Answer:
f(x) = -3x - 2
F(0)=-2
F(1)= -5
Domain R
Range R
Step-by-step explanation:
To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.
Multiply equation 1 by 2
This will give 4x-2y=14
Now we can get rid of y by subtracting 2 from 1
This will give x=9
Plug back in to either equation, i will use equation 2
3(9)-2y=5 simplify
-2y=-22 solve
Y=11
Answer:
we divide 192 by the volume 19.5
192÷19.5=9.85 so the necklace is made of bronze
Answer:
No
Step-by-step explanation:
There can not be x and y both attached to one coefficient.
Its an isosceles triangle
angle B = 47
and triangleADB is congruent to triangle ADC
from here we can say that BD = DC
now AD is a median and also altitude
so from here we can say angle x = 90
now in triangle ADB
90+47+y=180(ANGLE SUM PROPERTY )
y= 43
