Angel 2 equals 78 also because they are the exact same size as each other. Also they are vertical angles which makes them the same angel measure.

GIven the equation LaTeX: y=\frac{2}{3}x-1y = 2 3 x − 1, determine the slope of the line.

horrorfan [7]

The general equation for a linear equation is $y=mx+c$

y is the y-coordinate
x is the x-coordinate
m is the gradient of the slope
c is where is passes through the y axis

So if you breakdown this equation ( $y=\frac{2}{3} x-1$ ) you are able to see that 2/3 is in the same spot as 'm' which is the gradient or slope of the line.

Also if there was a negative infront of 'm' then the gradient would slope down '\' instead of up '/'

which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 – 10x 2? righ

irina1246 [14]

Answer:

$5$ units to the right and $23$ units down

Step-by-step explanation:

we have

$f(x)=x^{2}$

This is a vertical parabola open upward with vertex at point $(0,0)$

$g(x)=x^{2} -10x+2$

Step 1

Convert the function g(x) into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$g(x)-2=x^{2} -10x$

Complete the square. Remember to balance the equation by adding the same constants to each side

$g(x)-2+25=x^{2} -10x+25$

$g(x)+23=x^{2} -10x+25$

Rewrite as perfect squares

$g(x)+23=(x-5)^{2}$

$g(x)=(x-5)^{2}-23$

The function g(x) is a vertical parabola with the vertex at point $(5,-23)$

Step 2

Find the rule of the translation

$(0,0)-------> (5,-23)$

$(x,y)-------> (x+5,y-23)$

That means

The translation is $5$ units to the right and $23$ units down
