Answer:

y=6. &. x = -10

Step-by-step explanation:

if 4x + 5y = -10

then 4x = -10 -5y. ---------->(1)

if 4x + 3y = -22

then 4x = -22 -3y. ------------>(2)

from equation (1) & (2) :

then -10 -5y = -22 -3y

then 22 -10 = 5y -3y

12 = 2y

then y=6

substituting in (1) or (2):

then. x= -10

Consider the line y=10 x -1 and the point P=(2,0). (a) Write the formula for a function d(x) that describes the distance between
LuckyWell [14K]

Answer:

the formula for a function d(x) that describes the distance is d(x)=\sqrt{101x^{2}-24x+5}

Step-by-step explanation:

We are going to define final point P_{f}=(2,0), and initial point P_{i}=(x,y)=(x,10x-1), then we can use d=\sqrt{(x_{f}-x_{i})^{2}+(y_{f}-y_{i})^{2}}, so we obtain d(x)=\sqrt{(2-x)^{2}+(0-(10x-1))^{2}}, by developing it d(x)=\sqrt{(2-x)^{2}+(0-(10x-1))^{2}}\\d(x)=\sqrt{4-4x+x^{2}+(1-10x)^{2}}\\d(x)=\sqrt{4-4x+x^{2}+1-20x+100x^{2}}\\d(x)=\sqrt{101x^{2}-24x+5}\\

This formula describes the distance between those two points and involves x

Root 8 multiple root 50
Makovka662 [10]
\sqrt{8} \times  \sqrt{50}

=  \sqrt{4 \times 2} \times  \sqrt{25 \times 2}

=  2\sqrt{2} \times  5\sqrt{2}

= 10(\sqrt{2})^2

= 10(2)

= 20
