The situation given that can be represented by a graph with a y-intercept of -8 is A. Hal bought $8 worth of supplies, then sold x buttons for $3 each. His profit is y dollars.
How to use the y-intercept?The y-intercept is a figure in the linear equation that shows the original number of units before the value of x either started to increase or to decrease and therefore cause a change in x.
The situation where Hal bought $8 worth of supplies would be represented by the y-intercept of -8 because the $8 that Hal bought represents his total profit before he sells anything. That total profit is -8 because Hal has spent -$8 but has not sold anything.

basic facts can help you find 10 x 20 x 30 x 40 mentally. I need to get my homework done
The result of the multiplication is 24,000.
How to multiply any number with 10?Multiplication is simply repeated addition, and it is a crucial skill to master.
What occurred if we multiply by ten? 4 * 10 equals 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + What does this add up to? It adds up to 40. Take a look at that. We have a 4 and a 0 just at end.While multiplying whole digits by ten, surely add a 0 to a end of the number to get the answer. 5 * 10 equals a 5 with a 0 just at end: 50. 3 * 10 equals 30 (a 3 with such a 0 at the end).For the given multiplication;
= 10 x 20 x 30 x 40
This could be written in the terms of 10.
= 10 x 2 x 10 x 3 x 10 x 4 x 10
Simply count the 10 and put the same number of zero after 1 and multiply remaining.
= 2 x 3 x 4 x 10000
= 24 x 10,000
Now, put the same number of zero after the number 24.
= 240,000
Therefore, the given multiplication is solved using simple mental maths.

a) Yes, by multiplying both sides by 1/8.
b) The inequality is false, thus, there is nothing to solve.
can you use the multiplication property of inequality to solve 8m>-1/10?Yes, you can.
There is a property that says that if you perform the same operation (multiplicating by 1/8 in this case) in both sides, then the truth value of the inequality does not change.
8m > -1/10
So, if we multiply both sides by 1/8, we will get:
8m/m > -1/(10*8)
m > -1/80
The inequality is solved.
can you use the division of property to solve -9/2 >3/2?There is nothing to really solve here, as you can see, the inequality says that a negative number is larger than a positive number, so the inequality is clearly false, and thus, there is nothing to solve.

The statement which is given in option (b) is correct. Further, 25 glasses can be filled out from the 2 containers of fruit juice each held 64 ounces.
Given that, 2(64)-5g = 3 and we have to conclude the best situation from the four options given which satisfy this equation.
2(64)-5g = 3 means, the result of taking out 5 times g from the product of 2 and 64 equals to 3 in the end.
So, out of the four statement given option (b) shows the current statement i.e., Daniel had 2 containers of fruit juice. Each container held 64 ounces. How many ounces did Daniel pour in each glass, g, if he had 3 ounces left when he finished pouring?
Therefore, option (b) is correct.
Let's proceed to solve this question further, we get
The number of glasses g will be simply equal to
2(64)-5g = 3
128-5g = 3
128-3 = 5g
125 = 5g
125/5 = g
25 = g

The standard form of the given equation is y = -2/5(x + 10).
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
y = -2/5x + 4
We know that the given equation is of parabola.
Thus, converting it to the standard form of parabola,
y = a(x-h)^2 + k
where (h, k) is the vertex .
Now we have,
y = -2/5x + 4
Thus, multiplying both the side the given equation by 5 we get,
5y = (-2/5x + 4)*5
Expanding the brackets we get,
5y = -2*5/5x + 4*5
Solving we get
5y = -2x + 20
Now factoring R.H.S we get,
5y = -2x + 2*10
Taking common we get,
5y = -2(x + 10)
Dividing both the side by 5 we get,
5y/5 = -2(x + 10)/5
Solving we get,
y = -2/5(x + 10)
thus is the required standard form of the given equation.
Thus, the standard form of the given equation is y = -2/5(x + 10).

The proportional relationship between the fees paid and the number of months is given by:
y = 70x.
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality, in the case of a direct relationship, as follows:
y = kx
In the case of an inverse relationship, we have that:
y = k/x.
k is the constant of proportionality for both cases.
For this problem, the time and the fees are direct proportional, that is, the fee increases as the number of months increase.
Over a 5 month period, he has paid $350 to his neighborhood homeowners association in monthly fees, hence the constant is found as follows:

write an equation for an polynomial function whose graph intercepts the horizontal axis at -7, 8, and 15
The equation of the polynomial is -
f(x) = [tex]x^{3} - 16x^{2} -41x+840[/tex].
We have a polynomial function whose graph intercepts the horizontal axis at -7, 8, and 15.
We have to identify the polynomial.
What is Polynomial ?A polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
According to the question -
x = -7, 8, 15 are the horizontal or the x - axis intercepts of the graph of the polynomial.
This means for -
x = -7
x = 8
x = 15
the polynomial (say f(x)) is equal to 0.
Therefore, x = -7 , x = 8 and x = 15 are the solutions of the polynomial f(x).
Then -
(x + 7) , (x - 8) and (x - 15) are the factors of this polynomial. Therefore -
f(x) = (x + 7)(x - 8)(x - 15)
f(x) = [tex](x^{2} -x-56)(x-15)\\[/tex]
f(x) = [tex]x^{3} - 16x^{2} -41x+840[/tex]

Answer:
yes, 4 2/5 > √19
Step-by-step explanation:
You want to know if 4 2/5 is greater than √19.
ComparisonThere are several ways you can determine the relationship between these numbers. If you have a calculator, you can simply subtract one from the other. The sign of the result will tell you which is greater:
4 2/5 -√19 ≈ 0.0411 > 0 . . . . . . 4 2/5 is larger
Even without a calculator, you can square both numbers. Squaring positive numbers does not change their order, so ...
(4 2/5)² = 19.36 . . . . . . . . . . . . 4 2/5 is larger than √19
(√19)² = 19
Your calculator can tell you the decimal value of the two numbers, so you can compare their values yourself (as opposed to using subtraction).
4 2/5 = 4.400 . . . . . . . . . . . 4 2/5 is larger than √19

A salad dressing is made by mixing lemon juice and vinegar in the ratio 4:3 Vicky makes 700 ml of the salad dressing. How much lemon juice does she use? Give your answer in millilitres (ml).
Answer:
400 ml of lemon juice
Step-by-step explanation:
We know that there are 700 ml of salad dressing, and the ratio of lemon juice to vinegar is 4:3. We know that therefore, there are 7 equal parts. To find how many ml are in one part, we divide 700 by 7, which gives us 100. Then we can multiply that answer by 4 to find how many ml of lemon juice and 3 to find how many ml of vinegar.
100 x 4 = 400
Therefore, Vicky uses 400 ml of lemon juice.
