Answer: x= -5/4, -1/2

Step-by-step explanation:

10x^2+15x-9=2x^2+x-14

- Move all terms to one side.

10x^2+15x−9− $2x^{2}$ −x+14=0

- Simplify 10x^2+15x−9− $2x^{2}$ −x+14 to 8x^2+14x+5.

8x^2+14x+5.

- Split the second term in 8x^2+14x+5 into two terms.

$8x^{2}+10x+4x+5=0$

- Factor out common terms in the first two terms, then in the last two terms.

2x(4x+5)+(4x+5)=0

- Factor out the common term 4x+5.

(4x+5)(2x+1)=0

- Solve for x.

x= -5/4, -1/2

Hope this helps, have a BLESSED and wonderful day, as well as a safe one! Also, hope your having a good 2020 :-)

Find the slope and y-intercept of -x + 2y = 3. I need help on working this problem out

natita [175]

Answer:

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$

Step-by-step explanation:

A first order function has the following format:

$y = ax + b$

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.

We have the following equation:

$-x + 2y = 3$

We just have to rewrite this equation

$2y = x + 3$

$y = \frac{x+3}{2}$

$y = \frac{x}{2} + \frac{3}{2}$

Which means that

$a = \frac{1}{2}, b = \frac{3}{2}$

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$

I’m Atlanta, the tax on a property assessed at $930,000 is $19,530. If tax rates are proportional in this city, how much would t

igomit [66]

Answer:

The tax on property assessed at $660,000 is $13860 .

Step-by-step explanation:

Given:

In Atlanta the tax on a property assessed at $930,000 is $19,530.

The tax rates are proportional to this city.

Now, to find the tax on a property assessed at $660,000.

So, we need to get the tax rate of Atlanta first.

Tax Rate = Tax / Property assessed × 100.

$Tax\ rate=\frac{19530}{930000} \times 100$

$Tax\ rate=0.021 \times 100$

$Tax\ rate=2.1\%$

According to question the tax rates are proportional.

So, for getting the tax in this city we use the same rate of Atlanta:

Tax = tax rate of property assessed.

$Tax = 2.1\% of\ \$660,000$

$Tax = \frac{2.1}{100}\times 660000.$

$Tax = 0.021\times 660000$

$Tax=\$13860$

Therefore, the tax on property assessed at $660,000 is $13860.

An Aibo costs $2,899.99. This includes a toy ball, a charging station, and several years of AI cloud service, which helps it lea

ivann1987 [24]

Answer:

See Below

Step-by-step explanation:

The attached graph shows the cumulative costs of owning an AIBO.

$2899.99 (about $2900) includes fixed cost of Toy Ball, Charging Station

Several years of AI cloud service is a variable cost because this is changing and it helps the robot dog "learn". It is going to cost after some time. But how long?

Looking at the cost of an AIBO, we see that until 3 years, the cost line is veyr close to 3000 dollars, we can say 2899.99 dollars. After 3 years, the cost rises with a slope. Now, this is the cost of AI cloud service being IMPOSED after first 3 years of being "free".

Thus,

We can say that service is free for first 3 years. We know by looking at the graph shown.
