Find the midpoint of points A (5,-6) and B(2,0) graphically

The estimated total,costs,y, of a child's toy is practally based on the number of batteries used x.The cost of one battery is 0.

Firdavs [7]

Answer:

y = 0.75x + 12

Step-by-step explanation:

The estimated total cost, y, of a child's toy is partially based on the number 1 point of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?

y = 12x + 0.75

y = 0.75x + 12

y = 12x − (775

y = 0.75x − 12

y = total cost of a child's toy

Cost of each battery = $0.75

Number of batteries = x

Cost of the toy = $12

Therefore,

total cost of a child's toy = Cost of the toy + Cost of each battery * Number of batteries

y = 12 + 0.75 * x

y = 12 + 0.75x

y = 0.75x + 12

Write an equation of the line that passes through (-4,-1) and is perpendicular to the line y=4/3x+6

Sonja [21]

Answer:

$y=-\dfrac{3}{4}x-4.$

Step-by-step explanation:

If needed line is perpendicular to the line $y=\dfrac{4}{3}x+6,$ then its slope satisfies condition

$m\cdot \dfrac{4}{3}=-1\Rightarrow m=-\dfrac{3}{4}.$

Then the equation of needed line will have look

$y=-\dfrac{3}{4}x+b.$

Since this line passes through the point (-4,-1), then

$-1=-\dfrac{3}{4}\cdot (-4)+b,\\ \\-1=3+b,\\ \\b=-1-3=-4.$

Hence, the equation is

$y=-\dfrac{3}{4}x-4.$

Convert 6.1212 into a rarional number

Ahat [919]

in short, we will start off by making the left-side of the dot and the recurring numbers a variable, say "x", then multiplying it by some power of 10 that moves the recurring numbers over to the left, let's do so

$\bf x = 6.\overline{12}~\hspace{10em} \begin{array}{llll} 100\cdot x&=&612.\overline{12}\\\\ &&606+6.\overline{12}\\\\ &&606+x \end{array} \\\\\\ 100x=606+x\implies 99x=606\implies x = \cfrac{606}{99}\implies x = \cfrac{202}{33}\implies x = 6\frac{4}{33}$
