Answer:
D
Step-by-step explanation:
2x+1=3
-1 on both sides: 2x=2, then divide by two. You get x=1
For this you would use D, subtraction and division
Answer:
x = 1
D) Subtraction and Division
Step-by-step explanation:
2x + 1 = 3
(2x + 1) - 1) = (3) - 1 ←
2x = 2
(2x)/2 = (2)/2 ←
x = 1

To eliminate the y terms and solve for x in the tewest steps, by which constants should the equations be multiplied by before
adding the equations together?
First equation: 4x - 3y = 34
Second equation: 3x + 2y - 17
The first equation should be multiplied by 2 and the second equation by 3.
The first equation should be multiplied by 2 and the second equation by -3.
The first equation should be multiplied by 3 and the second equation by 4.
The first equation should be multiplied by 3 and the second equation by -4.
Answer:
First answer option:
"The first equation should be multiplied by 2 and the second equation by 3. "
Step-by-step explanation:
The first equation should be multiplied by 2 and the second equation by 3. This way the term in y in the first equation becomes "(2) (-3y) = -6y", and the term in y in the second equation becomes "(3) (2y) = 6y" so when added term by term, the term in "y" disappears.
That is represented by the first statement in your list of possible answers
Use the map shown below to find the distance between cities A and B to the nearest tenth.
Answer:
6.3
Step-by-step explanation:
√6²+2²=√40= 6.3
Answer:
Distance between A and B is approximately 6.3 units
Step-by-step explanation:
We can use the Pythagorean Theorem to solve this question. Notice that the distance in between the two points (straight segment that joins both) can be identified to the "hypotenuse of a right angle triangle shown in the attached image. Such triangle has two legs that measure 2 units one of them and 6 units the other one.
The length of the associated hypotenuse is given then by:
[tex]distance=\sqrt{2^2+6^2}\\distance=\sqrt{40} \\distance=6.32455[/tex]
So this rounded to the nearest tenth is:
6.3 units

Write an equation in point-slope form for the line through the given point with the given slope.
(–3, –7); m = -6/5
Answer:
y+7= -6/5(x+3)
Step-by-step explanation:
Point slope form for a line is given by
y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line
y - -7 = -6/5(x - -3)
y+7= -6/5(x+3)

Complete the square please.
Answer:
(x-3)^2 + (y+2)^2 = 9^2
Step-by-step explanation:
x^2 -6x+y^2+4y-68 = 0
Complete the square
x^2 -6x+y^2+4y-68+68 = 0+68
x^2 -6x+y^2+4y = 68
Find the term to add for x
-6 /2 = -3 -3^2 = 9
Find the term to add for y
4/2 =2 2^2 = 4
Add 9 and 4
x^2 -6x+9+y^2+4y+4 = 68+9+4
(x-3)^2 + (y+2)^2 = 81
(x-3)^2 + (y+2)^2 = 9^2
The standard form is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

A travel agency surveyed 1000 people to find out how many of them visited London and Paris. 310 people vistied London, 222 people visited Paris and 118 people visited both cities. How many people vistied none of these cities? A.414 B.104 C.192 D.586
Answer:
586Step-by-step explanation:
Using set notation to answer the question.
let n(U) be the total number of people surveyed = 1000
n(L) be number of people that visited London = 310
n(P) be number of people that visited Paris = 222
n(P∩L) be number of people that visited both cities = 118
n(P∪L)' be number of people that visited none of the cities = x
n(U) = n(PUL) + n(PUL)'
We willl get n(PUL) using the formula;
n(PUL) = n(P)+ n(L)-n(P∩L)
n(PUL)= 222+310-118
n(PUL)= 414
Since n(U) = n(PUL) + n(PUL)'
1000 = 414+n(PUL)'
n(PUL)' = 1000-414
n(PUL)' = 586
586 peoples visitied none of these cities?

Step-by-step explanation:
The height of a triangle is 6x and the base is (3x + 10) cm. The area of the triangle is 816 sq. cm. What are the dimensions of the base and the height of the triangle?
Answer:
Height: 48
Base: 34
Step-by-step explanation:
The formula for a triangle is 1/2(base)(height)
1/2(3x+10)(6x) = 816
18x² + 60x = 1632
18x² + 60x - 1632 = 0
Then, we use the Quadratic formula
x = (-60 ± √3600 + 117,504)/36
x =( -60 ± 348/36)
x = 288/36
x = 8
3(8) + 10
= 34
6(8) = 48
Therefore the dimensions are:
Height: 48
Base: 34
For which acute angle are the sine of the angle and cosine of the angle equal?
Answer:
∠45°
Step-by-step explanation:
When looking at a unit circle, the only acute angle (an angle between
0° and 90°) that consists of an equal sine and cosine is 45°. This is because:
[tex]sin 45 = \frac{\sqrt{2} }{2}[/tex]
[tex]cos45 = \frac{\sqrt{2} }{2}[/tex]
45° is the only acute angle that contains an equal sine and cosine.
Answer:
45 degrees
Step-by-step explanation:
Since Sin(90-x) = Cos(x), we can find that the angle at which 90-x=x is 45 degrees. This corresponds to [tex]\frac{\pi }{4}[/tex] radians

Find the value of x in the quadrilateral below.
Answer:
120
Step-by-step explanation:
The sum of the degrees in any quadrilateral is 360. So add up all of the degrees you know and subtract it from 360 to get your answer.
120 + 60 + 60 = 240
360 - 240 = 120
another way you know that's easier is the angles that are diagonal are equal to one another, so since x is diagonal to 120, it is equal to 120.

Factor: 9x^2 + 6x + 12x + 8 *
please help me
Answer & Step-by-step explanation:
9x² + 6x + 12x + 8
First, simplify the expression.
9x² + 18x + 8
Now that you have simplified the expression, you can start factoring it. First, you have 9x². You can factor into 3x and 3x because 3 times 3 is 9 and once you multiply x by x, you will get x².
(3x + )(3x + )
Now that we have this part of the factoring, we have to find the other part. We can do this by looking at our constant number. Constant meaning a number that does not have a variable beside it. So, in this case, our constant is 8. We can reduce 8 into 2 and 4 because 2 times 4 is 8.
(3x + 2)(3x + 4)
So, the factored form of 9x² + 6x + 12x + 8 is (3x + 2)(3x + 4)

O A. yis all numbers.
OB. -1 sys1
O C. y>-1
O D. {-1,1)
Answer:
B. -1 ≤ y ≤ 1
Step-by-step explanation:
The range is the vertical extent of the function. Here, it appears the function is a sine function (y=sin(x)). The least value of the function is -1; the greatest value is +1. The function can take on any value between these extremes.
An appropriate description of the range is ...
-1 ≤ y ≤ 1

Answer:
Circle
Step-by-step explanation:
The equation for a circle is in the form (x - h)² + (y - v)² = r², where (h, v) is the center of the circle and r is the radius.
A circle with its center at the origin will have an equation that looks like x² + y² = r², which is the form this equation is in.
That's how we know this equation belongs to a circle!

What is the value of x
Answer:
52°
Step-by-step explanation:
By remote interior angle theorem of a triangle:
115° = 63° + x° ( x is the vertical angle of one interior angle of the triangle)
x° = 115° - 63°
x° = 52°
x = 52
