Answer:

54, 69, 99.

Step-by-step explanation:

Substitute the given value into the function and evaluate.

Answer:

Step-by-step explanation:

f(x) = 5x +4

f(10) = 5*10 + 4

      = 50 +4

      = 54

f(13) = 5*13 + 4

       = 65 + 4

       = 69

f(19) = 5*19 + 4

      = 95 + 4

     = 99

Answer:

x = -10

Step-by-step explanation:

-2 (x + 6) = 8

-2x + -12 = 8

+12 +12

-2x = 20

Step-by-step explanation:

NO and PQ are congruent segments (have the same length), and both have the same midpoint M.

NO ≅ PQ, given.

NM ≅ ½ NO, definition of midpoint.

PM ≅ ½ PQ, definition of midpoint.

PM ≅ ½ NO, substitution.

PM ≅ NM, substitution.

Answer:

10 water stations are needed

Step-by-step explanation:

To get the number of water- station needed, we simply divide the total length of the half marathon by the distance where we can find a water station

mathematically,

that would be 13.1 divided by 1 1/3

= 13.1 divided by 4/3

= 13.1 * 3/4 = 9.825 which is approximately 10

Answer:

x = -1

Step-by-step explanation:

distribute:

3x + 3 = -2 (x -1) -4

distribute:

3x + 3 = -2x + 2 - 4

calculate difference:

3x + 3 = -2x - 2

move variable to left and change sign

3x + 2x + 3 = -2

3x + 2x = 2 - 3

collect like terms

5x = -2 - 3

5x = -5

x = -1

Answer:

x = -1

Step-by-step explanation:

3 ( x + 1 ) = -2 ( x - 1 ) - 4

distibute

3x + 3 = -2x + 2 - 4

simplify

3x + 3 = -2x - 2

inverse operations

3x + 3 = -2x - 2

+2x        +2x

5x + 3 = -2

    -3      -3

5x = -5

/5     /5

x = -1

Answer:

[tex]\huge\boxed{Q = 110 \textdegree, \ ST = 9 \ \text{ft}}[/tex]

Step-by-step explanation:

When we reflect and transform a figure, the angle lengths nor the side lengths are touched. The side length only changes if we dilate or stretch the figure, and the angle length only changes if we stretch the figure.

Therefore, we know the information is going to be the exact same. We just have to figure out what corresponds to what from JKLM to QTSR.

If we reflect a figure across a horizontal reflection line through its center, the figure will just flip sides. M will be J, L will be K, etc.

When we translate this down, nothing changes except its position. So we can pretend these two shapes are right on top of each other for now.

When we move these right on top of each other, we can see that Angle J overlaps with Angle Q. Since they don't have any weird intersects, we know that angle J will be equal to Angle Q. Since we already know J is 110°, we know Q is also 110°.

When we move it on top, we also see that KL overlaps with ST perfectly. Since we know KL is 9, that must mean ST is also 9.

Answer:

y > 2

Step-by-step explanation:

a double negative is basically a + sign, so its y + 5> 7, and we want Y alone so we subract 5 from 7 to get Y > 2

Answer:

[tex]y < 2[/tex]

Step-by-step explanation:

[tex]\begin{aligned}y-(-5)+(-5)&< 7+(-5)\\y& <7-5\\y&< 2\\\text{or}\\y-(-5) &= y+5\\\therefore\,y+5& <7\\y+5-5 &<7-5\\y&<2\end{aligned}[/tex]

Answer:

46.08 feet.

Step-by-step explanation:

Given that, for length, [tex]l[/tex] feet, the time period, [tex]f(l)[/tex], of the pendulum is

[tex]f(l)=2\pi\sqrt{\frac{l}{32}}[/tex].

As the time period equals the time taken by the pendulum in one back and forth motion, so, actually, the given [tex]2.4\pi[/tex] seconds to swing back and forth is the time period.

Let [tex]l_0[/tex] feet be the length of the pendulum for the time period [tex]2.4\pi[/tex] seconds, so

[tex]f(l_0)=2.4\pi[/tex]

[tex]\Rightarrow 2\pi\sqrt{\frac{l_0}{32}}=2.4\pi[/tex]

[tex]\Rightarrow \sqrt{\frac{l_)}{32}}=1.2[/tex]

[tex]\Rightarrow \frac{l_0}{32}=(1.2)^2[/tex] [squaring on both the sides]

[tex]\Rightarrow l_0=1.44\times32[/tex]

[tex]\Rightarrow l_0=46.08[/tex]

Hence, the approximate length of a pendulum that takes [tex]2.4 \pi[/tex] seconds to swing back and forth is 46.08 feet.

Answer:

Step-by-step explanation:

In this problem, we will determine the volume of the small cubes

and also we will determine the volume of the cube

given that

Each cube has sides of 2 inches.

the volume of the cube is =2^3= 2*2*2= 8inch^3

also,

The large box has sides of 10 inches.

the volume of the box is= 10^3=0*10*10= 1000inch^3

Find out how many cubes will fit in the box

1000/8=125cubes

There are 125 cubes in a box

Answer:

X = 70 degrees

Step-by-step explanation:

The way to figure this out is by taking the angle of the 30 degrees and applying it to the opposite side of its self then just add it to the 80 degrees which will equal 110 and since a straight line has 180 degrees just subtract 180 by 110 and that will be the value of x because the lines are parallel and the line that goes through both lines will always have the same angle.
