Hello!

We know the y-intercept (b) is 160. So let's find the slope!

Slope = rise / run

Slope = 120 - 160 / 1 - 0

Slope = -40/1 = -40

Forming the equation :

y = mx + b

y = -40x + 160

∴ The equation of the line in slope-intercept form is y = -40x + 160.

3x - 2y < 7

=============================================================

Explanation:

The dashed boundary line goes through (1, -2) and (3, 1)

Find the slope of this line using the slope formula.

[tex](x_1,y_1) = (1,-2) \text{ and } (x_2,y_2) = (3,1)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1 - (-2)}{3 - 1}\\\\m = \frac{1 + 2}{3 - 1}\\\\m = \frac{3}{2}\\\\[/tex]

The slope is 3/2 indicating we go up 3 and to the right 2.

--------------

Now use the point-slope template so we can determine the equation of the boundary line.

[tex]y - y_1 = m(x - x_1)\\\\y - (-2) = \frac{3}{2}(x - 1)\\\\y + 2 = \frac{3}{2}(x - 1)\\\\2(y+2) = 3(x-1) \ \ \text{ see note1 below}\\\\2y + 4 = 3x - 3\\\\2y - 3x = -3 - 4\\\\-3x+2y = -7\\\\3x-2y = 7 \ \ \text{ see note2 below}\\\\[/tex]

Note1: For this step, I multiplied both sides by 2 to clear out the fraction.

Note2: Multiply both sides by -1 so that the x coefficient is positive

--------------

The key thing to pull away from the previous section is that the boundary line equation is 3x - 2y = 7

The question from here is: "What do we replace the equal sign with?"

We need to pick either < or > since we have a dashed boundary. We won't have an "or equal to" portion.

Let's assume the inequality sign is <

3x - 2y = 7 turns into 3x - 2y < 7

To see if this works, we'll plug in the origin (0,0) to get...

3x - 2y < 7

3(0) - 2(0) < 7

0 < 7

The last inequality above is true, so 3x - 2y < 7 is also true when x = 0 and y = 0. It tells us that the origin is in the shaded region. This matches with what the graph shows.

Therefore, we have confirmed that 3x - 2y < 7 is indeed the case.

You could pick other test points. However the origin is the easiest to work with in my opinion. If the boundary went through the origin, then you'd have to pick another point like (0,1).

Answer: the amount of liters that would fill the glass tank's volume can not be found

Step-by-step explanation:

there is not enough information to find out how many liters could fill the glass tanks volume

The required volume of glass tank = Vb +Vw liters

Volume, is defined as the ratio of the mass of object to its density.

Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water.

Volume of pebbles = Vb
Volume of water = Vw
Volume of glass tank = Vg
Vg = Vb + Vw

Thus, the required volume of glass tank is = Vb + Vw liters

Step-by-step explanation:

y = 3 (x-1)(x+ 7 )    this graph will intercept the x axis  when y = 0

 0 = 3 ( x-1)(x+7)     so you can see this = 0   when x =1   or when x = -7

                                  these are the x-axis intercepts

         the vertex will be right in the middle between the intercepts found above    ....... at  x = -3    

          plug this value in to find the y coordinate   3 ( -3-1)(-3+7) = -48

                   vertex is   -3, -48

               the axis of symmetry is the value of the x coordinate of the vertex

Using a linear function, it is found that you would need roughly 24 hours of training to have a monthly pay of $1500.

A linear function is modeled by:

y = mx + b

In which:

Looking at the table, the pay increases $200 each 10 hours of work, hence the slope is:

m = 200/10 = 20

Then:

y = 20x + b

When x = 10, y = 1220, hence:

y = 20x + b

1220 = 20(10) + b

b = 1020.

Then the pay for x hours of training is:

y = 20x + 1020.

For a pay of $1500, we have that:

y = 20x + 1020.

1500 = 20x + 1020.

20x = 480

x = 24

You would need roughly 24 hours of training to have a monthly pay of $1500.

The statements that are true about the intervals of the continuous function are Options 2, 4  and 5

Looking at the values given, the intervals which satisfies the condition are known to be:

f(x)<=0 over the interval [0,2]

f(x)>0 over the interval (-2,0)

f(x)>=0 over the interval [2,∞)

Because:

Since the table with x  and f(x) values, we have to examine analyze the table and see the each option that is in line with f(x) or not .

Examine the values of x that is from -3 to 3, the f(x) values are both positive and negative . hence f(x)>0 is false over the interval (-∞,3)

Looking at the the interval from 0 to 2, the f(x) values are 0 and negative. Hence, f(x)<=0 over the interval [0,2]

When you look over the interval (-1,1), the f(x) values are said to be both positive and negative and as such, f(x)<0 is false over the interval (-1,1)

When you look at the interval (-2,0) , the f(x)  is positive and as such, f(x)>0 over the interval (-2,0)

Looking at the interval  [2,∞), f(x) is positive and as such, f(x)>=0 over the interval [2,∞)

Therefore, Option 2, 4 and 5 are correct.

Answer:

b - 140

Step-by-step explanation:

an angle bisector divides an angle in half

so

half of the angle is 70

the other half is 70

so

70 + 70 = 140

b is your answer

Answer: B. 140°

Step-by-step explanation:

Hi!

An angle bisector just cuts the angle in half.

Therefore, if one half is 70°, the other half is also 70°!

To find the measure of the angle just add them!

70° + 70° = ?

= 140°

Applying the definition of similar triangles, the value of x is determined as: 12.5.

In a triangle like the one shown above, the line that intersects the two sides of the triangle divides the two sides of the triangle to form similar triangles. Thus, their corresponding sides are proportional to each other.

Therefore, we would have:

(x + 5) / 5 = (10 + 4) / 4

(x + 5) / 5 = 14/4

4(x + 5) = 5(14)

4x + 20 = 70

4x = 70 - 20

4x = 50

x = 50/4

x = 12.5

W = XY                                       X =W/Y

To do this, we simply make X the subject of the formula in expressions on the left.

So, we have:

W = X - Y

This gives

X = W + Y

W = X/Z - Y

This gives

X/Z = W + Y

X = Z(W + Y)

W = (X - Y)/Z

This gives

X - Y = WZ

X = WZ + Y

W = XY

Answer:

0.04

Step-by-step explanation:

30+5+0.1+0.009 is 35.109

35.149 - 35.109= 0.04

35.149 = 30+5+0.1+ ____ +0.009

= 30 + 5 + 0.1 + x + 0.009

= 35.109 + x

x is the unknown value, so what number add to the 35.109 gives 35.149? That's what we're after.

35.149 = 35.109 + x

- 35.109 both side

0.04 = 0 + x

Thus, x = 0.04

(35.109 - 35.109 cancles each other & we get x on its own because 0.04 - 0 gives you 0.04)

Answer:

28 ft^2

Step-by-step explanation:

The room is in the shape of a square.  That means the base of the room (width and length) will have the same dimensions.

Length x Width = 49 ft^2

Length = Width

Length^2 = 49 ft^2

Length  = 7 feet

Width is also 7 feet

The height of the room is 4 feet, plenty for non-humans.  One wall area would be (7 ft)*(4 ft) = 28 ft^2

Boy is 22.5 feet high from the ground

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

The given question can be solved by sin, as value of perpendicular is to be evaluated and height and angle is provided. Let height from the ground be x

sin(22.5°) = x / 58

x = 58sin22.5 = 58(.38258)  =  22.5 feet high.
