Answer:
x=9
Step-by-step explanation:
.5x+.7 = .3x+2.5
-.7 -.3x
.2x=1.8
/.2 /.2
x=9
.5(9)+.7=5.2
.3(9)+2.5=5.2
Answer:
x = 3
Step-by-step explanation:
The side ratios of an isosceles right triangle are ...
1 : 1 : √2
AB : BC : AC
= 1 : 1 : √2
= 6 : 6 : 6√2 ⇒ BC = 6
The side ratios of a 30°-60°-90° right triangle are ...
BD : DC : BC
= 1 : √3 : 2
= 3 : 3√3 : 6
BD = x = 3
Answer:
y = - 3x - 22
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x + 1 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute (- 6, - 4) into the partial equation
- 4 = 18 + c ⇒ c = - 4 - 18 = - 22
y = - 3x - 22 ← equation of perpendicular line
