Answer:
34
Step-by-step explanation:
We start by working out the slope. The slope is change in y over change in x, so (66-58)/(-56)-(-42) is the slope here. 66-58 is 8, and -56-(-42) is -14. -8/14=-4/7. The equation of a line in slope-intercept form is y=mx+b where b is the y intercept and m is the slope. Since the slope is -4/7, then y=-4/7x+b. We then insert any x and y pair into this equation and solve for b, the y intercept to get it. (We can do ANY pair) So, 50=(-4/7)(-28)+b.
: 50=16+b
: 50-16=b
: 34=b
So, in conclusion, the y intercept is 34. Hope this helps!
Answer:
Jamel - 110 Sister - 140
Step-by-step explanation:
We are going to work backwards. If Jamel received 30 dollars less than his sister, then the total goes down to $220. Then you divide by 2 to split the money between each equally. Now Jamel has $110 and his sister has $110. But you have to add the original $30 back to his sister's total because she got $30 more. Hence Jamel has $110 and his sister has $140.
The answer is V≈0.24m³ and it says i have to have 20 characters so here you go
Solution:
<u>Step-1: Subtract 4.3 both sides.</u>
- x/5 + 4.3 = 12.4
- => x/5 + 4.3 - 4.3 = 12.4 - 4.3
- => x/5 = 8.1
<u>Step-2: Use cross multiplication to find x.</u>
- x/5 = 8.1
- => x = 8.1 x 5
- => x = 40.5
Hence, the value of x is 40.5.
