brian is 6 feet tall and cast a 4 foot shadow. At the same time, a nearby flag pole cast a 20 foot shadow. How tall is the flag
tresset_1 [31]

Answer:

30

Step-by-step explanation:

Given:

Brian Height = 6 feet

Brian Shadow Height = 4 foot

Flag Shadow Height = 20 foot

Flag Height = Unknown ??

So we can use cross multiplication

6/4 = x/20

6×20/4 = x

6×20 =120

120÷4 = 30

So x= 30, which is the Flag Height

I wish that I helped you with this.

Which expressions represent the difference of exactly two expressions? Choose 3 answers: Choose 3 answers: (Choice
Ket [755]

Solution

To find out which expressions represent the difference of exactly

two expressions

a) 6(x+7) - 2

This can be simplified as

6x + 42 - 2

6x + 40

Clearly this does not represent difference of the two

expressions .


b) -2j

Clearly this represents a single expression , this does not represent

a difference of 2 expression .


c) 4f - 2g

Here we have 2 different expressions 4f and 2g

Difference of these 2 expressions are 4f - 2g

Hence , this option represent difference of exactly two

expression


d) 3xyz - 10

3xtz - 10 represnts a single expression

Here we have a single expression

Therefore it does not represent difference of exactly 2

expression .

Describe in words and symbols the end behavior of f(x)=−5x4
weqwewe [10]

Answer:

The graph is attached below.

Step-by-step explanation:

Given the function

f\left(x\right)=-5x^4

Since the leading term of the polynomial (the term in a polynomial that contains the highest power of the variable) is -5x⁴,  then the degree is 4, i.e. even, and the leading coefficient is -5, i.e. negative.

This means that f(x) → −∞  as x → −∞ and f(x)→−∞  as x→∞.

The graph is attached below.

Create a system of linear equations that has one solution. Solve the system using substitution to prove your
bezimeni [28]

Answer:

y = -2x + 3

y = -1/2x + 5

Step-by-step explanation:

  • So the best way to solve is to come up with two slopes, I'd prefer 2 perpendicular slopes because perpendicular lines only cross once hence one solution guaranteed
  • so say we choose a slopeA = 2 and slopeB = -1/2, the slopes are perpendicular only if when you multiply them you get -1
  • then we use the slope intercept form of an equation y = mx + b
  • we make up two equations y = -2x + b and y = -1/2x + b , now we can just make up number for b so the two equations are
  • y = -2x + 3
  • y = -1/2x + 5
  • Then we solve them by substituting for y so
  • -1/2x + 5 = -2x + 3 and x = -4/3
  • and then we put this to get y in either equation
  • y = -2(-4/3) + 3
  • y = 17/3
  • So the equations work
