1) By the inscribed angle theorem, $m\angle B=\frac{1}[2}(60^\circ})=\boxed{30^{\circ}}$

2) By the inscribed angle theorem, arc RT measures twice 63 degrees, or 126 degrees.

6 yr 7 months+ 2 yr 11 months = ?
6 yr + 2 yr = 8 yr

7 months + 11 months = 18 months = 1 yr 6 months

8 yr + 1 yr 6 months = 9 yr 6 months

answer is C. 9 yr 6 months

Which Graph correctly solves the equation below? -1/2x^2 +2 = 2x^2 -8

lubasha [3.4K]

Answer:

see attachment

Step-by-step explanation:

The given equation is

$- \frac{1}{2} {x}^{2} + 2 = 2 {x}^{2} - 8$

The graph of the left hand side of this equation is

$y = - \frac{1}{2}{x}^{2} + 2$

This quadratic graph has its vertex at (0,2) and turns upside down.

The right hand side of the equation is

$y = 2 {x}^{2} - 8$

This quadratic graph opens upwards and has its vertex at (0,-8).

The two graphs intersects at two points , which are (-2,0) and (2,0).

7th grade math help me pleaseeee

Eduardwww [97]

Answer:

4x + 5y = 20

Step-by-step explanation:

4x + 5y = 20

5y = -4x + 20 (Subtract 4x to isolate 5y. Put the 4x in front of the 20)

y = $-\frac{4}{5}x$ + 4 (Divide all by 5 to isolate y)

And then it's done and in slope-intercept form

$-1< -\frac{4}{5} < 0$ or $-\frac{4}{5}$ is greater than -1 but less than 0

I hope this helped :)
