How many solutions does the system have? x y = 5 x y = 6 none one two infinite.

Answer:

The answer is -33.

Step-by-step explanation:

To solve the given equation we will follow the PEDMAS rule.

PEDMAS stands for :

Solving the question by PEDMAS rule :

[tex]\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 27 - 31\Big) + 40\bigg\}}}}\end{gathered}[/tex]

[tex]\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 58\Big) + 40\bigg\}}}}\end{gathered}[/tex]

[tex]\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 + 58 + 40\bigg\}}}}\end{gathered}[/tex]

[tex]\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 + 98\bigg\}}}}\end{gathered}[/tex]

[tex]\begin{gathered}{\implies{\sf{29 - \Big\{ \: 62 \: \Big\}}}}\end{gathered}[/tex]

[tex]\begin{gathered}{\implies{\sf{29 - 62}}}\end{gathered}[/tex]

[tex]\begin{gathered}{\implies{\sf{ - 33}}}\end{gathered}[/tex]

[tex]\begin{gathered} \star{\underline{\boxed{\sf{\red{ - 33}}}}}\end{gathered}[/tex]

Hence, the answer is -33.

Step-by-step explanation:

Answer:

20 cm

Step-by-step explanation:

Think of a large cone, 30 cm high, and a small cone of x height.

The scale factor of a volume of the cube of the scale factor of linear dimensions.

The cubic root of 1/27 is 1/3.

This means that the height of the small cone is 1/3 the height of the large cone.

The large cone has height 30 cm.

The small cone has height 10 cm.

30 cm - 10 cm = 20 cm

Answer: 20 cm

Answer:

16 yards gained

Step-by-step explanation:

I would add the yards that were gained first so 14 + 9

so we have 23 yards gained so far then subtract the yards loss so 23 - 7 is 16, so 16 yards were gained.

.°. Option D is correct

Answer:

x = 4

y = 2√5

z = 3√5

Step-by-step explanation:

There are 3 right triangles here, so we can create 3 expressions using Pythagoras' Theorem:

a² + b² = c²

(where a and b are the legs, and c is the hypotenuse)

smallest triangle:  x² + y² = (x + 2)²

medium triangle: (x + 1)² + y² = z²

largest triangle: (x + 2)² + z² = (x + x + 1)²

rewrite the smallest triangle expression to make y² the subject:

x² + y² = (x + 2)²

⇒ x² + y² = x² + 4x + 4

⇒  y² = 4x + 4

rewrite the medium triangle expression to make z² the subject, substituting y² = 4x + 4:

(x + 1)² + y² = z²

⇒ (x + 1)² + 4x + 4 = z²

⇒ x² + 2x + 1 + 4x + 4 = z²

⇒ z² = x² + 6x + 5

rewrite the largest triangle, substituting z² = x² + 6x + 5 and solve for x:

(x + 2)² + z² = (x + x + 1)²

⇒ (x + 2)² + x² + 6x + 5 = (2x + 1)²

⇒ x² + 4x + 4 + x² + 6x + 5 = 4x² + 4x + 1

⇒  2x² - 6x - 8 = 0

⇒  x² - 3x - 4 = 0

⇒ (x + 1)(x - 4) = 0

⇒ x = -1, x = 4

as x > 0, x = 4 only

Substitute found value for x into y² = 4x + 4 and solve for y:

y² = (4 x 4) + 4

⇒ y² = 20

⇒ y = √20 = 2√5

Substitute found value for x into z² = x² + 6x + 5 and solve for z:

z² = 4² + (6 x 4) + 5

⇒ z² = 45

⇒ z = √45 = 3√5

Answer:

first make everything inches so you have at least 62 inches and at most 73 inches, now create it.

Step-by-step explanation:

62<x<=73

Answer: 62 < x [tex]\leq[/tex] 73

Step-by-step explanation:

5 feet and 2 inches all in inches would be 62 (12 inches per foot, multiplied by five equals 60, add 2). 6 feet and 1 inch would be 73 inches (12 inches per foot, multiplied by six equals 72, add 1).

Since this inequality has words such as "more than" we have to use # < x. But since at most also applies, we have to use x [tex]\leq[/tex] #.

All her siblings are over 62 inches, so 62 < x. Remember the at most 73 inches, which would be 73 [tex]\geq[/tex] x. We can conclude that the inequalities would be expressed as 62 < x [tex]\leq[/tex] 73.

Answer & step-by-step explanation:

Look at the equation: you can rewrite it as [tex]y= x^2+4x+4 +1 = (x+2)^2+1[/tex]

Now the first term of the sum is at worst 0 (when [tex]x=-2[/tex]) so the sum is no less than 1.

Correct answer is the last option. Graph is the one in the photo, the thin red line is the axis - equation [tex]x=-2[/tex], vertex has coordinate [tex](-2;1)[/tex], Y intersect is [tex](0;5)[/tex] and has no x intercepts. extra points as needed if you want a more accurate graph, mine is sketched on paint so don't expect great quality

Step-by-step explanation:

Miss K has already graded 10 tests and is grading 9 every hour. We will add keep adding 9 starting from 10.

Mr. T has already graded 22 tests and is grading 7 per hour. We will keep adding 7 starting from 22.

Miss K: 19, 27, 36. ( Took 3 hours to reach 36 tests)

Mr T: 29, 36. (Took 2 hours to reach 36 tests)

It will take Miss K 3 hours and Mr T 2 hours to have graded the same amount of tests (36).

Answer:

A conditional statement is considered true when the antecedent and consequent are both true or if the antecedent is false. When the antecedent is false, then the truth value of the consequent does not matter; the conditional will always be true.

Answer:

r=10cm (assuming the units to be in cm ). The area of a circle is given by formula: πr2. Where, π has a constant value of ≈3.14

Answer:

Undefined

Step-by-step explanation:

Given that the equation [tex]x=-4[/tex] is a vertical line that intersects the x-axis at [tex]x=-4[/tex], there is only a change in [tex]y[/tex], but no change in [tex]x[/tex]. Thus, the rate of change is undefined since you cannot divide by 0.

Step-by-step explanation:

As we use prime factorization for 200, we get 2 × 2 × 2 × 5 × 5 = 200. So, the only prime factors of 200 are 2 and 5.

Answer:

5*5*2*2*2

Step-by-step explanation:

200 divided by 2 is 100. 100 divided by 2 is 50. 50 divided by 2 is 25. 25 divided by 5 is 5

Soln

From the above diagram

Height = h = 4cm

Let a&b = upward and downward lengths respectively.

That is:

a = 13cm

b = 16cm

recall that the formula used mathematically in solving/calculating the area of a trapezium is

Area = 1/2×(a+b)×h

Area = 1/2×(13+16)×4

Area = 1/2×(29)×4

Area = (29)×2

Area = 58cm²

Answer:

1/72

Step-by-step explanation:

Probability of getting a 4 on white cube is:

P(W) · P(4) = 1/2 × 1/6 = 1/12

P(R) · P(>4) = 1/2 × 2/6 = 1/6

multiply both probabilities:  1/12 × 1/6 = 1/72

Point in the original figure: (-7, 3)

Point in the final figure: (-2, 3)

===============================================

Explanation:

To translate 5 units to the right, we add 5 to the x coordinate. The y coordinate stays the same.

The symbolic way to write the rule would be to say [tex](x,y) \to (x+5, y)[/tex]

The original point is at (-7, 3). We add 5 to the x coordinate -7 to get -7+5 = -2. The y coordinate is 3 the whole time for both points.

That's how we go from (-7,3) to (-2,3)
