Find two negative odd integers such that 5 times the first plus the square of the second equals -14
The two negative odd integers such that 5 times the first plus the square of the second equals -14 are: -3 and -1.
What are negative odd integers?In a multiplication or division issue, an odd number of negatives will always result in a negative odd integer.
A negative odd integer carries a negative sign and is not exactly divisible by 2.
According to the question, an equation can be formed as follows:
[tex]5a+b^{2}=-14[/tex]
Here, a and b are the two negative odd integers.
Let a= -3 and b= -1,
[tex]5a+b^{2}=5(-3)+(-1)^{2}\\[/tex]
= -15+1
= -14
Thus, the required negative odd integers are -3 and -1.

Mrs. Hamilton shows her students this graph and asks them to determine how figure A was transformed to figure B.
On a coordinate plane, triangle A has points (negative 1, 0), (negative 2, 4), (negative 1, 4). Triangle B has points (3, 1), (3, 5), (4, 5)..
Marcus suggests that figure A was reflected over the y-axis and then translated 2 to the right and 1 up. Julianne agrees, and states that the transformations could happen in any order. Which best describes the accuracy of Julianne’s statement?
Accurate. A translation of figure A of 2 to the right and 1 up and then a reflection over the y-axis produces the image, figure B.
Accurate. A reflection over the y-axis and then a translation of 1 up and 2 to the right produces the image, figure B.
Inaccurate. A translation of 2 to the right and 1 up and then a reflection over the y-axis results in a figure that is located in the second quadrant.
Inaccurate. A reflection over the y-axis and then a translation of 1 up and 2 to the right results in a figure that is located in the second quadrant.
On a coordinate plane, triangle A has points (negative 1, 0), (negative 2, 4), (negative 1, 4). Triangle B has points (3, 1), (3, 5), (4, 5)
The best accuracy for the transformation is; Accurate. A reflection over the y-axis and then a translation of 1 up and 2 to the right produces the image, figure B.
What transformation was used on the figure?
In a translation transformation, all the points in the object are moved in a straight line in the same direction. The size, the shape and the orientation of the object remain the same.
In this question, the points on triangle A are: (-1, 0), (-2, 4) and (-1, 4).
Marcus' translation is as follows:
Reflection over the y-axis which is x → -x and the points are: (1,0), (2,4) and (1,4).2 units to the right which is x → x + 2 and as such the points are: (3, 0), (4,4) and (3,4).1 unit up which is y → y + 1 and as such, the points are (3,1), (4,5) and (3,5).The points are the same of triangle B, hence the statement is accurate. According to the order of the translations, the second statement is correct.

What is the slope in the equation y = 2x + 3
In the rhombus below, solve for x and y. (Round to the nearest tenth as needed.)
The value of x and y in the rhombus are 5 and 25 respectively.
How to find the angles of a rhombus?The sum of angles of a rhombus is 360 degrees. The opposite angles of a rhombus is equal.
Therefore,
11x = 55
x = 55 / 11
x = 5
Therefore,
5y + 5y + 55 + 55 = 360
10y + 110 = 360

A box has twice as many grapes as a basket. Once 2kg of grapes were added to the basket, it contained 0.5 kg more than the box. How many kilograms of grapes are in the basket now?
By solving a system of equations, we will see that now there are 3.5kg of grapes on the basket.
How many kilograms of grapes are in the basket now?Let's define the variables:
x = kg of grapes on the box originally.y = kg of grapes on the basket originally.We know that:
x = 2y
When we add 2kg to the basket, it has 0.5k more than the box, then:
y + 2 = x + 0.5
Then we have a system of equations:
x = 2y
y + 2 = x + 0.5
We want to solve this for y, then we can replace the first equation into the second one:
y + 2 = (x = 2y) + 0.5
y + 2 = 2y + 0.5
2 - 0.5 = 2y - y
1.5 = y
This means that, originally, there are 1.5 kg of grapes on the basket. And then we added 2kg, so now there are:

353. Why does (a + b)² result in a trinomial, but (a − b)(a + b) result in a binomial?
Answer:
In [tex]$(a+b)^{2}$[/tex] is obtained by addition therefore result is trinomial while in (a-b)(a + b) the middle terms are canceled out of each other therefore result is binomial.
Step-by-step explanation:
Explanation
Given that [tex](a+ b)^{2}$[/tex] results in a trinomial, but (a-b)(a-b) results in a binomial.An expression [tex]$(a+b)^{2}$[/tex] when multiply and simplify it is equal [tex]a^{2}+a b+a b+b^{2}=a^{2}+2 a b+b^{2}$[/tex] therefore it is trinomial. Here middle term is obtained by addition. While an expression (a + b) (a-b) when multiply and simplify it is equal to [tex]$a^{2}-a b+a b+b^{2}=a^{2}+b^{2}$[/tex]therefore it is binomial because the middle that is positive ab is canceled by negative ab.Suppose that 43% of the people who inquire about investments at a certain brokerage firm end up investing in stocks, 38% end up investing in bonds, and 51% end up investing in stocks or bonds (or both).

What is the ratio of the area of the inner square to the area of the outer square?
The area of the inner square to the area of the outer square ratio is: [tex]\frac{(a-b)^2+b^2}{a^2}[/tex]
Given a figure in which an inner square is inscribed inside the outer square.
The area of a square is the product of the two sides of the square. Also known as side square.
Firstly, we will find the side of the inner square by finding the distance between the points (0,b) and (a-b,0)
S₁=√(a-b-0)²+(b-0)²
S₁=√(a-b)²+b²
Now, we will find the area of the inner square, we get
The area of the inner square=(side)²
A₁=(S₁)²
A₁=(√(a-b)²+b²)²
A₁=(a-b)²+b²square cm.
Further, we will find the side of the outer square by finding the distance between the points (0,0) and (a,0).
S₂=√(a-0)²+0²
S₂=√a²
S₂=a
Furthermore, we will find the area of the outer square, we get
The area of the outer square=(side)²
A₂=(S₂)²
A₂=a² square cm.
Hence, the area of the inner square to the area of the outer square ratio is [tex]\frac{(a-b)^2+b^2}{a^2}[/tex].

After 1 year, $70,060 deposited in a savings account with simple interest had grown to a total of $77,136.06. What was the interest rate?
Answer:
10.1%
Step-by-step explanation:
Interest = PRT/100
Interest = 77136.06 - 70060 = 7076.06
Interest = PRT/100
7076.06 = [(70060) × R × 1] / 100
7076.06 = 70060R/100
Cross multiply
(7076.06 × 100) = 70060R
707606 = 70060R
R = 707606/70060
R = 10.1%

What are Units?The rightmost position in a number or the number one can be considered a unit in mathematics. An individual thing or person that is viewed as distinct and whole but also a component of a total or group is another definition of a unit. When discussing an item's unit price, the word "unit" is also used. It refers to the price per unit, liter, or kilogram. Unit conversion is a multi-step process that includes rounding, selecting the appropriate number of significant digits, and multiplying or dividing by a numerical factor. NIST SP 1038 describes this multi-step method in detail, along with a rounding approach for technical publications, specifications, and other uses including packaged goods in the commercial marketplace and temperature.Converting yards into inches, we get:
1 cu yard = 46656 cu inches
11 cu yard = y cu inches
Cross-multiplying, we get:
y = 11 x 46656
y = 513216 cu inches
Now, total inches would be = 513216 + 17 = 513233 cu inches

find the unknown sizes of angles
(Urgently needed please help to solve)
Answer:
x=70, y=40, z=70
Step-by-step explanation:
So whenever you have a straight line, the angle is going to be 180 degrees, and whenever you have multiple angles that make up one angle, the sum of the multiples angles is going to be the angle of the one angle.
So let's look at x. The 180 degree angle consists of 110 degrees and x, the sum of these two should add up to 180 degrees, you can set up an algebraic equation to solve for x, but you can also do some simple mental math to see that x=70, so that 110+70=180. You do the same thing for the other angles
For y, you simply need to know 140+y = 180 so y=40
For z there is two methods, you can use the fact that opposite angles are congruent, or you can use the fact that the sum of the interior angles of a triangle is 180 degrees. This means that x+y+z=180 and since we know that x=70 and y=40 then 70+40=z so 110+z=180 so z=70, which is also the same as the opposite angle, you could use either method although knowing that opposite angles are congruent is much more easier. It's called the vertical angles theorem.
