Answer:

Step-by-step explanation:

Basically -1/2 is the slope meaning you go down 1 and go to the right by 2 and then the -2 is the y-intercept meaning when x=0 y=-2

What is the value of x?<br> 12 units<br> 15 units<br> 20 units<br> 25 units

Firlakuza [10]

Answer:

The answer is 12 units.

Step-by-step explanation:

Looking at the figure we see that

$(1).9^2+x^2=SR^2$

$(2).16^2+x^2=RQ^2$ and

$(3).SR^2+RQ^2=(9+16)^2$

Now from equations (1) and (2) we have values for $SR^2$ and $RQ^2,$ so we put those into the equation (3) and get:

$9^2+x^2+16^2+x^2=(9+16)^2$

$\rightarrow 337+2x^2=625$

$\boxed{\therefore x= 12.}$

Therefore the answer is 12 units.

What is y=x by a vertcal stretch of 5

kakasveta [241]

Answer: The vertical stretch of 5 in the equation y = x is defined by $y=5x$ .

Explanation:

The given equation is,

$y=x$

It can be written as,

$f(x)=x$

The function is defined as $S\cdot f(x)$ .

If $S\geq 1$ , then the function has a vertical stretch by a factor of S units.

If $0$ , then the function has a vertical shrink by a factor of S units.

Since we have to find the vertical stretch of 5 in the equation y = x.

$y=5f(x)$

$y=5x$

The below figure shows the graph of y = x and $y=5x$ .

State the value of the discriminant for the equation,<br> 3x^2 + 7x + 3 = 0

Irina-Kira [14]

Answer: 13

Step-by-step explanation:

If you remember the quadratic equation formula;

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

You can easily extract what is under the root to find the discriminant.

$b^2-4ac=?\\$

a = 3

b = 7

c = 3

$(7)^2-4(3)(3)\\49-36=13$
