2 to 4 and 11 to 11/2 are they proportional

The X- intercept of the graph of the function at x =>-4 and x = 2.

The provided function is g(x)=-1(x-4)(x+2).

The x intercept of the function means, that point at which the graph of function will have the y coordinate as zero.

So, the x intercept of the function will be at the point where the function g(x) will be equal to zero.

g(x) = 0

-1(x-4)(x+2) = 0

(4-x)(x+2) = 0

Here,

We will get two values of x at which g(x) will be zero,

X = 4 and -2.

When a figure is dilated by a factor of 3, the statement about the image of the figure that is true is C Both the area and the perimeter decrease.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.

The x and y coordinates of the original figure are multiplied by the scale factor to discover spots on the dilated image when a dilation in the coordinate plane has the origin as the center of dilation. The algebraic representation of the dilation is (x, y) for scale factor k. (kx, ky).

In this situation, since the figure is dilated by a factor of 3, there will be a reduction. In conclusion, the correct option is C.

Answer:

Step-by-step explanation:

Drawing two marbles at once is the same as drawing one and then drawing the second  without replacing the first.

Starting with 8 red balls and 14 blue balls, the probability of drawing a red ball  is 8/22 = 4/11.

Assuming red was drawn in the first draw, the probability of getting a red ball in the second  draw means that you are  drawing from a collection containing 7 red balls and 14 blue balls, so the probability is: 7/21 = 1/3.

So when calculating the odds of the second draw, we took into account the change in the number of hits and the number of chances, so these two events are  independent and the total probability is the product of the two individual probabilities.

P(2 reds) = (4/11) (1/3) = 4/33

The probability that both marbles are red is 4/33.

It should be noted that from the information given, the jar contains 8 red marbles and 14 blue marbles.

The total marbles will be:

= 8 + 14 = 22

The probability of selecting the first red marble will be:

= 8/22 = 4/11

The probability of selecting the second red marble will be:

= 7/21 = 1/3

Therefore, the probability that both marbles are red will be:

= 4/11 × 1/3

= 4/33

The least water depth and greatest depth will be 0.97d and 1.03d.

An expression is used to show the relationship between the variables.

In this case, the depth of water d in a swimming pool increases and decreases by 3% over a one-month period.

The least water depth will be:

= d - (3% × d)

= d - 0.03d

The greatest water depth will be:

= d + (3% × d)

= d + 0.03d

The probability of winning the minimum award of $100 in the lottery is [tex]\frac{113}{140448}[/tex]

The probability of picking first winning number (out of 57 white balls) is [tex]\frac{1}{57}[/tex]

Now, out of the remaining 56 white balls, the probability of picking second winning number is [tex]\frac{1}{56}[/tex]

So total probability of the correctly matching two numbers drawn from the white balls is  [tex]\frac{1}{57} + \frac{1}{56}[/tex]

Next, to match the winning number on the gold ball, probability of this event is [tex]\frac{1}{44}[/tex]

Thus overall probability of winning the minimum award is calculated by multiplying the individual probabilities of aforesaid two independent events as follows:

The x-intercept of the function is found to be x = (y + 80)/5 and the values of x calculated are 17,18,19 and so on.

Given, the x-axis and y-axis are intersected by two intercepts, P(2,0) and Q(0,3). => 3x + 2y – 6 = 0, Consequently, the line's equation is 3x + 2y - 6 = 0. Figure.

A line's x-intercept and y-intercept are the points at which the x- and y-axes, respectively, are crossed.

The given function is:

f(x) = 5x¹ - 80

Let,

y = f(x)

∴ y = 5x – 80

  y + 80 = 5x

  (y + 80)/5 = x

∴ x = (y + 80)/5

If y = 5,

x = (5 + 80)/5 = 17

If y = 10,

x = (10 + 80)/5 = 18

If y = 15,

x = (15 + 80)/5 = 19

Thus, by substituting y values in multiples of 5, we can get x values as 17, 18, 19 and so on.

Thus, the x-intercept of the function is found to be x = (y + 80)/5 and the x values calculated are 17,18,19 and so on.

Answer:

B, D, E

Step-by-step explanation:

We can find the area of B since the height and lengths is known, so the area is just 2*4 = 8 cm^2
D also has the height and length given, it is 4*3 = 12 cm^2
E gives 3 values, but only focus on the height and length, which are 2 and 5 respectively. 3 is also a side length, but there is no height to match that length. The area of E is 2*5 = 10 cm^2

The reasons A, C, and F don't work:
A seems like it would work, until you realize that 5 is a height, not a length, and so is 2. They are both heights, and multiplying heights together won't usually get you an accurate area unless the shape is a rectangle.
C has a length, but no height. the 3 cm is pretty much an arbitrary measurement.
F has two lengths, which would only give the area if the shape was a rectangle, which it is not.

Using either method, we can conclude that x - 5 is a factor of the polynomial

This is further explained below.

Explain, based on the fact that, using either approach, whether or not we can consider x-5 to be a factor in the polynomial.

Generally, the equation for the problem is mathematically given as

f(x)=x^3-x^2-17 x-15

Therefore,  If (x-5) is factor of f(x) then at x=5 ,f(x)=0 then apply this

The number of quarters and dimes with Maria are 17 and 8 respectively.

Linear equations in mathematics are ones where the greatest power of the variable is one. A linear equation can only have one possible solution: a straight line. Thus, a simultaneous linear equation is a system of two linear equations in two or three variables that are solved concurrently to get a shared answer. Three methods are frequently used to solve simultaneous linear equations: substitution method, elimination method, and graphic method.

Let q be the number of quarters.

Let d be the number of dimes.

Given that the total amount is 5.05 in quarters and dimes

Therefore, 0.25 q + 0.10d = 5.05;

I once more, q = 2d + 1. — (ii) (ii)

Inferring from I and (ii), d = 4.80/0.60 = 8 and 0.25(2d + 1) + 0.10d = 5.05 and 0.60d = 4.80 respectively.

This is put into (ii), and the result is q = 2d + 1 = 2*8 + 1 = 17.
