The point (-1, 3) is the turning point of the graph with equation y = x2 + ax + b,
where a and b are integers.
Find the values of a and b.
Answers
Answer:
a = 2
b = 4
Step-by-step explanation:
Δy = 2x + a.................for turning point, Δy/Δx = 0.
Δx
0 = 2x + a
x = -a/2.........from ( -1, 3), x = -1...............so,
-1 = -a/2.................a = 2.
y = x^2 + ax + b.
y = 3 , a = 2.................substitute.
3 = (-1)^2 + 2(-1) + b
3 = 1 -2 + b
b = 4
Answer:
The turning point of a parabola is the vertex
Vertex form of a quadratic equation: [tex]\sf y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex and a is the coefficient of the variable x²)
Given:
[tex]\sf y=x^2+ax+b[/tex]vertex = (-1, 3)Therefore, a = 1
Substituting a = 1 and the given vertex into the equation:
[tex]\sf \implies y=1(x-(-1))^2+3[/tex]
[tex]\sf \implies y=(x+1)^2+3[/tex]
[tex]\sf \implies y=x^2+2x+1+3[/tex]
[tex]\sf \implies y=x^2+2x+4[/tex]
Therefore, a = 2 and b = 4

Answer:
[tex]\boxed{\sf{8x+11b+6}}[/tex]Step-by-step explanation:
To solve this problem, you have to combine like terms of x and b from one side of the equation.
4x+3(2x+5b)-4b-2x+6Combine like terms.
3(2x+5b)+4x-2x-4b+6
Solve.
4x-2x=2x
Rewrite the problem down.
3(2x+5b)+2x-4b+6
Expand the form.
Use a distributive property.
Distributive property:
A(B+C)=AB+AC
3(2x+5b)
Multiply.
3*2x=6x
3*5b=15b
Rewrite the problem.
6x+15b
6x+15b+2x-4b+6
Combine like terms.
6x+2x+15b-4b+6
Add the numbers from left to right.
6x+2x=8x
8x+15b-4b+6
Then, you add again.
15b-4b=11b
= 8x+11b+6
Therefore, the final answer is 8x+11b+6.I hope this helps you! Let me know if my answer is wrong or not.

(a) Fill in your height here rounded to the nearest foot: ___________________
(b) Choose a measure for angle A between 31° and 51° (whole numbers only): ____________
Answers
Based on the calculations, the height of this ravine is equal to 143.95 feet.
Given the following data:
Height of ravine = 100 feet.How to calculate the length of rope.First of all, we would assign a variable to the height of the ravine, which is 100 feet tall.
Let the height of ravine be h.
Note: We would choose 46° as a measure for angle A.
From the image attached, we would determine the length of the hypotenuse by using Cosine trigonometric:
[tex]Cos A=\frac{Adj}{Hyp} \\\\Cos 46=\frac{100}{h} \\\\0.6947=\frac{100}{h}\\\\h=\frac{100}{0.6947}[/tex]
h = 143.95 feet.

The unit rate for blue pencils is $0.28
The unit rate for green pencils is $0.32
The green pencils are priced less per pencil
The blue pencils are priced less per pencil.
Answers
Correct Statements:
1) The unit rate for green pencils is $0.32
2) The blue pencils are priced less per pencil.
Step-by-step explanation:
UNIT RATE:Green pencils:
Given that,
4 green pencils = $1.28
Divide 4 to both sides
1 green pencil = $1.28 / 4
1 green pencil = $0.32
Blue pencils:
Given that,
24 blue pencils = $5.52
Divide 24 to both sides
1 blue pencil = $5.52 / 24
1 blue pencil = $0.23
Blue pencil is priced less per pencil when compared to green pencil.

Dakota says, “I think you made a mistake.”
Determine the correct value for x.

Answers
Answer:
The correct answer is -30
Step-by-step explanation:
4(x+32)=8 basically you multiply 4 times the numbers that are in the parentesis which that will equals to 4x+128 because 4x1= 4x and 4x32 = 128. then you subtract 128 from 8 which equals to -120. you divide -120 by 4 which equals to -30.

What is the area of triangle rst? 6 square units 9 square units 12 square units 18 square units
Answers
The area of the considered triangle RST is given by: Option A: 9 sq. units.
How to find the area of a triangle?If we have:
Length of its base = b unitsIts height = h units long,Then we get:
Area of a triangle = [tex]\dfrac{b \times h}{2} \: \rm unit^2[/tex]
The missing image is attached below.
If we take the base of the triangle as RS, then as the line UT is perpendicular to RS (as RS is parallel to x axis and UT is parallel to y axis) and touching from the base line RS to T, thus, it can be taken as height.
Thus, we have:
Area of RST = half of length of RS (base) times length of UT (height)
As visible from image, we have:
Length of RS = 6 blocks of unit length = 6 units
Similarly, length of UT = 3 units
Thus, we get:
Area of RST = [tex]\dfrac{6 \times 3}{2} = 9 \: \rm unit^2[/tex]
Thus, the area of the considered triangle RST is given by: Option A: 9 sq. units.

Trigonometry, how would I find the area of this triangle?
Answers
Answer:
Step-by-step explanation:
Area of triangle = 1/2 * base * height
Use the side of length 5.6cm as base, the height will be a perpendicular line from the base to the tip of the triangle.
From the right-angle triangle formed by the height and the side of length 3.9cm,
sin(56°45') = height / 3.9
height = 3.9*sin(56°45')
Substituting back into the area equation:
Area = 1/2*5.6*3.9*sin(56°45')
= 9.0cm^2
= 9cm^2
Use sine rule for Area
[tex]\\ \rm\rightarrowtail Area=\dfrac{1}{2}absinC[/tex]

Which of the following shows the correct first step to solve x^2 - 16x = -21 by completing the square?
A)x^2 - 16x + 64 = -21
B) x^2 - 16x + 64 = -21 + 64

Answers
Answer:
B) [tex]x^{2} -16x+64=-21+64[/tex]
Step-by-step explanation:
The first step to completing the square is by dividing "b" by 2, squaring that number, and adding it on both sides. In this case, 16/2 = 8 and 8 squared = 64. In answer choice B, this is correctly added to both sides of the equation.
