Answer:
x=3 and y=1
Step-by-step explanation:
subtract equation 2 from 1
then (2x+3y) -(2x+y) =9-7
2x-2x+3y-y =2
2y=2 therefore y=1
substitute y value in 2x+y=7
2x+1=7
2x=7-1
2x=6
x=3
Answer:
The value of X is 62 degrees
Step-by-step explanation:
The arc length L of a circle is given by formula:
L= 2(pi)(r)X / 360 (1)
where pi = 3.14, r is the radius of the circle and X the angle that produces the arc. You want the angle X so we can simplify X in equation (1)
360L=2(pi)(r)X
360L/2(pi)(r)= X
X = 360L/2(pi)(r)
We replace the radius r=9cm the arc L = 9.7 cm and pi and obtain
X = 360* (9.7 cm)/ 2(3.14)*(9cm) = 3492/56.52 = 61.78
That rounded to nearest degree is 62 degrees.
Answer:
210 in^2
Step-by-step explanation:
Answer:
no, its not
Step-by-step explanation:
you can find the decimals by dividing the numerator and the denominator
4/10 = 0.4
2/3 = 0.6666666......
so the values are obviously different
The rate of change of a linear function is
equal to the slope of the function,
Slope, m = ( y1 – y2) / (x1 – x2)
M = ( 27 – ( -8)) / ( 0 – 5)
M = -7
At ( 0, 27)
27 = 0(-7) + b
B = 27
<span>So the initial value ( 0, 27)</span>
