<h3>Answer: C) increase from 45 degrees to 50 degrees</h3>

===============================================

Explanation:

Let's calculate the angle B based off the arcs CDF and GHJ

B = (far arc - near arc)/2

B = (arc CDF - arc GHJ)/2

B = (130 - 40)/2

B = 90/2

B = 45

----------

Now let's change GHJ to 30 degrees, while keeping the other arc the same.

B = (far arc - near arc)/2

B = (arc CDF - arc GHJ)/2

B = (130 - 30)/2

B = 100/2

B = 50

Angle B has increased from 45 degrees to 50 degrees.

Write an equation in point-slope form of the line that passes through the point (4,7) and has a slope of -1.
creativ13 [48]

Answer:

y - 7 = - 1(x - 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 1 and (a, b) = (4, 7) , thus

y - 7 = - (x - 4)

Can someone help me
nexus9112 [7]

Answer:

(2/3)y - (8/3) = x For the first one maybe?


Step-by-step explanation:

1. y = (3/2) x + 4

y - 4 = (3/2) x

(2/3)y - (8/3) = x


2. If output is 2, f(x) = 2.

So, 2 = (3/2) x + 4

-2 = (3/2) x

-4 = 3x

x = -3/4

5x -4(x - 3) - 8 = Ax + B
Brrunno [24]

Answer:

12= ax - x + b

Step-by-step explanation:

5x -4(x - 3) - 8 = ax + b

5x -4x + 12 - 8 = ax + b

x + 12 = ax + b

12= ax - x + b
