Answer:
-2
Step-by-step explanation:
So to find slope you just subtract y^1 - y^2 and divide it by x^1 - x^2
The first point is (2, 1)
The second is (0, 5)
1 is our y^1 and 5 is our y^2
1 - 5 = -4
2 is our x^1 and 0 is our x^2
2 - 0 = 2
So our slope is -4/2, reduced its -2
I hope this helped, please mark Brainliest, thank you!
Answer:
5
Step-by-step explanation:
20+14-7-22 that is how i got 5 .
Answer:
x = -9
y = 5
Step-by-step explanation:
<u> </u><u> </u><u>7y</u><u> </u><u>-</u><u> </u><u>2x</u><u> </u><u> </u><u>=</u><u> </u><u>5</u><u>3</u><u> </u> +
-6x = 54
x = -9
(-7y) - 4(-9) = 1
(-7y) + 36 = 1
-7y = -35
y = 5
Answer:
-2<x<3
or x∈(-2,3)
Step-by-step explanation:
x²-5x<-6
add (-5/2)² i.e.,25/4
x²-5x+25/4<-6+25/4
(x-5/2)²<(-24+25)/4
(x-5/2)²<1/4
(x-5/2)²<(1/2)²
|x-5/2|<1/2
-1/2<x-5/2<1/2
Add 5/2
-1/2+5/2<x-5/2+5/2<1/2+5/2
-2<x<3
1. One face is 5.1*2.5=12.75 un^2, one is 8.5*2.5=21.25, one is 6.8*2.5=17, and two are 1/2*6.8*5.1, so both are 34.68. Total is 85.68, rounded to 85.7 cm^2. (C)
2. The area of the circles is 2(π*2^2), which is about 25.1. The rectangle's area can be found as 2π*2*3, which is about 37.7. The total is rounded to 62.8 m^2 (D)
3. Rectangular faces: 3.6*1.8=6.48, 8.5*1.8=15.3, 7.7*1.8=13.86
Triangles: 2(1/2(3.6*7.7))=27.72
Total: 63.36, round to 63.4 km^2 (B)
