From what you are describing you should just simply plug in the x and y coordinates.

-2(-2)+4(1)=8

-2(0)+4(2)=8

How do you solve 0.75(8+e)=2−1.25e ?
mash [69]
Distribute first.
.75 times 8 + .75 times e, which is 6+.75e = 2-1.25e
Then subtract 2 from both sides,
4+.75n=-1.25e
Next subtract .75 from both sides,
4=-2e
Divide both sides by -2, and you will get e= -2. Hope this helps!

The graph of the function f(x) = –(x + 6)(x + 2) is shown below.Which statement about the function is true?
LekaFEV [45]

Answer:

The first statement is true.

Step-by-step explanation:

The function is f(x) = - (x + 6)(x + 2)  

⇒ f(x) = - x² - 8x - 12

Now, condition for a function f(x) to be increasing at x = a is f'(a) > 0.

Now, f(x) = - x² - 8x - 12

⇒ f'(x) = -2x - 8 {Differentiating with respect to x}

Now, f'(a) = -2a - 8 {Here a can be any real value}

And, the condition for increasing function at x = a is  

- 2a - 8 > 0

⇒ - 2a > 8

⇒ a < - 4

Therefore, the first statement is true i.e. the function is increasing for all real values of x where  x < – 4. (Answer)

the base of a triangle is 11ft more than the height. if the area is 51ft^2 find the base and the height
nekit [7.7K]
So.. notice the picture below

and thus, we also know, that A = 51, thus

\bf A=\cfrac{1}{2}bh\implies A=\cfrac{(h+11)h}{2}\implies A=\cfrac{h^2+11h}{2}\qquad A=51&#10;\\\\\\&#10;51=\cfrac{h^2+11h}{2}\implies 102=h^2+11h\implies 0=h^2+11h-102&#10;\\\\\\&#10;0=(h+17)(h-6)\implies &#10;\begin{cases}&#10;0=h+17\implies &-17=h\\&#10;0=h-6\implies &6=h&#10;\end{cases}

now, the height is just a value, it can't be negative, thus  we can rule out -17, thus h = 6

and surely you'd know what the base is
