Answer:

the answer is: Yes, the distance between a line be a decimal.

Step-by-step explanation:

" The distance between two straight lines in the plane is the minimum distance between any two points lying on the lines".

Yes, finding the distance between a line can be in decimals.

let r and s be two lines such that P(a,b) and Q(c,d) are points on the line.

then the distance between lines is given by:

$\sqrt{(a-c)^2+(b-d)^2}$

so, this square root value may come in decimal as well.

Hence, the distance between two lines can be in decimals.

System :substitution Y=x+9 3x+8y=-5

OlgaM077 [116]

3x + 8(x + 9) = -5
3x + 8x + 72 = -5
11x + 72 = -5
11x + 72 - 72 = -5 - 72
11x = -77
11x/11 = -77/11
x = -7

All you have to do for this equation is to substitute the y in the second equation with what y equals to. Then you distribute and combine like-terms.

mylen [45]

A. 2067.
6890 time .30 (30 percent) is 2067
B. 4823
inital ammount minus down payment
6890 - 2067 = 4823
C 134.08
Total ammount multiplied by percentage (0.0278)
4823 * .0278 = 134.079 per month
D.1612.81
find total paid and subtract initial ammount to find finance charge
(134.08*48)= 6435.81
6435.81-4824 = 1612.81

Samantha has 52 jelly beans. She decides that she will eat 4 jelly beans per minute, and she wants to create an expression that

IrinaK [193]

Answer:

-4x+52

Step-by-step explanation:

So we know that Samantha has 52 jelly beans and that she'll eat 4 jelly beans per minute in X minutes.

It'd be 4*x=4x

Usually, it'd be 52-4x

But you can create an equivalent

Lets say x=5

So she'd eat 20 jelly beans

52-20=32

BUT

-20+52=32

So, the answer would be D

Show steps in solving ax^2+bx+c=0

Helen [10]

Solving for A.

STEP 1 ● Add -bx to both sides.
ax^2 + bx + c + -bx = 0 + -bx
ax^2 + c = -bx

STEP 2 ● Add -c to both sides.
ax^2 + c + -c = -bx + -c
ax^2 = -bx -c

STEP 3 ● Divide both sides by x^2
ax^2 / x^2 = -bx -c / x^2
a = -bx -c / x^2

ANSWER ● a = -bx -c / x^2

Hope I helped

(Q5) Decide if the function is an exponential function. If it is, state the initial value and the base. y=3.1^x

ycow [4]

Answer:

Step-by-step explanation:

Exponential equation takes the form $y=ab^x$ where

a is the initial value ( a ≠ 0), and

b is the base ( b ≠ 1)

The equation given can be written as $y=3.1^x\\y=1*3.1^x$ . Thus, it is an exponential equation.

So a = 1 and b = 3.1

Thus we can say that the initial value = 1 and the base is 3.3
