Steps:
y = 4x - 9
Substitute x for y since y=x
x = 4x - 9
x - 4x = 9
-3x = -9
x = -9/-3
x = 3
Y = x
Y = 3
Check:
y = x
3 = 3 ✅
y = 4x - 9
3 = 4(3) - 9

A triangle has side lengths of
(x-8) (4x2 – 3) and (4x2 + 4).
If the perimeter is 650 units, what is the value of x?
Answers
Given:
The three sides of a triangle are:
[tex](x-8),(4x^2-3),(4x^2+4)[/tex]
The perimeter of the triangle 650 units.
To find:
The value of x.
Solution:
Perimeter of a triangle is the sum of all three sides of the triangle. So,
[tex]Perimeter=(x-8)+(4x^2-3)+(4x^2+4)[/tex]
[tex]Perimeter=8x^2+x-7[/tex]
The perimeter of the triangle 650 units.
[tex]8x^2+x-7=650[/tex]
[tex]8x^2+x-7-650=0[/tex]
[tex]8x^2+x-657=0[/tex]
Splitting the middle term, we get
[tex]8x^2+73x-72x-657=0[/tex]
[tex]x(8x+73)-9(8x+73)=0[/tex]
[tex](x-9)(8x+73)=0[/tex]
Using zero product property, we get
[tex](x-9)=0\text{ and }(8x+73)=0[/tex]
[tex]x=9\text{ and }x=-\dfrac{73}{8}[/tex]
For negative value of x, the side [tex](x-8)[/tex] will be negative, which is not possible because the side of a triangle cannot be negative.
Therefore, the only value of x is 9.

Miguel sells insurance. He earns a 6% commission on each sale he makes. Miguel has a goal of earning $600 in commissions. Miguel need to sell $ Worth of insurance to meet his goals
Answers
Answer: $12,000
Step-by-step explanation:
Miguel makes 6% on every sale he makes and wants to make $600 in commissions.
The amount he needs to sell is therefore the amount that has $600 as 5% of it.
Assume the amount of insurance needed is x.
x * 5% = 600
x = 600 / 5%
x = $12,000
what percentage is $4 of $16?

Since they have the same base (3^11 and 3^4), just 11-4 and get 7 => 3^7
Again, since the same base (3^3 and 3) just sum the exponents => 3+1=4 => 3^4
And now 3^7 : 3^4 => 7-4 is 3 => 3^3 or 27.

a guidebook says this tower is 50m tall.Is that correct? given deegrees are 27° and 46°
Answers
9514 1404 393
Answer:
yes
Step-by-step explanation:
The tower is about 50.1 meters tall. The guidebook is correct.
__
The distance from the base of the tower to the angle vertex is ...
d1 = h/tan(46°)
d2 = d1 +50 = h/tan(27°)
Then the height of the tower is ...
h/tan(46°) +50 = h/tan(27°)
50 = h(cot(27°) - cot(46°))
h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692
h ≈ 50.1544 . . . meters
The tower is more than 50 meters high.

The cost to mail a package varies directly to the weight of the package. If a 14- ounce package costs $4.48 to mail, find the weight of a package that cost $8 to mail.
Answers
Answer:
Step-by-step explanation:
Ok so first, we must figure out what 1 once costs. This can be done by divideing 4.48(cost) by 14(weight).
You should get 0.32.
Now just multiply by 8 and you should get your answer. This answer is 2.56.
Answer:
2.56
Another way this can be done is dividing 8(second weight) by 14(first weight) which will get you the difference. This is 0.5714 blah blah blah goes on for a long time. Now, take this number and multiply it by the 4.48(first cost). This should get you 2.56.
