Use slope formula: y2-y1/x2-x1
XZ: -5/9
YZ: 2/7
XY: -7/2
XYZ is a right triangle because two of these slopes have a product of -1.
(YZ and XY does). We are all busy these days.
Answer:
37
Step-by-step explanation:
To find the answer to this equation, we need to substitute 5 into where x is in the original equation.
f(x) = 8x-3
f(5) = 8(5)-3
f(5)= 40-3
f(5)= 37
and that's it! no further simplifying.
4tf = 48 in
The ratio of the table to the model table is 48:6
The ratio in simplest form is 8:1
Answer:
let width be x
Step-by-step explanation:
2x-6+3+2x-6+3=18
4x+6=18
4x=18-6
4x=12
x=12/4
x=3
Sin (Π/2 - theta) = sin(Π/2) * cos(theta) - cos(Π/2) * sin (theta)
and as we know sin(Π/2) =1 , cos(Π/2)=0
so sin(Π/2 - theta) = 1* cos(theta) - 0* sin(theta)= cos(theta)
2nd cos(180+ theta) = cos(180)*cos(theta) - sin(180)* sin(theta)
,,, so , cos(180+theta) = -cos(theta)
