HELP ASAP Solve for x. Show or explain your work.
Answer:
[tex]x=4.5[/tex]
Step-by-step explanation:
From AAA, both triangles in this figure are similar. Therefore, we can set up the following proportion:
[tex]\frac{x}{9}=\frac{x+3}{15}[/tex] or [tex]\frac{x}{9}=\frac{3}{6}[/tex].
Cross-multiplying, we get:
[tex]6x=9(3),\\6x=27,\\x=\frac{27}{6}=\fbox{$4.5$}[/tex].
2 + yx; use x = 6, and y = 5

9514 1404 393
Answer:
0
Step-by-step explanation:
The expression ...
[tex]f^{-1}(1)[/tex]
can be read as "the value of x that makes f(x) = 1".
We can read that value from the graph. It is the y-intercept of the function f(x):
(0, 1)
The value of x that makes f(x) = 1 is 0. That is, f(0) = 1.
[tex]\boxed{f^{-1}(1)=0}[/tex]

Given:
In a right angle triangle,
Perpendicular = 8 units
Base = x units
Hypotenuse = 17 units
To find:
The exact value of x.
Solution:
The given triangles is a right angle triangle. So, side lengths form a Pythagorean triplet.
[tex](Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]
[tex](17)^2=(x)^2+(8)^2[/tex]
[tex]289=x^2+64[/tex]
[tex]289-64=x^2[/tex]
[tex]225=x^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{225}=x[/tex]
[tex]\pm 15=x[/tex]
Side cannot be negative. So, [tex]x=15[/tex].
Therefore, the required value is [tex]x=15[/tex] and yes, the side lengths form a Pythagorean triplet, i.e., (8,15,17).

A hot air balloon is traveling at a altitude of 2400 feet. It begins to descend at a rate of 75 per minute. What is an expression that represents the rate of descent for the hot air balloon
Answer:
y=-75x+2400
Step-by-step explanation:
y is the height
-75 is the rate of change so you put that before your x
2400 is your starting value/y intercept
not very good explanation but hope this helps
The ratio of the perimeter of the rectangle ABCD to the perimeter of rectangle EFGH is 4:7. The value of x is
Answer:
x = ~8.76
Step-by-step explanation:
Since we know that the scale factor is 4:7, we can figure that 5 will be 4/7 the size of x.
4/7 = 0.571
5 / 0.571 = ~8.76

May someone please help me? This is due today and I'm confused.
Answer:
2(x - 8) = 2x - 16
2(-8) + x + x = -16 + 2x or 2x - 16
2(3x + 2) = 6x + 4
6x - 2(2x + 8) = 2x + 8
-2(-3x - 2) = 6x + 4
-2(-x + 8) = 2x + 16
-14 + 3 + 2(9) + 3x = 7 + 3x
2x + 2(2x + 2) = 6x + 2
Step-by-step explanation:
I hope this helps!
Answer:
#1 = 2x-16
#2=2(-8+x)
#3 i don't know
#4= 2(x-8)
#5=6x+4
#6=2x-16
#7=7+3x
#8=2(3x+2)
please lemme know if its correct
Suppose that Omar's marginal utility for cups of coffee is constant at 1.5 utils per cup no matter how many cups he drinks. On the other hand, his marginal utility per doughnut is 10 for the first doughnut he eats, 9 for the second doughnut he eats, 8 for the third he eats, and so on (that is declining 1 unit for each additional doughnut consumed). Suppose that coffee costs $1.00 per cup and doughnuts $1.00 each, and Omar has a budget that he can spend only on doughnuts and coffee. How large would his budget need to be before he would spend a dollar on coffee?
Answer:
$6.5
Step-by-step explanation:
The marginal utility per dollar of a commodity is obtained by:
Marginal utility of coffee = 5.5
Price of coffee = $1
The marginal utility of doughnut declines by 1 per additional unit of donut consumed :
10 / 1, 9 /1..... 1/1
Therefore , before a dollar can be spent on coffee, then the marginal. Utility of coffee should be greater than doughnut.
5.5 doughnuts will be purchased, at this time marginal utility of doughnut will be 5.5/1, the 6th doughnut will have a marginal utility of 5 which is less than that of coffee.
Cost of 5.5 donuts = $5.5
Cost of coffee = $1
Total = $(5.5 + 1) = $6.5

what is the slope intercept form x+y=-15
Answer:
y=-x-15
Step-by-step explanation:
used mathaway calculator!! probably would be useful if youre doing more question like shown. :) mark brainlest pls
To find the slope intercept form, you need to isolate y.
We need to get x on the other side of the equation.
You can do this by subtracting x from each side of the equation.
x+y-x = y
-15-x = -15-x
You get...
y = -15-x
Now you need to get the x before the -15.
So just switch them.
y = -x-15
And your done.
help please! area of rectangles and squares.
Answer:
2x squared + 25
Step-by-step explanation:
Step-by-step explanation:
area of rectangle
height×base
(2x-5)(2x-2)=
=4x^2-4x-10x+10
=4x^2-14x+10
(we get quadratic equation)
a=4 b=-14 c=10
firat find discriminant with formula:
D=b^2-4ac(-14)^2-(4×4×10)=196-160=36
now find x1 and x2 with formula:
X=(-b±√D)/2a
x1=(14+√36)/8=20/8=2.5
x2=(14-√36)/8=8/8=1
lets put values :
if we put x2 value as a base, which is 1 in given height and base, we will get 2(1)-2=0. measure of amy side can't be 0.
and if we put x2 in height, it will give us zero.
so no matter which one we put as value. we will get 0cm^2. so i think it cant be detected. im sorry if im wrong
