Answer: x= -8

Step-by-step explanation: 7x=-56. The goal is to find just 1x. To do this, you need to divide both sides by 7. So 7x divided by 7 is x, and -56 divided by 7 is -8. So x= -8.

Answer:

2330.51 miles

Step-by-step explanation:

Given that the speed of the airplane = 610 mph.

The airplane leaves an airport at 9:00 P.M. with a heading of 270 degrees and at 10:00 P.M., the pilot changes the heading to 310 degrees.

So, for 1 hour the plane is heading at 270 degrees and for 3 hours, from 10:00 p.m to 1:00 a.m, the plane is heading at 310 degrees as shown in the figure.

As, distance = time x speed, so

The distance covered at 270 degrees, [tex]d_1 = 1\times610=610[/tex] miles.

The distance covered at 310 degrees, [tex]d_2 = 3\times610=1830[/tex] miles.

Total distance covered, d, is the magnitude of the sum of vectors [tex]\vec{d_1}[/tex] and [tex]\vec{d_2}[/tex] as shown in the figure.

The angle between the vectors [tex]\vec{d_1}[/tex] and [tex]\vec{d_2}[/tex], [tex]\theta=310-270=40[/tex] degree.

Magnitude of sum of the vectors \vec{d_1} and \vec{d_2},

[tex]d= \sqrt{|\vec{d_1}|^2+|\vec{d_2}|^2+2|\vec{d_1}|\;|\vec{d_2}|\cos\theta} \\\\\Rightarrow d=\sqrt{610^2+1830^2+2|\vec{d_1}|\;|\vec{d_2}|\cos\(40^{\circ})}[/tex]

[tex]\Rightarrow d=2330.51[/tex] miles

Hence, at 1:00 a.m, the airplane is at a distance of 2330.51 miles from the airport.

Answer:

-13

Step-by-step explanation:

I didn't incliDE the 3 at the first if I need to include it I will do again

Answer:

yes

Step-by-step explanation:

100 / 8 = 12.5

Answer:

yes; he brought $13, and the ticket is $12.50

Step-by-step explanation:

Since there are 8 people, and all tickets cost the same, and the total is $100, then each ticket is $100/8.

$100/8 = $12.50

Since $13 is greater than $12.50, then Noah has enough money for his ticket.

Answer:

y=-1/2x+0

Step-by-step explanation:

First, find the slope by choosing two points and counting up and over (rise over run). Then, find where the line crosses the y-axis to get the y-intercept.

For the two points, let's choose (0,0) and (-2,1). You can either count up and over to get slope, or you can use the slope formula which is y2-y1/x2-1x.

1-0/-2-0 = -1/2.

Since this line represents a negative slope, your slope is -1/2.

Now, looking at the graph, you can see that the line crosses the y-axis at 0. This is your y-intercept.

Answer:

Step-by-step explanation:

4x+4≤9x+8

move terms of x to one side, move the numbers to a different side, giving you

-4≤5x

Then, divide the 5 from both sides, giving you.

-4/5≤x

Answer:

the slope is -3, the y intercept is 5

Answer:

103

Step-by-step explanation:

a triangle has a total of 180* so 180-40-37 will give yu the missing side which is 103

Answer:

Actually the correct answer is D

Step-by-step explanation:

This question is based on the scalene triangle and orthocenter. Therefore, the correct option is D i.e. The orthocenter will be inside, on, or outside the scalene triangle, depending on whether it is acute, right, or obtuse, respectively. The number of congruent sides does not affect the location of the orthocenter.

In this question we have to choose correct appropriate option related to  relationship between a scalene triangle and the location of its orthocenter.

By the definition of scalene triangle:

A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.

Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.

Orthocenter:

The orthocenter of a triangle is the intersection of the triangle's three altitudes.

Therefore, the correct option is D i.e. The orthocenter will be inside, on, or outside the scalene triangle, depending on whether it is acute, right, or obtuse, respectively. The number of congruent sides does not affect the location of the orthocenter.

As per the given data, there are 2 different ways they can stand in line.

When we say "line up," we usually mean that the arrangement is in some sort of order or sequence.

As previously stated, if there are two students, there are two possible ways for them to line up in a sequence. If we consider the order or position they are in, the following arrangements are possible:

There are only two possible arrangements when there are two students: Zachary in front of Anthony or Anthony in front of Zachary.

Thus, they have two options for standing in line.

Answer:

[tex]x = 2[/tex] or [tex]x = -1[/tex]

Step-by-step explanation:

Given

[tex]\sqrt{x + 2}= {-x}[/tex]

Required

Find the possible values fo x

[tex]\sqrt{x + 2}= {-x}[/tex]

Square both sides

[tex]( \sqrt{x + 2})^2= ({-x})^2[/tex]

[tex]x + 2 = x^2[/tex]

Equate to 0

[tex]x^2 - x - 2 = 0[/tex]

Expand

[tex]x^2 + x -2x - 2 = 0[/tex]

Factorize:

[tex]x(x + 1) - 2(x + 1) = 0[/tex]

[tex](x -2)(x +1) = 0[/tex]

Split:

[tex]x - 2 = 0[/tex] or [tex]x + 1 = 0[/tex]

Answer:

x = 2, y = 23

x = 3, y = 39

x = 4, y = 56

x = 5, y = 67

Step-by-step explanation:

Given:

14x - 3 where $14 is per hours on part-time work and $3 is cost to and from work.

y = 14(2) - 3

y = 28 - 3

y = 23

y = 14(3) - 3

y = 42 - 3

y = 39

y = 14(4) - 3

y = 56 - 3

y = 53

y = 14(5) - 3

y = 70 - 3

y = 67

x = 2, y = 23

x = 3, y = 39

x = 4, y = 56

x = 5, y = 67

Answer:

-0.4.

Step-by-step explanation:

Average rate of change = difference in g(x) / difference in x

= (0 - 2) / (1 - (-4))

= -2/5 or -0.4.

The average rate of change of g over the interval -4 < t < 1 is -0.4

'A rate of change is a rate that describes how one quantity changes in relation to another quantity.'

According to the given problem,

Interval = -4 < t < 1

We know,

rate of change = [tex]\frac{y_{2}- y_{1} }{x_{2}-x_{1} }[/tex]

y₂ = 0

y₁ = 2

x₂ = 1

x₁  = -4

Rate of change = [tex]\frac{0-2}{1-(-4)}[/tex]

                          = [tex]\frac{-2}{5}[/tex]

                          = - 0.4

Hence, we can conclude, the average rate of change over the given interval is -0.4.
