Answer:
-40x³ + 44x² - 66x - 36
Step-by-step explanation:
f(x) = 10x + 4
g(x) = -4x² + 6x – 9
Therefore:
f(x) · g(x) = (10x + 4) · (-4x² + 6x - 9) = -40x³ + 44x² - 66x - 36

Answer:
Step-by-step explanation:
4 + (-7) = -3
First mark the the first number (4) in the number line. Then check the second number. Here it is (-7). As it is negative, we have to move to left hand side in the number line - 7 jump towards left. The final number where the jump ends will give the answer.

A. x ≥ 6
B. x ≤ 6
C x ≤ -5
Answer:
A and i'm pretty sure
Step-by-step explanation:
:D
Answer:
I think it's B.
Step-by-step explanation:
-5x + 1 ≥ -29
-5x + 1 - 1 ≥ -29 - 1
-5x ≥ -30
-5x / -5 ≥ -30 / -5
x ≥ 6
You flip the inequality sign because you divided both sides by a negative number.
x ≤ 6

Put Y=x^2+10x+18 in vertex form
Answer:(-5,-7)
Step-by-step explanation:
Rewrite in Vertex form and use this form to find the vertex (h,k)
Answer:
y = (x + 5)² - 7
Step-by-step explanation:
Given
y = x² + 10x + 18
To obtain vertex form use the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² + 10x
y = x² + 2(5)x + 25 - 25 + 18
= (x + 5)² - 7 ← in vertex form
A game spinner is divided into 5 congruent sections and labeled, as shown below.
The arrow will be spun 100 times. Which of the following is most likely the number of times the arrow will stop on the section labeled “lose a turn”?
Answer:
G. 20
Step-by-step explanation:
The spinner has a total of 5 equally sized sections. This means that each possible outcome has an equal probability of 1/5 (0.20 in decimal form) that the spinner lands on it. Therefore, to calculate the number of times that the spinner would most likely land on "lose a turn", we need to multiply the probability that we just mentioned by the number of times the spinner will be spun...
0.20 * 100 = 20 times
Finally, we can see that the spinner will most likely land on "lose a turn" 20 times in 100 spins.
Answer:
20
Step-by-step explanation:
A milkman pays tk.6.40 per liter of milk.He adds water and sells the mixture at tk.8 per liter.By doing this,he makes 37.5% profit.Find the proportion of water to milk received by the customers?
Answer:
1 : 10
Step-by-step explanation:
Let :
Water = x
Milk = y
Purchase = 6.4 * y = 6.4y
Sales = 8(x + y)
Profit accrued = 37.5%
Sales = profit made from sales
8(x + y) = 6.4x * (100%+37.5%)
8(x + y) = 6.4x * 1.375
8x + 8y = 8.8x
8y = 8.8x - 8x
8y = 0.8x
y/x = 8/0.8
y/x = 10 / 1
y : x = 10 : 1
If the scale factor from figure A to figure B is 3:8, find the value of X (giving brainliest and thanks to all!)
Answer:
x = 9
Step-by-step explanation:
Corresponding sides are in proportion, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{3}{8}[/tex] ( cross- multiply )
8x = 72 ( divide both sides by 8 )
x = 9

WILL MARK BRAINLIEST WHOEVER CAN HELP WITH THIS :DDD!
Answer:
8) 1/4
9) 1/4
10) 1/8
11) 3/8
Here are the correct answers :)
Answer:
P(2): 1/4
P(1): 1/4
P(4): 1/8
P(3 or 5): 3/8
Step-by-step explanation:
The areas marked 1, 2, and 3 each take up 1/4 of the box. This means that the probability that you will spin the arrow and land in any of those spaces is 1/4 each.
Areas 4 and 5 are HALF the size of areas 1, 2, and 3. This means that areas 4 and 5 are half of 1/4. Half of 1/4 is 1/8.
The word "or" means that you ADD whatever two probabilities they are asking for. In this case, you add areas 3 and 5. So, add 1/4 + 1/8 = 3/8.
(an easy way to add 1/4 to 1/8 is to change 1/4 to 2/8. Then you can add the two areas easily)
the system of equatuions 2y = 14 - 2x and y= -x+7 is graphed. what is the solution to the system of equations
Answer:
the solution is the whole line y = -x + 7
Step-by-step explanation:
both equations are identical
2y = 14 - 2x
=> y = 7 - x
which is exactly the same information as y=-x+7
so, there is no single crossing point. they are exactly covering each other. what "remains" is simply the whole line.
Please someone teach me this don't just solve it I wanna learn how to do it thank you!
Answer:
284 cubic cm
Step-by-step explanation:
Volume = length x width X height
Volume of first shape: 11 x 4 x 6 = 264 cubic cm
Volume of second shape: 5 x 2 x 2 = 20 cubic cm
Vol of 1st + vol of 2nd = 264 + 20 = 284 cubic cm
Answer:
284 cm^3.
Step-by-step explanation:
These are 2 prisms.
Their volume = length*width*height.
Volume of the large prism
= 4 * 6 * 11
= 264 cm^3
Volume of the small prism
= 2 * 2* 5
= 20 cm^3
So the volume of the whole solid = 264 + 20
= 284 cm^3.
f(x) = x2. What is g(x)?
g(x)
5
-(1,4)
f(x)
X
-5
5
-5
Answer:
B. g(x) = 4x²Step-by-step explanation:
f(x)= x²
the shape of f (x ) and g( x ) is same.
and those graphs lower point is ( 0 , 0 )
therefore,
will, g(x) = kx² (k ∈ real numbers)
the g(x) graph goin through the point ( 1 , 4 )
therefore,
4 = k × 1²
k = 4
∴ g(x) = 4x²
If y=3x and 2x−4y=3 , then x=
Answer:
x = -3/10
Step-by-step explanation:
Solve for x by substituting y = 3x into the other equation:
2x - 4y = 3
2x - 4(3x) = 3
Simplify and solve for x:
2x - 12x = 3
-10x = 3
x = -3/10
So, x = -3/10
Answer:
[tex]x=-\frac{3}{10}[/tex]
Step-by-step explanation:
2x - 4y = 3
y = 3x
2x - 4(y = 3x) = 3
2x - 4(3x = 3)
2x - 12x = 3
- 10x = 3
- 10x ÷ - 10 = 3 ÷ - 10
[tex]x=-\frac{3}{10}[/tex]
