Answer:

x= 4/9

Step-by-step explanation:

-1/(2x) + 1/8 = -1/(3x) - 1/4

-1/(2x)+1(3x)= - 1/4 -1/8

-3/(6x)+2(6x) = -2/8 -1/8

- 1/(6x) = - 3/8

-1*8 = -3*6x

8=18x

x= 8/18= 4/9

Check:

-1/(2*4/9) + 1/8 = -1/(3*4/9) - 1/4

- 1(8/9) + 1/8 = - 1/(4/3)-1/4

-9/8+1/8 = - 3/4-1/4

-1 = -1

Answer:

2z(2z+1)

Step-by-step explanation:

Write the equation for the area and then factor the polynomial to find the possible expression for the length and width.

A = 4z2 + 2z The GCF of 4z2 and 2z is 2z.

= 2z(2z) + 2z(1) Write the terms as products using the GCF as a factor.

= 2z(2z + 1) Use the distributive property to factor out the GCF. Possible expressions for the dimensions of the wall are 2z m and (2z + 1) m.

The requried expression of the length and width is (2z + 1) and 2z.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,
As mentioned in the question, the amount of paint needed to cover a wall is proportional to its area.

The wall is rectangular and has an area of 4z² + 2z square meters. According to the question, we have factored this polynomial to find possible expressions for the length and width of the wall.
So,
Area =  4z² + 2z

Takin common 2z
Area = 2z × (2z + 1)

Comparing the above expression with
Area of rectangle = width × length

From comparison,

Length = (2z + 1)
Width = 2z

Thus, the requried expression of the length and width is (2z + 1) and 2z.

Answer: 44%

Step-by-step explanation: First, let's add up all the children in the classroom...

15 + 12 = 27

There's 15 boys, therefore have to divide 15 by 27...

15 ÷ 27 = 0.55 x 100 = 55%

Now, let's divided the total amount of girls...

12 ÷ 27 = 0.44 x 100 = 44%

44 + 55 = 99%

The perecent of girls in the classroom are 44%, I hope this helps!

Answer:

The graph of the function is negative on (3,0)

Step-by-step explanation:

The limiting behavior of a function describes how a function behaves as x ⇒ ±∞. Its behavior is determined by the degree of a polynomial and the sign of its leading coefficient.

Since the function [f(x)] is an even degree polynomial with negative leading coefficient, then f(x) ⇒ -∞ as x ⇒ ±∞. The graph of the function is negative at the root. Since it has a root of 3, The graph of the function is negative on (3,0)

Answer:

The graph of the function is negative on (3, infinity) The answer is D

Answer:

(xy) (xy) (1−1) (2 3)

Step-by-step explanation:

Slope 4 intercept is -5 we can rearrange with 4x-y=5

We then work out y= -5+ 4x  and y=4x−5

We know there is a 4 intercept and we are ready in negatives -5

The slope goes up again by 4 after -1

4+-1 = 3 to find y

We find x by plugging in these values 3(-1) = 2

The required solution as ordered pairs to the given equation 4x - y = 5 are (5/4,0) and (0,-5)

A linear equation is defined as an equation in which the highest power of the variable is always one.

The equation is given in the question

4x - y = 5  ....(i)

We have to determine the ordered pair (x, y) that is a solution to the given equation.

Two that to find are (a,0) and (0,b); these points are/contain the x and y intercepts.

Substitute the point coordinate values for x and y in the equation and solve for the remaining variable.

Substituting into the given equation (i):

(a,0): 4a - 0 = 5 ⇒ a = 5/4 and (a,0) = (5/4,0)

(0,b): 4(0) - b = 5 ⇒ b = -5 and (0,b) = (0,-5)

Therefore, the required solution as ordered pairs to the given equation 4x - y = 5 are (5/4,0) and (0,-5)

x raise to 6/7

Step-by-step explanation:

since the base of both the numbers on the numerator is same,

4/7 + 3/7 = 7/7

so, x raise to 7/7

then since the base is same for the numerator and denominator,

7/7-1/7= 6/7

so x raise to 6/7

Answer:

20in^2

Step-by-step explanation:

Since you multiply the original area of the triangle by the scale factor to get the new area, you can find the original area (before dilation) by dividing the dilated triangle's area by the scale factor. Since 100 is the area of the dilated triangle, and 5 is your scale factor, you do 100/5 to get the area of the triangle before it was dilated.
