Answer:
24
Step-by-step explanation:
∆ABC = ∆XYZ
line AB = line XY
3 = 18
18 ÷ 3
= 6
if you divide 36(line YZ) by 6(line BC), you'll also get 6
therefore, 4×6 = 24
Answer:
4s+14t
Step-by-step explanation:
2*[(s+5t)+(s+2t)]
=2*(2s+7t)
=4s+14t
Answer:
=19.66
Step-by-step explanation:
y=mx+b with m=-4/3 ;x=8 and y=9
9=-4/3×8+b
9=-32/3+b
9+32/3=b
b=19.66
Answer:
A=45 square inches
Step-by-step explanation:
First find the height using Trig
Tan(45)=x/6
x=6tan(45)
x=6
Then area of a parallellogram is base x height so
A=7.5 x 6
A=45 square inches
Answer:
Step-by-step explanation:
<u>slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
Given line: y= 2x +2
slope= 2
The product of the slopes of perpendicular lines is -1. Let the slope of the unknown line be m.
m(2)= -1
m= -1 ÷2
m= -½
Substitute the value of m into the equation:
y= -½x +c
To find the value of c, substitute a pair of coordinates.
When x= 4, y= 3,
3= -½(4) +c
3= -2 +c
c= 3 +2
c= 5
Thus, the equation of the line is y= -½x +5.
