Answer:
Step-by-step explanation:
3x - 4y = -11
x - 2y = -5
Compare the coefficients of the variables.
The coefficients of the x terms, 3 and 1, are multiples of each other.
The coefficients of the y terms, -4 and -2, are also multiples of each other.
That makes it easy to eliminate either variable.
I'll eliminate the y variables. Multiply the second equation by -2, then add it to the first equation:
₋-2x + 4y = 10
3x - 4y = -11
--------------------
x + 0y = -1 , so x = -1.
Substitute -1 for x in either equation and solve for y:
3(-1) - 4y = -11
y = 2
(x,y) = (-1, 2)
Answer:
x=150°
Step-by-step explanation:
angle FEB is the same with angle AEG
Answer:
The inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.
Step-by-step explanation:
From the information provided, you can write an inequality where total cost for people attending at the party should be less than or equal to $300:
3.50p+5.00p≤300
8.50p≤300
Now, you can solve for p:
p≤300/8.50
p≤35
According to this, the answer is that the inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.
Answer:
0
Step-by-step explanation:
Separate into two parts

Simplify:
This is for the first fraction



Now for the second fraction:



Add both parts together

To turn this into the said formula, that would become:

Where:
a=0
b=1
c=1
d=3
Any value with an exponent 0 except zero will be equal to 1
Given,
y = -3x+1 (EQ1)
y = 2x-4 (EQ2)
Equate EQ1 and EQ2
EQ1 = EQ2
-3x+1 = 2x-4
-3x-2x = -4-1
x = 1
y = -3x+1
y = -3(1)+1
y = -3+1
y = -2
(1, -2)
