given a = 5 n b = 10

c^2 = 5^2 + 10^2

What is the value of x in the equation. 8 x - 2 y= 48 when y =4

goldfiish [28.3K]

$\qquad$ ❄️ $\boxed{\bf x = 7}\\\\$

We are given –

$\qquad$ $\twoheadrightarrow\bf 8x -2 y =48$

And also value of y's given. So, just put the value of y in the given equation.

___________________________________

$\qquad$ $\purple{\twoheadrightarrow\bf 8x -2 y =48}$

$\qquad$ $\twoheadrightarrow\sf 8x - \underbrace{2 \times 4} =48$

$\qquad$ $\twoheadrightarrow\sf 8x - 8 =48$

$\qquad$ $\twoheadrightarrow\sf 8x = 48 +8$

$\qquad$ $\twoheadrightarrow\sf 8x = 56$

$\qquad$ $\twoheadrightarrow\sf x =\cancel{\dfrac{56}{8}}$

$\qquad$ $\purple{\twoheadrightarrow\bf x= 7}$

Henceforth, value of x is 7.

Solve 3x2+7x+1=0 using the quadratic formula.

NNADVOKAT [17]

Answer:

$x=\frac{-7+-\sqrt{37} }{6}$

Step-by-step explanation:

This (±) goes between the $-7$ and $\sqrt{37}$

$3x^{2} +7x+1=0$

$ax^{2} +bx+c$

$-b$ ± $\sqrt{b^2-4ac}$ /2a

$-7$ ± $\sqrt{(7)^2-4(3)(1)}$ /2(3)

$-7$ ± $\sqrt{49-12}$ /6

$-7$ ± $\sqrt{37}/6$
