Answer: X = -2
Step-by-step explanation:
Answer:
The value of x = 5 answer (a)
Step-by-step explanation:
∵ There is a line parallel to the base of the Δ and intersected the other two sides formed a small Δ inside the large triangle
∴ The small Δ and the large Δ are similar
∴ Their sides are proportion
∴
∴
∴ x(2x - 1) = (x - 2)(2x + 5)
∴ 2x² - x = 2x² + 5x - 4x -10
∴ 2x² - x = 2x² + x - 10
∴ -x - x = -10
∴ -2x = -10
∴ x = -10 ÷ -2 = 5
The range should be 49. To find the range you do the highest number subtract the lowest number.
Hope this helped.
Answer:
C. x=4,y=9
Step-by-step explanation:
The given information show that
x+11y=103 (1)
9x+10y=126 (2)
Isolate x from (1)
x=103-11y
Substitute x=103-11y into (2)
9(103-11y)+10y=126
927-99y+10y=126
-89y=-801
y=9
So x=103-11x9=4
