Answer:

The y-intercept is the point (0, -4).

Step-by-step explanation:

Recall that x = 0 at the y-intercept. Set x = 0 in 4x - y = 4, obtaining:

4(0) - y = 4, or y = -4.

The y-intercept is the point (0, -4).

Answer:

ok so first we have to convert this into y intercept

4x-y=4

-4x

-y=-4x+4

*-1

y=4x-4

so the y intercept is -4

Hope This Helps!!!

$4000 principal earning 6% compounded annually after 5 years

sergij07 [2.7K]

If $4000 is the principal, compounded annually at 6%per annum for five years, then-
Amount=principal *(1+rate/100)^5
=4000*(1+6/100)^5
=4000*(53/100)^5
=5352.90
Therefore, Compound Interest =5352.90-4000
=$1352.90

Which board geometrically represents 4x2 – 1 using algebra tiles? An algebra tile configuration showing only the product spot, w

NemiM [27]

An algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

The correct option is B.

Given

Equation; $\rm 4x^2 - 1$

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero.

Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

4x² -1 = 0 is a quadratic equation.

An algebra tile configuration showing only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

Then,

The factors of the polynomial is;

$\rm 4x^2 - 1=0\\\\ 4x^2-2x+2x-1=0\\\\ 2x(2x-1)+1(2x-1)=0\\\\(2x-1)(2x+1)=0$

Hence, an algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.
