Answer:
A
Step-by-step explanation:
Slope Intercept form is y=mx+b where m is the slope and b is the y-intercept. The line crosses through (0,3) so b=3.
To find the slope, count the units between two points and form a ratio of vertical to horizontal distance. Count from (0,3) to (1,0). It drops -3 units and moves to the right 1 unit. So m = -3/1 = -3.
The equation is y = -3x+3
Answer:
a) 375
b) 7062.75 mm²
Step-by-step explanation:
b) We need to find the shortest possible width and length to get the smallest possible area.
To get the boundaries for 19.4, we go on to the next significant figure (the hundredths) and ± 5 of them.
The boundaries are, therefore: 19.35 - 19.45
As for the length, we can see they've added 5 units as the measurement is correct to 2 sig' figures, which is the tens.
And so, if we do as we did before, we go to the next sig' figure (the units) and ± 5 of them, we get the boundaries to be 365 - 375.
Now, we just multiply the lower bounds of the length and width to get the minimal/lower-bound area:
365 * 19.35 = 7062.75 mm²
Answer:
q = -2
Step-by-step explanation:
when solving 12q >= -24 you get
q >= -2 (12 divides 24 by 2)
therefore q is greater or equal to -2.
