Answer:
x=4. y= 7/2----3.5
Step-by-step explanation:
for B the answer could also he m=0, b=7/2 if you're looking for the function
if you want the alt version it could also be y=3 1/2/y=3.5
100-64=36 percent wrong
if 36% is 18 questions
then, 36/18=2
every question is 2% grade
100/2=50 questions in total
Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units
Answer:
B
Step-by-step explanation:
Dilations are the only transformations in which the shape is changed.
3(x-4)>= 5x+2
Distributing 3 on x-4
3(x)-3(4)>=5x+2
3x-12>=5x+2
Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides
-2x >=14
Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is
x<=-7
