Answer:
C
Step-by-step explanation:
1) 4x + 3(x-9) = 19
or, 4x + 3x - 27 = 19
or, 7x = 19+27
or, 7x = 46
or, x = 46/7
◆ x = 6.57
2) 2(x-4) + 5x = 3
or, 2x - 8 + 5x = 3
or, 7x = 3+8
or, x = 11/7
◆ x = 1.57
3) 60 = 8y - 3(y-10)
or, 60 = 8y - 3y + 30
or, 60 - 30 = 5y
or, y = 30/5
◆ y = 6
4) 40 + 3c = 3 + 9(c-2)
or, 40 + 3c = 3 + 9c - 18
or, 40 + 3c = 9c - 15
or, 9c - 3c = 40 + 15
or, 6c = 55
◆ c = 9.166
I hope you understand..

Answer:
Step-by-step explanation:
The x-intercept is where y is 0.
The y-intercept is where x is 0.
The x-intercept would be (-4, 0) and the y-intercept (0, 2)
Using the slope formula, (y2-y1/x2-x1), we can find the slope which is 1/2.
I’m pretty sure the answer is 1,400
Estimation is always helpful when it comes to math. By estimating, you will have a good idea with what the final answer should be before you actually get it. This way, you will hopefully be able to have a good sense of whether the answer is wrong
