Answer:
g=8
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
1 A= pi 21^2
2 C=pi 21
3 A= pi 10.5^2
4 C= 2pi 10.5
Step-by-step explanation:
Answer:
x<7
Step-by-step explanation:
4(5−2x)−3x>8x−113
−11x+20>8x−113
−11x+20−8x>8x−113−8x
−19x+20>−113
-20 -20
-19x>-113
/-19 /-19
(flip the sign)
x<7
i can't do the greater than or equal to sign so just remember to add that in :)
Answer:
(See explanation for further details)
Step-by-step explanation:
The expression is transformed into its standard form:
The function does not represent a circle, as radius is a positive number.
Step-by-step explanation:
Equation of straight line: y=mx+b
Given slope=2, hence m=2
y=2x+b
Replace y and x values as stated in the question (-1, -2)
(-2)=2(-1)+b
-2+2=b
b=0
rewrite the equation:
y=2x+0
y=2x
For 3) a solid line is used when the equation is <= or => while dotted line is for when the equation is < or >
Could you elaborate on question 2? I dont quite get what the question is asking for
