Need help rn 30 points

Ilia_Sergeevich [38]

Answer: X = ( $-\frac{5}{4}\\$ , 6)

Step-by-step explanation:

x(4x - 19) = 30

4x^2 - 19x = 30

4x^2 - 19x - 30 = 0

ax^2 + bx + c = 0

$X{1}=$ $\frac{-b+\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19+\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = 6

$X{2}=$ $\frac{-b-\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19-\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = $-\frac{5}{4}$ = -1.25

X = ( $-\frac{5}{4}\\$ , 6)

Alekssandra [29.7K]

ANSWER: a=12 b=15
Explanation: (look at work below)

4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
