The y-intercept of the line is the value of "y" when x=0
Therefore:
if x=0
0+4y=15
4y=15
y=15/4

Answer: A. 15/4

To find the y intercept of the line we need to know x=0

x+4y=15 The original problem.

x(0)+4y=15 X=0

4y=15 Simplified

x=3.75 or 15/4 Divide by both sides

Easy answer: A

There's your answer! Hope it helps

Simplify (x-4)(4x^2+x-6)!!!

ki77a [65]

Answer:

4x^3 - 15x^2 - 10x + 24

Step-by-step explanation:

FOIL (x-4)(4x^2+x-6)

= x(4x^2+x-6) -4(4x^2+x-6)

= 4x^3+x^2-6x-16x^2-4x+24

=4x^3-15x^2-10x+24

Ben is standing 8 feet from

never [62]

Answer:

Approximately 15.05 ft

Step-by-step explanation:

You need to use tangent for this question.

Since tan θ = $\frac{Opposite}{Adjacent}$

to find the Opposite, we need to rearrange the equation to:

Adjacent × tan θ = Opposite.

So if you insert 62 for θ and 8 feet for Adjacent, you will get:

8 × tan(62) = Opposite.

and you will get approximately 15.05 feet for your Opposite side

at an amusement park a person spends $30 on admission and food and then goes on r number of rides that cost $2 each

stepladder [879]

The question is find the equation, in the function and standard notations, that represent the amount spent in the range of 0 to 5 rides.

Constant cost: $30
Independent variable, number of rides: r
Variable cost: $2r

Total spend, s(r): 30 + 2r

Function: s(r) = 30 + 2r, for 0 ≤r ≤ 5 ----- this is the function notation

Standard form: s(r) is the dependent variable = s

s = 30 + 2r => s - 2r = 30 =>

s + (-2)r = 30, for 0 ≤ r ≤ 5 ------ this is the standard form

Quadrilateral FGHI is similar to quadrilateral JKLM. Find the measure of side JK

Stells [14]

Answer:

Heyyyy!!

The answer is 66.9

please read the explanation... it will help... I promise

Step-by-step explanation:

Okay... Here we go...

The context mentions that the two quadrilaterals are similar... meaning their sides are proportional...

So... you basically have to find the scale factor...

(the math itself is easier than the explanation...

51/16 = 3.1875 (that is the number we multiplied the sides of quadrilateral FGHI to get quadrilateral JKLM...

so to get side JK all you have to do is multiply that scale factor by side FG... which after the use of a calculator results in 66.9 (i rounded, and used a calculator... lol)

but yeah... i hope this helps...
