Answer:
x^2=8x-35
Step-by-step explanation:
1.1 Factoring x2-8x+35
The first term is, x2 its coefficient is 1 .
The middle term is, -8x its coefficient is -8 .
The last term, "the constant", is +35
Step-1 : Multiply the coefficient of the first term by the constant 1 • 35 = 35
Step-2 : Find two factors of 35 whose sum equals the coefficient of the middle term, which is -8 .
-35 + -1 = -36
-7 + -5 = -12
-5 + -7 = -12
-1 + -35 = -36
1 + 35 = 36
5 + 7 = 12
7 + 5 = 12
35 + 1 = 36

If R is the midpoint of QS, find QS. QR=2x+16 RS=5x-17
Answer:
QS = 76
Step-by-step explanation:
Given R is the midpoint of QS, it means the distance from R to each endpoint is equal, that is:
QR = RS
We are given
QR = 2x + 16
RS = 5x - 17
Equating:
2x + 16 = 5x - 17
Subtracting 5x:
2x - 5x + 16 = -17
Simplifying:
-3x +16 = -17
Subtracting 16:
-3x = - 16 -17 = -33
Dividing by -3:
x = 11
Let's find
QR = 2x + 16 = 22 + 16 = 38
The length of QS is double this value: QS = 2*38 = 76
QS = 76

1. José tiene en su bolsillo un grupo de monedas de 5 y 10 centavos, y hay once
monedas más de 5¢ que las de 10€. Si el total es un dólar.
halla la cantidad de monedas de cada tipo.
Answer:
Hay 14 monedas de 5 centavos y 3 monedas de 10 centavos.
Step-by-step explanation:
Llamemos "c" a las monedas de 5 centavos y "d" a las monedas de 10 centavos.
Hay once monedas más de 5¢ que las de 10¢. La expresión matemática para ello es:
c = d + 11 [1]
El total es 1 dolar. La expresión matemática para ello es:
0,05c + 0,10d = 1 [2]
Si reemplazamos [1] en [2],
0,05(d + 11) + 0,10d = 1
0,05d + 0,55 + 0,10d = 1
0,15d = 0,45
d = 3
Si reemplazamos d = 3 en 1,
c = d + 11 = 3 + 11 = 14

Intravenous fluid bags are filled by an automated filling machine. Assume that the fill volumes of the bags are independent, normal random variables with a standard deviation of 0.08 fluid ounces. (a)What is the standard deviation of the average fill volume of 22 bags
Answer:
0.017
Step-by-step explanation:
Given that:
Population standard deviation (σ) = 0.08
Standard deviation of the average fill volume of 22 bags :
The standard deviation of sample means = standard error ; defined as ;
SE = σ / √n
SE = 0.08 / √22
SE = 0.08 / 4.6904
SE = 0.0170560
SE = 0.017
A flowers company buys 7 shipments of roses for $6,500 each and 7 shipments of daffodils for $11,500 each.
What is the value of x?
98°
Answer:
x = 139
Step-by-step explanation:
Isosceles triangle.
Let the equal angles = y
y + y + 98 = 180 {Sum of all the angles of triangles}
2y + 98 = 180
2y = 180 - 98
2y = 82
y = 82/2
y = 41
x = 41 + 98 { exterior angles equals the sum of interior opposite angles}
x = 139

Calculate the dot product of x = (1, −2, 0, 4) is in double-struck R4 and y = (1, 2, 3, 4) is in double-struck R4.
Answer:
the dot product is 13
Step-by-step explanation:
The computation of the dot product is shown below:
Given that
x = (1, −2, 0, 4)
y = (1, 2, 3, 4)
Based on the above information
The dot product is
= (1) (1) + (-2) (2) + (0) (3) + (4) (4)
= 1 - 4 + 0 + 16
= 13
Hence, the dot product is 13
We simply multiplied each of them so that the correct value could come
Find the values of x and y.
Answer: y = 129, x = 51
Step-by-step explanation:
angles 129 and y are corresponding, so they are equal to each other
y and x are supplementary
so, y + x = 180
x = 180 - y = 180 - 129 = 51
Answer:
I belive y has to be at least 133 because it's just a little bit longer than the 229 one.
And x is most likely to be 125 because if you line up 129 with x, x is should be a little smaller so x should be 125

Last year at a certain high school, 12 students sought the nomination for president of the student body. In how many ways could the voters (student body) rank their first 5 choices
Answer:
95,040 ways
Step-by-step explanation:
The first position has 12 choices
The second has 11 choices (since first is filled)
The third has 10 choices
The fourth has 9 choices
The fifth has 8 choices
So the number of ways they can make the ranking will be;
12 * 11 * 10 * 9 * 8 = 95,040 ways
The number of ways could the voters (student body) rank their first 5 choices is 792 ways.
Calculation of the number of ways:Since Last year at a certain high school, 12 students sought the nomination for president of the student body.
So, here
we use the combination here
[tex]= 12!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\times 7!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\div 5\times 4\times 3\times 2[/tex]
= 792 ways
Therefore, The number of ways could the voters (student body) rank their first 5 choices is 792 ways.

a(b + c) = a x b + a x c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
Also This property is known by distributive law and applies to subtraction also.
