Answer:

A = 1, B = 1

Step-by-step explanation:

From the question

(2x+1)/(x²+x) = A/x + B/(x+1)

(2x+1)/(x²+x) = [A(x+1)+(Bx)]/(x²+x)

Equation the numerator

2x+1 ≡ A(x+1) +Bx

2x+1 ≡ Ax+A+Bx

From the above,

A = 1.

And,

2x = Ax+Bx................ Equation 1

A+B = 2

Substitute the value of A into Equation 1

1+B = 2

B = 2-1

B = 1

A function is shown: f(x) = 16x2 − 1. Choose the equivalent function that best shows the x-intercepts on the graph.
adoni [48]

Answer:

Step-by-step explanation:

f(x) = 16x² - 1

The x-intercepts are the roots, i.e., the values of x for which f(x) = 0.

Use the Quadratic Formula to determine the roots.

x = [0±√0²-4·16(-1)]/[2·16] = ±√64/32 = ±8/32 = ±¼

f(x) = 16(x-¼)(x+¼) = (4x-1)(4x+1)

Write the equation in slope intercept form with a slope of -3 and passes through (1,4)
vichka [17]
Y = mx + b, where m = slope, and b = y-intercept.

Since you are not given the y-intercept, you have to solve for it through the equation, y = -3x (which is the slope you are given) + b, and replace x and y with values given, which are (1,4)

y = -3x + b
4 = -3(1) + b
4 = -3 + b
7 = b

Then replace b in the first equation to get the answer
y = -3x + 7

in a kettle there are 8/5 litres of water a cup holds 1/5 of a litre of water how many cups can be filled with the water in the
stepan [7]

If you were to solve this equation with fractions with the same denominater, you only need to pay attention to the numerater.


you have 8/5 liters to fill 1/5 containers, 8 goes in to 1 8 times, therefore you can fill the cup eight times.


The answer is 8

Each figure shows a triangle with one of its angle bisectors.
OLga [1]

Answer:

m<2 is 17 degrees

Step-by-step explanation:

We can see that the angle at the vertex E was bisected to give two different but equal angles

Thus, we have it that;

2x + 7 = 4x-3

4x-2x = 7+ 3

2x = 10

x = 10/2

x = 5

so m<2 = 4(5) -3 = 20-3 = 17 degrees
