Make the two equations equal together and solve for x
(x/3) = -2x+7 
multiple both sides by 3
x=-6x+21
solve for x
7x=21
x=3.
now plug in 3 into one of the equation to find your y value. 
y=-2(3)+7
y=1
write your answer as a coordinate; (3,1)

Mrs. Galicia has a cupcake company. The amount of money earned is represented by
sashaice [31]

Using the profit function, it is found that:

a) She earns $36 after 25 years.

b) The function was shifted right 4 units and up 1 units.

<h3>What is the profit function?</h3>

The profit, in x years after 2015, is given by:

p(x) = 12\sqrt[3]{x + 2}

Item a:

She earns $36 after x years, considering x for which p(x) = 36, hence:

p(x) = 12\sqrt[3]{x + 2}

36 = 12\sqrt[3]{x + 2}

\sqrt[3]{x + 2} = 3

(\sqrt[3]{x + 2})^3 = 3^3

x + 2 = 27

x = 25

She earns $36 after 25 years.

Item b:

The new function is:

h(x) = 12\sqrt[3]{x - 2} + 1

At the domain, we have that x + 2 \rightarrow x - 2, that is, x \rightarrow x - 4, hence it was shifted right 4 units.

At the range, we have that h(x) = h(x - 4) + 1, hence it was shifted up 1 unit.

USPshnik [31]

Answer: 2 kg

Step-by-step explanation:

3/4(22-x)=17-x

66/4-3/4x=34/2-x

33/2-3/4x=34/2-x

1/4x=1/2

x=2

The following graph shows a proportional relationship.
elena-s [515]

Answer:

The constant of proportionality is thus 1

Step-by-step explanation:

Note that the green line passes through (6, 6) and has a y-intercept of 0.  Thus, the equation of the line is y = (6/6)x + 0, or y = x, or y = 1x.

The constant of proportionality is thus 1, which is also the slope of this line.
