As the school’s sign language interpreter, Kiran gets paid $34 for every parent-teacher conference that he attends. He also gets paid $22 per school-related assembly that he attends as an interpreter. If Kiran earns $1008 for 36 paid events, how many parent-teacher conferences and how many school-related assemblies did he attend ?
Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.
Let x represent the number of parent-teacher conference and y represent the school-related assembly.
Since Kiran earns $1008 for 36 paid events, hence:
x + y = 36 (1)
34x + 22y = 1008 (2)
Solving equations 1 and 2 simultaneously gives:
x = 18, y = 18
Therefore Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.

The number of women elected to the us house of representatives has increased nearly every congress since 1985 in ths 99th Congress to beginning in 1985 there were 22 female representatives in the 109th Congress beginning in 2005 there were 68 female representatives write a linear eauation that models the number of female members lf the house of representatives x years after 1985
Answer:
y = 2 · 3 x + 22
Step-by-step explanation:
Analysis: Number of female representatives in 1985 = 22
This can be represented by the point (0,22).
Number of representatives in 2005 = 68.
This can be represented by the point (2205-1985,68)
= (20,68)
Slope of the line : [tex]\frac{68-22}{20-0} =\frac{46}{20} =\frac{23}{10} =[/tex] 2 · 3
∴ Equation of the line : y = mx + c
⇒ 22 = 2 · 3 (0) + c
⇒ C = 22
∴ y = 2 · 3 x + 22
A few weeks ago, Tori bought 4 apples from her local farmers' market. Today, she bought 3 apples. What is the percent of decrease in the number of apples bought?
Answer:
25%
Step-by-step explanation:
(original value - new value / original value) x 100
So
4 - 3 = 1
1/4 = 0.25
0.25 x 100 = 25
So there was a 25% decrease in the number of apples bought.
Hope it helps :)
List the first 4 terms of the sequence 3n² + 1
Answer:
4, 13, 28, 49
Step-by-step explanation:
1st term = 3 × (1)² + 1 = 4
2nd term = 3 × (2)² + 1 = 13
3rd term = 3 × (3)² + 1 = 28
4th term = 3 × (4)² + 1 = 49
The first for terms of the series can be found by substituting the n for the term it is:
= 3(1)² + 1 , 3(2)² + 1 , 3(3)² + 1 ,3(4)² + 1
= 4, 13, 28, 49

3x + 2 = 26
Answer:
x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
Undo what is done to x. We see that x is multiplied by 3 and then 2 added. We undo these steps in reverse order.
3x +2 = 26 . . . . . . given
3x = 24 . . . . . . . . . subtract 2 from both sides of the equation
x = 8 . . . . . . . . . . . divide both sides of the equation by 3

Geometry
Answer:
m∠6 = 54°
Hope this helps!
Step-by-step explanation:
( 13x+9 ) and angle 4 are congruent meaning the same. That means angles 5 and 8 are also congruent to ( 13x + 9 ).
Angle 5 or angle 8 are Supplementary to angle ( 5x + 9 ) so a Supplementary angle is 180° and we need to find out x. ( 13x + 9 ) + ( 5x + 9 ) = 18x + 18.
Because Supplementary angles equal 180°, 18x + 18 = 180
18x = 162 x = 162/18 x = 9
Because ∠6 is congruent to angle ( 5x + 9 ), ∠6 = ( 5(9) + 9 )
∠6 = 45 + 9 ∠6 = 54
Find the missing angle measures. Be sure to show your work in arriving at your answers.

Answer:
k=50º
m=90º
Step-by-step explanation:
a line is 180º total
so 130+k=180
k=50
a triangle also is 180º total
so 180-40-k=m
180-40-50=m
90=m

Answer:
- 7x^2 + 3xy - 9y
Step-by-step explanation:
(2xy- 4x^2) - (9y + 3x^2 - xy)
Add the second polynomial:
Change all the signs in the second polynomial because it has a negative sign before the parentheses.
= 2xy - 4x^2 - 9y - 3x^2 + xy
Combine like terms:
(-4x^2 - 3x^2) + (2xy + xy) - 9y
= -7x^2 + 3xy - 9y
John makes $8.25 per hour after he got a 50 cent raise. Write the equation

8.25+50
Step-by-step explanation:
Determine
f(a + h) - f(a)
for f(x) = 1 - x2 and simplify.
Answer:
h^2+2ah
Step-by-step explanation:
When f(x) = 1-x^2
f(a) = 1 - a^2
f(a+h) = 1 - (a+h)^2
= 1 - a^2 + 2ah + h^2
Subtracting the two:
f(a+h) - f(a)
= (1 - a^2 + 2ah + h^2) - (1-a^2)
= 1 - 1 - a^2 + a^2 + 2ah + h^2
= 2ah + h^2
= h^2 + 2ah

Answer:
a) 5/4
b) y = 5/4x + 27
Step-by-step explanation:
To find the gradient of a line, simply change the equation into slope intercept form (y = mx + b), where b is the y-intercept and m is the slope.
4y - 5x = 2
4y = 5x + 2
y = 5/4x + 1/2
m(gradient) = 5/4
For lines to be parallel, simply keep the gradient the same. Any line with a gradient, or slope, of 5/4 will be parallel. As such, simply keep the first two terms identical, and change the y-intercept into any number.
Hope it helps :)
Graph the following features:
Y-intercept = -2
Slope = 1
Answer:
Follow the steps below!
Step-by-step explanation:
If you're provided with a graph then use that, but if not, draw it with a scale of 1 unit per 1 tick and all four quadrants.
Start at -2 on your y-axis (two ticks down from the origin the vertical line) and draw a dot or cross. Then, go to the right one tick and up one tick and draw another dot or cross. If you do this again, you should have made a mark on the x-axis (horizontal line). All you need to do is draw a straight line connecting the points you plotted with arrows on the end. You can use a ruler or other straight edge if straight lines are a challenge to draw.

please help I dont understand
Answer:
3rd option
Step-by-step explanation:
A direct variation is expressed in this form:
y = kx
1. y - 4x = 8
y = 4x + 8 is not a direct variation
2. y + 2 = 7x
y = 7x - 2 is not a direct variation
3. y - 3x = 0
y = 3x is a direct variation
4. y = 5x - 2
y = 5x - 2 is not direct variation
What is the change from 3 to -2
what is the value of Y
Answer:
y = 150º
Step-by-step explanation:
The sum of internal angles of a triangle must be 180º and the sum of y + (x-20) forms a straight line which is also 180º, so:
2x + x + (x - 20) = 180
4x - 20 = 180
4x = 200
x = 50
x - 20 = 50 - 20
x - 20 = 30
y = 180 - 30
y = 150º
