Answer:

Option B.

$a$

Step-by-step explanation:

Given:

-3( -x + a ) + 7 < 5 When x = -1

To Find:

a ?

Solution:

-3( -x + a ) + 7 < 5 When x = -1

Substitute x = -1 in above we get

-3(-(-1) + a ) + 7 < 5

-3(1 + a) < 5 - 7

Using Distributive Property we get i.e A(B+C) = AB + AC

$\therefore -3\times 1 +(-3)\times a$

jon spends 2/8 of his money on food 1/5 of his money on fuel and 2/10 of his money on clothes Estimate what fraction of his mone

andrey2020 [161]

First, you have to make them into decimals to make it easier. 2/8 equals 0.25.
1/5 and 2/10 equal 0.2. 0.2+0.2+0.25 equals 0.65 so if you suppose Jon's money is 1 dollar, he has 35 cents left. In a fraction, 0.35 is 35/100. If you simplify 35/100, it's 7/20.

Answer: Jon has 35/100 or 7/20 or his money left.

What are the center and radius of the circle defined by the equation x^2 + y^2 -6x + 4y + 4=0

Sloan [31]

The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - a coordinates of the center

r - a radius

$x^2+y^2-6x+4y+4=0\ \ \ |-4\\\\x^2-2\cdot x\cdot3+y^2+2\cdot y\cdot2=-4\ \ \ |+3^2\ |+2^2\\\\\underbrace{x^2-2\cdot x\cdot3+3^2}_{(a-b)^2=a^2-2ab+b^2}+\underbrace{y^2+2\cdot y\cdot2+2^2}_{(a+b)^2=a^2+2ab+b^2}=-4+3^2+2^2\\\\(x-3)^2+(y+2)^2=3^2$
