Answer:
Required numbers are x = -0.5 and y =18.6
Step-by-step explanation:
Let the two numbers be x and y
Their sum is 18 i.e x+y= 18
4/7y-5x= 14
We need to find the numbers x and y
Solving both equations to find value of x and y
[tex]x+y= 18 ----(1)\\\frac{4}{7} y-5x= 14 ------(2)[/tex]
From equation 1 we can find value of x and put in equation 2 i.e
x=18-y
Putting the value of x in equation 2
[tex]\frac{4}{7}y-5(18-y)=14\\Solving:\\\\\frac{4}{7}y-90+5y=14\\\frac{4y-90*7+5*7y}{7}=14\\ \frac{4y-630+35y}{7}=14\\4y+35y-630=14*7\\39y=98+630\\y=728/39\\y=18.6[/tex]
Now finding x
[tex]x=18-y\\x=18-18.6\\x=-0.5[/tex]
So, Required numbers are x = -0.5 and y =18.6

Five times the second of three consecutive odd integers is thirteen less than three times the sum of the first and third integers. Find the largest odd number.
Answer: 15
Step-by-step explanation:
suppose; three consecutive odd integers are x; x + 2; x+ 4 (x is a odd integer)
because Five times the second of three consecutive odd integers is thirteen less than three times the sum of the first and third integers
=> 5(x + 2) = 3( x +x +4) - 13
<=> 5x + 10 = 6x + 12 - 13
<=>6x - 5x = 10 + 13 - 12
<=> x = 11
=> the largest odd number is 11 + 4 = 15
The largest of the three consecutive odd integers which could be written as a, a+2 and a + 4 is 15
Let the integers be : a, a + 2, a + 4
Creating a mathematical equation using the scenario given.
5(a + 2) = 3(a + (a + 4)) - 13
Open the bracket bracket
5a + 10 = 3(2a + 4) - 13
5a + 10 = 6a + 12 - 13
5a + 10 = 6a - 1
Collect like terms
5a - 6a = - 1 - 10
-a = - 11
a = 11
The largest integer = a + 4 ; 11 + 4 = 15
Therefore, the largest of the consecutive odd integers is 15

Write the equation of the line that passes through the points (8, -4) and (-2,5).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given the points
(8, -4) and (-2, 5)The slope between two points
[tex]m=\frac{5-\left(-4\right)}{-2-8}[/tex]
[tex]m=-\frac{9}{10}[/tex]
As the point-slope form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -9/10 and (8, -4)
[tex]y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)[/tex]
Writing the line equation in the slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so the equation in the slope-intercept form will be:
[tex]y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)[/tex]
[tex]y+4=-\frac{9}{10}\left(x-8\right)[/tex]
subtract 4 from both sides
[tex]y+4-4=-\frac{9}{10}\left(x-8\right)-4[/tex]
[tex]y=-\frac{9}{10}x+\frac{16}{5}[/tex]
Therefore, the equation in the slope-intercept form will be:
[tex]y=-\frac{9}{10}x+\frac{16}{5}[/tex]
Find f(4) if f(x)=−3x2+11x+37
Hi there!
[tex]\large\boxed{f(4) = 33}[/tex]
f(x) = -3x² + 11x + 37
Substitute in 4 for x to find f(4):
f(4) = -3(4)² + 11(4) + 37
f(4) = -3(16) + 44 + 37
f(4) = -48 + 44 + 37
f(4) = 33

Bill's Bargains sells 16 ounces of Circle O's cereal for $3.36. Debbie's Deals sells 40 ounces of Circle O's cereal for $7.60. Which store as the better deal?
Answer:
Debbie's Deals has the better deal with a price of $0.19 per ounce compared to Bill's Bargains at $0.21 per ounce.
Step-by-step explanation:
Divide $3.36 by 16 = $0.21
Divide $7.60 by 40 = $0.19
Debbie's Deals sells the Circle O's cereal for a cheaper per ounce price thus it's the better price and the better deal.

The triangles below are similar from A to B. What is the scale factor? *
5/4
3/5
2/3
4/5
Answer: The scale is 5/4
Step-by-step explanation:
To determine the scale factor, you have to locate which sides are similar to each other .
the side length with 20 is congruent to 16
15 is similar to 12 and 10 is similar to 8.
And to get from triangle A to triangle B of any side length, we need to multiply by a certain number which is the scale factor.
And to find that number we will divide the side length of any side in triangle A by the similar side to it in triangle B.
20/ 16 = 5/4
15/ 12 = 5 / 4
10 / 8 = 5/4

rationalise the denominator of (6+root3)(6-root3) over root33
Answer:
√33
Step-by-step explanation:
In the image .
The expression (6 + √3) (6 - √3) / √33 upon rationalizing the denominator gives √33.
What is Square Root?Square root of a number is the value such that upon multiplying the value by itself twice gives the original number.
The given expression is (6 + √3) (6 - √3) / √33
We have the identity,
(a + b) (a - b) = a² - b²
∴ (6 + √3) (6 - √3) / 33 = 6² - (√3)² / √33
= (36 - 3) / √33
= 33 /√33
Multiplying numerator and denominator by √33,
(6 + √3) (6 - √3) / 33 = (33 × √33) / (√33 × √33)
= 33√33 / 33
= √33
Hence upon rationalizing the denominator in the expression (6 + √3) (6 - √3) / 33 yields √33.

Identify the key components and write an inequality for each graph:
Answer:
b= (0,3)
m= 2/3
inequality= y < 2/3x+3
Step-by-step explanation:
b is the y-intercept. the way to find the y-intercept is looking where the line ends up on the y line. m is the slope. the trick to finding the slope is to choose two points and go up then go to the side where the point is. it forms a triangle. count how much it went up and how much you went to the side. then make it rise over run. the inequality works that way since y is 2/3 of x.

Answer:
Slope: -1/4, y-intercept: -2.
Step-by-step explanation:
The line intersects the y-axis at -2. This means that the y-intercept is -2. The slope is -1/4 because since the slope is rise over run, you go up one and then to the left 4 from the y-intercept. When you do this you see that from both A to B, you will end up on the same line.

My production line creates 3 different widgets. Widget A sells for $12. Widget B sells for $18. Widget C sells for $35. I made a total revenue of $1735 yesterday. I sold a total of 70 widgets. The number of C widgets sold is equal to the total number A and B sold. How many of each type of widgets did I sell?
9514 1404 393
Answer:
20 A widgets15 B widgets35 C widgetsStep-by-step explanation:
Half the widgets sold were $35 widgets, so the revenue from them was ...
(70/2)($35) = $1225
This means the remaining $1735 -1225 = $510 in revenue came from the sale of a total of 35 A and B widgets.
If we let 'b' represent the number of B widgets sold, then the revenue is ...
12(35 -b) + 18b = 510
6b +420 = 510
6b = 90
b = 15 . . . . . . . number of B widgets sold
35 -b = 20 . . . number of A widgets sold
20 A widgets, 15 B widgets, and 35 C widgets were sold.
__
Check
Total revenue was 20(12) +15(18) +35(35) = 240 +270 +1225 = 1735.
Total widgets were 20 +15 +35 = 70.
The total of A and B was 20 +15 = 35, the same as the number of C.
