For all values of x, f(x) = 2x-3 and g(x) = x^2 + 1 a) Find fg(x) Simplify and give your answer in the form ax^2 + b b) Find gf(x).
Answer:
fg(x) = 2x² - 1
gf(x) = 4x²-12x +10
Step-by-step explanation:
Given the functions f(x) = 2x-3 and g(x) = x^2 + 1
a) f(g(x)) = f(x²+1)
f(x²+1) = 2(x²+1) -3
f(x²+1)= 2x²+2 -3
f(x²+1) = 2x² - 1
fg(x) = 2x² - 1
Hence function fg(x) is 2x² - 1
b) gf(x) = g(2x-3)
g(2x-3) = (2x-3)² + 1
g(2x-3) = (2x-3)(2x-3) + 1
g(2x-3) = 4x²-6x-6x+9 + 1
g(2x-3) = 4x²-12x +10
gf(x) = 4x²-12x +10
sally buys 10kg of sweets.
Answer:
150%
Step-by-step explanation:
Purchase Cost= £12 for 10kg
Sales
1 bag= 200g
200g=1 bag
1 g= 1/200 bag
10000g or 10kg= 1/200 * 10000 = 50 Bags
1 Bag = 0.60
50 Bags= 0.60*50= £30
Profit= £30- £12= 18
% Profit= 18/12 *100
=150%
two consecutive numbers if the smallest is 11
Let two consecutive numbers are : x,x+1
Sum of these numbers is -11, then
x+x+1=−11
⇒2x=−11−1=−12
⇒x=−6
and other consecutive number is x+1=−6+1=−5
The answer is -6 and −5

what do you do on this i need it asap 40 + 56 ÷ p - q
Answer:
40 + 56/p - q
Step-by-step explanation:
This equation is weird. Your answer should be 40 + 56/p - q
The only thing that would change is writing "56 ÷ p" as a fraction.
Now, here's the weird part.
If you try to solve it after rewriting "56 ÷ p" as a fraction, your answer would look like this:
40p + 56 − qp
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
p
Unless you have a math-based keyboard that would write 40p + 56 − qp over p as a fraction formatted like the equation shown above (instead of having to put a bunch of dashes so it looks like a long fraction line), then I'd stick with just typing 40 + 56/p - q.

When you divide both sides of an inequality by a negative number, you need to _____ the inequality symbol.
A. flip
B. eliminate
C. raise
D. multiply
Answer:
The correct option is option;
A. Flip
Step-by-step explanation:
When both sides of an inequality is divided by a negative number, it changes the sign of both numbers while their magnitude remain the same;
Therefore, if the right hand side of the inequality is lesser than the left hand side, when the signs of the left and right hand sides of the inequality changes after a division , by a negative number, we have;
The smaller right hand side of the inequality will then have a lesser negative magnitude than the left hand side of the inequality with a higher negative value and the left hand side (with the higher negative value) becomes lesser than the right and therefore, the symbol (sign) of the inequality is flipped
Therefore, when you divide both sides of an inequality by a negative number, you need to flip the inequality symbol.
What is the value of z in the equation 2(2.5z − 58 + 43) = 176− 46? (3 points)
Answer:
32
Step-by-step explanation:
2(2.5z − 58 + 43) = 176− 46
5z - 116 + 86 = 130
5z -30 = 130
5z = 160
z = 160/5
z = 32

What value of w makes the equation 3(-4W - 5) = -7(5 + w) true?
Answer: W= 4
Step-by-step explanation:
The value of w will be 4.
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The expression is;
3(-4W - 5) = -7(5 + w)
Now, Solve the expression as;
3(-4W - 5) = -7(5 + w)
3 × -4w - 3 × 5 = -7 × 5 + (-7) × w
-12w - 15 = -35 - 7w
Add 12w both side;
-12w - 15 + 12w = -35 - 7w + 12w
- 15 = 5w - 35
Add 35 we get;
- 15 + 35 = 5w - 35 + 35
20 = 5w
5w = 20
Divide 5 both side;
w = 4
Thus, The value of w will be 4.

1. A triangle has two angles that measure 52 degrees and 31 degrees.
What is the measurement of the third angle?
Answer:
86 degrees
Step-by-step explanation:
Interior degrees of a triangle always add up to 180 degrees
What you would do is add the first two (52+31 = 84)
Subtract this number from 180 to get your remaining degrees
86 degrees
The present price of a motorcycle is
Rs. 2,25,000. If its price is depreciated per year by 8 %, after
how many years will be the price of the motorcycle be
Rs. 1,75,204.80 ? Find it.
Answer:
3.25 years
Step-by-step explanation:
The computation of the number of years is shown below:
Given that
PV = $225,000
RATE = 8%
PMT = $0
FV = $175,204.80
The formula is shown below:
= NPER(RATE;PMT;PV;FV;TYPE)
After applying the above formula, the number of years would be 3.25 years
The same would be considered

One way to divide decimal numbers is to use an equivalent expression.
Complete the statements below to explain one way to find 8.4 ÷ 2.1.
Answer:
104Step-by-step explanation:
To determine how much a decimal was multiplied, you need to find how many places the decimal moved.
In this case we can see the decimal moved once. How many times the decimal moved can be represented by the zeros in the number. So 10 = 1
100 = 2 1,000 = 3 and it keeps going.
So since the decimal moved 1 time, the answer to question one is 10
Now question 2.
Both 8.4 ÷ 2.1 and 84 ÷ 21 will give the exact same answer. It is just easier to solve. So solve which one is easier for you. I did 84 ÷ 21.
84 ÷ 21 = 4
We can verify our answer by multiplying the the divisor by the quotient
21 * 4 = 84
So 4 is the answer to question 2
Solve for X (Geometry) Need some help ASAP
Given:
The figure of a right triangle.
To find:
The measure of x.
Solution:
According to the altitude on hypotenuse theorem, the length of the altitude is the geometric mean of segments of the hypotenuse.
Let "h" be the height of the altitude and it divides the hypotenuse if two pieces of lengths "a" and "b", then
[tex]h=\sqrt{ab}[/tex]
In the given figure, 14 is the height of the altitude and it divides the hypotenuse if two pieces of lengths 24 and x. So, by using the altitude on hypotenuse theorem, we get
[tex]14=\sqrt{24x}[/tex]
Taking square on both sides.
[tex]196=24x[/tex]
[tex]\dfrac{196}{24}=x[/tex]
[tex]\dfrac{49}{6}=x[/tex]
Therefore, the value of x is [tex]\dfrac{49}{6}[/tex] units and its approximate value is 8.167 units.
