Which of the following describes graphing y ≥ |x| + 4?

kolbaska11 [484]

Answer:

Translate $y=\left|x\right|$ up $4$ units and shade inside the V

Step-by-step explanation:

we know that

The function $y=\left|x\right|$ has the vertex at point $(0,0)$

The function $y=\left|x\right|+4$ has the vertex at point $(0,4)$

the rule of the translation is

$(x,y)------> (x,y+4)$

That means

The translation is $4$ units up

The solution of the inequality $y\geq\left|x\right|+4$

is the shaded area inside the V

see the attached figure to better understand the problem

therefore

the answer is

Translate $y=\left|x\right|$ up $4$ units and shade inside the V

Tamara says she used the GCF to factor the expression 21x + 56xy as 7(3x + 8xy). Is she correct? Explain.

cestrela7 [59]

Answer:

Tamara incorrectly factored the whole expression.

Step-by-step explanation:

Note that

21x=3·7·x;
56xy=2·2·2·7·x·y.

Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.

Thus,

21x+56xy=7x(3+8y).

Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.

2.3×10⁹=(1×10³)(2.3×10^n)

kotegsom [21]

Answer:

n = 6

Step-by-step explanation:

2.3 × $10^{9}$ = (1 × 10³)(2.3 × $10^{n}$ )

(1 × 10³)(2.3 × $10^{n}$ ) = (1)(2.3) × (10³)( $10^{n}$ ) = 2.3 × $10^{3+n}$

2.3 × $10^{3+n}$ = 2.3 × $10^{9}$ ⇒ 3 + n = 9 ⇒ n = 6
