The functions g and h are given by g(x) = x + 1 and h(x) = x²
Find the values of x for which hg(x) = 3x² + x - 5
Answer:
x = - [tex]\frac{3}{2}[/tex] , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]
x - 2 = 0 ⇒ x = 2

Which point is best represented by the ordered pair (2, -5.5)?
A point W
b point V
c point S
d point R
Answer:
B
Step-by-step explanation:
Answer:
The answer is A, Point W.
This is because (2, -5.5) is equal to (x, y). So, x would be 2, while point y will be -5.5. Point W represents this because it goes to 2 on the x axis, and down to -5.5 on the y axis.
A TV is originally priced at $350. There is a coupon for 40% off. After the 7% sales tax, what is the price you would pay for the tv
Answer: $234.5
Step-by-step explanation: when you get a 40% off that means you would pay 60% but then you have to play 7% so you have to pay 67% of 350 wich is 234.5
Answer:
$149.8
Step-by-step explanation:
40% of 350 is 140
7% of 140 is 9.8

If a vector gets multiplied by a negative number then its direction
A. remain same
B. gets reversed
C. gets half
D. gets double
Answer:
I believe it is B
Step-by-step explanation:
Answer:
B. gets reversed
Step-by-step explanation:
except that multiplying by a negative number will reverse the direction of the vector's arrow. For example, multiplying a vector by 1/2 will result in a vector half as long in the same direction, while multiplying a vector by −2 will result in a vector twice as long but pointed…
i need help telling if these are true or false
Answers:
FalseTrueFalseTrue======================================================
Explanations:
Point A is located at (0,1). It then moves to A' which is at (0,3). Note the y coordinate goes from y = 1 to y = 3, so the scale factor is 3/1 = 3 instead of 4. Therefore, the claim is false.Point A is at (-4,4). It moves to (-2,2). Each coordinate of (-4,4) is cut in half to get (-2,2). Cutting a value in half is the same as multiplying by 0.5, so point A fits the description. Let's find out if point B does as well. B is at (2,4) and it moves to B' (1,2); we can see that point B has its coordinates cut in half as well. Points C and D also work to fit the description (I'll let you check those coordinates) which means overall, quadrilateral ABCD dilates with a scale factor of 0.5 to get to quadrilateral A'B'C'D'. The answer here is "true".Point W is at the location (-1,1). Triple each coordinate to get (-3,3) which is where point W' should be located if we applied the dilation of scale factor 3. However, the diagram shows W' is not at (-3,3). It seems to be fairly close to (-2,2) if anything. We don't need to check the other points, but I recommend you do so just for practice. The answer here is "false".Because the scale factor is 0.25 = 1/4, this means "scale factor of 0.25" is the same as "scale factor of 1/4". That tells us to "multiply each coordinate by 1/4" which in turn is equivalent to "divide each coordinate by 4". Point E is at (-4,4) which moves to (-1,1) when we divide each coordinate by 4. Note how point E' is at (-1,1). So E moves in the proper way according to the instructions given to us. Points M, W and O also move in a similar fashion after we divide their coordinates by 4. The answer here is "true".f(x) = 5 – 0.2c and g(x) = 0.2(x + 5).

Which of the following is the correct expanded form for the series below?

Σ-22
»=0
O-1-2-4-8-16
1-2 + 4-8 + 16
O-2-4-8-16
0-2 + 4 - 8 + 16
Answer:
-1-2-4-8-16
Step-by-step explanation
The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.
What is an exponent in math?An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
here, we have,
given that,
the series Σ-2^n, n = 0 to 4.
now, we have to find,
the correct expanded form for the series ,
as , we get,
the value of n = 0 to 4
so, putting the value of n = 0,1,2,3,4
we get the series as,
Σ-2^n
= -2^0 + (-2)^1 + (-2)^2 + (-2)^3 + (-2)^4
= 1 -2 + 4 - 8 +16
Hence, The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.

find area of trapezoid
Answer:
150 sqaure ft
Step-by-step explanation:
okay so the formula for area of a trapezoid is
1/2 (b1 + b2) h
so base one of 15 plus two of 10 os 25 ft
25 feet divided by 2 is 12.5 so 12.5 × 12 is 150
Cassandra must share 10 1/2 kg of cookies in 3/4 kg bags. How many bags will she complete?
Show the work.
Answer:
She will complete 14 bags of cookies
Step-by-step explanation:
Here, we want to know the number of bags to be completed by the sharing
What we have to do here is to divide the total weight of the bag of cookies by what each cookie bag can take
We have this as;
10 1/2 kg divided by 3/4 kg
= 21/2 divided by 3/4
= 21/2 * 4/3 = 14 bags

Answer:
y= -5x+7
Step-by-step explanation:
since it is parallel, the gradient is the same
m=-5
y=mX+C
y=-5x + c
sub in the coordinate to get the y intercept
(2)= -5(1)+c
2+5 = C
C=7
therefore the ans is :
y= -5x + 7
