The answer would be 3(-4) -5 so x would be -12 -5 which would be x = -17

X= -4, so when you plug it in and solve the problem you'll get x= -17 Reason: 3(-4)= -12+ -5 Which equals -17.

Answer:

398.2 cm²

Step-by-step explanation:

The area of the whole circle is ...

A = πr²

A = π(13 cm)² = 169π cm²

The 270° sector is 3/4 of the whole circle, so its area is ...

sector area = (3/4)(169π cm²) ≈ 398.2 cm²

Answer:

Its graph has a V-shape

There are two inputs for which the output is $5$

The vertex of its graph is at $(0, -2)$

Step-by-step explanation:

we have

$y=\left|x\right|-2$

Statements

case A) The value of the function is never negative.

The statement is false

The value of the function is negative in the interval------> $(-2,2)$

case B) Its graph has a V-shape

The statement is true

See the graph

case C) There is only one input for which the output is $0$

The statement is false

There are two inputs for which the output is equal to zero

For $x=-2$ and $x=2$

case D) There are two inputs for which the output is $5$

The statement is true

For $x=-7$ and $x=7$

case E) The vertex of its graph is at $(0, -2)$

The statement is true

see the graph

Explain it too and what specific polynomial subject.

Morgarella [4.7K]

Answer:

Step-by-step explanation:

Expand the factors and compare the coefficients of like terms.

Given

(mx + 2)(3x - 5) ← expand using FOIL

= 3mx² - 5mx + 6x - 10

Compare to 12x² - 14x - 10

For the 2 to be equal, then the coefficients of like terms must be equal.

Compare coefficients of x² terms

3m = 12 ( divide both sides by 3 )

m = 4 → C
