Answer:

The equation of the perpendicular line is;

y = -4x + 15

Step-by-step explanation:

Firstly, we get the slope of the former line

we do this by comparing its equation with;

y = mx + b

This is the standard form with m representing the slope

Thus;

for y = x/4 -2

y = x(1/4) -2

slope = 1/4

Since the other equation is perpendicular to this line, the product of theirs slopes will give -1

Mathematically;

m2 * 1/4 = -1

m2 = -4

So we want to write the equation of the line with slope -4 and passing the point (4,-1)

we have;

y-y1 = m(x-x1)

y + 1 = -4(x-4)

y = -4x + 16-1

y = -4x + 15

Factor using the trinomial<br> 10.<br> X2 + 13x + 12

Rudik [331]

Answer:

Factoring the trinomial: $x^2+13x+12$ we get the factors $\mathbf{(x+1)(x+12)}$

Step-by-step explanation:

We need to factor the trinomial: $x^2+13x+12$

We can factor the trinomial by breaking the middle term i.e 13x

Such that adding or subtracting gets the both terms we get 13x and multiplying both terms we get 12x^2

We can break 13x as: 12x and x

Adding them we get 13x and multiplying them we get 12x^2

So,

$x^2+13x+12\\=x^2+12x+x+12\\=x(x+12)+1(x+12)\\=(x+1)(x+12)$

So, Factoring the trinomial: $x^2+13x+12$ we get the factors $\mathbf{(x+1)(x+12)}$

What is an equation that is a parabola with a vertex at(-1,-1)

aleksandrvk [35]

The equation for a parabola is y = ((x - a)^2) + b. There is a shift one to the left (we’ll call that a) and one shift down (we’ll call that b) for the point (-1,-1). Shifts to the left and right are replaced with a and shifts up and down are replaced with b. y = ( x - (-1))^2 - 1. Simplify: y = (( x + 1)^2) - 1
