Step-by-step explanation:
Answer:
x = -3, 3.5
Step-by-step explanation:
(x +3) (2x-7) = 0
Solving for x, set each factor to 0
x + 3 = 0, x = -3
2x - 7 = 0, x = 7/2 or 3.5

Find the domain and range of the following graph.
Remember that the domain is the set of all the x terms.
So in the graph shown here, notice that the x terms seem to be increasing in both a positive and negative direction and there seems to be no limit to how large or how small the x terms can get. So the x terms can be all positive and negative numbers, including decimals and fractions.
In other words, the x terms can be All Real Numbers.
So the domain is equal to the set of all real numbers or R.
The range is the set of all the y terms.
Notice that all the y terms are less than or equal to 9.
So the range is {y: y ≤ 9}.
Graph each line. Give the slope-intercept form for all standard form equations.

HELP ON #2 PLEASEEE!!!!!!!!!!!!!!!!!!!!!
Answer:
ok so i think it is H
Step-by-step explanation:
Answer:
H, would be your answer.
Step-by-step explanation:
Solving the equation in the question...
3t - 8 = 4
3t - 8 + 8 = 4 + 8
3t / 3 = 12 / 3
t = 4
So, none of the equations once solved should equal 4, to not be equivelent.
F) 3t = 12
3t / 3 = 12 / 2
t = 4
T is 4 so this is not the right answer
G) t = 4
T is 4 so this is not the right answer
H) t - 8 = 1.33(4/3 in decimal form)
t - 8 + 8 = 1.33 + 8
t = 9.33
T does not equal 4 so this is the correct answer.
J) t = 8/3 + 4/3
t = 12/3
t = 4
In this option T is still 4 so this is not the correct answer.
So, therefore your answer would be H, because it is the only one that does not equal 4.
Hope this helps!
