What is the measure of ∠XBC?

Angelina_Jolie [31]

Answer:

m∠XBC = 135

Step-by-step explanation:

What is the measure of ∠XBC?

m∠XBC = m∠BAC + m∠BCA

3p – 6 = p + 4 + 84

3p – 6 = p + 88

2p – 6 = 88

2p = 94

From the simplified expression, we need to find the value of p first

From the last line we can see that;

2p =94

Divide both sides by 2:

2p/2 =94/2

p = 47

From the expression, m∠XBC =3p-6

m∠XBC = 3(47)-6

m∠XBC = 141 -6

m∠XBC = 135

Hence the measure of m∠XBC is 135

The graph shows a function. Find the value of b and d.

True [87]

Answer:

The required values are b=-6 and d=4

Step-by-step explanation:

The graph corresponds to the function

$r(x) =x^2+bx^2+8x+d$

We are required to find the values of b and d.

They can be found by using two points that are clearly visible on the graph. For example, the points (0,4) and (2,0) belong to the function. Substituting their values in the function:

$4 =0^2+b*0^2+8*0+d$

Simplifying:

4 = d

d = 4

Now use the point (2,0):

$0 =2^2+b*2^2+8*2+d$

Since d=4, and calculating

$0 =4+4b+16+4$

Simplifying:

$4b = -24$

Dividing by 4:

$b = -24/4 = -6$

$b = -6$

The required values are b=-6 and d=4
