What is an equation of the line that passes through the points (-4, -1)(−4,−1) and (6, -1)(6,−1)?

Vlada [557]

$\boxed{y=-1}$

<h2>Explanation:</h2>

In order to solve this problem, let's remember the point-slope form of the equation of a line:

$y-y_{1}=m(x-x_{1}) \\ \\ m:slope \\ \\ (x_{1},y_{1}):A \ point \ on \ the \ line$

We know two points:

$(x_{1},y_{1})=(-4, -1) \\ \\ (x_{2},y_{2})=(6, -1)$

So:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{-1-(-1)}{6-(-4)} \\ \\ m=0$

So this is a constant line (slope equals zero). Therefore, every point has a y-coordinate $y=-1$ . In other words, the equation is:

$\boxed{y=-1}$

Solve the system of equations

Blababa [14]

Answer:

x = 3

y = 1

Step-by-step explanation:

(2x + 4y = 10) * 2 = (4x + 8y =20)

4x = 20 - 8y

Plug that into the other equation

(20 - 8y) - y = 11

-9y = -9

y = 1

Plug this value into one of the original equations

2x + 4(1) = 10

2x = 6

x = 3

Find (fºg)(1)<br> f(x) = x² - 1<br> g(x) = √x <br> A.0<br> B.1<br> C.4 √2<br> D. √8

Savatey [412]

Given:

The function are

$f(x)=x^2-1$

$g(x)=\sqrt{x}$

To find:

The value of $(f\circ g)(1)$ .

Solution:

We have,

$f(x)=x^2-1$

$g(x)=\sqrt{x}$

We need to find the value of $(f\circ g)(1)$ .

$(f\circ g)(1)=f(g(1))$ $[\because (f\circ g)(x)=f(g(x))]$

$(f\circ g)(1)=f(\sqrt{1})$ $[\because g(x)=\sqrt{x}]$

$(f\circ g)(1)=f(1)$

$(f\circ g)(1)=(1)^2-1$ $[\because f(x)=x^2-1]$

$(f\circ g)(1)=1-1$

$(f\circ g)(1)=0$

The value of $(f\circ g)(1)$ is 0.

Therefore, the correct option is A.

Which are sums of perfect cubes? Check all that apply.

vichka [17]

I think these are the sums of perfect cubes.

A = (2x²)³ + (3)³
B = (x³)³ + (1)³
D = (x²)³ + (x)³
E = (3x³)³ + (x^4)³
