Consider the following pair of equations:
y = −2x + 8
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(3,2)
Step-by-step explanation:
y = -2x + 8
y = x-1
Substitute x-1 for y in the equation y = -2x + 8. x-1 = -2x + 8
Use the Additive Property to move the
constant terms to one side of the equation. x-1 = -2x + 8
+1 +1
x = -2x + 9
Now do the same to the variable terms. +2x +2x
3x = 9
Divide both sides of the equation by the
constant in the variable term. ÷3 = ÷3
x = 3
To find y, simply substitute the value of x into
one of the original equations. y = x-1
y = 3-1
Solve: y = 2
The solution is (3, 2).

A factory produces 80,000 candies each day.They produce equal quantity of four flavors:cherry,lemon,orange and strawberry. The candies are mix together during packaging. What is the probability of selecting orange.
Answer:
1 /4
Step-by-step explanation:
Total number of candies produced per day = 80,000
Number of flavors made = 4
Since the number of each flavor produced are equal ;
Number of each flavor produced :
80000 /4 = 20000
Probability of selecting orange flavor :
Number of orange flavor / total candies produced
= 20000 / 80000
= 1/4

A superhero and his sidekick simultaneously leave the city and fly toward a secret hideout that is 1800 km away. The superhero's speed is 100 km/h slower than the sidekick's speed, and so he arrives at the hideout 36 minutes after his sidekick. Find the speed of each
Answer:
Speed of sidekick : 600
Speed of superhero : 500
Step-by-step explanation:
x = sidekick speed
speed of hero = x-100
Time of hero = -36
1800/(x-100) = (1800/x) + 0.6
That equations solves to x = 600 and x = 500 or -500
The given difference in speed and the arrival time, as well as the
distance traveled, gives the speeds as 500 and 600 km/hr.
Response:
The speed of the superhero is 500 km/hr.The speed of the sidekick is 600 km/hr.Which method is used to calculate the speed of the superhero, and the sidekick?The given parameters are;
Superhero's speed = 1800 km
Speed of the superhero = Speed of the sidekick - 100 km/h
The time the superhero arrives at the hideout = 36 minutes after the sidekick = 0.6 hours
Required:
The speed of the superhero and the sidekick
Solution:
Let v represent the speed of the superhero, we have;
v × (t + 0.6) = (v + 100) × t
v·t + 0.6·v = v·t + 100·t = 1800
0.6·v = 100·t
[tex]t = \dfrac{0.6}{100} \cdot v[/tex]
Therefore;
0.006·v² + 0.6·v - 1800 = 0
Which gives;
v² + 100·v - 300,000 = 0
(v - 500)·(v + 600) = 0
v = 500, or v = -600
The speed of the superhero is 500 km/hThe speed of the sidekick is 500 km/h + 100 km/h = 600 km/hLearn more about speed and velocity here:

A 13.5-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the fire truck) if the ladder makes an angle of 59 22' with the horizontal.
Answer:
11.6m
Step-by-step explanation:
A 13.5-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the fire truck) if the ladder makes an angle of 59 22' with the horizontal.
We solve the above question using the Trigonometric function of Sine.
sin θ = Opposite/ Hypotenuse
Hypotenuse = Length of the ladder = 13.5m
Opposite = d
θ = 59° 22'
= 59° + 22/60
= 59° + 0.367
= 59.367°
Hence,
sin 59.367 = d/13.5m
d = sin 59.367 × 13.5m
d = 11.616057416m
Approximately = 11.6m
Therefore, the distance d the ladder goes up the wall is 11.6m

The external angle of a triangle:An external angle of a triangle is an angle formed by extending one side of the triangle and intersecting with the extension of another side.
In a triangle, the measure of an external angle is equal to the sum of the measures of the two opposite interior angles.
Here we have a triangle
Let the ABC be the triangle as given in the picture
=> ∠A = 38°
From the baseline BC
=> Measure of B = 180° - 101° = 79°
As we know
In a triangle, the measure of an external angle is equal to the sum of the two opposite interior angles
=> x = ∠A + ∠C
=> x = 38° + 79°
=> x = 117°
Therefore,
The size of the angle 'x' is 117°
