4. What value of x makes this equation true? ​

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.

Hello! answer: x = 12

Step-by-step explanation:

This is a complementary angle meaning it will add up to 90 degrees 12 + 42 = 54 3 × 12 = 36

54 + 36 = 90 therefore x = 12 HOPE THAT HELPS!

Step-by-step explanation:

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%.

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

Answer:

The area is multiplied by 4.

Step-by-step explanation:

Answer and Step-by-step explanation:

As we can see by the given figure, we can cut out 2 rectangular prisms from this shape.

This gives us an easier time to find the volume. We will be using the volume formula for rectangular prisms: Length × Width × Height

The first prism has side lengths of:

Height = 6

Length = 11

Width = 7 (from the two 2's and the one 3 added together -- 2 + 2 + 3 = 7)

Let's multiply these values together.

6 × 11 × 7 =

66 × 7 =

462 -- First volume

The second prism has side lengths:

Height: 6

Length: 9

Width: 3

Let's multiply these values together.

3 × 6 × 9 =

3 × 56 =

168 -- Second volume

Now, we add together the volumes to get the volume of the composite figure.

168 + 462 = 630

The volume of the composite figure is 630 cubic feet.

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

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)

a) the first negative number will be -1

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.

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.

Step-by-step explanation: Pythagorean theorem

Answer:

C.   a = 6

Step-by-step explanation:

Use the Pythagorean theorem

[tex]a^{2} + 8^{2} = 10^{2}[/tex]

[tex]a^{2}[/tex] + 64 = 100

[tex]a^{2}[/tex] = 36

a = 6

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:

(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

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.
