Answer:
zero of the function occurs at x = -6
Step-by-step explanation:
Given f(x) = -4(x+3)+6(x+4)
Since the question is incomplete, we can as well find the zero of the given function. The zero exists when f(x) = 0
Hence;
-4(x+3)+6(x+4) = 0
Expand
-4x - 12 + 6x + 24 = 0
Collect the like terms
-4x + 6x - 12 +24 = 0
2x + 12 = 0
2x = -12
x = -12/2
x = -6
Hence the zero of the function occurs at x = -6

given that f(m) = m/2, find m
Answer:
let f(m) = u
multipling both sides by 2
We have 2f(m)=m
therefore m=2

What is the value of m in the diagram?
Answer:
81
Step-by-step explanation:
The angles shown are formed on a straight line
Angles formed on a straight line add up to 180
So m + m + 18 = 180
We've just created an equation that we can use to solve for m
So we can now solve for m
m + m + 18 = 180
Combine like terms
2m + 18 = 180
Subtract 18 from both sides
2m + 18 - 18 = 180 - 18
2m = 162
Divide both sides by 2
2m/2 = 162/2
m = 81

find the missing side of the triangle.
Answer:
2×sqrt(34)
Step-by-step explanation:
Pythagorean Theorem
a^2 + b^2 = c^2
(10)^2 + (6)^2 = x^2
sqrt( 100 + 36 ) = x
x = 2×sqrt(34)
Find the area of the triangle (white)
Step-by-step explanation:
something is missing here.
it is not clear, what exactly is 27 km. only the side of the orange triangle ? or the whole distance to the 90 degree angle ?
but in both cases that is not enough. we need some information about the split ratio of the orange side and the white side. it some angles in the graphic.
otherwise I can simply keep the given sides with their lengths but freely move the line between the orange and white triangles. there are infinite many solutions.
is it meant to be an isoceles triangle (2 equal sides) ? it certainly does not look like it, but that would be the only case where the given information can lead to a solution.
under that assumption the baseline of the white triangle is also 27 km.
the first side is 9km.
the second side we get via Pythagoras :
27² = 9² + x²
729 = 81 + x²
648 = x²
x = 25.46 km
now, since this is a right-angled triangle we can (especially to calculate the area) also consider the two sides enclosing the 90 degree angle as baseline and height.
the area of a triangle is baseline×height/2
area = 9×25.46/2 = 114.55 km²
Which monomials are perfect squares? Select three options.
a
25x12
b
16x9
c
6x2
d
36x16
e
9x8
Answer:
a, d and e.
Step-by-step explanation:
A perfect square is one where the coefficient is a perfect square and the exponent is even.
So they are 25x^12, 36x^16 and 9x^8.

What is mZV?
Enter your answer in the box.
Answer:
∠ V = 58°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ WYX = 180° - (52 + 24)° = 180° - 76° = 104°
∠ VYU = ∠ WYX = 104° ( vertically opposite angles )
Then
∠ V = 180° - (104 + 18)° = 180° - 122° = 58°

To paint a wooden cube, Pinocchio needs 4 grams of paint. When it is dry, he cut the cube into 8 smaller pieces of smaller size. How much paint additional paint does Pinocchio need to paint the unpainted surfaces of the smaller cubes
Answer:
9 grams of paint
Step-by-step explanation:
6×8=48
48÷4= 12
48-12=36
36÷4=9
first multiply 6 by 8 because a cube has six faces and you cut that cube eight times
second after you cut that you will have 48 faces and for every six faces there are 4 grams of paint so you divide 48 by 4 and you get 12 this means that 12 of the faces are painted
next you subtract 12 from 48 and you get 36 this means that 36 faces are not painted
lastly you divide 36 by 4 and you will get 9 grams of paint

Solve the equation using square roots.
x2 + 10 = 9
A. 1
B. ±√1
C. no real number solutions
D. –1
Answer:
C. no real number solutions
Step-by-step explanation:
Subtract 10 from both sides.
Since the square of a number, x, equals a negative number, -1, the answer cannot be a real number because the square of a real number is always non-negative. Therefore, there is no real number solution to this equation.
Answer: B. no real number solutions
no real number solutions

A recipe requires 500 mL of milk. You will make the recipe once a month for the next 4 months. You do not use milk other than for cooking. Which container of milk should you buy? (1L=1000 mL) *
Answer:
2L
Step-by-step explanation:
Each recipe = 500 mL of milk
Number of times you make recipe per month = 1
Number of months you make recipe = 4
Total milk used for 4 months = 500 mL * 1 * 4
= 2000 mL
Recall,
1L = 1000 mL
Therefore,
2000 mL = 2L
You should buy 2L container of milk
what is the equation of the axis of symmetry do the quadratic function f(x) = -(x+4) (x-1)
9514 1404 393
Answer:
x = -3/2
Step-by-step explanation:
The zeros of the function are the values of x that make the factors zero:
x = -4, x = 1
The axis of symmetry is the vertical line halfway between these zeros.
x = (-4 +1)/2 = -3/2
The equation of the axis of symmetry is x = -3/2.

Total mass = 8 kg
Mass of tool 1 = 4 kg
Mass of tool 2 = 2 kg
So,
Total mass = Mass of tool 1 + Mass of tool 2 + Mass of tool 3
=> 8 kg = 4 kg + 2 kg + Mass of tool 3
=> 8 kg = 6 kg + Mass of tool 3
=> 8 kg - 6 kg = Mass of tool 3
=> 2 kg = Mass of tool 3

The cost of carpeting a sqaure yard is $9.10. How much does it cost to carpet 12.5 square yards?
Answer:
113.75$
Step-by-step explanation:
I. When a square yard = 9.10
so 1 * 9.1 = 9.1
if 12.5 square yard
then 12.5 * 9.1 = 113.75$
