Answer: 1/4

Step-by-step explanation: i just took the quiz

Answer:

  x - 4y = 0 . . . in standard form

  y = (1/4)x . . . in slope-intercept form

Step-by-step explanation:

The slope of the given line is ...

  m = (y2 -y1)/(x2 -x1) = (9 -(-7))/(-1 -3) = 16/-4 = -4

The slope of the perpendicular line is the negative reciprocal of this:

  desired slope = -1/m = -1/-4 = 1/4

This can be used in the point-slope form of the equation of a line:

  y -h = m(x -k) . . . . . line with slope m through point (h, k)

Your perpendicular line has a slope of 1/4 and goes through point (4, 1), so its equation can be written as ...

  y -1 = (1/4)(x -4)

  y = (1/4)x -1 +1

  y = (1/4)x

In standard form, this is ...

  4y = x

  x -4y = 0

Answer:

if he drove 9 hours it would 378 miles

The time Juan would take to travel 336 miles if he drove 126 miles in 3 hours is 8 hours.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

Given:

Juan drove 126 miles in 3 hours,

Calculate the number of hours he takes to drive 1 mile,

1 mile = 3 / 126

336 miles = 3 / 126 × 336

Therefore, The time Juan would take to travel 336 miles if he drove 126 miles in 3 hours is 8 hours.

B:It has 2 terms and a degree of 3

Step-by-step explanation:

Hope this helps!

The polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2, so option A is correct.

A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.

Given:

3x²y² − 5xy² − 3x²y² + 2 x 2

Simplify the above expression,

3x²y² − 5xy² − 3x²y² + 2 x 2 = -55xy² + 4

As you can see from the expression, it has the two-term and highest degree of 2

Therefore, the polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2.

Answer:

The answer is that it is a rational number because it is a terminating decimal

Step-by-step explanation:

0.62581 is a rational number.

Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers.

Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.

Now the given number is,

0.62581

Now here we see that the numbers after decimal are terminating and non-repeating.

Also the digit after decimal stops.

Hence the number 0.62581 is rational.

Answer: -8 degrees

Step-by-step explanation:

Answer:

We have two rates, A and B.

If we want that the units of A can be converted into the units of B, then we must have that the units of A represent the same measure that the units of B.

What does this mean?

For example, if A is written in distance over time, then B must also must have units of distance over time.

An example would be:

units for distance = meter, kilometer, feet, etc.

units for time = hour, minute, second, etc-

Then we could have:

[A] = [km/h]

[B] = [m/min]

Then the units of A could be converted into the ones of B, because both of them have the same physical meaning.

Concluding, you only can convert units that represent the same physical quantity, for example, if you have one quantity in meters, for example:

10m

You only can convert this to other units of distance, remember to do the correct conversion, if we would want to write this in cm, you should remember that:

1m = 100cm

Then, 10 times one meter is 10 times 100 cm

10m = 10*(1m) = 10*(100cm) = 1000cm

Strategy

Joe needs the rooms he's already reserved plus the additional rooms to be at least 505050. We can represent this with an inequality whose structure looks something like this:

\left( \text{rooms already reserved} \right) + \left( \text{additional rooms} \right) [\leq \text{or} \geq] \,50(rooms already reserved)+(additional rooms)[≤or≥]50left parenthesis, start text, r, o, o, m, s, space, a, l, r, e, a, d, y, space, r, e, s, e, r, v, e, d, end text, right parenthesis, plus, left parenthesis, start text, a, d, d, i, t, i, o, n, a, l, space, r, o, o, m, s, end text, right parenthesis, open bracket, is less than or equal to, start text, o, r, end text, is greater than or equal to, close bracket, 50

Then, we can solve the inequality for BBB to find how many additional blocks Joe needs to reserve.

Hint #22 / 4

1) Which inequality?

Joe has already reserved and paid for \blueD{16}16start color #11accd, 16, end color #11accd rooms.

Each blocks has 888 rooms, and BBB represents the number of additional blocks, so the number of additional rooms from these blocks is \greenD{8B}8Bstart color #1fab54, 8, B, end color #1fab54.

The number of rooms he's already reserved plus the additional rooms needs to be \maroonD{\text{greater than or equal to }} 50greater than or equal to 50start color #ca337c, start text, g, r, e, a, t, e, r, space, t, h, a, n, space, o, r, space, e, q, u, a, l, space, t, o, space, end text, end color #ca337c, 50 rooms.

\begin{aligned} \left( \blueD{\text{rooms already reserved}} \right) &+ \left( \greenD{\text{additional rooms}} \right) [\leq \text{or} \geq] \,50 \\\\ \blueD{16}&+\greenD{8B} \maroonD{\geq} 50 \end{aligned}

Subtract 16

Divide by 8

​

Since he can't reserve partial blocks, Joe needs to reserve 555 additional blocks. And each block costs \$900$900dollar sign, 900, so buying 555 additional blocks costs 5 \cdot \$900=\$45005⋅$900=$45005, dot, dollar sign, 900, equals, dollar sign, 4500.
