Answer:
x=13
Step-by-step explanation:
vertical opposite angles are equal.
The value of "b" is the y-intercept.
In order to figure out slope-intercept form you need 1 coordinate and the slope.
1) Find the slope, using the 2-point slope formula: "m= y2-y1 / x2-x1".
ex. m= -5 - 3 / -4 - -6 (simplify)---> m= -4
2) Fill in the blanks for point-slope formula: "y - y1 = m (x - x1)"
(choose one coordinate, it doesn't matter which one)
ex. y - -5 = -4 (x - -4)
3) Then use basic algebra to simplify.
5^7 = 5 × 5 × 5 × 5 × 5 × 5 × 5 = 78,125
5^-9 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.000000512
5^-5 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.00032
78,125 × 0.000000512 × 0.00032 = 0.0000128
Answer: 0.0000128 or 1.28 x 10^-5
Answer:
1. x= -66
2, x=7
3. m= -28
4. t= -2.04 (I rounded)
5. x-(-2)=21
6. x(-2.5-3)=60
7. x≥40
