When solving a system by graphing you need to see where the lines intersect.

Below is a picture of these lines graphed. The green line is y = x +4 and the blue line is y = 4x - 1

The red dot represents the intersection is about (1, 5)

The original point is: (1.667, 5.667)

Hope this helped!

What is x squared equals one twenty one

Iteru [2.4K]

Answer:

x = 11

Step-by-step explanation:

x² = 121

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Root both sides:

√(x²) = √(121)

x = √121 = √(11 * 11)

x = 11

x = 11 is your answer.

Tyree is determining the distance of a segment whose endpoints are A(–4, –2) and B(–7, –7).

PilotLPTM [1.2K]

Answer:

Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.

Step-by-step explanation:

to find the distance between two point A(-4, -2) and B(-7, -7) we use the following distance formula

$d=\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1} )^2 \\\\$

x1=-4, x2=-7

y1=-2, y2=-7

so,

$d=\sqrt{(-7-(-4))^2+(-7-(-2) )^2\\}\\\\d=\sqrt{(-7+4)^2+(-7+2)^2 }\\\\d=\sqrt{(-3)^2+(-5)^2 }\\\\\\\\d=\sqrt{9+25}\\ \\d=\sqrt{34}$
