Answer:

32.4

Step-by-step explanation:

The equation for area of a triangle is a=1/2bh. So all triangles on outside have area of a=1/2x4.5x3.5. Then you multiply what you get times 3 bc there are three triangles. Then you add that number to the area of the inside triangle. Which you find by doing a=4.5x3.9x1/2

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

Answer:

multiply 60×5 and get your answer for x then divide x by 5 and get why

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.

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).

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

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]

Answer:

answer: 32

Step-by-step explanation:

2+5*6

=32

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

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

Answer:

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

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].
