What is the point -slope form of a line with slope -4 that contains the point (-2,3)

Arada [10]

Answer:

y - 3 = -4 (x +2)

Step-by-step explanation:

Point slope form is

y -y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line

y - 3 = -4 (x - -2)

y - 3 = -4 (x +2)

What are the solutions to the quadratic equation (5y + 6)2 = 24?

nata0808 [166]

Answer:

see explanation

Step-by-step explanation:

Given

(5y + 6)² = 24 ( take the square root of both sides )

5y + 6 = ± $\sqrt{24}$ = ± 2 $\sqrt{6}$ ( subtract 6 from both sides )

5y = - 6 ± 2 $\sqrt{6}$ ( divide both sides by 5 )

y = $\frac{-6+2\sqrt{6} }{5}$ and y = $\frac{-6-2\sqrt{6} }{5}$

Does anyone know the answer

Alex_Xolod [135]

Answer:x = 12,5

using thales's theorem, we have:

$\frac{15}{15+36}=\frac{20}{6x-7}\\\\ 6x-7=\frac{20.(15+36)}{15}=68\\\\x = \frac{68+7}{6}=12.5$
