The line of 2x + 3y= 4 and passes through the point (1, -4) is equal to y= -2/3x - 10/3 that equation written in standard form is 2x/3 + y= -10/3
Answer:
1. not equal, 2. equal, 3. 18
Step-by-step explanation:
7/5 =1.4
15/10=1.5
1.4 does not equal 1.5
6/8=.75
15/20=.75
.75 equals .75
1.2*3/2=1.8
Answer:
Step-by-step explanation:
83.33To do that we divide 5 / 6, which gives us approximately 0.83333, now we multiply it by 100 since percentages are parts of 100.
Let y = x^2 - 1
x^2 = y + 1
x = sqrt(y + 1)
so f^-1(x) = sqrt (x + 1) (answer)
Answer:
<u>39.28cm^2 </u>
Step-by-step explanation:
Simple work out the area of a circle and halve it.
3.142xr^2
3.142x5^2 = 78.55 cm^2 (Full circle area)
Now we must halve that answer to get the semicircle.
78.55/2 = 39.275 cm^2
However, we need it to 2dp. Therefore the answer is 39.28cm^2
