Answer:
a is a linear equation
Step-by-step explanation:
Time = 2hour +12 mins per lightswitch
She charges her customers a call out fee of £35, plus £30 per hour.
How much should a customer be charged for wiring a house with 10 lightswitch?
Answer:
£395
Step-by-step explanation:
call out fee = 35
30 per hour = 2 hour to be = 60
but, 12 minutes in hour = 12/60 = 0.2
0.2 = 0.2*30 = 6
2 hours and 12 minutes would be charges as
30 + 6 = 36
36*10 = 360
call out fee + per hour = 35 + 360 = 395

Answer:
144
Step-by-step explanation:
Since the triangle is equilateral all the sides are equivalent, meaning you can make any 2 sides equal to eachother
4x + 32 = 12x
32 = 8x
x=4
Replace the x of one of the sides
12(4) = 48
and since we are finding the perimeter multiply 48 by 3 since there are 3 sides
48(3)

9x10^7 is how many times as large as 3x10^-2
Answer:
3000000000 or 3x10^9 times bigger
Step-by-step explanation:
Power in mathematics is defined as the number you get when you get when you raise a number to an exponent
[tex]9 * 10^{7}[/tex] is 3000000000 or [tex]3 * 10^{9}[/tex] times as large as [tex]3 * 10^{-2}[/tex]
To calculate how many times [tex]9 * 10^{7}[/tex] is larger than [tex]3 * 10^{-2}[/tex] we would be dividing [tex]9 * 10^{7}[/tex] by [tex]3 * 10^{-2}[/tex] .This is expressed mathematically as:
[tex]\frac{9*10^{7} }{3*10^{-2}}[/tex]
= 3,000,000,000
or we express it as a power : [tex]3 * 10^{9}[/tex]
Therefore, is 3000000000 or times as large as

write an equation of the line that passes through the given point and is perpendicular to the given line.
Answer:
1. line a and c and parallel. line b is perpendicular with line a and c. 2. line b and c and parallel. line a is perpendicular to lines b and c. 3. y= -3x + 3 4. y=(5/3)x - 9

To find parallel and perpendicular, make the slope opposite and find b by plugging in the points. Parallel is the same slope.
the following chart shows the number of rows in an auditorium and the total number number of seats. what equation defines the number of seats with respect to the number of rows?
a. s=20r+100
b. s=40r+120
c. s=20r+60
d. s=20r
Answer:
The answer is c because 20(20) + 60 = 460 and if you plug in the number of rows for x and add the 60 you would always get the number of seats value.
The correct equation for the number of seats with respect to the number of rows will be;
s = 20r + 60
Where, s is number of seats and r is number of rows.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the power one.
Given that;
The chart shows the number of rows in an auditorium and the total number of seats.
Since, The equation is satisfy the given numbers in chart.
So, Let an equation for chart;
s = 20r + 60
Where, s is number of seats and r is number of rows.
Now, Substitute the value of r = 20 for the number of first rows in above equation we get;
s = 20 × 20 + 60
s = 400 + 60
s = 460
And, For second row, r = 45
s = 20 × 45 + 60
s = 900 + 60
s = 960
Thus, The correct equation for the number of seats with respect to the number of rows will be;
s = 20r + 60
Where, s is number of seats and r is number of rows.

Answer:
y = - [tex]\frac{9}{5}[/tex] x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{9}{5}[/tex] and c = - 4 , thus
y = - [tex]\frac{9}{5}[/tex] x - 4 ← equation of line

Answer:
<1 =100 (check explanation for why)
<2 = 80 (check explanation for why)
<3 = 100 (check explanation for why)
Step-by-step explanation:
You can get <1 from the given angle being a linear pair to <1, so:
180= 80+ <1
100= <1
You can get <2 from being a linear pair to <1, so:
180 = 100 + <2
80 = <2
You can get <3 from being a linear pair to <2
180 = 80 + <3
100= <3
Answer:
m<1= corresponding
m<2=vertical angle
m<3=consecutive interior angle

Ben and his three friends were ordering pizza. They could spend at most $26. If a large
cheese pizza costs $22 and toppings are $0.65 each, how many toppings could they
get?
Answer:
6 toppings
Step-by-step explanation:
The t in this equation represents the amount of toppings.
22 + 0.65t = 26
-22 -22
0.65t = 4
0.65t/0.65 = 4/0.65
t = 6
They could get 6 toppings and the total would be $25.90.

10. x² + 169 = 0
Algebra 2
Answer:
13i, -13i
Step-by-step explanation:
x^2=-169
169=(13)^2
x^2=-(13)^2
the square root of -1 is i ( imaginary number )
(-13)^2=(13)^2 so x is 13i and -13i
Answer:
13i
Step-by-step explanation:
So I would solve for x
This is zero term factoring
This is a square root factor and 169's square root is 13.
However we need to factor -169
This is where imaginary numbers come in. i= Square root of -1
13i would be the answer
