The answer is x >_ -2 and x >_ 7.
Answer:
15 unit
Step-by-step explanation:
Applying
/RT/ = √[(y₂-y₁)²+(x₂-x₁)²]............. Equation 1
Where /RT/ = distance between point R and Point T
From the question,
Given: y₁ = -9, x₁ = 8, y₂ = -9, x₂ = -7
Substitute these values into equation 1
/RT/ = √[(-9-(-9))²+(-7-8)²]
/RT/ = √[(0)²+(-15)²]
/RT/ = √225
/RT/ = 15 unit
Hence the distance between point R and point T is 15 unit
If there are choices, then you need to choose the correct choice, but if there are no choices, then one correct answer is to multiply the first equation by -2 and add it to the second equation to eliminate x and solve for y.
Ok so, A + B = 2 x - 2
And A - B = 4 x- 8.
Solving: A = (2x-2+4x-8)/2 = (6x-10)/2= 3x-5
B = (2x-2-4x+8)/2= (-2x+6)/2= -x+3
