<span>I proceed to verify each of the cases to get the answer
</span>
using a graph tool
see the attached figures

case A)
y>x+1
y<=10
x>=0

case B)
y>=x+1
y>=10
x>=0

case C)
y>=x+1
y<10
x>=0

case D)
y<x+1
y<=10
x>=0

the answer is the case A)
y>x+1
y<=10
x>=0

Answer:

9.85

Step-by-step explanation:

$Distance=\sqrt{(x2-x1)^2+(y2-y1)^2}$

$\sqrt{(1-(-8))^2+(4-0)^2}$

$\sqrt{97}$ = 9.8488

Solve by substitution x-y=-11 y+7=-2x

Bess [88]

x - y = - 11 .............( 1 )

y + 7 = - 2x ...............( 2 )

from equation ( 1 )

x - y = - 11

x = -11 + y ...........( 3)

putting x in equation ( 2 )

y + 7 = - 2 x

y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7

3 y = 15 y = 15 / 3

putting value of y in equation 3

x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)

x = -17 / 5

check

x = -11 + y

- 17 / 5 = -11 + 13 / 5

-17 /5 = -17 / 5

Could somebody help me with this please?

katrin [286]

Answer:

1) x ≅ 51.34°

2) y ≅ 38.66°

Step-by-step explanation:

In the right triangle given in the figure

∵ The triangle has a right angle

∴ Angles x and y are acute angles and the sum of their measures is 90°

→ By using the trigonometry function tan

∵ tan(x) = opposite side to x/adjacent side to x

∵ The opposite side to x = 10

∵ The adjacent side to x = 8

→ Substitute them in the rule above

∴ tan(x) = $\frac{10}{8}$ = $\frac{5}{4}$

→ Use the inverse of tan to find x

∵ x = $tan^{-1}$ ( $\frac{5}{4}$ )

∴ x = 51.34019175

∴ x ≅ 51.34°

∵ x + y = 90°

∴ 51.34 + y = 90

→ Subtract 51.34 from both sides

∴ y ≅ 38.66°
