Answer:

x = -26.67 (this is rounded the real answer is 26.6666...)

Step-by-step explanation:

180 - (46 + 36) = 82 (the measure of the last angle)

82 = (2 - 3x)

(subtract two from both sides)

80 = (-3x)

(divide both sides by -3)

-26.67=x

If you are single with no children, earn $36,000/year and set a savings goal of 5% per month, each month you should save _______

zimovet [89]

Answer:

Each month you should save $ 150

Step-by-step explanation:

First, the earnings are given per year, so we need to transform $36000/year into dollars per month. So, using a rule of three as following, we obtain:

$ 36,000 ------------- 12 months

X -------------- 1 month

Solving for X, we get:

$X=\frac{36000*1}{12}$

X = $ 3,000 /month

it means that earn $36,000/year is equivalent to earn $3,000/month

Now, we need to find the 5% of $3,000, this can be calculated making the following multiplication:

$3,000*\frac{5}{100} = 150$

Then, each month you should save $150

Help with those three please!!

Scilla [17]

Answer:

Part 1) Option A. The axis of symmetry is x=4

Part 2) Option C. minimum

Part 3) Option A. (4,-4)

Part 4) Option B. (2,0) and (6,0)

Step-by-step explanation:

we have

$f(x)=x^{2}-8x+12$

Part 1) What is the axis of symmetry of the parabola described by the equation above?

we know that

The equation above is a vertical parabola open upward

The axis of symmetry is the x-coordinate of the vertex

Find the vertex of the parabola (convert the equation in vertex form)

$f(x)-12=x^{2}-8x$

$f(x)-12+16=x^{2}-8x+16$

$f(x)+4=x^{2}-8x+16$

$f(x)+4=(x-4)^{2}$

$f(x)=(x-4)^{2}-4$ ----> equation in vertex form

The vertex of the parabola is (4,-4)

The axis of symmetry is x=4

Part 2) The vertex of the equation above is also

we know that

The equation above is a vertical parabola open upward

therefore

The vertex is a minimum

Part 3) What is the vertex of the parabola described by the equation above

we know that

The equation of the parabola into vertex form is equal to

$f(x)=(x-4)^{2}-4$

therefore

The vertex of the parabola is (4,-4)

Part 4) What are the x-intercepts of the parabola described by the equation above

we know that

The x-intercepts are the values of x when the value of y is equal to zero

$f(x)+4=(x-4)^{2}$

f)x)=0

$4=(x-4)^{2}$

take square root both sides

$(x-4)=(+/-)2$

$x=4(+/-)2$

$x=4(+)2=6$

$x=4(-)2=2$

therefore

The x-intercepts are

(2,0) and (6,0)
