Hello!!
Well, the x-intercept is found when y = 0, so plug in y = 0:
-7x + 3(0) = 21
-7x = 21
x = -3
Therefore, the x-intercept of -7x + 3y = 21 is -3.
Hope this helps!! Let me know if you have ANY questions.
Hello there! The axis of symmetry is the vertical line where the parabola can be divided and there are two equal halves. The vertex is on that line. The point where this occurs is all in the positive range, so that eliminates B, C, and D. (0.5, 4.25) is the vertex and 0.5 is the axis of symmetry. The answer is A. Your answer is correct.
Answer:
1/4 is your answer
Step-by-step explanation:
Answer:
x is given as -1.5. Substitute to confirm
7/9% is not 7/9 of 1, it's 7/9 of 0.01.
So, it is 0.0078
Hope this helps!
