Answer:
Step-by-step explanation:
<em>Find the equation of the dashed line</em>
The line pass through the points
-----> is the y-intercept of the line
Find the slope of the line m
The formula to calculate the slope between two points is equal to
substitute the values
Remember that
The equation of the line into slope intercept form is equal to
we have
substitute
<em>Find the inequality</em>
we know that
The solution of the inequality is the shaded area below the dashed line
so
Answer:
I understand there is a typo, so Belly and Billy are the same person. His age is represented as B, and Suzy's as S.
S = 19
B = 9
Step-by-step explanation:
Suzy is ten years older than Belly:
(1) S = B + 10
the next year she will be twice as old as Billy
(2) S + 1 = 2 (B + 1)
solving the system of equation (1) and (2):
Making (2) - (1):
1 = 2 (B + 1) - B - 10 => 1 = 2 B + 2 - B - 10 => 1 = B - 8 => B = 9
replacing in (1) S = 19
Answer:
Center: the middle of the circle. Radius: the fixed distance from the center to any point on the circle is called the radius.
Step-by-step explanation:
The center is a fixed point in the middle of the circle; usually given the general coordinates (h, k). The fixed distance from the center to any point on the circle is called the radius.
Answer:
A m = 48
B x = -24
C x = 16
Step-by-step explanation:
A. 1/6m - 3 = 5
1/6m = 5+3
1/6m = 8
multiply both side by 6
m = 8×6
m = 48
B. 2/3x-3 = 1/2 x-7
2/3 x - 1/2 x = -7 +3
1/6 x = -4
multiply 6 to the both side
x = -4×6
x= -24
C.x+x/2-4= x/4
x+x/2 - x/4 = 4
x + l/2 x - 1/4 x = 4
1/4 x = 4
multiply both side by 4
x= 4×4
x = 16
Width = w
d)length in term of width
w + 5
b)
2(w + w + 5) > 30
2(2w +5)>30
c)
solve
2(2w +5) > 30
4w + 10 > 30
4w > 20
w > 5
