10⁶ is 100 times the size of 10⁴.

The wording "cell b is 100 times greater than cell a" is ambiguous, as it isn't clear what property of the cell is being referred to.

If we assume the reference is to the diameter of the cell, then choice B) is appropriate (b is 100 times a).

_____

We also consider the wording "times greater than" to be ambiguous. If b is 100 more than a, we say b is 100 greater than a. If a=1 and b=100, we would say b is 99 greater than a. In this case, b also happens to be 100 times as great as a, but greater than a by only 99 times the size of a.

Two equations and their graphs are given. Find the intersection point(s) of the graphs by solving the system. X2 + y = 0 x3 − 12

Murljashka [212]

<h3>Given</h3>

x² +y = 0

x³ -12x -y = 0

the intersection point(s) (x, y)

<h3>Solution</h3>

Add the two equations together, then factor.

... (x² +y) + (x³ -12x -y) = 0 + 0

... x³ +x² -12x = 0

... x(x +4)(x -3) = 0

Then x = {0, -4, 3}.

The corresponding y-values are

... y = -x² = {0, -16, -9}

The points of intersection are (-4, -16), (0, 0), (3, -9)

In the system -12c+3d=6 and -3c+6d=-9, which expression could you use for substitution?. A. d=-1/2c-3/2. B.c=-2d+3. C.c=1/4d-1/2

nikdorinn [45]

The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6 / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6 / : 12 ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2

line cd passes through points c(3, –5) and d(6, 0). what is the equation of line cd in standard form? 5x 3y

SOVA2 [1]

The equation of the line CD that passes through points C(3 , -5) and D(6 , 0) is 5x - 3y - 30 = 0.

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

The two-point form of the equation of a line can be used to form the equation of a line if two points are given.

$(y-y_{1} )=\frac{y_{2} -y_{1} }{x_{2} -x_{1}} (x-x_{1} )$

Substituting the values,

$(y--5 )=\frac{0 --5 }{6 -3} (x-3)$

$(y+5 )=\frac{5 }{3} (x-3)$

$(y+5 )=\frac{5 x}{3} -5$

$3(y+5 )=5x -15$

$3y+15=5x -15$

$3y=5x-30$

Meanwhile, the standard form of equation of a line is ax + by + c = 0, where a and b are the coefficients, x and y are the variables, and c is the constant term.

5x - 3y - 30 = 0

A book club charges an initial joining fee of $18.00. The cost per book is $10.25. The graph shows the cost of belonging to the

Alex73 [517]

The question doesn't show any graph, but I have included it to help you with the problem.

Answer:

The new graph will be shifted up by 3 units

Step-by-step explanation:

Graph of a Real Function

The total cost of belonging to the book club depends on one fixed cost, the initial joining fee, and a variable cost, depending on the number of books purchased. Call C the total cost and x the number of purchased books, then

$C=18+10.25x$

By giving x some values, we get the corresponding values of C and then we can plot the graph as a blue line, in the image provided below.

If the joining fee goes up by $3, the new function is

$C'=18+10.25x+3$

$C'=21+10.25x$

The graph is also shown in the image, but with a red line. We can see the graph is shifted up by 3 units in the y-axis, but the slope remains the same, as the cost per book hasn't changed
