Which relationship is NOT a function?
Answer:
a
Step-by-step explanation:
Answer:
If it is possible to draw any vertical line (a line of constant x) which crosses the graph of the relation more than once, then the relation is not a function. If more than one intersection point exists, then the intersections correspond to multiple values of y for a single value of x (one-to-many).

Step-by-step explanation:
Consider that:
[tex](f/g)(x) = f(x) / g(x)\\(f - g)(x) = f(x) - g(x)[/tex]Fill in the blanks
Row 1 ⇒ 2 and -5
(-1)*(-2) = 2Solve using two values:
f(x) - g(x) = - 10 and f(x)/g(x) = - 1 ⇒ f(x) = -g(x), substitute into first-2g(x) = - 10 ⇒ g(x) = 5 and f(x) = - 5Row 2 ⇒ -5 and 5

Which of the algebraic expressions below is equal to 28?
Select all that apply.(ANSWER ONLY IF YOU KNOW!)
A) (34)(20)×2
B) (24÷4)(7)
C) 9(7−3)–8
D) (3+4)⋅(22+3)
Answer:
ITS C
Step-by-step explanation:
9(7−3)−8
=(9)(4)−8
=36−8
=28
Answer:
C.
Step-by-step explanation:
9(7-3)-8
according to PEMDAS, we have to do the parenthesis first. so
9(4) - 8
then
36 - 8
which gives us 28.
Hope this helped! (:
i need to know what 26.6 divided by 7 is.
Answer:3.8
Step-by-step explanation:
Write the following as an algebraic expression.
Subtract 3x + 5 from 6x-8.
The answer is
(Simplify your answer.)
Answer:
-0.002
3x+5=6x-8
Answer:
x=1.4
Step-by-step explanation:
6x-8 -3x+5
+3x +3x
So now we have: 9x-8 5 so add 8 on both sides, leaving you with 9x on one and 13 on the other. Now divide 13 by 9, which is 1.4_ so x=1.4
Now do 3 times 1.4 plus 5 and 6 times 1.4 minus 8 and the results you get for each you will need to subtract: (result of 6x-8) - (result of 3x + 5)
GOOD LUCK!!!!!!!!

Answer:
5
Step-by-step explanation:
The whole angle is 180 degrees.
90 degrees is already taken by the angle dividing the two vertical angles.
So you have 90 degrees left. then you have to subtract 49 from 90 to get the angle of '5t+6'.
So 5t+6 = 41, 41-6 is 35. 35/5 is 5, so t is 5.
I didn't go too far into explaining since you asked to not explain it.

Answer:
...
Step-by-step explanation:
Answer:
Step-by-step explanation:
A) ∠1 = ∠2 {Alternate angles are equal}
6x + y - 4 = x - 9y + 1
6x + y = x - 9y + 1 + 4
6x + y = x - 9y + 5
6x - x + y + 9y = 5
5x + 10y = 5
Divide the entire equation by 5
x + 2y = 1 -------------(I)
∠2 + ∠3 = 180 {Linear pair}
x - 9y + 1 + 11x + 2 = 180
x + 11x - 9y = 180 - 2 - 1
12x - 9y = 177
Divide the whole equation by 3
4x - 3y = 59 -------------(II)
B) Multiply equation (I) by 3 and multiply equation (II) by 2. Thus y will be eliminated and we can find the value of x.
(I)* 3 3x + 6y = 3
(II)*2 8x - 6y = 118 {Now add}
11x = 121
x = 121/11
x = 11
Plugin x = 11 in equation (I)
11 + 2y = 1
2y = 1 -11
2y = -10
y = -10/2
y = -5
C) ∠1 = 6x + y - 4
= 6*11 - 5 - 4
= 66 - 5 - 4
= 57
∠2 = x - 9y + 1
= 11 -9*(-5) + 1
= 11 + 45 + 1
= 57
∠3 = 11x + 2
= 11*11 + 2
= 121 + 2
= 123

What is the resulting expression?
O2k4-10K2-7k-14
O-1062-7k+244-14
0 -17k2+10k4-14k-14
O 6k4-14k2 +7k-14
Answer:
-7k
Step-by-step explanation:
(−102+7k+6×4)+(−14−464−14k)
Multiply 6 and 4 to get 24.
−102+7k+24−14−464−14k
Add −102 and 24 to get −78.
−78+7k−14−464−14k
Subtract 14 from −78 to get −92.
−92+7k−464−14k
Subtract 464 from −92 to get −556.
−556+7k−14k
Combine 7k and −14k to get −7k.
−556−7k
a journey by bus takes 45 mins at 40km/h how fast must a car go to undertake the same journey in 25 mins
Answer:
72km/h
Step-by-step explanation:
Bus - 45 mins at 40km/h
Car - 25 mins at ?
First, find the distance travelled by the bus (since, the journey of the two vehicles are the same, the distance would be the same as well)
distance = speed × timedistance = 40 × 3/4 (45 mins = 3/4 of an hour (45 ÷ 60))distance = 30kmNow we can find the speed of the car using the equation
speed = distance ÷ timespeed = 30 ÷ 5/12 (25 mins = 5/12 of an hour (25 ÷ 60))speed = 72km/hcan anybody give me solving steps?
Answer:
angle relationship: same-side interior
value of x: 40
Step-by-step explanation:
the horizontal lines are parallel and the vertical line is the transversal, so 3x+x+20=180. combine the x's and subtract 20 from both sides to get 4x=160. then divide both sides by 4 to get x=40.
