<span>Hello : let
Q(0,1) R(2,7)
the slope is : (YR - YQ)/(XR -XQ)
(7-1)/(2-0) = 3
an equation is : y=ax+b a is a slope</span>
y = 3X +b
the line through point Q(0,1) :
1= 3(0)+b<span>
<span>b = 1
the equation is : y =3x+1</span></span>

150⁰ +x = 180⁰
x = 30⁰
Step-by-step explanation:
1/2 × base × heinght
1/2 × 30⁰ × 90⁰
15 × 90
1350 ft² is area of triangle
Answer:
A. 0.5
B. 4.5
C. 1.5
D. 0.5
Step-by-step explanation:
y varies inversely with x can be written as:
y = k/x
where k is constant of variation.
1. value of A
x=A, y = 9 and k = 4.5 (given)
y = k/x
9 = 4.5/A
=> A = 4.5/9
=> A=0.5
2. Value of B
x =1, y= B, k = 4.5
y = k/x
B = 4.5/1
B= 4.5
3. Value of C
x=C, y=3. k=4.5
y = k/x
3 = 4.5/C
3C = 4.5
C = 4.5/3
C = 1.5
4. Value of D
x= 9, y=D, k=4.5
y = k/x
D = 4.5/9
D = 0.5
