-15 i think if not u just got to use the quadratic formula.

I don't exactly know what you're trying to solve but x=6

Question 5 of 5 Triangle ABC is an equilateral triangle. How many lines of symmetry does triangle ABC have?

lutik1710 [3]

I believe just 1 because an equilateral triangle can only be reflected on one line for the halves to be the same

Find the y-intercept of the line who's equation is Y = 3.5 x- 0.4.

agasfer [191]

$\sf y=mx+b$

m is the slope
b is the y-intercept

so that means that the y-intercept of

$\sf y=3.5x + .4$

is $\sf .4$

$\bf{\huge{\boxed{y-intercept = .4}}}$

I don’t understand at all

Savatey [412]

Answer and Step-by-step explanation:

The parent function, f(x) = |x|, has no transformations applied to it.

When the number is with the x, it translates the graph horizontally. <->

When the number is outside of the absolute box, it translates the graph vertically. ^ V

When the number is multiply the absolute box on the outside with the x inside, it scales the graph.

So, first lets apply the translations of horizontal and vertical shift.

The graph translated 1 units downwards.

The graph translates 2 units to the right.

g(x) = |x - 2| - 1

We subtract the 2 because that makes it go right, while if we added it would go left.

Now for the scale.

The lines have a slope of $\frac{1}{4}$ , so that is what we are multiplying.

g(x) = $\frac{1}{4}$ |x - 2| - 1

^That is your transformed function.

1) Has zeros at -2 and 4, both being double roots 2) As x→∞, y→−∞

irina1246 [14]

-(x+2)^2(x-4)^2

Not that if x= -2 and x=4 they will look like this in an equation: (x+2) and (x-4)
When (x+2) and (x-4) are set equal to zero and you solve for x, x will equal x= -2 and x=4

If they have double roots, they have a multiplicity of 2 (per root) meaning they will bounce off of the x-axis. Multiplicity can be found by using exponents.

The negative in front flips the function over the x-axis and holds true to the given limit.
