The addition of 2 + 4 gives = 6
The addition of 1 + 3 gives = 4
The addition of 3 + 2 gives = 5
The exploding dots diagram is shown for the same.
There are 6 twenty fives.
There are 4 fives.
There are 5 ones.
This all adds up to -
(6 × 25) + (4 × 5) + (5 × 1)
150 + 20 + 5

Step-by-step explanation:
Systems of Equations:In a systems of equations we have to set up two equations which relate to each other and in this case we're setting up two linear equations, so let's take a look at the question.
Let's first make an equation from: "A monster pizza, m, has 7 fewer slices than twice the number on a large pizza, l" That means if we subtracted twice the large pizza from monster pizza, we would get 7 slices. [tex]2l-m=7[/tex] and if we multiply by -1 on both sides: [tex]m-2l=-7[/tex]
Now let's use the second piece of information given: "the difference between the number of slices on a monster pizza and the number of slices on a large pizza is 4 slices" this means if we take away 4 slices from the monster pizza we get the same amount of slices on a large pizza: [tex]m-4=l[/tex] and rearranging we get: [tex]m-l=4[/tex] making A the correct option

The function f(x)=x√ is horizontally stretched by a factor of 2 to form function g(x). What is the equation of g(x)? Enter your answer in the box. g(x) =
Answers
The equation of g(x) is g(x) = 2*x^(1/2)
Explanation:
The original function f(x) is defined as f(x) = x^(1/2) which is the square root of x. When the function is stretched horizontally by a factor of 2, the x term becomes 2x. So the new function g(x) is defined as g(x) = 2*x^(1/2)

Answers
Answer:
Y- intercept is (0,-5), not (0,5), but everything is right! Nice job
Step-by-step explanation:
Finding slope and Y-intercept
Slope being (y2-y1)/(x2-x1) of any two points
I'll do (6,7) and (9,13), so
(13-7)/(9-6) = 6/3 = 2.
Slope = 3
For Y-Intercept
That's where X = 0. On this graph, X = 0, where Y= -5, making the Y-intercept -5
Slope intercept form is y = mx + b
Plugging everything together, we get K(X) = 3x - 5

If the line segment joining the points A (x1, y1) and B(x2, y2) is divided by a point P in the ratio 1 : k internally, then the coordinates of the point P are P[(1x₂ + kx₁)/(1 + k)], [(1y₂ + ky₁)/(1 + k)].
How to determine the coordinates of point P?In this scenario, we would use line ratio to determine the coordinates of the point P on the directed line segment that partitions the segment into a ratio of 1 to k.
In Mathematics, line ratio can be used to determine the coordinates of the point P and this is modeled by this mathematical expression:
P(x, y) = [(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]
Substituting the given parameters into the line ratio formula, we have the following;
P(x, y) = [(1x₂ + kx₁)/(1 + k)], [(1y₂ + ky₁)/(1 + k)]

The pie chart gives the recipe for a premium blend trail mix. What part of the premium blend is composed of raisins?
Answers
Answer:
1/7
Step-by-step explanation:
All parts are equal to one therefore raisons are just 1 out of 7 other slices on the pie chart
To determine what part of the premium trail mix is composed of raisins, refer to the given pie chart. The portion represented by 'raisins' indicates the amount of raisins in the mix. Raisins slice is 1/7, so 14.28% of premium blend is composed of raisins.
Explanation:To find out what part of the premium blend trail mix is composed of raisins, you need to look at the pie chart. The pie chart should be separated into multiple sections, with each section representing a different ingredient in the trail mix. The section labeled as raisins would represent the part of the premium blend that is composed of raisins.
For example, if the 'raisins' slice is 1/4, 25%, or 90 degrees of the pie chart, this means that 1/4, 25%, or a proportional quantity of the trail mix is composed of raisins. This is because a pie chart is a circle, and a full circle is 100% or 360 degrees - so 1/4, 25%, or 90 degrees all represent the same quantity in this context.
Remember to always check the labels and any information provided in the pie chart. It provides a visual representation of data and can help you understand the proportions of different components in a mixture.

If sample variance were to be computed by dividing SS by n, then the average value of the sample variances from all the possible random samples would consistently _____ the population variance.
a. equal
b. Impossible to determine
c. overestimate
d. underestimate
Answers
If sample variance were to be computed by dividing SS by n, then the average value of the sample variances from all the possible random samples would consistently underestimate the population variance.
The sample variance is an estimate of the population variance, and it is calculated by dividing the sum of squared deviations (SS) by the sample size minus one (n - 1).
The reason for dividing by n-1 instead of n is due to the fact that the sample variance is an estimate of the population variance and not the exact value. When computing the sample variance, we use the sample data to make an estimate of the population variance. By dividing by n-1 instead of n, we adjust for the fact that the sample is a subset of the population and introduce a small amount of bias into the estimate to correct for this lack of representation.
This correction is known as the Bessel's correction and it makes the sample variance a more accurate estimate of the population variance by adjusting for the variability inherent in sampling. As a result, when sample variance is computed using the Bessel's correction (dividing by n-1), the average value of the sample variances from all possible random samples will consistently underestimate the population variance.

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The system of equations are,
⇒ 5x + 4y = - 4
⇒ 4x + 4y = 4
Now, We can solve by using elimination method as;
The system of equations are,
⇒ 5x + 4y = - 4 .. (i)
⇒ 4x + 4y = 4
⇒ x + y = 1 .. (ii)
Multiply by 5 in (ii) and subtract from (i);

Help
Answers
Answer:
8
Step-by-step explanation:
Let's call the first of the three consecutive even integers x.
Since the integers are consecutive and even, we know that the next integer will be x+2, and the next one will be x+4.
We can use this information to set up an equation:
x + (x+2) + (x+4) = 30
Simplifying this equation, we get:
3x + 6 = 30
Subtracting 6 from both sides:
3x = 24
Dividing by 3:
x = 8
So the first of the three consecutive even integers is 8
