Answer:

C. It is shifted 4 units down.

Step-by-step explanation:

Shifted four units down. When a number is at the end of the equation, it means that that number shifts up or down depending on its sign.  

Answer:

It is shifted 4 units down

Step-by-step explanation:

When we have a function the constant number that is not multiplied by a variable, in this case, 4 in the first function, indicates where the function will intercept the y-axis, or when x is equal to 0.

In this case, we have two functions:

y = 5x^2 - 4, in which -4 is the constant that will determine where the function intercepts the y-axis. So if we say that we have x=0, then y=-4

In the second function we have:

y= 5x^2, this function is very similar but we don´t have another number after 5x^2, so we will have a similar graph but when x = 0 then y = 0.

So the first graph is shifted 4 units down. We can see this in the attachment.

It shifted 4 u it’s to the left

It is shifted 4 units to the left.

Determine the value (or values) of h such that the matrix: 2 - 3 h - 6 9 5 is the augmented matrix of a consistent linear system
Verizon [17]

Answer:

In order to have a consistent linear system represented by the augmented matrix:

\left[\begin{array}{ccc}2&-3&h\\-6&9&5\end{array}\right]

the value of h must be:

h=-\frac{5}{3}

Step-by-step explanation:

A system is consistent if it has a solution, this solution can be unique or a set of infinite solutions.  

First, you take the augmented matrix and find the equivalent row echelon form using Gaussian-Jordan elimination:

To do this, you have to multiply the 1st row by 3 and add it to the 2nd row, the resulting matrix is:

\left[\begin{array}{ccc}2&-3&h\\0&0&5+3h\end{array}\right]

Now, write the system of equations:

2x_1-3x_2=h\\0x_1+0x_2=5+3h

The only way this system has a solution is if 5+3h=0, then, to satisfy this, the value of h must be:

h=-\frac{5}{3}

Here are some numbers written in standard form. From these numbers write down/
ELEN [110]

Answer:

When we have a number like:

1.0x10^n

To rewrite this in standard form, we need to:

if n is positive, we move the decimal point n times to the right, adding zeros when necessary.

1.0x10^3

n = 3. then we add 3 zeros between the one and the decimal point, this is:

1.0x10^3 = 1000

if n< 0, then we move the decimal point n times to the left.

If we had:

1.0x10^-3

We move the decimal point 3 times to the left, adding zeros as this is needed.

1.0x10^-3 = 0.001

if n = 0, we have:

1.0x10^0 = 1.0

Now let's rewrite all the given numbers:

A) 3.4x10^-1  = 0.34

B) 1.36x10^6  = 1360000

C) 7.9x10^0  = 7.9

D) 2.4x10^5  = 240000

E) 5.21x10^-3  = 0.00521

F) 4.3x10^-2 = 0.043

Please help me solve this
Lelechka [254]

Answer:

The measure of angle x is 115 degrees

Step-by-step explanation:

Supplementary angles are angles which, when added together, equal 180 degrees. So, subtracting 65 from 180 would get you the answer(115).
