Answer:

Smaller number-47.5

Larger number-52.5

Step-by-step explanation:

We will make the smaller number x. If the smaller number is x, then the larger number will be equal to x+5. We also know that when we add the two numbers, we get 100. We can make the equation

x+x+5=100

100-5=95

2x=95

95/2=47.5

x=47.5

The smaller number equals 47.5 and the larger number is 47.5+5 which equals 52.5

Answer:

30 - 6{sqrt15}

Step-by-step explanation:

Determine the domain and range of the given function:

y = –x4 + 4

This is just a garden-variety polynomial. There are no denominators (so no division-by-zero problems) and no radicals (so no square-root-of-a-negative problems). There are no problems with a polynomial. There are no values that I can't plug in for x. When I have a polynomial, the answer for the domain is always:

the domain is "all x".

The range will vary from polynomial to polynomial, and they probably won't even ask, but when they do, I look at the picture:

graph

The graph goes only as high as y = 4, but it will go as low as I like. Then:

The range is "all y ≤ 4".

Answer: 25 Rides

Step-by-step explanation:

Forty (cost of pass per month) divided by 1.60 (Cost of rides) = 25 rides until the cost of the rides equals the price of the pass.

Answer:

y-10=-1(x+4)

or

y-10 = -1(x-(-4))

-------------------------

y = -x+6

Step-by-step explanation:

y - 10 = -1(x+4)

y - 10 = -x - 4

y = -x - 4 + 10

y = -x + 6

Answer:

13

Step-by-step explanation:

Use PEMDAS

1. 5-4=1

7-3=4

Now you have the equation: (2x1 + 6x4)/2

2. 2x1=2

6x4=24

Now you have the equation (2+24)/2

3. 2+24= 26

4. 26/2=13

So your answer is 13.

Make sense?

Answer:

13

Step-by-step explanation:

2(5 – 4) = 2

6(7 – 3) = 24

2 + 24 = 26

26 ÷ 2 = 13

Answer: 38 meters per second

Step-by-step explanation:

Rachel's speed is 38 m/s.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

D = -38t + 220

So, t = 1

D = -38t + 220

D = -38(1) + 220

D = -38+ 200

D = 182 m

So, v = [tex](D_0 - D_1)[/tex] / t

v = ( 220- 182) /1

v = 38 m/s

Hence, Rachel's speed is 38 m/s.

Step-by-step explanation:

The required simplified value of the given expression is 4.

Given that,
An expression is given, {[(12−36)÷(−12)]2−20}÷(−4 a simplified value of the expression is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Simplifying,
=  {[(12−36)÷(−12)]2−20}÷(−4)
=[ [-24/-12]2-20] / - 4
=[4-20] / - 4
= -16/-4
= 4

Answer:

8 seconds if tyres took 1 second each tyre as 2.5/2.5 =1

The question did specify 2 1/2 secs to fll them all up which is 1 second each x 8 = 8 sec total.

Step-by-step explanation:

2  1/2 litres = number of tyres

2 1/2 seconds taken

= if each tyre took 2 1/2 seconds the quetsion should say clear but would be

2 1/2 tyres x 2 1/2 seconds = 6.26 seconds every 2 1/2 tyres

so 8 tyres x 2 1/2 seconds = 20 seconds every 8 tyres

If the 2 1/2 seconds applied to all 2 1/2

then we need to find a multiplier for 1 tyre

Here we divide

2 1/2 / 2  1/2 = 1

8 x 1 = 8 seconds.

If y = xy + x² + 1, then when x=-1,

dy/dx = -1/2

The rate of change of a function with respect to a variable are called Derivatives.

Given that, y = xy + x² + 1

Put x = -1 we get,

y = -1y + (-1)² + 1

y = -y + 1 + 1

y = 1

Now Differentiating the given equation w.r.t x

dy/dx = xdy/dx + y + 2x

dy/dx - xdy/dx = y + 2x

dy/dx (1 - x) = y + 2x

dy/dx = (y + 2x)/(1 - x)

Put x = -1 and y = 1 we get

dy/dx = (1 + 2(-1))/(1 - (-1))

dy/dx = -1/2

Hence, y = xy + x² + 1, then when x=-1,

dy/dx = -1/2
