Answer:

Step-by-step explanation:

As you can see from the image attached below, the equation that is being graphed is

F(x) = $\frac{x}{(x+4)(x-1)}$

This equation splits off into various directions because the denominator is turns into a quadratic equation. Once solved it provides two values for which the quadratic equation would equal zero. Since this equation is the denominator 0 would give a null value and is why on the graph there is no y value for 1 or -4. Yet all other values are valid and have an different y output.

Answer:

x = -5 y = -9

Step-by-step explanation:

y = x -4

5x + y = - 34

substitute x-4 in for y to solve for x

5x + x - 4 = 34

solve for x . . . add 5x + x = 6x

so you now have 6x-4 = -34

add 4 to both sides of the equation

6x-4 + 4 = -34+ 4

6x = -30

divide both sides by 6

6x/6 = -30/6

x= -5

then you plug -5 for x in the first equation

y = x - 4

y= -5 -4

y =-9

x= -5 y= -9

Answer: OPTION C.

Step-by-step explanation:

The area of a triangle can be calculated with the following formula:

$A=\frac{bh}{2}$

Where "b" is the base of the triangle and "h" is the height of the triangle.

You know that all the triangles that compose the large triangle are equal.

According to the information given in the exercise, the base and the height of any small triangle are:

$b=6\ in\\h=7\ in$

Therefore, the area of any of them is:

$A=\frac{(6\ in)(7\ in)}{2}\\\\A=21\ in^2$

Since there are 4 equal triangles, you need to multiply the area obtained by 4 in order to find the area of the large triangle. This is:

$A_{large}=4(21\ in^2)\\\\A_{large}=84\ in^2$

Sam and Annika ride their bikes to school. Sam rides his bike (K )kilometers. Annika rides her bike two less than four times as

Gekata [30.6K]

S=k, a=4k-2

Annika rides her bike so she must travel some positive distance, ie a>0 so:

4k-2>0

4k>2

k>1/2 and that k is how far Sam rode, so Sam must ride his bike more than 1/2 kilometer.
