14 and the cost of each juice is $1.59

Answer: 2

(-4, 0) and (0, 0)

Step-by-step explanation:

Answer:

Step-by-step explanation:

a)  Sum = - 6

Product = - 16

Factors = (-8) ; (2   {-8 + 2 = -6  ; (-8) * 2 = -16}

y = x² - 6x - 16

     = x²  + 2x - 8x - 16

     = x(x + 2) - 8(x + 2)

    = (x +2)(x -8)

b) y = 0

(x +2 )(x -8) = 0

x + 2 = 0  ;   x -  8 = 0

x = -2       ;  x = 8

(-2) ; 8 are the zeros.

Answer:

a) 4 to the 14th power

b) 12 to the 9th power

c) 5 to the 7th power

d) 7 to the 3rd power

Step-by-step explanation:

a) [tex]4^{6}[/tex] · [tex]4^{8}[/tex] equals 4 to the 14th power.

Using the Product Rule of Exponents:

[tex]a^{m} a^{n} = a^{m+n}[/tex]

You could add the exponents since they have the same base.  

b) [tex]12^{6}[/tex] · [tex]12^{3}[/tex]  equals 12 to the 9th power.

Same Product Rule applies as we did in problem a).

c) [tex]\frac{5^{10} }{5^{3} }[/tex]  equals 5 to the 7th power.

Using the Quotient Rule of Exponents:

[tex]\frac{a^{m} }{a^{n} } = a^{m - n}[/tex]

You'll have to subtract the exponents since they have the same base.

[tex]\frac{5^{10} }{5^{3} } = 5^{10 - 3} = 5^{7}[/tex]

d) [tex]\frac{7^{6} }{7^{3} }[/tex]  equals 7 to the 3rd power.

Same Quotient Rule applies as we did in problem c).

[tex]\frac{7^{6} }{7^{3} } = 7^{6 - 3} = 7^{3}[/tex]

Answer:

  m ≥ -√5

Step-by-step explanation:

If g(x) = f(|x|) for x∈i, then g(x) = f(x) for x∈ℝ: x ≥ 0.

f'(x) is 5th-degree, so f(x) is 6th-degree, meaning it is generally U-shaped. Since we're only concerned with x ≥ 0, we want to make sure f'(x) has no real zeros of odd multiplicity such that x > 0. The given factors of f'(x) make it have real zeros at x = -3 and x = -1.

For the last factor, (x² +2mx +5) to have no positive real zeros of odd multiplicity, we must have m ≥ 0 or the discriminant ≤ 0. The discriminant is ...

  d = b² -4ac = (2m)² -4(1)(5) = 4m² -20 . . . . . discriminant of the last factor

  d ≤ 0 . . . . . . . . . . the condition for no real zeros

  4m² -20 ≤ 0

  m² -5 ≤ 0 . . . . . . divide by 4

  m² ≤ 5 . . . . . . . . .add 5

  |m| ≤ √5 . . . . . . . take the square root

This tells us there will be a positive real zero of multiplicity 2 in f'(x) when m = -√5, and there will be no positive real zeros for -√5 < m < 0

There will be no odd-multiplicity positive real zeros in the derivative function f'(x) as long as m ≥ -√5. This means the slope of f(x) is non-negative for x ≥ 0, hence f(|x|) has its only minimum at x=0.

_____

Additional comment

The multiplicity of the zeros of f'(x) is important because the derivative will only change sign where the multiplicity is odd. When the discriminant of (x²+2mx+5) is zero, the associated positive real zero will have multiplicity 2, hence f'(x) will not change sign there.

Answer:

y = -x + 8

Step-by-step explanation:

In writing an equation of a line, keep in mind that you ALWAYS need the following information in order to establish a linear equation:

1. 2 ordered pairs (x,y) on the line

2. Slope

We'll use points (1, 7) and (0, 8).

Let (x1, y1) = (1, 7)

(x2, y2) = (0, 8)

Now that we have the two ordered pairs, substitute their values into the following slope formula:

m = (y2 - y1)/(x2 - x1)

m = (8 - 7) / (0 - 1)

m = 1 / -1 = -1

Therefore, the slope of the line, m =  -1.

Next, we need to determine the y-intercept, (b).  The y-intercept is the y-coordinate of the point (0, b ) where the graph crosses the y-axis. The y-intercept is also the value of y when x = 0. Looking at the graph, we can see that it crosses the y-axis at point (0, 8). We used this point earlier to solve for the slope. The y-intercept, b = 8.

Therefore, the linear equation in slope-intercept form is: y = -x + 8.

Answer:

y = –x + 8

Step-by-step explanation:

the line is negative and decreasing by –1/1 (rise over run is the slope). a slope of 1 can be represented by writing "x". in this case the slope is –x. the b in mx+b represents the y-value that the graph starts at. in this it starts at 8.

Step-by-step explanation:

when two lines are perpendicular to each other( the product of their slope; m1m2 = -1)

m1 = -1/m2

m1 = -1/-6= 1/6

using the formula m= y-y1 / x - x1

1/6 = y -7 /x - 3

6(y -7) = x -3

6y -42 = x - 3

6y - x -39 =0

Divide both sides by 6

y - 1/6 x - 13/2= 0

y = 1/6 x + 13/2

They must travel 125 miles farther before they stop for lunch and option A is the correct answer.

We have,

The total distance of the trip is 360 miles.

They plan to stop for lunch at the midpoint of the trip, which is

360 / 2 = 180 miles.

Now,

They have already travelled 55 miles this morning.

To find out how much farther they must travel before stopping for lunch, we subtract the distance travelled from the midpoint:

180 - 55

= 125 miles.

Thus,

They must travel A. 125 miles farther before they stop for lunch.

5x =41-6

5x=35

x=(35/5)

x=7

Step-by-step explanation:

if 2 sides are equal which means it is an Isosceles triangle

so,

→ 52 + 52 + c = 180

→ 104 + c = 180

→ c = 180 - 104

→ c = 76°

d = 52°

Step-by-step explanation:

Surface area, A, of a cylinder is given by the formula:

A = 2*pi*r*h + 2*pi*r²

r = radius

h = height

Substituting pi for 3.14 gives:

A = (2 * 3.14 * 4 * 7) + (2 * 3.14 * 4²)

A = 276.32cm³
