Answer:
1. Add 5 to both sides
2. Divide both sides by 2
3. Take the square root of both sides
4. Subtract 2 from both sides
Step-by-step explanation:
2(x+2)²-5=93
<em>Add 5 to both sides</em>
2(x+2)²=98
<em>Divide both sides by 2</em>
(x+2)²=49
<em>Square root both sides</em>
x+2=7
<em>Subtract 2 from both sides</em>
x=5
Answer:
ok in this case will represent the height with a the bells with b and the hypotenuse with c so it will be c squared is equals to a squared plus b squared 12 squared + 5 squared is equals to c squared 12 square is 144 while 5 squared is 25 when added it is 169 so csquared is equals to 169 to get c we find √ 169 source is equals to 13
I think it’s 61, I’m sorry if I get it wrong. Not a 100% sure
Answer:
Slope of the line 
Step-by-step explanation:
Given that,
The point 
lies on the curve 
.
If 
is the point lies on 
.
To find:- Find the slope of line 
.
So,
The coordinates of point when it lies on
if 
then 
So, ≡ 
and many points can be calculated by given Equation.
Using the formula when two points 
.
Then, substituting the coordinates we get,
⇒ 
Therefore,
Slope of the line 
Answer:
Son's Age: 11
Mary's Age: 33
Step-by-step explanation:
Let set Mary and her son as variables,
M = Mary's age
S = Mary's son age
<u>Breakdown:</u>
"Mary is three times as old as her son"
M = 3S
"In <em>12 years</em>, Mary's age will be one less than <u>twice her son's</u> age"
M <em>+ 12</em> = <u>2</u>(S <em>+ 12</em>) - 1
we add 12 to both sides as it will be in 12 years for both
We know that M = 3S, so we plug this in
3S + 12 = 2(S + 12) - 1
Now solve for <em>S (son's age),</em>
3S + 12 - 12 = 2(S + 12) - 1 - 12
3S = 2(S + 12) - 13
3S = 2S + 24 - 13
3S - 2S = 2S - 2S + 24 - 13
S = 24 - 13
S = 11
To find <u>Mary age</u>, plug in her son age ,
M = 3S
M = 3(11)
M = 33
