Hello!
Answer:
1. x= 1 / y= 2 / z= -3 / <u>(1 ; 2 ; -3)</u>
2. x= 3 / y= -5 / z= 8 / <u>(3 ; -5 ; 8)</u>
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Because the angle with measure 82 and angle 1 are corresponding angles, their angles measure must be equal, and therefore angle 1 has measure of 82 as well. Since angles 1 and 2 are a linear pair, they must be supplementary, and angle 2 is therefore 180-82=98 degrees. Hope this helps!
Answer: Substitution
Step-by-step explanation:
Because you know A is equal to B, you can substitute A for B in any mathematical equation. Essentially, you are switching mA $ mB.
Answer:
Option D In step 4 Keith should have subtracted 5 from each side
Step-by-step explanation:
step 1
we have
f(x)=7x+5 -----> given
step 1 is correct
step 2
Change f(x) to y
y=7x+5
so
step 2 is correct
step 3
Exchange x for y and y for x
x=7y+5
so
step 3 is correct
step 4
Subtract 5 each side
x-5=7y+5-5
x-5=7y
<u><em>step 4 is not correct</em></u>
step 5
Divide by 7 each side
(x-5)/7=y
step 6
Change y to g(x)
(x-5)/7=g(x)
step 7
switch sides of the equation
g(x)=(x-5)/7
therefore
In step 4 Keith should have subtracted 5 from each side
Answer:
<h3>NO SOLUTIONS</h3>
Step-by-step explanation:
To solve this problem, first, you have to isolate x on one side of the equation.
3x/2-2>7
3x/2-2-7>7-7 (First, subtract 7 from both sides.)
7-7 (Solve.)
7-7=0
3x/2-2-7>0
3x/2-2*0-7*0>0*0 (Then, multiply 0 from both sides.)
0*0 (Solve & simplify.)
0*0=0 (undefined & no solutions)
In conclusion, there are no solutions.
