Answer:

π

Step-by-step explanation:

Which linear equation below represents the line that goes through the point (3.4) and has a slope of 2?
Ad libitum [116K]

Answer:

Linear equation with a slope of 2 that goes through the point (3, 4) is y = 2\cdot x -2.

Step-by-step explanation:

From statement we know the slope of the line and a point contained in it. Using the slope-point equation of the line is the quickest approach to determine the appropriate equation, whose expression is:

y-y_{o} = m \cdot (x-x_{o})

Where:

m - Slope, dimensionless.

x_{o}, y_{o} - Components of given point, dimensionless.

x, y - Independent and dependent variable, dimensionless.

If we know that m = 2, x_{o} = 3 and y_{o} = 4, the linear equation is found after algebraic handling:

1) y-4 = 2\cdot (x-3) Given

2) y = 2\cdot (x-3) +4 Compatibility with Addition/Existence of Additive Inverse/Modulative Property

3) y = 2\cdot x -2 Distributive Property/(-a)\cdot b = -a\cdot b/Definition of sum/Result

Linear equation with a slope of 2 that goes through the point (3, 4) is y = 2\cdot x -2.

Help please<br><br> Geometry test
ahrayia [7]

Step-by-step explanation:

To find x,

21x - 9 = 117

21x = 126

x = 6

To find arc AB,

21(6) - 9 = 117

To find Arc AE,

117 + x = 180

x = 63

Arc ABC,

117 + 63 = 180

ACE

180 + 27 + 90 = 297

For each of the following expressions rewrite it in a way that would make it easier to simplify. State whether you used the asso
Elis [28]
1. 15(10 - 2)....distribute....150 - 30 = 120
2. (24 + 18) + (12 + 6).....commutative....(24 + 6) + (12 + 18) = 30 + 30 = 60
3. 5 * 13 * 2.....commutative.....5 * 2 * 13 = 10 * 13 = 130
4. 94 + 17 + 53 + 6....commutative...94 + 6 + 17 + 53 = 100 + 70 = 170
5. 25(14) ...distribute..25 * 10 + 25 * 4 = 250 + 100 = 350
6. 25 * (4 * 17)...associative....(25 * 4) * 17 = 100 * 17 = 1700
