7.	Find the point of intersection of two lines:x+2y=10 and 2x-3y=7
Answer» Answer: 2x+3y=10………(i) 3x+2y=5 ……….(ii) USING elimination method, we COULD express the value of x in terms of y and WHOLE number. using equation (i) x=-(3/2)y+10……(III) using the value of x according to equation (iii) -3(3/2)y+2y=5….(iv) solving (iv) -4.5y+2y=5….(V) -2.5y=5, solving for y you get y=-2.5 now replace y in either equation (i) or (ii) 2x+3(-2.5)=10……(vi) 2x=10+7.5…………(vii) 2x=17.5…………….(viii) x therefore is equal to 8.75. the line would intersect at (8.75, -2.5)

Find the point of intersection of two lines:x+2y=10 and 2x-3y=7

Answer»

Answer:

2x+3y=10………(i)

3x+2y=5 ……….(ii)

USING elimination method, we COULD express the value of x in terms of y and WHOLE number. using equation (i)

x=-(3/2)y+10……(III)

using the value of x according to equation (iii)

-3(3/2)y+2y=5….(iv)

solving (iv)

-4.5y+2y=5….(V)

-2.5y=5, solving for y

you get y=-2.5

now replace y in either equation (i) or (ii)

2x+3(-2.5)=10……(vi)

2x=10+7.5…………(vii)

2x=17.5…………….(viii)

x therefore is equal to 8.75.

the line would intersect at (8.75, -2.5)

31.

1. (3)

Answer»

Step-by-step explanation:

${4}^{4} = {4}^{k - 2}$

Since the BASES are the same, set the exponents equal

$4 = k - 2$

Move variables to the left-hand side and CHANGE its sign

$- k + 4 = - 2$

Move CONSTANT to the right-hand side and change its sign

$- k = - 2 - 4$

Calculate the difference

$- k = - 6$

Change the SIGNS on both sides of the equation

Solution :

$k = 6$

3. Find the roots of the following equation:1/x+4-1/x-7=11/30

Answer»

Step-by-step EXPLANATION:

${\dfrac {1}{x}}+4-{\dfrac {1}{x}}-7={\dfrac {11}{30}}$

Let's take it to simplest form

${:}\longrightarrow$ ${\dfrac {1+4-1-7}{x}}={\dfrac {11}{30}}$

${:}\longrightarrow$ ${\dfrac {5-8}{x}}={\dfrac {11}{30}}$

${:}\longrightarrow$ ${\dfrac {-3}{x}}={\dfrac {11}{30}}$

Now USE CROSS multiplication method

${:}\longrightarrow$ $30×(-3)=11x$

${:}\longrightarrow$ $11x=-90$

$\therefore$ ${{\underline{\boxed{\bf {x={\dfrac {(-90)}{11}}}}}}}$
