Answer:
[6, 18]
Step-by-step explanation:
the first matrix has the dimensions 1 x 2 (1 row, 2 columns). The send has the dimensions 2 x 2. Because of this it is possible to do matrix multiplication and the result will be a 1 x 2 matrix.
Multiply the column -2, 7 by the row 4, 2:
We get (-2)(4) + (7)(2), which simplfies to 6. This is the first element of the 1 x 2 product.
Multiply the column 5, -1 by the row 4, 2: We get (5)(4) + (-1)(2), or 18.
The fourth answer choice is the correct one: [6, 18]

What value does the red dot represent on the number line?
The red dot on the number line represents the value [tex]\(\frac{4}{5}\)[/tex], corresponding to option C.
In a fraction, the numerator (4) denotes the number of parts considered, while the denominator (5) indicates the total number of equal parts in one whole.
Thus, [tex]\(\frac{4}{5}\)[/tex] signifies four parts out of five, placing the red dot closer to the whole number 1 but not reaching it.
This representation aligns with the fraction's numerical value, emphasizing the position of the red dot on the number line and its fractional significance in relation to the unit interval.
Hence, the correct answer is Option C. 4/5
Determining the value of the red dot requires analyzing its position on the number line relative to specific landmarks and measurements provided; however, without the visual of the number line, a precise answer cannot be given.
Explanation:The value of the red dot on the number line can be determined based on its position relative to the given reference points. The various descriptions of dots' positions involve a comparison to Car X and Car Y figures, as well as precise measurements in terms of perpendicular hash marks on a graph. To ascertain the value that the red dot represents, we must closely examine its placement on the number line in comparison to these references. However, it's crucial to have a visual representation of the number line to provide an accurate value. The mentioned descriptions such as 'the third dot is about one and two-thirds perpendicular hash marks to the right of the center top perpendicular hash mark' indicate the need to understand measuring units and relative positioning on the number line.

Find g-1(x) when g(x)=3/5x-9
Answer:
[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]
Step-by-step explanation:
let y = g(x) and rearrange making x the subject
y = [tex]\frac{3}{5}[/tex] x - 9 ( add 9 to both sides )
y + 9 = [tex]\frac{3}{5}[/tex] x
Multiply both sides by 5 to clear the fraction
5y + 45 = 3x ( divide both sides by 3 )
[tex]\frac{5y+45}{3}[/tex] = x
Change y back into terms of x, thus
[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]
The inverse is g⁻¹(x) = (5/3)*(x + 9)
How to find the inverse?
for a function f(x), the inverse f⁻¹(x) is defined as:
if f(x) = y
f⁻¹(y) = x
For this case, we can write:
g(g⁻¹(x)) = x
(3/5)*g⁻¹(x) - 9 = x
(3/5)*g⁻¹(x) = x + 9
g⁻¹(x) = (5/3)*(x + 9)

The area of the given figure 156.75 sq cm.
Step-by-step explanation:
Here,
The figure is a trapezium.
In this trapezium
a = 22 cm
b = 6.5 cm
A and b are the length of two parallel sides.
Height (h) = 5.5 cm
To find the area of the figure which is consists of two trapezium
Formula
Area of the trapezium = [tex]\frac{1}{2} (a+b)h[/tex]
Now,
The area of one trapezium = [tex]\frac{1}{2} (22+6.5)X5.5[/tex] sq cm

according to a recipe, 9/20 oz, of sugar is needed to make 6 cookies. Ashley decided to use only a third of the sugar to make it healthier. how much sugar did Ashley use?
Answer:
The amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz
Step-by-step explanation:
The amount of sugar needed to make 6 cookies = (9/20) oz
So, the total amount of sugar to be used = (9/20) oz
Let us assume the sugar actually used by Ashley = M oz
Also, given:
Sugar Used = One third of SUGAR NEEDED
[tex]\implies M = (\frac{1}{3}) \times (\frac{9}{20})[/tex]
= [tex](\frac{3}{20} )[/tex] = 0.15 oz
or M = 0.15 oz
Hence, the amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz.

On subtracting both the equation
2x + y - (3x + y ) = 8-11
2x + y -3x -y = -3
-x = -3
x = 3
Substitute the value of x in the equation 1,
2x + y = 8
2(3) + y = 8
6 + y = 8
y = 8-6
y = 2
Hence, The cost of the notebook is $3 and the cost of a pack of pens is $2.

O 2/3
0 -2/3
The scale factor of the dilation is 2/3. This means that the image point is two-thirds the distance from the original point to the center of dilation.
To find the scale factor of the dilation, we can use the formula:
[tex]\[ \text{scale factor} = \frac{\text{image point}}{\text{original point}} \][/tex]
Given that the image of (6, 9) under the dilation is (4, 6), we can substitute these values into the formula:
[tex]\[ \text{scale factor} = \frac{(4, 6)}{(6, 9)} \]\[ \text{scale factor} = \left( \frac{4}{6}, \frac{6}{9} \right) \][/tex]
Simplifying the fractions:
[tex]\[ \text{scale factor} = \left( \frac{2}{3}, \frac{2}{3} \right) \][/tex]
B. The scale factor is 2/3
To determine the scale factor of the dilation, we need to compare the coordinates of the original point 6, 9 and its image 4 , 6
The formula for dilation of a point x, y by a scale factor k is:
[tex]\[(x', y') = (kx, ky)\][/tex]
Given:

Answer:
It will be 1 0/4
Step-by-step explanation:
The 4 stays the same because its the denominater.
After using some of her ribbon for a project and a bow, Jenna has 1 meter of ribbon left on the spool.
Jenna has a spool that contains 5 and 3/4 meters of ribbon. She uses 3 and 2/4 meters for a school project and 1 and 1/4 meters for a bow. To find out how much ribbon remains on the spool, we need to subtract the total amount of ribbon used from the initial amount.
First, let's simplify the fractions. 3 and 2/4 meters can be simplified to 3 and 1/2 meters because 2/4 is equivalent to 1/2.
Next, we add the lengths of ribbon used for the project and the bow together: 3 and 1/2 meters + 1 and 1/4 meters = 4 and 3/4 meters.
Finally, we subtract this amount from the total amount of ribbon Jenna had: 5 and 3/4 meters - 4 and 3/4 meters = 1 meter.
Therefore, after using ribbon for a school project and a bow, Jenna has 1 meter of ribbon left on the spool.
