This doesn't represent an function. Because the output is uneven to the other outputs,
1=4, 2=7 if you divided 2 into 2 parts it would equal 1=3.5 not 4.

ΔCAR has coordinates C (2, 4), A (1, 1), and R (3, 0). A translation maps point C to C' (3, 2). Find the coordinates of A' and R

shutvik [7]

Answer:

$A'= (2,-1)$ and $R'=(4,-2)$ under this translation.

Step-by-step explanation:

A translation in $R^{2}$ is a mapping T from $R^{2}$ to $R^{2}$ defined by $T(x,y) = (x + v_1,y+v_2)$ , where $v=(v_1,v_2)$ is a fixed vector in $R^{2}$ .

From the problem we know that $T(2,4)=(3,2)$ , so we need to find the values $v_1$ and $v_2$ such that $T(2,4) = (2 + v_1,4+v_2)=(3,2)$ , so $3=2 + v_1$ and $4+v_2=2$ , thus $v_1=1$ and $v_2=2$ .

Then $T(x,y) = (x + 1,y-2)$ and

$T(1,1)=(1+1,1-2)=(2,-1)=A'$

$T(3,0)=(3+1,0-2)=(4,-2)=R'$

Therefore $A'= (2,-1)$ and $R'=(4,-2)$ . The triangles CAR and C'Q'R' are shown in the figure below.

Please help! Quadratic equations!

Alexeev081 [22]

Answer:

$x^2 -2x - 35 =0$

Step-by-step explanation:

Assume that the quadratic term of this equation has no coefficient. One can set the equation up in factored form using the given roots. Then expand the equation and simplify the equation to convert to standard form.

The equation in factored form is the following,

$(x+5)(x-7)=0$

Expand, multiply every term in one of the parenthesis by every term in the other,

$(x+5)(x-7)=0\\\\(x)(x)+(5)(x)-(7)(x)+(-7)(5)=0$

Simplify,

$x^2 +5x -7x -35 =0\\\\x^2 -2x -35=0$

Sam Smith is purchasing a home. The selling price is $107,000. He is acquiring a new conventional loan and decides to make a 10%

kotykmax [81]

Answer:

$214

Step-by-step explanation:

selling price= $107,000

subtract 10%down payment

107,000- (107,000*.1)

107,000-107,00

96,300

Interest rate= 8%

Annual payment= 96,300* 0.08

$7704

per month payment= 7704/12

$624

payment on closing only for 10 days
