In the diagram below, BC−→− bisects ∠FBE
nirvana33 [79]

Answer:

<em>m∠EBC = 34° </em>

Step-by-step explanation:

m∠DBC = m∠DBE + m∠ EBC

m∠DBC - m∠DBE = m∠EBC

(12x - 3)° - (5x + 12)° = (3x + 13)°

12x - 5x - 3 - 12 = 3x + 13

4x = 28

x = 7

<em>m∠EBC </em>= (3(7) + 13)° <em>= 34° </em>

Please help I’m confused math is hard!
Butoxors [25]

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

<em>don't forget to write the original equation first. </em>

V=2(4)(2(4)^2+5(4)+2)

<em>V=8(36+20+2)</em>

<h2><u><em>V=464 ft^2  </em></u></h2>

⬆is your answer! hope this helped!!

What is an equation in point-slope form of the line that passes through the point (8, 5) and has slope −7?
Masteriza [31]

Answer:

y - 5 = -7(x - 8)

Step-by-step explanation:

We can immediately adapt y - k = m(x - h) as follows:  replace m with -7, h with 8 and k with 5, obtaining:

y - 5 = -7(x - 8)

This is the desired equation in point-slope form.
