Answer:
20 -> 10 × 2 (2 is prime)
10 -> 5 × 2 (both are prime)
So you have 2 × 2 × 5, which can also be written as 2² × 5, which is your answer. I hope this helps!
Step-by-step explanation:
Answer:
X=2
Step-by-step explanation:
We can change the left side of the equation to (x+5)² which gives us
(x+5)²=49 now to get rid of the squared we can take the square root of both sides which gets us to x+5=7 and now subtract 5 from both sides to get your final answer of x=2
I hope this helps and please don't hesitate to ask if there is anything still unclear!
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)
Answer:
A. Y=3x+2
Step-by-step explanation:
Y=mx+c
m - slope coefficient of x
and so you can easily find the slope if you are asked directly like this seen in option A.
the picture has a value of X2=-3 , X1=3 & Y1=3 Y2= 1
m = Y2 - Y1 / X2 - X1 = 1-3/-3-3 = -2/-6 = 1/3.
as you can now see, the slope from the pic which is 1/3 is less than that of option A.
