Answer:

Because, Angle ABC is incribed in arc AC .

We know that it's 2times than angle ABC.

THEREFORE, 60 × 2 = 120

Answer:

B. 120° degrees

Step-by-step explanation:

Inscribed angle ABC = 60°

Arc AC = 2 * < ABC (Relation between arc and inscribed angle)

Arc AC = 2 * 60°

= 120°

Five less than half the distance from Delaney’s home to the mall is more than 6 miles.

vovikov84 [41]

let x = the distance from Delany's house to the mall

so half the distance would be 1/2x

then it is 5 miles less than that so you would subtract 5 to give you 1/2x-5

and that is more than 6 miles so you get 1/2x-5>6

Use the quadratic formula to solve the equation. -2x^2-x+7=0.

Furkat [3]

<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c

using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))

(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify

(1±√(1+56))/4

1±√(57)/4 is your answer

What’s is the slope of the lin

Lady bird [3.3K]

Answer:

1/3

Step-by-step explanation:

<em>Method 1.</em>

slope = rise/run

Rise is vertical distance.

Run is horizontal distance.

Find two points that are easy to read (on grid intersections):

(2, -1) and (5, 0).

Start at (2, 1). You need to go to (5, 0) by moving only vertically and horizontally. Go up 1 unit. That is a rise of 1. Now go right 3 units. That is a run of 3.

rise = 1

run = 3

slope = rise/run = 1/3

<em>Method 2.</em>

Use the slope formula and two points on the line.

$slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}$
