Answer 1

Answer:

Step-by-step explanation:

One

v^2 - 16

This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.

The square root of v^2 = v

The square root of 16 = 4

You get (v + 4)(v - 4)

Let's see what happens when you expand it.

v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16

Look what happens when you add these 4 terms together.

v^2 - 4v + 4v - 16v^2 - 16

is what is left. The two middle terms cancel out.

Two

This one is a perfect square

w^2 + 16w + 64

(w + 8)(w + 8)

Notice both factors are the same. You might wonder how I new that.

w^2 is a perfect square so take the square root.  ....   v      

64 is a perfect square so take the square root    .....    8

Now you have to work backwards to see if it is right.

w*w = w^2w*8 = 8w8*w = 8w8^2 = 64

Adding you get w^2 + 16w + 64 which is what you started with.

Answers

Answer:

D.

Step-by-step explanation:

To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.

What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5

B.

left = -5 - 5 = -10

right = -(2/3)(4 + 4) = -16/3

So it's D. Let's verify:

D.

left = -5 + 5 = 0

right = -(2/3)(4 - 4) = 0

Checks out.

Answer:

Option D

Step-by-step explanation:

→ Find the gradient of the parallel line

[tex]y=-\frac{2}{3} x+c[/tex]

→ Substitute in the coordinates as x and y values to find c

[tex]5=-\frac{2}{3} *-4+c[/tex]

→ Simplify

[tex]5=\frac{8}{3} +c[/tex]

→ Minus  [tex]\frac{8}{3}[/tex]  from both sides to find c

[tex]c = \frac{7}{3}[/tex]

→ Expand out all options and then see which one contains all the numbers above

Option D

ax^2 + bx + c = 0

A quadratic function has the possibility of two x-intercepts.

What is a quadratic function?

A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.

Given that a function having two x-intercepts

The graph of a quadratic function will always have one y-intercept and can have as many as two x-intercept.

Find the value of a and b.
2x + 5y = 9
3x – 2y = 4
x= ?
y= ?

Answers

2x + 5y = 9
3x - 2y = 4

1) Make the x equal the same (find common factor) which is 6
2) Time the whole equation by the factor for example 2x3= 6, times the top equation by 3. The bottom 3x2=6, times the bottom equation by 2:

6x+15y=27
6x-4y=8
(Cancel the x)

Left with: 19y =19 (15- -4y =19y) (27-8=19)
Therefore y = 1

Now substitute y=1 into the equation to find x

6x + 15(1)= 27
6x + 15 = 27
6x = 12
X = 2

Answers:
X=2, Y=1
