Answer: I can't see the question
Step-by-step explanation:
9.9 is the answer..............
Multiply both sides by 3/4
new equation: 8-x=7.5
subtract 8 from both sides
new equation: -x= -0.5
divide both sides by -1
final answer: x= 0.5
i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point.
So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL
ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.
Remark. Draw a picture to check the steps
2 consecutive odd positive integers....x and x + 2
x^2 + (x + 2)^2 = 130
x^2 + (x + 2)(x + 2) = 130
x^2 + x^2 + 4x + 4 = 130
2x^2 + 4x + 4 = 130
2x^2 + 4x + 4 - 130 = 0
2x^2 + 4x - 126 = 0
2(x^2 + 2x - 63) = 0
2(x - 7)(x + 9) = 0
x - 7 = 0
x = 7
x + 9 = 0
x = -9 (cant be this one because it is negative
so x = 7...and x + 2 = 7 + 2 = 9......ur 2 numbers are 7 and 9
