45L + 30D = 360 ...reduce by dividing by 15 = 3L + 2D = 24
65L + 35D = 470...reduce by dividing by 5 = 13L + 7D = 94

3L + 2D = 24......multiply by 7
13L + 7D = 94...multiply by -2
------------------
21L + 14D = 168 (result of multiplying by 7)
-26L - 14D = - 188 (result of multiplying by -2)
-----------------add
-5L = - 20
L = -20/-5
L = 4

3L + 2D = 24
3(4) + 2D = 24
12 + 2D = 24
2D = 24 - 12
2D = 12
D = 12/2
D = 6

so the loaves of bread (L) cost $ 4 per loaf and the buns (D) cost $ 6 per dozen

Which graph matches the equation y+3=2(x+3)?
Vlad1618 [11]

Answer:

The graph that includes points (-3,-3) and (0,3)

Step-by-step explanation:

In the pictures attached, the options are shown.

The equation:

y+3=2(x+3)

has the point-slope form, which is:

y-y₁=m(x-x₁)

where (x₁, y₁) is a point on the line and <em>m</em> is its slope. This means that (-3,-3) is on the line. To know the y-intercept of the line, we have to replace x = 0 into the equation, as follows:

y+3=2(0+3)

y+3 = 6

y = 6 - 3

y = 3

Then, point (0, 3) is on the line.

Calculate cos theta to two decimal places. <br><br> A. 0.69<br> B. 1.38<br> C. -0.07<br> D. 0.77
alexgriva [62]

Answer:

A. 0.69

Step-by-step explanation:

We need to use cosine theorem:

c²=a²+b² - 2ab* cos(θ)

c=8, a=7, b=11

8² = 7²+11² - 2*7*11 *cos(θ)

64 = 49 + 121 - 154*cos(θ)

64 - 170 = - 154*cos(θ)

- 106/ (- 154) = cos(θ)

cos(θ) = 0.69
