Answer:
Step-by-step explanation:
The straight line passes through (0,1) and (2,-2).
Equation of a straight line passing through two points (x1,y1) and (x2,y2)
is given by:
Everything to the left of the line is shaded.
We have to visualize the graph:the straight line has a positive y-intercept and a negative slope.The graph is given in the attachment below.
From the figure we can see origin lies on the shaded region.Hence (0,0) should satisfy the inequality.
LHS=y=0
RHS=
LHS<RHS as 0<1
Hence , the inequality is:
Answer:
Amina practices the piano for 54 minutes each week.
Step-by-step explanation:
45% * 120min = 0.45 * 120min = 9/20 * 120min = 9 * 6min = 54min
Answer:
Circumference is 43.98 inches
Step-by-step explanation:
Circumference = 2πr
= 2×3.14 ×7
= 43.98
First convert the percent to decimal form by moving the decimal point two places to the left which equals 0.08. Then multiply that by the sale price of the TV pre tax ($640.00) which equals 51.2. Finally add 51.2 to the sale price of the TV which equals $691.20.
Answer:
6.7 km
Step-by-step explanation:
c² = 4.9²+4.5²
= 24.01 + 20.25
= 44.26
c = √44.26 = 6.7
