Answer:
y=-x2 - 8x – 18 is shown by graph D.
y=x2 - 4x + 7 is shown by graph A.
y=X+5 is shown by graph C.
y=-3x - 6 is shown by graph B.
Step-by-step explanation:
In y=-x2 - 8x – 18, the coefficient of x2 is less than 0.So the graph only has a maximum value.Thefore , the graph is point upward.
In y=x2 - 4x + 7, coefficient of x2 is greater than 0.
So the graph has a minimum point and is pointed downward.
for y =x + 5, the gradient is positive.so it is graph C.There is another way to find out too but this is quicker for now.
for y = -3x - 6, the gradient is negative ,-3.So it is the graph B.

Find the missing number in the following fraction calculation
/7 ÷10 =3/35
x=6
Step-by-step explanation:
x ÷ 7 ÷10 = 3/35
(Use trial & error - since I knew x<7)
6/7 ÷ 10 = 3/35
Or
3/35 x 10
(then, simplify it to 6/7 or ÷ that by 1/7 to get 6)

A pyramid has a square base that has an area of 144 square feet. If the slant height of each triangular face is 10 in, what is the total surface area of the pyramid?
Answer:
Total Surface Area
= 384 sq ft
Step-by-step explanation:
To find Total Surface Area, add up the areas of all the sides of the shape. A square based pyramid has five sides, a square bottom and four triangular sides. Luckily all four sides are the same, so just one calculation for these.
Area of square base is given.
A = 144 sq ft
Since the base is a square the length of the side of the square is 12, because 12×12 is 144.
The side of the square base is the base of the triangular side.
Area of a triangle:
A = 1/2•b•h
A = 1/2(12)(10)
A = 60
The area of one triangular face is 60. There are four of these.
A = 4(60)
A = 240
This is the area of all the triangular faces.
Add them all up.
A (TOTAL)
= 144+240
= 384 sq ft
A cuboid with a volume of 374cm^3 has dimensions 2cm,(x+3)cm and (x+9)cm
Please help me get the full 7 marks
Answer:
x² + 12x - 160 = 0
x = 8 or x = -20
The dimensions are 2 cm, 11 cm, 17 cm.
Step-by-step explanation:
The volume of the cuboid is the product of the three dimensions.
volume = 2(x + 3)(x + 9)
volume = 2(x² + 12x + 27)
volume = 2x² + 24x + 54
We are told the volume equals 374 cm³.
2x² + 24x + 54 = 374
2x² + 24x - 320 = 0
x² + 12x - 160 = 0
(x - 8)(x + 20) = 0
x - 8 = 0 or x + 20 = 0
x = 8 or x = -20
We do not use x = -20 because it would cause two dimensions to be negative which cannot be.
x = 8
x + 3 = 8 + 3 = 11
x + 9 = 8 + 9 = 17
The dimensions are 2 cm, 11 cm, 17 cm.

At the Madison Ski Resort, it snowed 5 feet yesterday and 2/3 of a foot today. How much more did it snow yesterday than today?
Write your answer as a fraction or as a whole or mixed number.
Answer:
4 1/3
Step-by-step explanation:
this is just a subtraction problem. What you know is that it snowed 5ft yesterday and 2/3ft today. So that means that the amount of more snow yesterday can be calculated with 5 - 2/3ft (this will show how much more snow there was yesterday). The result of this expression would be 4 1/3.

Solve the equation by factoring. z2 – 6z – 27 = 0
z = –3 or z = 9
z = –3 or z = –9
z = 3 or z = –9
z = 3 or z = 9
Answer:
The value of z = -3 or z = 9
Step-by-step explanation:
Given equation => z² – 6z – 27 = 0
=> z² - 9z + 3z - 27 = 0
=> z(z -9 ) +3 (z - 9 ) = 0
=> (z + 3) (z - 9)
=> z = -3 or z = 9

What is the value of the expression 3(x+19)-25/5 if x=15
Hey there!
3(x + 19) - 25/5
= 3(15 + 19) - 25/5
= 3(15) + 3(19) - 25/5
= 45 + 57 - 25/5
= 45 + 57 - 5
= 102 - 5
= 97
OR
3(x + 19) - 25/5
= 3(15 + 19) - 25/5
= 3(34) - 25/5
= 102 - 25/5
= 102 - 5
= 97
97 = 97 ☑️
Therefore, your answer is: 97

Answer:
Value of expression = 97Step-by-step explanation:
In the question we have given an expression that is 3 ( x + 19 ) - 25/5 and value of x is equal to 15 .
And we are asked to find the value expression when value of x is 15 .
Solution : -
[tex] \longmapsto \: 3( x+ 19) - \cancel{\frac{25}{5} }[/tex]
Step 1 : Substituting value of x in given expression and cancelling 25 by 5 :
[tex] \longmapsto \: 3(15 + 19) - 5[/tex]
Step 2 : Solving parenthesis by adding 15 and 19 :
[tex] \longmapsto \: 3(34) - 5[/tex]
Step 3 : By multiplying 3 with 34, we get :
[tex] \longmapsto \: 102 - 5[/tex]
Step 4 : Subtracting 5 from 102 :
[tex] \longmapsto \: \red{ \boxed{ \frak{97}}}[/tex]
