Answer:

y= -5/2x + 3/2

Step-by-step explanation:

(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.

(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.

Plugging in the two points, hence y= -5/2x + 3/2

Answer:

28h = 56

Divide by 28 on both sides

H = 2

Answer:

2

Step-by-step explanation:

28 per hour

56 per ? hours

Use the equation:

56 = 28 h

Divide 56 by 28

56 / 28 = 28 h /28

56/28 = 2

2 = h

Therefore, it will take 2 hours for the boat to cross a bay of 56 mil

Answer:

y=-5x+2

Step-by-step explanation:

Before we get started, we should identify slope-intercept form.

y=mx+b.

Step 1 : Isolate the y by dividing everything by 3.

(15x+3y=6)/3 = 5x+y=2

Step 2 : Move the x value to the right side.

y=-5x+2

Answer:

y=5x-2

Step-by-step explanation:

15x+3y=6

3y=15x-6....both side divide by 3

y=5x-2

Answer:

The hypotenuse is always directly opposite the right angle.

Step-by-step explanation:

Answer:

a. is the correct answer

Answer:

a=2

b=2

Step-by-step explanation:

This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

Inequality Notation: x≥-4

Step-by-step explanation:

An inequality is a mathematical statement that compares two expressions using the ideas of greater than or less than.

Solve 5x+2≥−18.

Subtract 2 from both sides.

5x+2−2≥−18−2

5x≥−20

Divide both sides by 5.

Answer:

A = 175, B = π/6, C = 345

Step-by-step explanation:

The given variation of the volume in the tank and time includes are;

At t = 0 the volume in the tank, y = Maximum volume, [tex]y_{max}[/tex] = 520 gallons

At t = 6 the volume in the tank, y = Minimum volume, [tex]y_{min}[/tex] = 170 gallons

The function that models the situation is y = A·cos(B·x) + C

Given that the function that models the situation is the cosine function, we have;

A = The amplitude = (The maximum - The minimum)/2

∴ A = (520 - 170)/2 = 175

A = 175

The period = The time to change from maximum to minimum = 2 × The time to change from maximum (t = 0) to minimum (t = 6)

∴ The period = 2 × (6 - 0) = 12

The period = 12 seconds = 2·π/B

∴ B = 2·π/12 = π/6

B = π/6

C = The vertical shift = Th minimum + A = (The maximum + The minimum)/2

∴ C = (520 + 170)/2 = 345

C = 345

Answer:

See attachment >_<

Step-by-step explanation:

Because the line includes the point [tex](0,3)[/tex], we'll begin our line at this coordinate.

The slope is [tex]7[/tex], or, [tex]\frac{7}{1}[/tex]. Slope is formatted in the [tex]rise[/tex] in the line over its [tex]run[/tex]. Or, [tex]\frac{rise}{run}[/tex]. This means the line rises [tex]7[/tex] units and runs [tex]1[/tex] unit.

From our beginning point, [tex](0,3)[/tex], move up seven units and then to the right one unit.

If this line was negative (it would have a negative slope), we would run to the left. However, we have a positive slope, so we will run to the right.

By doing this, we land on the point [tex](1,10)[/tex]. Draw a line through this point with our beginning coordinate [tex](0,3)[/tex]. This is our graphed line. I've attached a photo as well :)

Good luck ^^

Answer:

the answer is the 3rd one down fnivjgoibjmvkmkfmvk

Step-by-step explanation:

The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In a right-angle triangle, the measure of one angle will be 90 degrees.

If any two angle of the triangles are congruent, then the triangles will be a similar triangle.

In triangle ΔABC and ΔADB, we have

∠A = ∠A (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔADB are similar triangles.

In triangle ΔABC and ΔBDC, we have

∠C = ∠C (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔBDC are similar triangles.

Then the correct options are B and C.

The diagram is given below.

Answer:

Formula ~ A=(a+b)/2 x h

or 5 + 12/2 x 3 = 25.5

Answer ~ 25.5 (๑・ω-)～♥”

Answer:

D 0.75

Step-by-step explanation:

There are a total of 4 pairs: White-Summer, Black-Summer, White-Winter, and Black-Winter. There are a total of 8 socks.

The probability of pulling a black sock or a summer sock is the number of all black or summer socks divided by the total number of socks.

The number of black or summer socks includes 1 pair of White-Summer, 1 pair of Black-Summer, and 1 pair of Black-Winter.

This makes for 6 black or summer socks.

Divide 6 by 8 to get 0.75
