Answer:

x = - 3, x = - 2

Step-by-step explanation:

Given

y = x² + 5x + 6

To find the x- intercepts let y = 0, that is

x² + 5x + 6 = 0 ← in standard form

(x + 3)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x + 2 = 0 ⇒ x = - 2

The x- intercepts in coordinate form are

(- 3, 0 ) and (- 2, 0 )

The vertices of ABC are A(-3,5), B(-2,3), and C(-5,3). If ABC is reflected across the y-axis to produce the image A'B'C', find t

Nat2105 [25]

Answer:

$C' =(5,3)$

Step-by-step explanation:

Given

$A = (-3,5)$

$B = (-2,3)$

$C = (-5,3)$

Reflection across y-axis

Required

Find C'

For reflection across y-axis, the rule is:

$(x,y) \to (-x,y)$

So, the image of C is:

$(-5,3) \to (-(-5),3)$

$(-5,3) \to (5,3)$

Hence:

$C' =(5,3)$

What is the nth term rule of the linear sequence below?

Katena32 [7]

Answer:

4n -13

Step-by-step explanation:

notice that the difference between the adjacent terms is 4.

nth term is given by:

nth term = first term + (n-1) × difference -n is any number

= -9 + (n-1) × 4

= -9 + 4n -4

= 4n -13

In the collection of beads, StartFraction 4 Over 20 EndFraction are blue. Which model shows the percent of beads that are blue?

jolli1 [7]

Option B model shows the percent of beads that are blue.

Solution:

Fraction of beads blue = $\frac{4}{20}$

To convert it into percent multiply the fraction by 100.

$$\text {Percent of} \ \frac{4}{20}=\frac{4}{20}\times 100\%$

$$=\frac{4\times 100}{20} \%$

Cancel the common factors, we get

= 20%

$$=\frac{20}{100}$

This means total number of boxes 100 and shaded in blue color 20.

Therefore option 2 represents $\frac{20}{100}$ .

Hence option B model shows the percent of beads that are blue.
