Identify an equation in slope-intercept form the line parallel to y=-3x+7that passes through (2,-4)

gregori [183]

Answer:

y=-3x+2

Step-by-step explanation:

Same slope = parallel. You can aso double check this answer by either graphing using the desmos online graphing calculator or by plugging in the point into the equation y = -3(2) + 2 --> y = -6 + 2 --> y = -4, so we are correct.

Answer:

${7a^{5}b^{5} c\\$

Step-by-step explanation:

$\frac{28a^{8}b^{6} c^{3} }{4a^{3}bc^{2} }$

→ First look at the first term of each expression and see if they can be simplified, and they can

$\frac{7a^{8}b^{6} c^{3} }{a^{3}bc^{2} }$

→ Now look at the a terms, since a larger one is at the top, you subtract

$\frac{7a^{5}b^{6} c^{3} }{bc^{2} }$

→ Now simplify the b and c terms

${7a^{5}b^{5} c$

Answer:

Average speed is 48 km per hour

Step-by-step explanation:

A student drove to the university from her home and noted that the odometer reading of her car increased by 16.0 km. The trip took 20.0 min. (a) What was her average speed? in km/hr

Distance traveled is 16 km and the time taken is 20 minutes

convert minutes into hour. to convert minutes into hour we divide by 60 because 1 hour = 60 minutes

$\frac{20}{60} =\frac{1}{3}$

so time = 1/3 and distance = 16

Average speed = distance by time

$speed =\frac{16}{\frac{1}{3} } =\frac{48}{1}= 48$

Average speed is 48 km per hour

How do you find the radius of a circle with a circumference of 12pi

sergejj [24]

Answer:

Step-by-step explanation:

The circumference of a circle is $2\pir$ $\pi r$ , so $12\pi=2\pi r\\12=2r\\r=6$ . We can use this because the area of a circle is $\pi r^2$ . Thus, $\pi*6^2=36\pi$ .
