4.2x−1.4y=2.1 in terms of y

Alona [7]

To find Y we must cancel X out by making it 0.

4.2(0) - 1.4y = 2.1

-1.4y = 2.1

Divide both sides by -1.4 to get the Y by itself.

Y = 2.1/-1.4
Y = -1.5

During a manufacturing process, a metal part in a machine is exposed to varying temperature conditions. The manufacturer of the

mars1129 [50]

Answer:

Yes, it will reach or exceed 141 degree F

Step-by-step explanation:

Given equation that shows the temperature T in degrees Fahrenheit x minutes after the machine is put into operation is,

$T = 0.005x^2 + 0.45x + 125$

Suppose T = 141°F,

$\implies 141 = 0.005x^2 + 0.45x + 125$

$\implies 0.005x^2 + 0.45x + 125 - 141 =0$

$\implies 0.005x^2 + 0.45x - 16=0$

Since, a quadratic equation $ax^2 + bx + c =0$ has,

Real roots,

If Discriminant, $D = b^2 - 4ac \geq 0$

Imaginary roots,

If D < 0,

Since, $0.45^2 - 4\times 0.005\times -16 = 0.2025 + 32 > 0$

Thus, roots of -0.005x² + 0.45x + 125 are real.

Hence, the temperature can reach or exceed 141 degree F.

AH the second question

Degger [83]

Answer:

ii. 55 degrees.

Step-by-step explanation:

(ii)

Consider the quadrilateral ABCD.

Angle n = 180 - 96 = 84 degrees ( opposite angles of a cyclic quadrilateral are supplementary).

Consider triangle ABC: the 3 angles are supplementary, so

m < j = 180 - 84 - 41

= 55 degrees.
