Answer:
x=-1, y=1
Step-by-step explanation:
Answer:
( -1, 1 )
Step-by-step explanation:
To solve, graph the equations and find the point of intersection.
when graphed these equations intersect at (-1, 1)
To double-check and make sure it's correct, plug in a solve.
x = -1
y = 1
y = 2(-1) + 3
1 = 2(-1) + 3
1 = -2 + 3
1 = 1
y = x + 2
1 = (-1) + 2
1 = 1

Answer:
The area is multiplied by 4
Step-by-step explanation:
The area of a circle is directly proportional to its square radius so if the radius is increased by x, the area will be increased by x ^ 2

A linear function that represents the number of hot dogs purchased at a football game is compared to a different linear function that represents the time left in the game. Describe the key features of the functions that are needed to determine if these lines intersect.
The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.

Determine the length of GH. Round to the nearest tenth.
3.9 cm
G
52
642
H
Answer:
|GH| = 5,7 cm
Step-by-step explanation:
To know |GH|, you first need to find the length of |GD|.
We can calculate |GD| by;
cosG = |GC| / |GD|
<=> |GD| = |GC| / cosG
=> |GD| = 3,9 cm/ 0,62 = 6,33 cm
We now can easily calculate |GH| with the sinus of angle D;
sinD = |GH| / |GD|
<=> |GH| = sinD.|GD|
=> |GH| = 0,899.6,33 cm = 5,694 cm => 5,7 cm

Solve the system of equations and choose the correct ordered pair. 5x+2y= 19 4x - 3y - 6 A (3,5) B. (5-3) C. (5,3) D. (3,2)
Answer:
(3,2)
Step-by-step explanation:
5x+2y= 19
4x - 3y = 6
I will use elimination
Multiply the first equation by 4
20x +8y = 76
Multiply the second equation by -5
-20x +15y = -30
Add them together to eliminate x
20x +8y = 76
-20x +15y = -30
---------------------------
23y = 46
Divide by 23
23y/23 = 46/23
y =2
Now find x
5x+2y =19
Substitute y=2
5x+2(2) =19
5x+4 = 19
Subtract 4 from each side
5x +4-4 =19-4
5x= 15
Divide by 5
5x/5 = 15/5
x=3
The solution is
(3,2)
Use the following trinomial to answer the questions. x^2-6x-27 When going through the process of determining the factors, the two factors need to : add up to ___ multiply to ___
Answer:
The factors are 3 and -9
Step-by-step explanation:
The given trinomial is [tex]x^2-6x-27[/tex].
We need to find two factors. We know that,
3(9) = 27
So,
[tex]x^2-6x-27[/tex] can be written as :
[tex]x^2+3x-9x-27[/tex] as two factors add up to get -6 and multiply to get -27.
Hence, the factors are 3 and -9.

What is an equation of the line that passes through the points (1,3) and (8,5)?
Answer:
y=2/7x+19/7
Step-by-step explanation:
Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7
Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:
y=2/7x+b
3=2/7(1)+b
3=2/7+b
21/7=2/7+b
19/7=b
Therefore, our final equation is y=2/7x+19/7
In what direction and by how many units is the graph of f(x) = 6 sin(2x + π) − 5 vertically and horizontally shifted? (1 point)
Group of answer choices
Down 5, left pi over 2
Up 5, left pi over 2
Up 5, right pi over 2
Down 5, right pi over 2
Answer:
The first option:
Down 5, left pi/2.
Step-by-step explanation:
Let's define the translations in a general way.
Horizontal shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x + N)
if N is positive, the shift is to the left.
if N is negative, the shift is to the right.
Vertical shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x) + N
If N is positive, the shift is upwards.
If N is negative, the shift is downwards.
In this case, we have the function:
f(x) = 6*Sin(2*x + π) - 5
Where the original function was something like:
h(x) = 6*sin(2*x)
Here we can already see the vertical shift is of minus 5 units, so the shift is 5 units down.
then we get:
f(x) = h(x) - 5 = 6*sin(2*x) - 5
Now we can apply a shift to the left of π/2 units, so we get:
f(x) = h( x + π/2) - 5 = 6*sin(2*(x +π/2) ) - 5
f(x) = 6*sin(2*x +π ) - 5
Then the correct option is:
Down 5, left pi over 2

Answer:
A, C
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
the ∠A is adjacent (adj) to AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle
which one of the above trig functions fits that?
sin(Ф) = BC / AC is sin(Ф)= Opp / Hyp , so choice A) works
cos(Ф) = BC / AC is not cos(Ф) = Opp / Hyp so choice B) does not work
cos(Ф) = BA / AC is cos(Ф) = Adj / Hyp so choice C) works
AC / BC is just a ratio it's not the angle , so D) doesn't work

Answer:
40 shots total.
Step-by-step explanation:
First, change the percentage to a decimal:
80% = 80/100 = 0.80
Next, divide the amount of baskets made (32) with the decimal gotten to get the total amount of shots:
32/0.80 = 40
Brandon took a total of 40 shots.
Check. Divide 32 (shots made) with the 40 (total shots in all):
32/40 = 0.8 = 80%.

−20x+24=0, which number would have to be added to "complete the square"?
Considering the equation of the parabola in vertex form, it is found that a number of -100 would have to be added to complete the square.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
[tex]y = a(x - h)^2 + k[/tex]
In which a is the leading coefficient.
In this problem, the equation is:
[tex]x^2 - 20x + 24[/tex]
Placing it in vertex form, we would have:
[tex](x - 10)^2 + 24 + c[/tex]
Applying the square of the subtraction:
[tex](x - 10)^2 = x^2 - 20x + 100[/tex]
Hence, a number of -100 would have to be added to complete the square.

How much lace edging is needed to go around a circular tablecloth with a diameter of 6 ft?
Answer:
A= 28.27 ft²
Step-by-step explanation:
if its trying to find area for a circle then we use the formula A=πr²
A=π(3)²
A= 28.27 ft²
Answer:
the answer is 18.85ft
Step-by-step explanation:
the question is asking you to find the circumfrance (the outside of the circle) so the formula you would use is:
C = 2πr
input the values you have into the formula
C= 2 x π x 3
(the radius is the distance between the very centre of the circle to the outside. it gives you the diameter which is the distance all the way across the circle so just half the diameter, which gives you a radius of 3)
put that into your calculator and youll get the answer
C= 18.8495559215
(i rounded the answer to two decimal places = 18.85ft)
