Answer:
y = (5/4)x+3
Step by step explanation:
y = mx + b
m = 5/4
b = 3
y = (5/4)x+3
Answer:
0.7
Step-by-step explanation:
<u>Take the scale factor as Z.</u>
9 x Z = 6.3
14 x Z = 9.8
7 x Z = 4.9
<u>Find Z</u>
6.3/9 = 0.7
9.8/14 = 0.7
4.9/7 = 0.7
Z = 0.7
Answer:
k=5
Step-by-step explanation:
1/3 of 15 is five or 15/3=5 and so the equation comes out to be k=5
Answer:
The number is 37
Step-by-step explanation:
The given parameters are;
The unit digit of a two-digit number = 4 + The tens digit
2 × The two-digit number = 1 + The reversed number
Let x represent the unit digit and y represent the tens digit, we have;
x = 4 + y
2 × yx = xy + 1
Which gives;
2 × yy+4 = 2y2y+8
xy + 1 = 4 + yy + 1
y + 1 = 2y + 8 - 10 (we assume that the product of 2 and the unit digit is more than 10 so we subtract 10 from the product to equate the unit digits of the two numbers
10 + 1 - 8 = 2y - y
10 - 7 = y
y = 3
x = y + 4 = 3 + 4 = 7
x = 7
Therefore, the number = 37.
Answer:
The required inequality is 
.
Step-by-step explanation:
The given inequalities are
where, x is the driver's age (in years), A(x) is driver’s reaction time to audio stimuli and V(x) is his or her reaction time to visual stimuli, 16 ≤ x ≤ 70.
We need to find an inequality that can be use to find the x-values for which A(x) is less than V(x).
Combine like terms.
where, 16 ≤ x ≤ 70.
Therefore, the required inequality is .
