Answer:
It would be true
Step-by-step explanation:
3x-7=14, add 7 both sides, 3x=21, x=7, therefore it's true. Hope this helps!
Step-by-step explanation:
A cyclic quadrilateral is a quadrilateral whose vertices all lie on a single circle. A convex quadrilateral ABCD is cyclic if and only if its opposite angles are supplementary, means
∠q + 58 =180
∠q = 180 -58
∠q = 122 degree
∠p + 90 = 180
∠p = 180 -90
∠p = 90 degree
Perimeter= 2(2x+2)+2(2x-1)
Area=(x-1)*(x-1)+(2x-1)*(x+3)
Hope it helps
Volume of the sphere is 300 m³
Step-by-step explanation:
- Step 1: Calculate volume of the sphere using the formula V = 4/3πr³, where r = d/2 = 4m
⇒ V = 4/3 × 3.14 × 4³ = 267.95 = 300 m³ (rounding off to the nearest hundredth)
Answer: C
m = slope
m = (y2 - y1) / (x2 - x1)
2 points:
(2, -4) x1 = 2 and y1 = -4
(0, 4) x2 = 0 and y2 = 4
m = (4 - (-4)) / (0- 2)
m = 8 / -2
m = -4
Equation of the line is : y = mx + b
So we got...
y = -4x + b
Then we can use any of the two points given to solve for b. I’m going to use (0, 4).
y = -4x + b
4 = -4(0) + b
4 = 0 + b
4 = b
Therefore the equation of the line is
y = -4x + 4
