The value of c must be greater than 0 1 3 7
Answers
The true statement about the triangle is the value of c must be greater than 3.
How to complete the statementThe figure that completes the question is added as an attachment
From the figure, we have the following parameters
The length of segment AB is 12 units.The length of segment AC is 15 units.The length of segment of BC is represented by the variable c
By the triangle inequality theorem, we have:
The sum of any two sides length is greater than the third length
This means that
12 + 15 > c
c < 27
Also, we have
15 + c > 12
c >-3
Lastly, we have
12 + c > 15
c >3
Using the list of options as a guide, we have x > 3 to be true

This is for a test review I need help with. Which graph matches the quadratic equation
Answers
Okay, here we have this:
Considering the provided equation, we are going to identify which graph matches the quadratic equation, so we obtain the following:
To do this, then first we will identify which direction the parabola opens and what its center is, from there we will be able to identify the correct graph, then we have:
Then let us remember that the vertex of the parabola of the form y=ax^2+bx+c in its x coordinate is equal to -b/2a, applying:
[tex]x_v=-\frac{2}{2(-1)}=\frac{-2}{-2}=1[/tex]And replacing with this value in the function:
[tex]\begin{gathered} f(x)=-x^2+2x \\ f(1)=-1^2+2(1) \\ f(1)=-1+2 \\ f(1)=1 \end{gathered}[/tex]Finally we obtain that the vertex of the function is (1, 1).
According to the vertex finally found, we obtain that the correct option is option D, since it is the only graph that has the vertex of the function located at this point.

In the second step, 8x was subtracted from both sides of the equation. This should give us

Given that,
5.2187 x 10^−3, 2.05 x 10^7, and 3.40 x 10^3 multiply all the terms.
We have to find how many digits should be significant for the product.
Multiplication is the action of adding a number to itself for the specified number of times. For instance, 3 × 4 denotes the addition of 3 to itself 4 times, and the opposite is true for the other number.
The multiplication of the given numbers is
=5.1287 × 10⁻³ × 2.05 × 10⁷ × 3.40 × 10³
=5.1287 × 2.05 × 3.40 × 10⁽⁻³⁺⁷⁺³⁾
= 35.747039 × 10⁽⁻³⁺⁷⁺³⁾
= 35.747039 × 10⁷
= 3.5747 × 10⁸
Given that the digit "3" comes before the decimal and the number "10" has a power of 8. As a result, there are 9 significant digits in total (8 + 1).

in your own words, explain how you know that equations 2x + 2 = 8 and 2x = 6 are the same and have the same solution
Answers
You have the following equations:
2x + 2 = 8
2x = 6
The previous equations are the same equation because you can subtract 2 both sides of the first equation, and in such a way you obtain the second equation. In fat, you have:
2x + 2 = 8 subtract 2 both sides
2x = 8 - 2
2x = 6
which is exactly the same second equation. This situation is enough to prove that both equations are equal and then have the same siolutions.

find the slope and the y intercept y=5x-3what is the slope what is the y intercept
Answers
The y-intercept is the point where the graph of the equation crosses the y-axis. This happens when x = 0. If we replace x = 0 into the equation we get the y-intercept:
[tex]\begin{gathered} y=5x-3 \\ x=0 \\ y=-3 \end{gathered}[/tex]The y-intercept is -3
Then, this equation is written in the slope-intercept form. The general form is:
[tex]y=ax+b[/tex]Where b is the y-intercept and a is the slope. If we look at the equation and compare it to the general form we can see that a = 5 and b = -3 (b is the same value we obtained before for the y-intercept)
So, the slope is 5.
The slope is the variation of y respect of x
