Answer:

fgi = 48

fgh = 24

hgi = 24

Step-by-step explanation:

Bisection divides an angle into two equal angles,

So,

4x - 20 = 3x - 9

4x - 3x = - 9 + 20

x = 11

fgi = 3x - 9 + 4x - 20

= 3x + 4x - 20 - 9

= 7x - 29

= 7 ( 11 ) - 29

= 77 - 29

fgi = 48

fgh = 3x - 9

= 3 ( 11 ) - 9

= 33 - 9

fgh = 24

hgi = 4x - 20

= 4 ( 11 ) - 20

= 44 - 20

hgi = 24

4x+11y=7<br><br>4x+3y=-1<br>what are the steps
andreev551 [17]

Answer:

x = -1, y = 1

Step-by-step explanation:

Given that:

\begin{bmatrix}4x+11y=7\\ 4x+3y=-1\end{bmatrix}

Isolate x for 4x + 11y = 7 which ⇒ x=\frac{7-11y}{4}

Substitute x=\frac{7-11y}{4} into the equation: which is:

\begin{bmatrix}4\cdot \frac{7-11y}{4}+3y=-1\end{bmatrix}

Drop Down to:

\begin{bmatrix}7-8y=-1\end{bmatrix}

Isolate y for 7-8y = -1: y = 1

Thus, x=\frac{7-11y}{4}

Substitute y = 1

Hence,

x=\frac{7-11\cdot \:1}{4}=-1

Solution ⇒ x = -1 and y = 1

What is the explicit rule for the arithmetic sequence shown in the graph?​
Afina-wow [57]

Answer:

Step-by-step explanation:

Looking at the given graph, the slope of the line is expressed as

Slope = (y2 - y1)/(x2 - x1)

y2 = 19.5

y1 = 9.5

x2 = 6

x1 = 1

Slope = (19.5 - 9.5)/(6-1)

Slope = 10/5 = 2

The successive terms is increasing by 2

The formula for the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a is the first term of the sequence

n is the number of terms in the sequence.

d is the common difference.

From the information given,

a = 9.5

Tn = an

d = 2

The explicit rule for the arithmetic sequence will be

an = 9.5 + 2(n-1)
