Answer:
x=-1 and y=4
Step-by-step explanation:
y=-3x+1
2x+5y=18
Put x and y on the same side for 1st equation
3x+y=1
2x+5y=18
Multiply top by -5
-15x-5y=-5
2x+5y=18
Add both equations onto each other
-13x=13
x=-1
Plug x=1 into any equation used
2(-1)+5y=18
-2+5y=18
5y=20
y=4
Answer:
b = $48000, m = $3187.5 / year
Step-by-step explanation:
The equation of a linear function is given as y = mx + b, where m is the rate of change, b is the value of y when x = 0, y = dependent variable and x = dependent variable.
Given that V = mt + b:
b = initial price of the house at 0 years = $48000
V = mt + 48000, At 8 years the house is appraised at $73,500
73500 = 8m + 48000
8m = 73500 - 48000
8m = 25500
m = 3187.5
Answer: Confusing.
If it's f(x) is 2 times 2 minus 8, it's a horizontal line at y-4.
If it's f(x) is 2x 2-8
It's handy to use a graphing calculator.
Step-by-step explanation:
Be sure to clarify what the equation means
Thanks to Desmos for the graphs.
As you can see, the numbers could represent a lot of different things-- especially when 'x' can be a variable -- or confused with the multiplication sign.
Answer:
Angle 2 = 105
Step-by-step explanation:
Since these angles are cut by a transversal the angle from above is congruent to angle #2. You can say the theorem that is used to make these two congruent is the Alternate exterior angles theorem which states this.
Hope this helped!
