Answer:
N(h) = 2h + 6
Step-by-step explanation:
A model of the number of people that Denis can invite to his party:
N(x) = x/25.............(1)
Where x = amount of money saved
Amount of money saved can be modeled by the equation:
M(h) = 50h + 150...........(2)
In the above model, h = number of overtime hours
M(h) = amount of money saved = x
Therefore equation (1) can be re - written as:
N(x) = M(h)/25.................................(3)
Substituting equation (2) into equation (3)

Find an explicit expression that models the number of people that Denis can invite to his party if he worked h overtime hours this week can be expressed as:
N(h) = 2h + 6
To find arc WY:
360 - 156 - 86
arc WY = 118
To find angle WXY
118 / 2 = 59 degrees
Two ratios are 3:4 and 18:24
Step-by-step explanation:
Let the digit at tens place of a two digits number be X
The place value of X = 10×X = 10X
The units digit = 5 more than its tens digit
= X+5
The place value of units digit
= (X+5)×1
= X+5
Now
The two digits number
= 10X+X+5
⇛ 11X+5
Therefore ,The two digits number = 11X+5.
Answer:
Step-by-step explanation:
eq of circle is (x-h)²+(y-k)²=r²
where (h,k) is center of circle and r is the radius.
given eq. of circle is (x+10)²+(y-4)²=100
or {x-(-10)}²+(y-4)²=10²
center is (-10,4)
and radius =10 units
