Answer:
7 and 3
Step-by-step explanation:
Using the given information, one can form an equation. Let the first number be (x) and the second (y). For two equations based on the given information.
"the sum of two numbers is 10"
x + y = 10
" the sum of their squares is 58 determine"
[tex]x^2+y^2=58[/tex]
Solve for the equation for (x), then substitute the expression for (x) into the second equation. Simplify and solve to find the value of (y), and backsolve for the value of (x).
x + y =10
x = 10 -y
Substitute into the other equation:
[tex]x^2+y^2=58[/tex]
[tex](10-y)^2+y^2=58[/tex]
Simplify, remember the pattern for opening a binomial squared:
[tex](a - b)^2=a^2-2ab+b^2[/tex]
Apply this pattern here to simplify,
[tex](10-y)^2+y^2=58[/tex]
[tex]100-20y+y^2+y^2=58[/tex]
Simplify further,
[tex]100-20y+y^2+y^2=58[/tex]
[tex]2y^2-20y+100=58[/tex]
Inverse operations,
[tex]2y^2-20y+100=58[/tex]
[tex]2y^2-20y+42=0[/tex]
Factor, take out a common factor that all of the terms have. Then rewrite the quadratic trinomial as the product of two linear binomials. Remember the general pattern for factoring, add the inverse of the factors of the constant term to the variable, the sum of these factors must equal the coefficient of the linear term of the quadratic trinomial.
[tex]2y^2-20y+42=0[/tex]
[tex]2(y^2-10y+21)=0[/tex]
[tex]2(y-7)(y-3)=0[/tex]
Now use the zero product property to solve, the zero product property states that any number times zero equals zero.
[tex]2(y-7)(y-3)=0[/tex]
[tex]y = 7, y = 3[/tex]
Since the sum of (7) and (3) is (10), one has found the values of (y), it can be either (7) or (3), it doesn't matter which equals which.
1. The sum of x and 10 is -1. Find x.

Solve the system of equations below by graphing both equations with a pencil
and paper. What is the solution?
y = x+1
y=-3x+4
Answer:
Option (C)
Step-by-step explanation:
System of the equations have been given as,
[tex]y=x+1[/tex] --------(1)
[tex]y=-\frac{1}{2}x+4[/tex] -------(2)
Substitute the value of y from equation (1) to equation (2),
[tex]x+1=-\frac{1}{2}x+4[/tex]
[tex]x+1=-\frac{1}{2}x+4[/tex]
[tex]x+\frac{1}{2}x=4-1[/tex]
[tex]\frac{3}{2}x=3[/tex]
[tex]x=2[/tex]
Substitute the value of 'x' in equation (1),
[tex]y=2+1[/tex]
[tex]y=3[/tex]
By using a graphing utility, graph of the equations that will intersect each other at a point (2, 3).
Therefore, solution of the system of equations will be [tex](2,3)[/tex].

What are the root(s) of the quadratic equation whose related function is graphed below?
Answer:
0 and 4
Step-by-step explanation:
roots are where the graph intersects at x axis
The roots of the quadratic equation whose related function is graphed are 0 and 4, the correct option is C.
What is the quadratic equation?A quadratic equation is a second-order equation written as ax2 + bx + c = 0 where a, b, and c are coefficients of real numbers and a ≠ 0.
If b2 – 4ac > 0 roots are real and different. As the discriminant is >0 then the square root of it will not be imaginary. It has two cases.
If b2 – 4ac is a perfect square then roots are rational. As the discriminant is a perfect square, so we will have an integer as a square root of the discriminant. Hence, the roots are rational numbers.
The shape of the graph is a downward parabola on the positive x-axis therefore the roots of the graph are positive.
From the given option the roots of the equation are 0 and 4 both are positive.
Hence, the roots of the quadratic equation whose related function is graphed are 0 and 4.

Darryl has written 60 percent, or 12 pages, of his history report. Darryl wants to figure out how many total pages he needs to write. Darryl’s work is shown below.
Step 1: Write 60 percent as a ratio. StartFraction part Over whole EndFraction = StartFraction 60 Over 100 EndFraction
Answer:
total pages = 20
Step-by-step explanation:
60% of an unknown number is 12
Let the unknown number (total pages) be x.
60/100 of x = 12
60/100 * x = 12
3/5 x = 12
x = 12 * 5/3
x = 20

Answer:
y =(x-9)^2 +2
Step-by-step explanation:
The vertex form of a quadratic is
y = a(x-h)^2 +k where (h,k) is the vertex and a is a constant
y = a(x-9)^2 +2
We can choose a if not given another point so I choose a = 1
y =(x-9)^2 +2

4000 people were randomly selected for a survey. It was found that 50% read the newspapers in Nepali language, 45% read the newspapers in English language and 25% read neither of them. How many families read the both? Also, find the number of families who read exactly one kind of these papers. +
Answer:
1) 800 (read the both) 2) 2200 (read exactly one)
Step-by-step explanation:
Find the people (families) who read neither of them
4000/100*25= 1000
It means that the rest 4000-1000= 3000 families read the newspapers at least in one language from the pointed languages. 4000/1oo*50= 2000 - readers in Nepali
4000/100*45= 40*45=1800 - readers in English.
2000+1800= 3800- the special amount, that consists of 1) only Nepali readers
2) only English readers 3) the readers in two languages (but the were counted twice, because we considered them in the group of Nepali readers and group of English readers)
The real quantity of only Nepali readers, only English readers and both language readers is 3000.
S0 3800-3000= 800 people - read in two languages
3000-800=2200 families read exactly one kind of these papers
rationalise the denominator of 2sq3+3sq2/4sq3+sq2
Answer:
[tex]\frac{9+5\sqrt6}{23}[/tex]
Step-by-step explanation:
We can rewrite the fraction as
[tex]\frac{2\sqrt{3}+3\sqrt{2}}{4\sqrt{3}+\sqrt{2}}[/tex]
In order to rationalize the denominator of such a complex fraction, we must multiply the fraction by the conjugate of the denominator. In this case, the conjugate of the denominator would be [tex]4\sqrt{3}-\sqrt{2}[/tex]. Multiplying both sides of the fraction by the conjugate of the denominator would result in the fraction:

The Angelica's monthly loan payments for this loan after she graduates in 4 year is $408.
What is simple interest?Simple interest is a quick and easy method of calculating the interest charge on a loan.
What is the formula for calculating the simple interest?The formula for calculating the simple interest is
[tex]Simple\ interest = \frac{P\times R\times T}{100}[/tex]
Where,
P is the principal amount
R is the interest rate
And, T is the time in years
According to the given question.
Principal amount, P = $18,000
Interest rate, R = 6.8%
Time, T = 4 years
Therefore,
The monthly loan payments, we calculate the simple interest for monthly
= [tex]\frac{18000 \times 6.8\times 4}{100 \times 12}[/tex] = $408
Hence, the Angelica's monthly loan payments for this loan after she graduates in 4 year is $408.

Select two choices that are true about the function f(x)=23x+14/x
Answer:
There is an asymptote at x = 0
There is an asymptote at y = 23
Step-by-step explanation:
Given the function:
(23x+14)/x
Vertical asymptote is gotten by equating the denominator to zero
Since the denominator is x, hence the vertical asymptote is at x = 0. This shows that there is an asymptote at x = 0
Also for the horizontal asymptote, we will take the ratio of the coefficient of the variables in the numerator and denominator
Coefficient of x at the numerator = 23
Coefficient of x at the denominator = 1
Ratio = 23/1 = 23
This means that there is an asymptote at y = 23
What is the percent increase each year for the investment?
Answer:
11.5%.
Step-by-step explanation:
Looking at the base of the exponent, it can be seen that it is 1.115. 1.00 is equal to 100% of the investment value each year. There is an additional 0.115, which is equivalent to 11.5%, which represents the increase in the investment value each year.
Therefore, the percent increase each year for the investment is 11.5%.
