Answer:

The answer is C )  y^2 - 5

Step-by-step explanation:

Y is being squared, not two. So y^2. And since it is saying "5 less than y squared" and not the other way around, 5 is going to be the second factor in the equation.

Answer:

2^12

Step-by-step explanation:

16^3 = (2^4)^3 = 2^(4x3) = 2^12

Hope this helps!

Answer:

2¹²

Step-by-step explanation:

= 16³

We'll divide 16 into the product of its prime factors

= ( 2×2×2×2)³

There are four 2s so it becomes 2⁴

= (2⁴)³

= 2⁴ˣ³

= 2¹²

Answer:

5

Step-by-step explanation:

Let's call the original number x.

So, the first student did x+23, and the other student did x-1.

You know that the first students result was 7 times larger than the other students. So, you can make the equation:

x+23=7(x-1)

x+23=7x-7

Then, do the algebra

-6x=-30

x=5

Answer:

5

Step-by-step explanation:

let the number =x

x+23=7(x-1)

x+23=7x-7

7x-x=23+7

6x=30

x=30/6=5

Answer: The system has no solutions because it is inconsistent.

Step-by-step explanation:

This system is an " inconsistent system", this is because each equation:

y = 2 and y = -3

give us a different value for the same variable y (each variable can have only one value at the same time)

So this system is inconsistent, which means that the system has no solutions.

Answer:

5x=5(20)=20 for Ed

2x=2(20)=40 for pete

together they had 140 cars

Step-by-step explanation:

5:2 is the ratio

5x-30=2x+30 tat when Ed gave Pete 30 cars

solve for x

5x-2x=30+30

3x=60

x=20

substitute for x: 5x=5(20)=20 for ED

                           2x=2(20)=40 for pete

Answer:

x = 85 Degrees

y = 85 Degrees

Step-by-step explanation:

20 Degrees + 90 Degrees -->

90 and 20 are given => 110 Degrees

e triangle angles sum = 180 Degrees

180 - 110 = 70 Degrees

=> Vertical angles so 25 + x + 70 = 180

x = 85

x + (z) = 180 e sum of half 360

85 + z = 180

z = 95 Degrees

--> z + (y) = 180 e same as above (sum of interior angles)

95 + y = 180

y = 85

Answer:

The A) ΔABC ≅ ΔEDC

Step-by-step explanation:

The AAS congruence method requires 2 angles and their un-included side to be congruent. ∠A ≅ ∠E due to the markings, ∠C ≅ ∠C because they are vertical angles, and AB ≅ ED due to the markings. 2 angles and their un-included side are congruent.

As for the congruence statement, A is the correct answer because ∠A ≅ ∠E, ∠B ≅ ∠D, and ∠C ≅ ∠C. The order of the naming of the triangles aligns to the angle's congruence.

Answer:

A) triangle ABC is congruent to triangle EDC

Step-by-step explanation:

The AAS method of proving congruence of triangles uses two angles and a non-included side of the triangle. If two angles and the non-included side of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

Let's see what we have in this problem:

<ACB and <ECD are congruent since they are vertical angles.

<A and <E are congruent by given.

Sides AB and ED are non-included sides and are congruent.

Since we have two angles and a non-included side of a triangle and the corresponding parts of another triangle, the triangles are congruent by AAS.

Now we need the statement of congruence.

Angles ACB and ECD are corresponding angles, so the letter C must appear in both triangles in the same position.

Angles A and E are corresponding angles, so the letters A and E must appear in both triangles the same position.

We already have CA and CE. The last angles left are corresponding angles B and D, so we get triangle CAB and triangle CED. Since a triangle may be named using any order of the vertices, we can rename the triangles ABC and EDC and maintain the same corresponding vertices.

Answer: A) triangle ABC is congruent to triangle EDC

Option B

Step-by-step explanation:

The coordinates are (-1,8) and (3,-4)

Slope = [tex]\frac{rise}{run}[/tex]

Slope = [tex]\frac{-4-8}{3+1}[/tex]

Slope = [tex]\frac{-12}{4}[/tex]

Slope = -3

Answer:

Option B is the right option.

Solution,

Let the points be A and B

A(-1,8)-----------> (x1,y1)

B(3,-4)------------->(x2,y2)

Now,

[tex]slope = \frac{y2 - y1}{x2 - x1} \\ \: \: \: \: \: \: \: \: = \frac{ - 4 - 8}{3 - ( - 1)} \\ \: \: \: \: \: \: \: = \frac{ - 4 - 8}{3 + 1} \\ \: \: \: \: \: \: \: = \frac{ - 12}{4} \\ \: \: \: \: = - 3[/tex]

Answer:

27 Oz of 25% alcohol

Step-by-step explanation:

--percent ---------------- quantity

Alcohol I 30 ---------------- 18 Oz

alcohol II 25 ---------------- x Oz

Mixture 27 ---------------- 18 + x Oz

30*18+25x=27(18+x)

540+25x =486+27 x

Answer:

459

Step-by-step explanation:

First line:

clock showing 9 o'clock + clock showing 9 o'clock + clock showing 3 o'clock = 9 + 9 + 3 = 21

Second line:

The calculators look exactly the same.

3 * calculators = 30

1 calculator = 10

Third line:

1 bulb + 1 bulb - 1 bulb = 15

Since 1 bulb - 1 bulb = 0, we have 1 bulb + 0 = 15, or

1 bulb = 15

Last line:

Clock showing 9 o'clock = 9

Calculator = 10

3 bulbs = 3 * 15 = 45

Total = 9 + 10 * 45 = 9 + 450 = 459

Answer:

120c²d - 1200cd² -10c + 100d

The equivalent value of the expression is given by A = 20c/d = 20cd⁻¹

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

A = ( 10c⁶d⁻⁵ ) ( 2c⁻⁵d⁴ )   be expression (1)

On simplifying , we get

A = 20c⁶d⁻⁵c⁻⁵d⁴

From the laws of exponents , we get

mᵃ×mᵇ = mᵃ⁺ᵇ

So , on further simplification , we get

A = 20c⁶⁻⁵d⁵⁺⁴

A = 20cd⁻¹

A = 20c/d

Therefore , the value of A is 20c/d

Hence , the exponential value of expression is A = 20c/d

Answer:

1) 34 + 0i

2) 9/17 + (2/12)i

3) z = -i

Step-by-step explanation:

(5 + 3i)(5 - 3i) = 25 - 15i + 15i - 9i²

25 - 15i + 15i - 9i² = 25 - 9i²

25 - 9i² = 25 - 9√(-1)²

25 - 9√(-1)² = 25 - 9(-1)

25 - 9(-1) = 25 + 9

25 + 9 = 34
