B. Same-side interior angles

Step-by-step explanation:

Angle w and angle x lie on the same side of the transversal that cut across the two parallel lines, and are also within the two parallel lines. They are therefore regarded as same-side interior angles. Same-side interior angles are supplementary.

Answer:

x+y=4

Step-by-step explanation:

No solution means that the lines will never intersect. We know that the slope of line A is -1, and it's y intercept is 2. If you look at the last option for the answer choices, it's slope is also -1, but it's y intercept is at 4. These lines have the same slope, also known as parallel, so they will never intersect, thus giving no solution

Answer:

The number of bulbs planted in the garden having side length of 8 feet is 320.

Step-by-step explanation:

Given as :

The side length of square shaped garden = x ft

The number of tulip bulbs Cindy's will plant at per square foot = n = 5

Let The number of bulb to be panted for side length of garden = L = 8 feet

Now, According to question

Since the garden is of square shaped ,

So, The area of garden = area of square = side²

I,e The area of garden = x × x ft²

Now, if the side length = L = 8 feet

So, The area of garden = L × L ft²

I.e The area of garden = 8 × 8 ft² = 64 square feet

Now, Again

∵ For the area of 1 square feet , the number of bulbs planted = 5

∴  For the area of 64 square feet , the number of bulbs planted = 5 × 64

I.e  For the area of 64 square feet , the number of bulbs planted = 320

Hence The number of bulbs planted in the garden having side length of 8 feet is 320 . Answer

Answer:

the number of blonde hair is 10

Step-by-step explanation:

The computation of the number of blonde hair is shown below;

Given that

Ratio of blonde to brunetees is 2:3

And, there is total of 25 students

So, the number of blonde hair is

= 25 × 2 ÷ (2 + 3)

= 25 × 2 ÷ 5

= 10

Hence, the number of blonde hair is 10

Answer:

(i)(a - 2y) (3x - 4b)

(iii) (m - n)(m + 4)

Step-by-step explanation:

(i)

3ax - 6xy + 8by - 4ab

= 3x (a - 2y) - 4b (-2y + a)

= 3x (a - 2y) - 4b (a - 2y)

= (a - 2y) (3x - 4b)

(iii)

The value of f(10)+10 for the given function is 32.

The given functions are  f(x) = 3x-8 and g(x) = -x²+ 4x-11.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

1) Put x=10 in the function f(x) = 3x-8, we get

f(10)=3(10)-8

= 22

So, f(10)+10

= 22+10=32

2) Put x=-9 in the function g(x) = -x²+ 4x-11, we get

g(-9)=-(-9)²+4(-9)-11

= -81-36-11

= -128

So, g(-9)+7

= -128+7

= -121

3) Put x=4 in the function g(x) = -x²+ 4x-11, we get

g(4) = -(4)²+4(4)-11

=-16+16-11

=-11

Now, -2xg(4) =-2x(-11)

=22x

4) Put x=-4 in the function f(x) = 3x-8, we get

(-4)=3(-4)-8

= -20

Put x=7 in the function g(x) = -x²+ 4x-11, we get

g(7)=-(7)²+4(7)-11

= -49+28-11

= -32

5. Given f(x)= 9 –2x, if f(x)= 19

Now, 9-2x=19

⇒ -2x=10

⇒ x=-5

Therefore, the value of f(10)+10 for the given function is 32.

Answer:

5.5

Step-by-step explanation:

6 feet =12

6 feet = 6x2

11 feet shadow 11/2

answer=5.5

The height of the diane when the height of euardo and diane cast should be given so it should be 5.5.

Since

HEIGHT Eduardo is 6 feet tall and casts a 12-foot shadow. At the same time, Diane casts an 11-foot shadow.

So,

6 feet tall = 12

Now for 11 foot it should be half like 5.5

Hence, The height of the diane when the height of euardo and diane cast should be given so it should be 5.5.

Step-by-step explanation:

4 by the power of 1 x 3

The correct step to translate f(x) = 3ˣ to g(x) = 3ˣ⁺¹ + 4 is:

Shift f(x) = 3ˣ one unit to the right and four units up. So option C is correct

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

This means that for every x value,

we add 4 to the y-value and move the y-value one unit to the right.

To see this graphically, imagine a graph of the equation f(x) = 3x.

This graph will be a line that passes through the origin (0,0) and has a slope of 3.

If we shift this line one unit to the right, then the x-intercept (the point where the line crosses the x-axis) will change from (0,0) to (1,0).

If we also add 4 to the y-value of every point on this line,

then the y-intercept (the point where the line crosses the y-axis) will change from (0,0) to (0,4).

The resulting graph will be the graph of the equation g(x) = 3ˣ⁺¹ + 4.

Answer:

  (x, y) = (3, 7)

Step-by-step explanation:

If you divide the second equation by 2, it becomes ...

 -x +2y = 11

Adding this to the first equation gives you the value of y:

  (x -y) +(-x +2y) = (-4) +(11)

  y = 7 . . . . . . . . simplify

The first equation can be rearranged to give an expression for x:

  x = y -4

  x = 7 -4 = 3

Then the solution is seen to be (x, y) = (3, 7).

Answer:

Step-by-step explanation:

x+y=14

y=14-x

2x+3y=32, using y=14-x we have

2x+3(14-x)=32

2x+42-3x=32

-x+42=32

-x=-10

x=10, and since y=14-x

y=14-10=4
