Answer:

y = -1/2x - 5

Step-by-step explanation:

To solve this (and questions like it), use the formula for the equation of a line:

y=mx+c, where y and x are any given co-ordinates, m is the slope, and c is the y-intercept.

Since we know that the slope is -1/2, we can plug this into our equation to replace m:

y=mx+c

y=-1/2x+c

To find c, we plug in our co-ordinate (4,-7), so that c is the only unknown, and we can solve for it:

y=-1/2x+c

-7=-1/2(4)+c

-7=-2+c

c=-5

Now that we know c, we can finish off our equation:

y = -1/2x + c

y = -1/2x - 5

Answer:

27/4

Step-by-step explanation:

Multiply both sides by 9/(-4).

9/−4 * −4/9 f = 9/−4 * −3

f = 27/4

Answer:

Answer is 3.2

Step-by-step explanation: you can take any percent and divide it by 100. So in this example you would divide 320/100 and it will give you 3.2

Answer:

− √ ( 9 + y ) 2 > 1

Explanation:

− √ ( 9 + y ) 2 , where  y < − 10

Simplify the expression,

− √ ( 9 + y ) 2 = − ( 9 + y ) = − 9 − y

When  y < − 10 , − y > 10

Subtract  9  from both sides,

− 9 − y > 1  Hence,

− √ ( 9 + y ) 2 > 1

The value of the expression -√(9 + y)² is -9 which is more than -10. So, it is incorrect.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ -√(9 + y)²

Simplify the expression, then we have

-√(9 + y)² = 0

(9 + y) = 0

9 + y = 0

y = - 9

Firstly, It says that the two triangles are similar .              

The scale factor is 2 as 12 / 6 = 2

25 + 85 = 110

180 - 110 = 70.

70 degrees

Answer:

A: 70

Step-by-step explanation:

Step One: This problem is tricky because it makes it seem more difficult than it really is. Because these angles are similar through the SAS theorem, their angles are the same. Similar means they are proportional triangles, but for this problem, the most important thing to know is that the angles of both triangles are the same. This means we can use the angles from the first triangle exactly the same way for the second triangle.

Step Two: Now that we have that out of the way, we also need to know that all angles in a triangle add up to 180 degrees.

Step Three: Ok, so we have all the information we need, so now we can solve the problem. As I've said, the angles from the first triangle are the same for the angles in the second triangle. So, we would do 85+ 25= 110.

Step Four: Lastly, we would do 180 (since all angles add up to 180)-110 to figure out the missing angle: 180-110=70 degrees.

Answer:

14 square units

Step-by-step explanation:

Equation:

Area of a triangle = h*b/2

Variables:

h = 4 units

b = 7 units

Solve:

h*b/2

= 4 units * 7 units /2

= 14 square units

Angle (5x+6): 81

Angle (8x-39): 81

Step-by-step explanation:

5x+6=8x-39

add 39 to both sides

5x+45=8x

-5x on both sides

45=3x

divide both sides by 3

x=15

Answer:

294 cm^2

Step-by-step explanation:

This question is asking for the surface area of all 6 sides of the Shoe box. Hence we will have to multiply all the dimensions with each other twice to get the surface area of all the sides.

9x10x2=180

9x3x2=54

10x3x2=60

Adding them together we get 294 cm^2.

Answer:

7

Step-by-step explanation:

126 g is what you originally had which=60% of whats left

you have to find out how many 10 wedges she can cut from the cheese that is left over

Work Shown:to find how much is left you have to multiply 126 by 60% remember when you multiply you have to move the decimal, and decimal is moved twice, so the answer would be 75.60 after you were done solving it and the number that is closest would be 70 so you would multiply 10 by 7=70 and the reason you pick that is because it is closer to 75.60.

So 7 is the answer.

Answer: 150

Step-by-step explanation:

A fixed cost is referred to as a cost that does not change with the output level that is, it doesn't change when there is a rose or reduction in the amount of goods or services that are produced.

Since the total cost function is given as

TC=3Q³ - 5Q² + 4Q + 150, we can infer that from the equation the fixed cost is 150 while the variable cost is 3Q³ - 5Q² + 4Q
