Answer:

B) {8.71}

Step-by-step explanation:

3. l.c.m=28

28×3/7=28×b-7/4

4×3=7(b-7)

12=7b-49

12+49=7b

61=7b

61/7=7b/7

8.71=b

b=8.71.

Which expression is equivalent to (4x⁵ + 11)² ?

O 16x^5 + 121

O 16x^10 + 121

⊙ 16x^10 +88x^5 + 121

O 16x^25 +88x^5 + 121

Step-by-step explanation:

Using formula :

(a + b)² = a² + 2ab + b²

so that…

(4x⁵ + 11)²

= (4x⁵)² + 2(4x⁵)(11) + 11²

= 16x¹⁰ + 88x⁵ + 121

[tex]16x^{10} +88x^{5} +121[/tex] expression is equivalent to [tex](4x^{5} +11)^{2}[/tex].

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

Given expression

[tex](4x^{5} +11)^{2}[/tex]

It is in the form of [tex](a+b)^{2} =a^{2} + 2ab+b^{2}[/tex]

[tex](4x^{5} +11)^{2}[/tex] = [tex](4x^{5}) ^{2} +2\times 4x^{5}\times11+11^{2}[/tex]

= [tex]16x^{10} +88x^{5} +121[/tex]

[tex]16x^{10} +88x^{5} +121[/tex] expression is equivalent to [tex](4x^{5} +11)^{2}[/tex].

Answer:

y = 0

Step-by-step explanation:

Parallel lines have equal slopes

Calculate the slopes of both lines and equate them

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 3 ) and (x₂, y₂ ) = (3, y )

m = [tex]\frac{y-(-3)}{3-1}[/tex] = [tex]\frac{y+3}{2}[/tex]

Repeat with (x₁, y₁ ) = (5, - 6 ) and (x₂, y₂ ) = (9, y )

m = [tex]\frac{y-(-6)}{9-5}[/tex] = [tex]\frac{y+6}{4}[/tex]

Equating the 2 expressions

[tex]\frac{y+3}{2}[/tex] = [tex]\frac{y+6}{4}[/tex] ( cross- multiply )

4(y + 3) = 2(y + 6) ← distribute parenthesis on both sides

4y + 12 = 2y + 12 ( subtract 2y from both sides )

2y + 12 = 12 ( subtract 12 from both sides )

2y = 0 , then

y = 0

Answer:

its 6.

Step-by-step explanation:

you could simplify it or cross multiply

Answer: Check whether the given ratios are equal? The given ratios 3: 5 and 15: 25 are equal. Because when you divide the ratio 15: 25 by 5 on both numerator and denominator, the first ratio 3: 5 can be obtained. Similarly, when you multiply the first ratio 3: 5 by 5, the ratio 15: 25 can be obtained.

Answer:

h = 4x+10

Step-by-step explanation:

a = b(h)

h = a/b

Sub:

a = 12x^2 + 38x + 20

b = 3x + 2

12x^2 + 38x + 20 = 3x + 2 * h

Rewrite:

h = 12x^2 + 38x + 20 / 3x + 2

Solve:

2(3x+2)(2x+5)  / 3x+2

2(2x+5) = 4x + 10

Answer:

6

Step-by-step explanation:

After divide, the solution of the expression is,

⇒ 54 ÷ 9 = 6

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 54 ÷ 9

Now, We can divide as;

⇒ 54 ÷ 9

9 ) 54 ( 6

   - 54

     ------

       00

Thus, After divide, the solution of the expression is,

⇒ 54 ÷ 9 = 6

Step-by-step explanation:

13. f(x) = 6x; f(x) = -24

6x = -24

x = -4

14. g(x) = -10x; g(x) = 15

-10x = 15

x = -1.5

15. f(x) = 3x – 5; f(x) = 4

3x-5 =4

3x =9

x = 3

16. h(x) = 14 – 8x; h(x) = -2

14-8x=-2

-8x = -16

x = 2

Answer:

y = 8x - 3

Step-by-step explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. Since we're already given the slope, 8, our equation looks like this so far: y = 8x + b.

3. We can use the formula [tex]b = y_1 - m * x_1[/tex] to find the y-intercept.

4. Since b = -3, our equation now looks like this: y = 8x - 3.

Therefore, the correct answer is y = 8x - 3.

Answer:

NOT a function

Step-by-step explanation:

y^2 (not y2) is "the square of y"

The given 2x + y^2 = 6 can be solved for y as follows:

Subtracting 2x from both sides, we get     y^2 = 6 - 2x, whose y-values are y = ±√(6 - 2x).  Because there are two y-values associated with each x value, this is NOT a function.  In a function there is only one y value for each x value.
