Answer:

15

Step-by-step explanation:

The ratio of trucks to cars is 6x/10. And in the problem it says that there are 25 cars. So, 10x = 25, x = 5/2. Then, 6x = 15

Answer:

x = 2, y = -1

Step-by-step explanation:

We have a solution system, x = -6y - 4 and 6x - 12y = 24.

Now, since are not only asked to use the substitution method, but at the same time know the value of x, let's plug the first system into the second.

x = -6y - 4

6(-6y - 4) - 12y = 24

-36y - 24 - 12y = 24

-48y - 24 = 24

Add 24 to both sides :

-48y = 48

Divide -48 by both sides :

y = -1

Now that we have y, we can replace it into the second system again to get x.

6x - 12(-1) = 24

6x + 12 = 24

Solve for x by first getting rid of 12 from both sides :

6x = 12

Divide 6 by both sides :

x = 2

Therefore, x = 2 and y = -1

Answer:

y=-2+4

Step-by-step explanation:

we know the y intercept is four, so we can plug that into y=mx+b

so far we know y=mx+4

and the equation for finding slope is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

so let's find two points on the graph

let's make it easy on ourselves and use the points laid out for us

(0,4) and (2,0)

[tex]\frac{0-4}{2-0}[/tex]

solving that would come out to be [tex]\frac{-4}{2}[/tex]

simplified, that would be -2

now that we know the slope, we can put them into slope-intercept form

y=-2+4

Answer:

(a) [tex]Unit = \frac{1}{4}/8[/tex]

Step-by-step explanation:

Given

[tex]Time = \frac{1}{4}[/tex]

[tex]Lap = 8[/tex]

Required

Determine the time in each lap

The unit time in each lap is calculated by dividing the total time by the number of laps; i.e.;

[tex]Unit = \frac{Time}{Lap}[/tex]

Substitute values for Time and Lap

[tex]Unit = \frac{1}{4}/8[/tex]

The trigonometric function gives the ratio of different sides of a right-angle triangle. The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse.

The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,

Sin(θ) = Perpendicular/Hypotenuse

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The hypotenuse is the longest side of the triangle.

The angle of elevation is equal to,

The angle of elevation = Sin⁻¹ (4.5/11.75)

                                      = 22.5183° ≈ 23°

Hence, the angle of elevation formed by the ramp by the ground to the nearest degree is 23°.

when x = 3,

y = -1

F(x) = 3(3) - 10 = 9 - 10 = -1

Step-by-step explanation:

-8x+5 > 21

Minus 5 from both sides

-8x > 16

Then divide 8 from both sides (also I am pretty sure the sign would change because you are dividing by a negative number)

x < -2

So the answer is x is less than or equal to -2

Answer:

Identity

Step-by-step explanation:

Conditional equation, an identity, or a contradiction.

Conditional equation: Two sides are equal for some value of x.

Identity: Two sides are equal for every value of x.

Contradiction: We have 0x = number that is not 0.

4x+5x−15=9x−10−5

Lets solve

[tex]4x + 5x - 15 = 9x - 10 - 5[/tex]

[tex]9x - 15 = 9x - 15[/tex]

Equal on both sides, so identity.

Answer:

conditional equation

Step-by-step explanation:

Collecting terms on both sides, we get

−4+3x−5x−2x−4=−1−10+x=x−11

Subtracting x and adding 4 to both sides of the equation, we get

−3x=−7

This can be solved by dividing by −3 on both sides of the equation, which gives a unique solution of 73. So, this is a conditional equation.
