The equation by completing the square (x + 7)^2 = 16 or (x - 7)^2 = 16. The solutions to the equation are; A. x = -4 ± 3
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Consider the equation: x^2=-8x-7
1) Rewrite the equation by completing the square. Write it as (x+c)^2=d or (x-c)^2=d
Here the equation: x^2=-8x-7
x^2 + 8x + 7 = 0
Where a = 2, b = 8 , c = 7
(x+c)^2 = d or (x + 7)^2 = 16
(x-c)^2=d or (x - 7)^2 = 16
2) The solutions to the equation are;
A. x = -4 ± 3

The coordinates of the vertexes of a triangle are A(3,3) B(6,6) C(9,3). What will be the new coordinates after a dilation
with a scale factor of 3 if you use the origin as the center of dilation?
0)
A)
A (9,9) B'(18,18) C'(27,9)
B)
A'(0,0) B'(3,3) C (6,0)
A'(1,1) B'(2.2) C'(3,1)
D)
A'(6,6) B'(9.9) C'(12,6)
Answer:
A
Step-by-step explanation:
Dilation by 3 from origin causes each point to be multiplied by 3.
(3,3) * 3 = (9, 9)
(6, 6) * 3 = (18, 18)
(9, 3) * 3 = (27, 9)
which is A

Answer:
27.50
Step-by-step explanation:
Since it is 16.50 each and they bought 5 packets total an easy way to solve this problem would be that you multiply 16.50 × 5 which will give you how much the total cost of the candy would be:
16.50 × 5 = 82.50
Since that is the total amount you would then divide 82.50 by 3 since Mary and her friends all split the cost three ways (since there are three of them):
82.50 ÷ 3 = 27.50
Which will give you your answer.

which table represents a linear function?
Answer:
Bottom right table
Step-by-step explanation:
A table will show a linear relationship when there is a common difference. To determine this, we first ensure that the x values are increasing at the same value and then find the difference of consecutive y values.
Top left table
11-7=3
12-11=1
13-12=1
Because the differences between the y values are not all the same, this table does not represent a linear function.
Top right table
9-7=2
12-9=3
15-12=3
Again, there is no common difference, so this table does not represent a linear function.
Bottom left table
The x values are different now but they still increase by the same increment each time, so we continue subtracting the y values normally.
9-7=2
12-9=3
15-12=3
This table does not represent a linear function.
Bottom right table
9-7=2
11-9=2
13-11=2
Because there is a common difference, this table represents a linear function.

Find tan(B) in the triangle.
Answer:
3/4
Step-by-step explanation:
The value of tangent ratio [tex]tan \beta[/tex] in the triangle is [tex]\frac{3}{4}[/tex].
What is trigonometric ratio?Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.
Review all six trigonometric ratios: sine, cosine, tangent, cotangent, secant, & cosecant.
Tangent ratioTangent ratio is yet another trigonometric ratio for right-angled triangles. Tangent ratio is the ratio of opposite side to adjacent side of a right triangle.
According to the triangle ABC
<C = [tex]90^{0}[/tex], <B = [tex]\beta[/tex], AB = 5, BC = 4, AC = 3
Tangent ratio is the ratio of opposite side to adjacent side of a right triangle.
Tangent ratio is one of the trigonometric ratios.
[tex]tan \beta=\frac{AC}{BC} = \frac{3}{4}[/tex]
Hence,
The value of [tex]tan \beta[/tex] in the triangle is [tex]\frac{3}{4}[/tex].

Alex's car depreciates in value by 18% per year.
Alex bought his car for £34000.
Work out how much his car will be worth after 5 years ?
Answer:
£12605.15
Step-by-step explanation:
Compound interest formula
34000(1-0.18)^5
The worth car after 5 years will be £12,605.15.
What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
[tex]\rm A = P \left (1 \pm r \right ) ^{t}[/tex]
Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.
Alex's vehicle deteriorates in esteem by 18% each year. Alex purchased his vehicle for £34000. Then the worth car after 5 years will be given as,
A = 34,000 (1 - 0.18)⁵
A = 34,000 x (0.82)⁵
A = 34,000 x 0.3707
A = £12,605.15
The worth car after 5 years will be £12,605.15.

Question 2 1 pts Asplaner has three sections colored green, purple, and pink. If the spinner is spun three times, how many possible outcomes are there!
Answer:
27
Step-by-step explanation:
The Counting Principle states that the number of possible outcomes is equal to the product of the number of outcomes for each event. In this case, (M)(N)(O).
There are 27 possible outcome if the spinner is spun three times.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, A spinner has three sections colored green, purple, and pink.
From the general formula of probability:
Probability = (desired outcomes)/(Total outcomes)
In our case,
the three possible outcomes of this event occurring are Green, Purple, and Purple, Green.
The desired outcomes = 3
The total outcomes = 3 x 3 x 3 = 27

Step-by-step explanation:
Problem 1
If n is the smallest of the consecutive integers, the next integer would be n+1.
Problem 2
The equation is terms of n is going to be
s = n + n + 1 + n + 2 + n+3
Problem 3
Collect like terms on the right
s = 4n + 6
Problem 4
4n + 6 = s Subtract 6 from both sides
4n = s - 6 Divide by 4
n = (s - 6)/4
Problem 5
Solve for n when s = 2174
n = (2174 - 6)/4
n = 2168 / 4
n = 542
check
n = 542
n + 1 = 543
n + 2 = 544
n + 3 = 545
