374 = 33
272 = x
374/33 = 272/x
x=(33*272)/374=24 minutes
Answer:
1 Multiply the first equation by -1 then add the equations together
3. Multiply the second equation by -1 then add the equations together
4. Multiply the first equation by -2 then add the equations together
5. Multiply the first equation by 2 the second by -1 then add the equations together
Step-by-step explanation:
x+y = 7
2x+y = 5
1 Multiply the first equation by -1 then add the equations together
-x+-y = -7
2x+y = 5
---------------
x =-2 then solve for y
2. Multiply the second equation by -1 first equation by -1 then add the equations together
-x+-y = -7
-2x-y = -5
---------------
-3x -2y = -12
Still have both variables
3. Multiply the second equation by -1 then add the equations together
x+y = 7
-2x-y =- 5
----------------------
-x = 2
4. Multiply the first equation by -2 then add the equations together
-2x+-2y = -14
2x+y = 5
--------------
-y = -9
5. Multiply the first equation by 2 the second by -1 then add the equations together
2x+2y = 14
-2x-y = -5
--------------
y = 9
First, combine like terms.
12y+6=6y+12 turns into
12y-6y=12-6, which is
6y=6. Now divide both sides by 6.
y=1
now do a quick check (cause that's always a good idea).
12(1)+6=6(1)+12
12+6=6+12
18=18 ; )
<h3>Answer:</h3>
w+x+y+z = 12
<h3>Explanation:</h3>
When right angle ADC is divided into three equal parts (trisected), each of those parts is 90°/3 = 30°. Thus, ∠CDB = ∠PBD = ∠PDB = 30°.
The sides of a 30°-60°-90° triangle are in the proportion 1 : √3 : 2. Hence BD = 2, and PD = PB = 2/√3 = (2/3)√3.
Then the perimeter of ∆BDP is ...
... perimeter ∆BDP = BD + DP + PB
... = 2 + (2/3)√3 + (2/3)√3
... = 2 + (4√3)/3 . . . . . . . . w=2, x=4, y=3, z=3
w + x + y + z = 2+4+3+3 = 12
Answer:
See attachment
Step-by-step explanation:
Assuming the equation is
Then we have a transformed exponential function whose parent function is
We can see that:
There is a transformation of the form:
The parent function has been shifted to the right 4 units and down 3 units.
The is shown in attachment.
