Snowcat [4.5K]

To find f(4) ( which means ' the value of f(x) when x = 4) we replace x by 4 then simplify:-

f(4) = 4*4 + 7

= 16 + 7

= 23 (answer).

Use the graph below to fill in the blank with the correct number:<br><br> f(1) = _______

algol13

F(1)= -2

Remember that when dealing with functions, it is written in the form of f(x). In this case, the x= 1, so its asking for the y value when x=1.

Please help me with this problem:Which properties justify the steps taken to solve the system?{2x−4y=183x+3y=0Drag and drop the

Hatshy [7]

First step.

If we multiply by 3 the first equation and by 2 the second equation we get the first step:

$\begin{gathered} 6x-12y=54 \\ 6x+6y=0 \end{gathered}$

therefore, the answer for the first box is: Multiplication property of equality.

Second step.

If we subtract both equations, we have

$-18y=54$

then, the answer for the second box is: Subtraction property of equality

Third step.

By dividing both sides of our last result by -18, we get

$y=\frac{54}{-18}=-3$

then, the answer for the third step is: Division property of equality.

Fourth step.

Once we have obtained the result for variable y (which is -3), we need to find the result for variable x. So, by substituting our result for y into the first equation, we have

$2x-4(-3)=18$

Therefore, the answer for the fourth box is: Substitution property of equality.

Fifth step.

Then, by simplifying our last result, in which there is a product of -4 and -3, we get

$2x+12=18$

Thefore, the answer for the fifth box is: Simplify.

Sixth step.

Now, by subtracting 12 to both sides, we have

$2x=6$

then, the answer for the sixth box is: Subtraction property of equality.

Seventh step.

Finally, by dividing both sides by 2, we obtain

$x=3$

Then, the answer for the seventh box is: Division property of equality.

The value of x must be greater than <br> .

iogann1982 [59]

we know that

The <u>Triangle Inequality Theorem,</u> states that the sum of the lengths of any two sides of the triangle is greater than the length of the third side

so

$AB+AC > BC\\AB+BC > AC\\AC+BC > AB$

we have

$AB=12\ units\\AC=15\ units\\ BC=x\ units$

substitute the values

$12+15 > x$ -----> $x < 27\ units$

$12+x > 15$ -----> $x > 3\ units$

$15+x > 12$ -----> $x > -3\ units$

$3\ units < x < 27\ units$

therefore

<u>the answer is</u>

The value of x must be greater than $3$

Find the sum and product of zeroes of the quadratic polynomial 3x² + 5x-2.

Alex17521 [72]

Answer:

see first of all it is a quadratic polynomial so it will have 2 zero alpha and beta

now , we will find value of a , b, c

so,

a= 3

b= 5

c= -2

now, sum of the zeros ( alpha + beta) =-b/a

so,-5/3

now product of zeros (alpha *beta) = c/a

so, it will we -2/3

hope you get it !
