Answer:
The equation of the axis of symmetry is x = 7
Step-by-step explanation:
Mathematically, we have the equation of the axis of symmetry as;
x = -b/2a
where a is the coefficient of x^2 = 1
b is the coefficient of x which is -14
So, the equation of the axis of symmetry will be;
x = -(-14)/2(1) = 14/2 = 7
So the equation of the axis of symmetry is x =7

One brand of horse feed is made of oats and barley. The ratio of oats to barley is 4 : 11 by mass. How many kilograms of each grain are needed to make 150 kg of feed? (Show your thinking)
Answer:
Below in bold.
Step-by-step explanation:
Fraction of oats = 4/(4+11) = 4/15
So fraction of barley = 11/15
Weight of oats in 150 kg = 150 * 4/15 = 40 kg
and there are 110 kg of barley,
There are 40 kg of oats and 44 kg of barley.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
The ratio of oats to barley is 4 : 11 by mass.
Here, The mass of oats = 4x
And, The mass of barley = 11x
Since, There are 150 kg feed.
Hence, We get;
⇒ 4x + 11x = 150
⇒ 15x = 150
⇒ x = 10
Thus, The mass of oats = 4x
= 4 × 10
= 40 kg
And, The mass of barley = 11x
= 11 × 4
= 44 kg

What’s the area of this polygon answer ASAP my teacher died
Answer:
Break it into 2 sections: 18 by 3 and 6 by 20
area = 54 + 120
= 174 (answer is A.)
Step-by-step explanation:
9514 1404 393
Answer:
A. 174
Step-by-step explanation:
Use your number sense. The area can be no larger than the rectangle that is 20 high and 9 wide. That rectangle's area is ...
A = LW = (20)(9) = 180
The only answer choice smaller than 180 is ...
A. 174 . . . . . square units
__
If you want to compute it exactly, you can make note of the size of the empty space at the upper left corner. That space is 20-18 = 2 units high and 9-6 = 3 units wide. Its area is A = LW = (3)(2) = 6 square units. When that empty space is subtracted from the overall rectangle area, the result is ...
180 square units - 6 square units = 174 square units.

Answer:
[tex]$\frac{j}{3}+5$[/tex]
Step-by-step explanation:
It is given Angela shared a cab with her 2 friends.
Total number of people = 3
Total fare = j $
Tip paid by Angela = $ 5
The total fare was equally divided by the 3 friends.
So, fare paid by angle = [tex]$\frac{j}{3}$[/tex]
Total money paid by Angela is = fare + tip

A rectangle and a triangle have the same area.
The dimensions of the rectangle are 3 cm and 10 cm. The base of the triangle is 6 cm.
What is the height of the triangle? How do you know?
Answer:
Height of the triangle = 10 cm
Step-by-step explanation:
Given:
Dimensions of rectangle = 3 cm , 10 cm
Base of triangle = 6 cm
Find:
Height of the triangle
Computation:
Given that area of rectangle is equal to area of triangle
So,
(l x b) = (1/2)(b)(h)
(3 x 10) = (1/2)(6)(h)
30 = 3(h)
h = 10
Height of the triangle = 10 cm

m∠MYX =?? degrees
° m∠ZMW =?? degrees
Answer:
<ZMW =90
<MYX = 29
Step-by-step explanation:
Remark
A Rhombus has a lot of peculiar properties. One of them is that the diagonals intersect at right angles. That means <ZMW =90 degrees.
Since the angle XMY = 90 degrees, it follows that <MXY + <MYX = 90 degrees because the third angle of the triangle = 90.
<MXY = 61 is given
So 61 + <MYX = 90 Subtract 61 from both sides.
<MYX = 90 - 61
<MYX = 29
m<MYX=29°
m<ZMW=90 diagonal bisect each other perpendicularly
Step-by-step explanation:
m<MYX+m<MXY+m<XMY=180 sum of interior angle of the triangle
here
m<XMY=90° diagonal bisect each other perpendicularly
m<MYX+61°+90°=180
m<MYX=180-151=29°

Answer:
2x - 7y = -34.
Step-by-step explanation:
As the line we want is perpendicular to y= -7/2 x + 9 it's slope will be
-1 /(-7/2) = 2/7.
Now we find the point of intersection ofn the 2 given lines:
x + y = 10
3x - 4y = -12
Multiply the first equation by -3:
-3x - 3y = -30
Now add this last equation to the second one:
-7y = -42
y = 6
Plug y = 6 into the first equation:
x + 6 = 10
x = 4.
So the point of intersection is (4, 6) and the equation we want passes through this, so using the point-slope form of straight line we have:
y - 6 = 2/7(x - 4)
7y - 42 = 2(x - 4)
7y - 42 = 2x - 8
2x - 7y = -42 + 8
2x - 7y = -34
Answer:
y=(2/7)x+(7/3)
Step-by-step explanation:
y=-7/2(x)+9
y=mx+c
Therefore, slope of line y is -7/2
Because line y perpendicular to the required line
Therefore, slope of the required line is 2/7
x+y=10 ........(1)
3x-4y = -12 ......(2)
(1) x 4:
4x+4y =40 ......(3)
(3) + (2)
4x+4y+3x-4y=28
x=4
by substituting x=4 into (1), we have
y=10-4=6
Therefore, the point that the line intersects is (4, 6)
let y=(2/7)x+c be the required equation
(4, 6):
6=(2/7)4+c
c=21/4
therefore, the required equation is y=(2/7)x+(7/3).
What does x equal to?
Answer:
x = 25°
Step-by-step explanation:
the angle adjacent to the 130 angle is 50 degrees
x = 180-(105+50)
x = 180-155
x = 25
what is the equation of a line parallel to the following line that passes through the points given. y=-4x+6 (2,-1)
Answer:
Short Answer Type:
y = -4x + 6
Therefore slope = (-4)
Given:
Point = (2,-1)
Slope = -4
Therefore: -1 = -8 + c
=> c = 7
Therefore equation: y = -4x + 7

Answer:
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags
Step-by-step explanation:
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
She need 3 pounds of Chocolate chip cookies and Walnuts
Let us represent
Number of bags of chocolate chip cookies = x
Number of bags of walnuts = y
She need 3 pounds of Chocolate chip cookies and Walnuts
Hence,
We have to convert oz (ounces) to pounds
For chocolate chip cookies
1 oz = 0.0625 pound
12 oz = x
Cross Multiply
x = 12 × 0.0625 pound
x = 0.75pound
For Walnuts
1 oz = 0.0625 pound
4 oz = x
Cross Multiply
x = 4 × 0.0625 pound
x = 0.25pound
Hence,
0.75 pound = $3
0.25 pounds = $2
She can only spend $15
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
Hence,
0.75x + 0.25y = 3..... Equation 1
3x + 2y = 15.... Equation 2
Multiply Equation 1 by 2 and Equation 2 by 0.25
1.5x + 0.5y = 3... Equation 3
1.5x + 4y = 30.... Equation 4
Subtract Equation 3 from 4
3.5y = 27
y = 27/3.5
y = 7.7 bags
Solving for x using Equation 2
3x + 2y = 15.... Equation 2
3x + 2(7.7) = 15
3x + 15.4 = 15
3x = 0.4
x = 0.4/3
x = 0.133 bags
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags
