<span>y=4x−1;y=2x−5
Step: Solve y=4x−1 for y:
Step: Substitute 4x−1 for y in y=2x−5:
y=2x−5
4x−1=2x−5
4x−1+−2x=2x−5+−2x(Add -2x to both sides)
2x−1=−5
2x−1+1=−5+1(Add 1 to both sides)
2x=−4
2x/2=−4/2(Divide both sides by 2)
x=−2
Step: Substitute−2 for x in y=4x−1:
y=4x−1
y=(4)(−2)−1
y=−9(Simplify both sides of the equation)
<u>Answer:</u>y=−9 and x=−2</span>
Answer:
10⁴ is 10,000 written as a power with a base of 10
1. 64y^9
2.256u^12v^4
3.8a^3b^4 * b^4
4. vu^4 * 8vu^6
Circumference of the circle = pi * diameter = 3.14 * 13 = 40.82
Length of EG = 40.82 * 280 / 360 = 31.7 cm.
