Answer: 2, 1.5 , -0.75
(b)
Step-by-step explanation:
Given
line is
Converting it into intercept form
So, the x-intercept is and y-intercept is
The slope is given by
(b) the line perpendicular to the above line and passing through
The slope of the required line
Equation of the line is given by
From 1st condition:
3^(x+1)=81
Take log on both sides,
➡ log [3^(x+1)]=log81
Use the property: log(x^a)=a logx
➡ (x+1) log 3=log(3⁴)
➡ (x+1) log 3=4×log 3
➡ (x+1)=4 (log 3 /log 3)
➡ x+1=4
➡ x=3➡↪➡↪ ANS
From 2nd condition, (Same process are repeated)
81^(x-y)=3
➡ 3^4(x-y)=3
➡ log [3^4(3-y)]=log 3
➡ 4(3-y) log 3=log 3
➡ (3-y)=(log 3)/(4log 3)
➡ 3-y=(1/4)
➡ y=11/4 ➡↪➡↪ ANS
Answer:
an expression, the exponent indicates how
any times the base is used as a factor. false.
Step-by-step explanation:
beacuse i guess iam smart
<span>Every square is a rectangle. Always
</span>A<span> rectangle is any four-sided with four right angles and opposite sides are equal.
Squares has four right angles, so square is a special type of rectangle with all sides equal.

Put them into y=mx+b
y=1/3x -1
y=2/3x-4
Graph them. Where they touch is your answer. No touch? No solution. Same line? Infinite solutions.
Second set: Same thing.
Solution to first set is (9,2)
