Answer:
a
Step-by-step explanation:
Domain means the change in x.
so the domain will be which values of x the fn goes through.
you can see the black line goes from -9 to 2 in x values.
the -9 isn't filled in, but the 2 is. filled in means it will be with an equals instead of without.
so x is between -9 and 2, 2 is with equals -9 is without,
so the first one.
Answer:
<u>2nd row</u>
Step-by-step explanation:
The y-intercept corresponds to the ordered pair having an x-value of 0. The second row of the table has an x-value of 0, and y-value of 2. Therefore, the y-intercept is (0, 2).
All the points if they lay on top of eachother
if they arent on top of eachother, they can intersect at 2 points
Answer:
Step-by-step explanation: if you are doing subtitution then
Let's solve your system by substitution.
y=4x+14 and y=6x+8
Rewrite equations:
y=4x+14;y=6x+8
Step: Solvey=4x+14for y:
y=4x+14
Step: Substitute4x+14foryiny=6x+8:
y=6x+8
4x+14=6x+8
4x+14+−6x=6x+8+−6x(Add -6x to both sides)
−2x+14=8
−2x+14+−14=8+−14(Add -14 to both sides)
−2x=−6−2x−2=−6−2
(Divide both sides by -2)
x=3
Step: Substitute3forxiny=4x+14:
y=4x+14
y=(4)(3)+14
y=26(Simplify both sides of the equation)
Answer:
x=3 and y=26
Answer: x= -2/5 or x= -0.4
combine like terms on left side and get -11+2x. then combine terms on right side and get -13-3x. add the 11 to the right side and get 2x= -2-3x
then add over the 3x and get 5x=-2
and finally divide the -2 from 5x and get -2/5
