Answer:y=4x -7

Step-by-step explanation:

The slope intercept form is: y= mx + b

Y+3 = 4(x-1) step one distribute 4

Y+3= 4x - 4 step two subtract 3 from both sides

Y=4x -7

Please can you give me the answers to the questions above in standard form.

ivanzaharov [21]

Answer:

a) $4.5 \times 10^{11}$

b) $3.5 \times 10^{3}$

Step-by-step explanation:

a) We have to simplify the below expression in standard form.

The expression is $(5\times 10^{3}) \times (9 \times 10^{7})$

Now, $(5\times 10^{3}) \times (9 \times 10^{7})$

= $(9 \times 5) \times (10^{3} \times 10^{7})$

= $45 \times 10^{(3 + 7)}$ {Since $a^{b} \times a^{c} = a^{(b + c)}$ }

= $45 \times 10^{10}$

= $4.5 \times 10^{11}$ (Answer)

b) We have to simplify the below expression in standard form.

The expression is $(7\times 10^{5}) \div (2 \times 10^{2})$

Now, $(7\times 10^{5}) \div (2 \times 10^{2})$

= $(7 \div 2) \times (10^{5} \div 10^{2})$

= $3.5 \times 10^{(5 - 2)}$ {Since $a^{b}\div a^{c} = a^{(b - c)}$ }

= $3.5 \times 10^{3}$ (Answer)

Please explain how you would prove that all circles are similar?

NISA [10]

Answer:

Shapes are similar when one can be scaled to be like another one. Circles are always the same shape and they only vary in size. A very small circle can be expanded to be the same size as any other without changing it's shape, only size. However this is not true for ovals since they come in different shapes.
