Answer:

[5, -8] + [0, -5] + [-7, 0] + [0, -6] = [-2, -19] --> III. Quadrant

[-2, 6] + [0, 3] + [5, 0] + [0, 4] = [3, 13] --> I. Quadrant

[0, -5] + [-5, 0] + [0, 4] + [7, 0] + [0, -3] = [2, -4] --> IV. Quadrant

Evaluate (98 x 102) by using suitable identities.

GREYUIT [131]

Answer:

The answer is 9996

Step-by-step explanation:

Using the identity (x+a)(x+b) = x ^2 +(a+b)x+ab

Writing 102 as 100+2 and 98 as 100−2

Hence (100+2)(100−2) = 100 ^2 +[2+(−2)]100+(2)(−2)

= 10000+(0)100−4

= 9996

The answer is 9996

PLEASEEE HURRYYY

Answer:

(2,-5) and (2,1).

Step-by-step explanation:

We need to find the find all the points having an x coordinate of 2 whose distance from the point (-2,-4) is 5.

A circle with center (-2,-4) and radius 5 represents all the points whose distance from the point (-2,-4) is 5.

Standard form of a circle is

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

where, (h,k) is center and r is the radius.

$(x-(-2))^2+(y-(-4))^2=(5)^2$

$(x+2)^2+(y+2)^2=25$

Now, put x=2.

$(2+2)^2+(y+2)^2=25$

$(4)^2+(y+2)^2=25$

$(y+2)^2=25-16$

$(y+2)^2=9$

Taking square root on both sides.

$y+2=\pm\sqrt{9}$

$y+2=\pm3$

$y+2=-3\text{ or }y+2=3$

$y=-5\text{ or }y=1$

So, the y-coordinates of the points are -5 and 1.

Therefore, the required points are (2,-5) and (2,1).

Solve −x+5≤4 or 2x+3≥−1 and write the solution in interval notation.

serg [7]

Answer:

Step-by-step explanation:

$\left \{ {{-x+5\leq 4} \atop {2x+3\geq -1}} \right.$ ⇒ $x\geq 1\\2x\geq 4\\x\geq -2$

$x \geq -2\\(-2,+ { \infty} )$ (Answer)

Marge bought a computer for $699 on the installment plan. The terms of the plan were a down payment of $100, then payments of $5

german

The answer would be $796 because your down payment is $100 plus the fact marge had to pay $58 for 12 months there for equaling $696 dollars for the 12 month then adding your down payment of $100 giving you your answer of $796!
