Answer:

When solving -7y > 161 your symbol will be flipped when you divide by -7 and the number will be negative. Normally you would want to have a negative variable

when solving a inequality.

In 7y > -161 the symbol will not be flipped and the number will be negative.

The difference between both equations is if y is less than or greater.

Answer:

The inequalities would be different. One would be less than and the other would be greater than.

Step-by-step explanation:

The main differences between them is that the solutions that you would end up with with be completely different when you solve them.

Work:

-7y > 161\\\\\text{The variable (y) can't be negative, so you would divide -7 on both sides}\\\text{Since you're diving by a negative, the}\, (>)\text{ would flip.}\\\\y -161\\\\\text{In this one, you would just divide by 7}\\\\y>-23

They both get -23, but the inequalities would be different.

andreev551 [17]

Answer:

Slope : The rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.

T-intercept : 8.5 represents the temperature in °C of the earth's surface in the year 1900.

Step-by-step explanation:

The average surface temperature of Earth rising steadily. Scientists have modeled the temperature by the equation, T = 0.02t + 8.50 where t represents years since 1900 and T is the temperature in ◦C.

Now, the slope of the model equation is 0.02 which means the rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.

Again, the T-intercept i.e. 8.5 represents the temperature in °C of the earth's surface in the year 1900. (Answer)

If g (x) = 2x + 2, find g (a + h) - g <br> a. .<br> a. 2h<br> b. 2h + 4<br> c. h + 2
katrin [286]
G(x) = 2x + 2

g(a + h) - g(a) = 2(a+h) + 2 - (2(a) + 2)

g(a + h) - g(a) = 2a + 2h + 2 - 2a - 2

g(a + h) - g(a) = 2h + 2 - 2

g(a + h) - g(a) = 2h


Your final answer is a. 2h.

Josie is training for a race the ratio of the number of minutes she wants to the number of miles she wants is 2043 she plans to
guajiro [1.7K]

Answer:

Josie takes 0.93 minutes to run 2 miles.

Step-by-step explanation:

We are given the following in the question:

Ratio:

Number of minutes: Number of miles = 20:43

Josie wants to run 2 miles. We have to find the number of minutes she need to run to maintain the ration.

Let x be the number of minutes Josie run.

This can be done in the following manner:

\dfrac{20}{43} = \dfrac{x}{2}\\\\\Rightarrow x = \dfrac{20}{43}\times 2\\\\\Rightarrow x = 0.93

Thus, Josie takes 0.93 minutes to run 2 miles.

Simplify the expression.
Anna71 [15]

Since we have a cubic root, we're interested in factoring cubes inside the root, so that we can take them out. If we factor 648, we have

648=2^3\times 3^4=2^3\times 3^3\times 3 = (2\times 3)^3\times 3 = 3\times 6^3

So, we have

3x\sqrt[3]{648 x^4 y^8} = \sqrt[3]{3\times 6^3\cdot x^3\cdot x \cdot y^6\cdot y^2}=3x\cdot 6\cdot x\cdot y^2\sqrt[3]{3\cdot x\cdot y^2}

And the result simplifies to

18x^2y^2\sqrt[3]{3xy^2}
