If x varies directly as y, then what is y when x = 4,<br> knowing that x = 60 when y = 5?
Basile [38]

Answer:  The answer would be 1/2

Step-by-step explanation:

<em>Y varies DIRECTLY as x. Find the constant of variation, k, if y = -5x </em>

<em>The first sentence is there for information, the constant is a number( 1,2,3...so on) , so the only number is -5 </em>

<em>It is a linear equation meaning equation of a straight line. </em>

<em>its form is y= mx+b, where m is the slope of the line, b is the y intercept when x=0. these info you have to memorize like your life depend on it. </em>

<em>next, y varies directly as x. If y = 15 when x = 60, find y when x = 100 </em>

<em>if y= 15, when x=60, then there is a number m such that m*y= 60 </em>

<em>or m= 60/y= 60/15 =4 </em>

<em>so the equation is y=4x. in this cause, the b=0 </em>

<em>so when x=0, y=0 </em>

<em>The distance a car travels at a constant speed varies directly as the time the car spends traveling. If a car traveled 105 miles in 3 hours, how far could the car travel in 5 hours? </em>

<em>remember that distance = speed times time. </em>

<em>or d=Vt </em>

<em>so car goes 105 miles on 3 hours </em>

<em>how far it goes in one hour? </em>

<em>if you know that, then you can tell how far it goes in 5 hours.</em>

<em>Hope I made it non tough enough</em>

<em>Please give me Brainliest</em>

Determine which equations below, when combined with the equation 3x-4y=2, will form a system with no solutions. Choose all that
svetoff [14.1K]
Two equations will not have solution if they are parallel and have different y-intercepts. Parallel lines have the same slope. In a slope-intercept form, the equation of the line can be expressed as,       
 
        y = mx + b 

where m is slope and b is the y-intercept.

Given: 3x - 4y = 2
Slope-intercept: y = 3x/4 - 1/2

A. 2y = 1.5x - 2
Slope-intercept: y = 3x/4 - 1

B. 2y = 1.5x - 1
Slope-intercept:  y = 3x/4 - 1/2

C. 3x + 4y = 2
Slope-intercept:  y = -3x/4 + 1/2

D. -4y + 3x = -2
Slope-intercept: y = 3x/4 + 1/2

Hence, the answers to this item are A and D.
