M<FIB = 90 -  (4x+3)
m<FIB = 87 - 4x

---------------------
m<HFG = 90 - (5x + 4)
m<HFG = 86 - 5x

-------------------------------
<BCF = 180 - (<CBF + <CFB)
<CBF  = 10x + 3
<CFB =90 - <CFD
but <CFD = <HFG = 86 - 5x (vertical angles)

<CFB =90 -(86 - 5x) = 4 + 5x

<BCF = 180 - (10x + 3  + 4 + 5x)
<BCF = 180 - (15x + 7)
<BCF = = 173 - 15x

Use the point-slope form to write an equation of a line through the given points.
Luden [163]

Answer:

y-2=1/3(x+3)

Step-by-step explanation:

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

m=(4-2)/(3-(-3))

m=2/(3+3)

m=2/6

simplify

m=1/3

y-y1=m(x-x1)

y-2=1/3(x-(-3))

y-2=1/3(x+3)

1.23÷10 = 0.123 is a true statement

Given the expression 1.23÷10, we need to<u> check if the expression is equal to 0.123</u>

<h3>Fractions</h3>

Fractions is a ratio of two integers a/b

Given

  • 1.23÷10

Convert the decimal to a fraction as shown:

  • 1.23 = 123/100

The expression becomes:

  • 123/100 ÷10

= 123/100 * 1/10

=  123/1000

Convert back to decimal

1.23÷10 = 0.123

This shows that 1.23÷10 = 0.123 is a true statement

Figure LMNO maps to L’M’N’O’ by a 125° rotation about point T Which congruency statement is correct?
devlian [24]

We have been given that Figure LMNO maps to L’M’N’O’ by a 125° rotation about point T. We are asked to choose correct congruency statement about our figures.

Since we know that rotations are isometric and they preserve angle measures.

We can see that after rotating figure LMNO about point T, angle L will correspond to angle L' and angle M, N and O will correspond to angles M', N' and O' respectively.

Therefore, figure LMNO will be congruent to L'M'N'O' and first option is the correct choice.

Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS,and 25 cents per off-peak time SMS.
algol [13]

Answer:

Anita's monthly bill will be $164.25.

Step-by-step explanation:

Since Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS, and 25 cents per off-peak time SMS, if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month To determine what will her monthly bill come to, the following calculation must be performed:

100 + (0.85 x 45) + (0.25 x 105) = X

100 + 38.25 + 26.25 = X

138.25 + 26.25 = X

164.25 = X

Therefore, her monthly bill will be $ 164.25.
