Solve using the quadratic equation -4x² + 7x + 5 = 0

Luda [366]

Answer:

x=-0.544727

x=2.294727

Step-by-step explanation:

Given quadratic equation to solve:

-4x²+7x+5=0

To solve, use the quadratic formula

x= -b ± b² - 4ac / 2a

Substitute your values for a, b, & c and solve

x= -7 ± 7² - 4·(-4)·5 / 2·(-4)

x= -7 ± 49 - -80/-8

x= -7 ± 129/-8

Then, reduce the problem

x= -7/-8 ± 129/-8

x=-0.544727

x=2.294727

Answer CORRECTLY !!!!! Will mark brainliest !!!!

mash [69]

Answer:

g(q) = $\frac{5q}{8}$

Step-by-step explanation:

Given

- 7q + 12r = 3q - 4r

Rearrange making r the subject

Add 7q to both sides

12r = 10q - 4r ( add 4r to both sides )

16r = 10q ( divide both sides by 16 )

r = $\frac{10q}{16}$ = $\frac{5q}{8}$ , thus

g(q) = $\frac{5q}{8}$
