how do you add or subtract [-4]+6

Answer:

First one = 120

Second one = 54

Third one = 64

Step-by-step explanation:

For the first figure a triangle must all add up to 180 degrees so just do

180-60 which gives you 120

For the second one it is the same 104+ 22 = 126 then you do 180-126 which gives you 54

For the 3rd figure that straight line is equal to 180 so you do 180-154 which gives you 26 and because the other angle is a right angle we know it adds up to 90. 90+26 = 116 then finally you do 180 - 116 which gives you 64.

Hope this helps.

Answer:

[tex] y = -65x + 420 [/tex]

Step-by-step explanation:

Slope-intercept form equation is given as [tex] y = mx + b [/tex]

Where,

y = distance remaining

x = hours driven

m = slope/constant rate. In this case, the value of m would be -65. This means the distance will reduce at a constant rate of 65 miles per hour.

b = y-intercept, which is the initial value or the distance between the cities = 420

Plug in the values into the slope-intercept equation, to represent the distance y in miles remaining after driving x hours. You would have:

[tex] y = -65x + 420 [/tex]

The equation in slope intercept form is [tex]y =-65x + 420[/tex]

A linear function is a function whose value changes at a constant rate.

The given parameters are:

A linear function is represented as:

[tex]y = mx + c[/tex]

Where

So, the function becomes

[tex]y =-65x + 420[/tex]

Hence, the equation in slope intercept form is [tex]y =-65x + 420[/tex]

Answer:

D)0,4

Step-by-step explanation:

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

Explanation:

Let y = -3*f(-3) + 2*f(3)

The goal is to find the value of y as some single numeric value.

We know that f(x) is an odd function. This means that

f(-x) = -f(x)

For all x in the domain of f(x).

Based on that, we can say

f(-3) = -f(3)

and,

y = -3*f(-3) + 2f(3)

-1*y = -1*(-3*f(-3) + 2*f(3)) ... multiply both sides by -1

-y = 3*f(-3) - 2*f(3)

-y = 3*f(-3) + 2*(-f(3))

-y = 3*f(-3) + 2*f(-3)

-y = 3*7 + 2*7 .... f(-3) replaced with 7

-y = 21+14

-y = 35

y = -35

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

Here's a slightly different approach

f(-3) = 7

-f(3) = 7

Since f(-3) = -f(3)

We can then transform -f(3) = 7 into f(3) = -7 after multiplying both sides by -1

Therefore,

y = -3*f(-3) + 2f(3)

y = -3*7 + 2(-7)

y = -21 - 14

y = -35

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

There are probably other routes to solve this problem.

Whichever path you take, you should find that -3*f(-3) + 2f(3) = -35

I'm uploading a picture because it thought it had innapropriate words for some reason.

The transformation of a shape includes rotating and reflecting the shape;

(a) Image of BC after [tex]120^o[/tex] rotation

First, we calculate the angle of rotation, to make the hexagon lie onto itself

[tex]\alpha = \frac{\theta}{n}[/tex]

Where:

[tex]\theta = 360^o[/tex] --- angle at the center of the hexagon and the circle

[tex]n = 6[/tex] -- sides of hexagon

So, we have:

[tex]\alpha = \frac{360^o}{6}[/tex]

[tex]\alpha = 60^o[/tex]

This means that a [tex]60^o[/tex] rotation would make the hexagon lie onto itself.

We have that:

[tex]120^o = 60^o \times 2[/tex]

This means that the shape can be rotated [tex]60^o[/tex]  twice to achieve the [tex]120^o[/tex] rotation.

The image of BC at the first [tex]60^o[/tex] rotation is AB

The image of BC at the next [tex]60^o[/tex] rotation is FA

Hence, the image of BC after [tex]120^o[/tex] is FA

(b) Image of BC after reflection over line FC

Line FC divides the hexagon into equal halves.

So, when reflected over line FC, each segment would be flipped on the opposite segment.

The opposite of segment BC is DC.

Hence, the image of BC reflecting over FC is DC.

Answer: $3 : $4 or 3 : 4

Step-by-step explanation: To find the ratio of the cost of lemon juice in salad dressing, you’ll have to replace $13.50 or 13.5 to (135/10), which doesn’t affect the solution. Next, simplify (135/10) to get 27/2. After, divide 27/2 by 18, which is the other part of the ratio. (27/2 ÷ 18) Your final answer or result should end up as 3/4 but since we’re dealing with fractions 3:4, which is the simplified form of $13.50 : $18.00.

Answer: 54

Step-by-step explanation:

The value of m ∠C will be;

⇒ m ∠C = 54°

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In △ABC , m ∠A= 37° and m ∠B = 89° .

Now,

Since, In △ABC ,

⇒ m ∠A= 37° and m ∠B = 89°

We know that;

⇒ m ∠A + m ∠B + m ∠C = 180°

⇒ 37° + 89° + m ∠C = 180°

⇒ 126° + m ∠C = 180°

⇒ m ∠C = 180° - 126°

⇒ m ∠C = 54°

Thus, The value of m ∠C will be;

⇒ m ∠C = 54°

Answer:

22.6

Step-by-step explanation:

The cos of any angle is its adjacent over its hypotenuse:

cos 37 = 17.3 / x

We can multiple both sides by x to get x * cos 37 = 17.3 and then we can divide both sides by cos 37 to get x by itself:

x = 17.3 / cos 37

So solving for x, x is equal to about 22.6

Answer:

y = 60

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 20 when x = 10, then

20 = 10k ( divide both sides by 10 )

2 = k

y = 2x ← equation of variation

When x = 30, then

y = 2 × 30 = 60
