Answer:

a) $\frac{32}{21}$

b) -14

c) -3

d) -96

Step-by-step explanation:

a) The parenthesis indicate multiplication.

b) Minus and plus gives subtraction, and the sign you put behind the number is the sign of the largest number you have (in this case it's 21 since we ignore the -)

c) They already have common denominators, all that's left is to do $\frac{-7 -2}{3} = \frac{-9}{3} = -3$

d) The parenthesis indicate multiplication.

Good luck!

Solve the equation for x. Assume a≠0. 4=ax−14

AleksAgata [21]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve for x ~

$\qquad \tt \dashrightarrow \:4 = ax - 14$

$\qquad \tt \dashrightarrow \:ax = 4 + 14$

$\qquad \tt \dashrightarrow \:ax = 18$

$\qquad \tt \dashrightarrow \:x = \dfrac{18}{a}$

What is the orthocenter of the triangle with two altitudes given by the lines x = -1 and y = x + 1. :

KonstantinChe [14]

Orthocenter is the point of concurrence of the altitudes of the triangle.

This means Orthcenter is the point where the altitudes intersect.

Here one altitude is x = -1

The other altitude is y = x + 1

Substituting x = -1 in y = x + 1

We get

y = -1-1=0

Hence the point of intersection of the altitudes is (-1,0)

The orthocenter of the triangle whose altitudes are x = -1 & y = x+1 is (-1,0)

(-1,0) which is Option c) or the third option is the right answer.

$\bf 4xy^3(3x^2y)^2\impliedby \textit{first off, distribute the exponent}
\\\\\\
4xy^3~(3^2x^{2\cdot 2}y^2)\implies 4xy^3~(9x^4y^2)\implies 4\cdot 9xx^4y^2y^3
\\\\\\
36x^{1+4}y^{2+3}\implies 36x^5y^5$
