Answer:
hello :
x- intercepts when x = 0 : -4y = -20 so : y = 5
y - intercepts when y = 0 : 5x = -20 so : x = -4
I would say it’s b
You can cross cancel (x-3) out of both fractions
Then you have x+2/ x times 3/4
Multiply the numerators
3(x+2)
And the denominators
x • 4 = 4x
Leaving you with 3(x+2)/4x
You can simplify it further into 3x+ 6/ 4x which is option b, though it is technically simplified with the parentheses.
Answer:
(0,-1)
Step-by-step explanation:
You look at where the line intercepts the y axis, which is at (0,-1)
Answer:
<h3>AB ≈ 70m</h3>
Step-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m
Answer:
y = 0.8x + 0.5
Step-by-step explanation:
First, find the slope using two pairs of values, (0.5, 0.9) and (0.75, 1.1):

m = 0.8
Find y-intercept, b, by substituting x = 0.5, y = 0.9 and m = 0.8 into y = mx + b
Thus:
0.9 = (0.8)(0.5) + b
0.9 = 0.4 + b
0.9 - 0.4 = b
b = 0.5
To write the equation substitute m = 0.8, and b = 0.5 into y = mx + b.
Thus:
y = 0.8x + 0.5
