Answer:
The pair of number are (2 and 1), (2 and 2)Step-by-step explanation:
The pair of number that makes the expression [tex]a^x = ax[/tex] true are 2 and 2 as shown:
where a = 2 and x =2
2² = 2*2
2² = 4
and:
2*2 = 4
Hence 2² = 2(2) = 4 making the expression [tex]a^x = ax[/tex] true for both pair of numbers
Also the number pair 1 and 2 makes the expression correct as shown:
[tex]2^1 = 2(1)\\2 = 2 (true)[/tex]

?
Step-by-step explanation:
y = 3x - 2
x - y = 4
Answer:
x=-1, y=-5
Step-by-step explanation:
y=3x-2 (1)
x-y=4 (2)
sub (1) into (2)
x-(3x-2)=4
x-3x+2=4
-2x=2
x=-1
sub x=-1 into (1)
y=3(-1)-2
=-3-2
y = -5
Therefore: x=-1, y=-5 :))
Answer:
x = -1, y = -5
Step-by-step explanation:
y = 3x - 2
x - y = 4
x - y = 4
x - (3x - 2) = 4
x - 3x + 2 = 4
-2x + 2 = 4
-2x = 2
x = -1
x - y = 4
-1 - y = 4
-y = 5
y = -5
Check:
x - y = 4
-1 - (-5) = 4
-1 + 5 = 4
4 = 4

(? x 3) - 3 = 15
help pls and i need the steps :/
Answer:
4
Step-by-step explanation:
Lets make [tex]x[/tex] be the ? in the equation.
That becomes ([tex]x[/tex] x 3) - 3 = 15.
First you have to add 3 on both sides. After doing that it gets to ([tex]x[/tex] x 3) = 15 - 3.
Then you simplify it to 3[tex]x[/tex] = 12.
Now you divide 3 on both sides. That gets to [tex]x[/tex] = 4 after doing it.
Hope this helped! If not, please let me know! <3

Lance is solving the equation 2(2x + 1) - (3x - 5) = 17. His steps are shown below: Step 1: 4x + 2 - (3x - 5) = 17 Step 2: 4x + 2 - 3x - 5 = 17 Step 3: x + 2 - 5 = 17 Step 4: x - 3 = 17 Did Lance make a mistake? If so, in which step did he make the mistake and what was his mistake?
Answer:
Lance made a mistake
His mistake was in step 2
Step-by-step explanation:
Yes, Lance made a mistake.
He made a mistake in step 2 of his solution.
The mistake he made was that he was supposed to open the bracket of -(3x-5) to give -3x + 5
The 5 is supposed to have a positive value and not a negative

SOMEONE PLEASE HELP I NEED THE SOLUTION TO ALL OF THESEE PLEASE HELP!!!!
Answer:
The answer is below
Step-by-step explanation:
Let's work it out slowly
A)
$18.79 + $2.11 - $1.92 + $17.28
- 18.79 + 2.11 + 17.28 = 38.18
- 38.18 - 1.92 = 36.26
Ans = $36.26
B)
$7.45 + $24.45 + $74.17 + $76.52
- 7.45 + 24.45 = 31.9
- 74.17 + 76.52 = 150.69
- 150.69 + 31.9 = 182.59
Ans = $182.59
C) $98.45 - $10.63 + $2.82 - $20.26
- 98.45 - 10.63 - 20.26 = 67.56
- 67.56 + 2.82 = 70.38
Ans = $70.38
Hope you understand

Please help this fairly quick
Answer:
A) true
B) false
c) true
d) true
Step-by-step explanation:
A) angles 7 and 6 are vertical angles, which means they're equal.
so, A is True.
B) angles 7 and 5 are supplementary angles, which means they add up to 180. 135 + 55 is 190. so B is False
C) angle 7 is equal to angle 3, which is supplementary to angle 1.
so, 55 + angle 1 = 180
55 + angle1 = 180
subtract 55 from both sides of the equation
angle1 = 180 - 55
angle 1 = 125.
angles a and 4 are vertical angles, so they are equal. if you add them together that would be 125 + 125
125 + 125 = 250
so, C is True
D) angles 1 and 6 are supplementary, and angles 2 and 7. since they both add together to make 180, D is True

Use the diagram and the given angle measure to find the other three measures.
m∠1=143∘
m∠2=
m∠3=
m∠4=
Answer:
angle 2 = 37⁰
angle 3 = 153⁰
angle 4 = 37⁰
Step-by-step explanation:
I guess this refers to two intersecting lines which form 4 angles.
Angles 1 and 2 are supplementary angles whose sum is 180⁰.
Angle 1 + angle 2 = 180⁰
143⁰ + angle 2 = 180⁰
angle 2 = 180⁰ - 143⁰
angle 2 = 37⁰
Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.
Hope this helps...
Answer:
m∠1 = 143°
m∠2 = 37°
m∠3 = 143°
m∠4 = 37°

solve for x if z = m - x
Answer:
x=m-z
Step-by-step explanation:
The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z
