Answer:
D
Step-by-step explanation:
We can substitute y = 2x + 1 in the second equation
2x + 1 = -7x + 8
Add 7x to both sides
9x + 1 = 8
Subtact 1 from both sides
9x = 7
x = 7/9
Substituing x in the first equation
y = 14/9 + 1
x rounds to 0.8
y rounds to 2.5
It's a decreasing line, so we can say this object is going slow in a constant velocity.
Answer:
Justification of 'Cost of Match , based on attendants' linear equation
Step-by-step explanation:
Yes , this linear equation might hold right in denoting total cost 'y' for 'x' people attending racing event
Given equation : y = 13x + 80
Cost 'y' is the variable dependent on explanatory variable ie no. of race attendants. So, <em>y</em> is on LHS, being determined by <em>x</em> on LHS.
80 is the autonomous constant intercept of equation, denoting fixed setup cost irrespective of no. of attendants. +13x denotes every additional attendant increases cost by 13 units (above the level of fixed cost), this is the positive slope of equation (as variables are directly related)

The exact circumference of a circle with a radius of 17 millimeters is:
B. 34
millimeters
This is because to find the circumference of a circle, we can use the formula
C = 2
r
We know that the radius is 17 millimeters.
C = 2
17
When we mutliply 2 and 17, we get 34.
C = 34
Therefore, your answer is B.
