Learning Task 2 without graphing tell whether the graphs of the system of equations are parallel, perpendicular,intersecting or coinciding
1.y = x + 7 and y = - x + 2
2.Y = 5x and y = 5x - 1
3. 2x + y = 1 and 2y + 4x = 2
4. Y = 2x + 3 and y = -x - 4
Answer:
1.Perpendicular
2. Parallel
3. Parallel
4.
Step-by-step explanation:
If two lines are parallel, slope is equal
If perpendicular, product of slopes is -1
y = mx + c is the general equation of a line form
m represents slope
1. slope is -1 and 1, they are perpendicular
2. Slope is 5 in both cases, they are parallel
3. slope is equal; equation ii is same as i if rewritten
They are parallel
4.

20. Steve has $30 and he earns $5 an hour parking cars. Write an equation to represent how much
money in dollars (m) Steve has after any number of hours parking cars (h). Then use the equation to
determine after how many hours of parking cars willSteve have $105. (Show your work)
Answer:
$30+m($5 x h)
he will be working for 21 h
Step-by-step explanation:
So, Steve has $30, so you want to add that amount to the amount he earn, which is $105.
$5 times 21 is $105
h = 21
but we still need for m but, we already have m
m = $105
john swims 5/12 of a mile in 3/8 of an hour. What distance, in miles, does john swims in an hour?
A.) 1 5/9
B.)15/96
C.)5/20
D.)1 5/12
Answer:
1 1/9 miles
Step-by-step explanation:
If john swims 5/12 of a mile in 3/8 of an hour, then;
5/12 miles = 3/8 hours
TO get the number of miles he swims in an hour, we will say;
x miles = 1 hour
Equating both expressions
5/12 miles = 3/8 hours
x miles = 1 hour
Cross multiply
3/8 x = 5/12
3x/8 = 5/12
3x * 12 = 5 * 8
36x = 40
x = 40/36
x = 10/9
x = 1 1/9
The amount he swims in an hour is 1 1/9 miles

Step-by-step explanation:
a) 94x^2+15x-25
b)34^2+15x-25
c)27x+3
d)34x^2-15x-25
Answer:
d) 34x^2 - 15x -25
( (8x + 5) * (8x - 5) ) - 5x(6x +3 )
= 64x^2 - 25 - 30x^2 - 15x
= 34x^2 - 15x - 25

Jackie won tickets playing the bowling game at the local arcade. The first time, she won 60 tickets. The second time, she won a bonus, which was 4 times the number of tickets of the second prize. Altogether she won 200 tickets. How many tickets was the second prize?
28 is the number of tickets of the second prize
How to calculate how many tickets the second prize is?
A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation
Given that:
The first time wins = 60 tickets
The second time, she won a bonus, which was 4 times the number of tickets of the second prize
Altogether she won 200 tickets
Let N represent the number of tickets of the second prize
This can be written as:
60 + N + (4×N) = 200
60 + N + 4N = 200
60 + 5N = 200
5N = 200 -60
5N = 140
N = 140/5
N = 28
Therefore, the number of tickets of the second prize is 28

Identify the slopes and y-intercepts of the following graphs:
*write the slopes as a fraction or improper fraction using /.
slope =
y - intercept = ( , )
Answer:
-1.5 y 3
Step-by-step explanation:
enjoy enjoy hopefully it's right
Answer:
Slope = -3/2
y-intercept = 3
Step-by-step explanation:
Select any two points.
(x₁ , y₁) = (0, 3) & (x₂ , y₂) = (2 , 0)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\frac{0-3}{2-0}\\\\=\frac{-3}{2}[/tex]
y - y₁ = m(x -x₁)
y - 3 = [tex]\frac{-3}{2}(x - 0)[/tex]
y - 3 = [tex]\frac{-3}{2}x[/tex]
[tex]y = \frac{-3}{2}x + 3[/tex]
Compare with y = mx + c
Slope = -3/2
y-intercept = 3
You start hiking at an elevation that is 80 meters below base camp.
You increase your elevation by 42 meters. What is the new elevation
with respect to base camp?
Answer:
You are now 38 m below base camp.
Step-by-step explanation:
Consider the provided information.
You start hiking at an elevation that is 80 meters below base camp.
Now your initial location is 80 m below base camp, that can be represents as: -80
Now you increase your elevation by 42.
So you go up by 42.
In other words, you get the equation -80+42 = -38.
Since a negative value is below the base camp, this means that you are now 38 m below base camp.
write the following as a fraction in simplest form and as a decimal:
143%
6%
1/2%
1.9%
3/4%
Answer:
1.43
0.06
0.005
0.019
0.0075
Step-by-step explanation:
143% = 143/100 = 1 whole 43/100 = 1.43
6% = 6/100 = 3/50 = 0.06
1/2% = 0.5% = 0.5/100 = 1/200 = 0.005
1.9% = 1.9/100 = 19/1000 = 0.019
3/4% = 0.75/100 = 75/10000 = 3/400 = 0.0075

Q1. Solve the linear equation
a) y - 3 = -5
Greetings.
The answer is y = -2.
Explanation:
The equation is defined to solve for y-term. Our y is currently our subject at this point and needs to be solved.
We move -3 to another side and leave y as the subject of equation. Moving to another side will change the sign/operator to opposite.
Plus ---> Minus
Minus ---> Plus
Multiply ---> Divide

8w-7/4
Step-by-step explanation:
Write the equation of the line that passes through the given points.
(15/8,0) and (17/8,1/2)
The equation of the line is _______.
Answer:
Step-by-step explanation:
Going from (15/8,0) to (17/8,1/2), we see that x (the 'run') increases by 2/8, or 1/4, and that y (the 'rise') increases by 1/2. Thus, the slope of this line through the given points is m = rise / run = (1/2) / (1/4) = 2.
Using the point-slope formula for the equation of a line, we obtain:
y - 0 = 2(x - 15/8), or
y = 2(x - 15/8) (simplest form), or
8y = 2x - 15/4, or
2x - 8y = 15/4, or
8x - 32y = 15
All of these are correct; they are 'equivalent.'
