1.09  +

1.38

First, add the numbers in the hundredths column:

9+8=16

Carry the one, and add the numbers in the tenths column:

1+0+3=4

Now, add the numbers in the ones column:

1+1=2

Bring the decimal straight down.

The answer is 2.46

Hope this helps!!

Solve 16(t - 1) + 10 > 8(t + 2) + 4(t - 1) + 4t.
Neporo4naja [7]

Answer:

The answer to your question is it has no solution

Step-by-step explanation:

Inequality

                   16(t - 1) + 10 > 8(t + 2) + 4(t - 1) + 4t

-Expand

                   16t - 16 + 10 > 8t + 16 + 4t - 4 + 4t

- Group like terms

                   16t - 8t - 4t - 4t > 16 - 4 + 16 - 10

-Simplify

                                       0 > 18

- It has no solution because the variable is cancelled.

(ED. 21) Analytic Geometry Unit Test..... #3 Which point is a solution of x2 + y2 > 49 and y ≤ –x2 – 4?
sdas [7]

Answer:

We want to find a solution of the system:

x^2 + y^2 > 49

y ≤ –x^2 – 4

Here we do not have any options, so let's try to find a general solution.

First, we can remember that the equation of a circle centered in the point (a, b) and of radius R is:

(x - a)^2 + (y - b)^2 = R^2

If we look at our first inequality, we can write it as:

x^2 + y^2 > 7^2

So the solutions of the first inequality are all the points that are outside (because the symbol used is >) of the circle of radius R = 7 centered in the origin.

From the other equation, we would get:

y ≤ –x^2 – 4

This is parabola, anything that is in the graph of the parabola or below will be a solution for this inequality.

Then the solutions of the system, are the ones that are in the region of solutions for both inequalities.

You can see the graph below, where both regions are graphed. The intersection of these regions is the region of the solutions for the system of inequalities:

by looking at the graph, we can see a lot of points that are solutions, like:

(0, -10)

(0, -15)

(2, -10)

etc.

What is y=-4/3x +6. y=2
Mekhanik [1.2K]

The given equation is:
[/tex]y=-\frac{4}{3}x+6 [/tex] and we need to evaluate this for y=2.
So, first step is to plug in 2 for y in the above equation. Therefore,

2=-\frac{4}{3} x+6
2*3=-\frac{4}{3} x*3+6*3 Multiply each sides by common denominator 3
6=-4x+18
6-18= -4x Subtract 18 from each sides.
-12=-4x
-\frac{12}{-4} =-\frac{4x}{-4}
So, x=3

Evaluate the following expression. 3^-2
Crazy boy [7]

Answer: The simplified form is \frac{1}{9}

Step-by-step explanation:

Since we have given that

3^{-2}

As we know the  "Exponential law":

a^{-1}=\frac{1}{a^m}

So, it becomes

3^{-2}=\frac{1}{3^2}

Now, at last it becomes,

3^{-2}=\frac{1}{3\times 3}=\frac{1}{9}

Hence, the simplified form is \frac{1}{9}
