Answer:

1/2 is the slope of a line with equation y.

Answer:

36

Step-by-step explanation:

We have the summation:

[tex]\displaystyle{\sum_{i=1}^{9} 2i-6[/tex]

Essentially, we want to find the sum of (2i-6) from i=1 to i=9.

First, using summation properties, we can split this to:

[tex]=\displaystyle{\sum_{i=1}^{9} 2i+\displaystyle{\sum_{i=1}^{9} -6[/tex]

On the right, it will simply be -6 evaluated 9 times. We can also move the constant out from the left:

[tex]=\displaystyle{2\sum_{i=1}^{9} i+9(-6)[/tex]

For the summation on the left, this will simply be the sum (1+2+3+...+9). This yields 45. Therefore:

[tex]=2(45)+9(-6)[/tex]

Evaluate:

[tex]=90-54=36[/tex]

So, our final answer is 36.

Answer:

25

Step-by-step explanation:

It's what the others said, i'll change it if it's wrong

Based on the description of cost and the equation used, m in the equation would represent $25

m in the equation, y = mx + b, is the gradient. It is the figure that shows how much the cost will change in relation to time or activity.

In other words, m is the variable cost.

The only variable cost above is $25 which is variable because it increases per hour worked. m is there $25.

In conclusion, m is $25.

Look : angle 1 + angle 3 = 180°

because it is a straight line.

Thus ;

[tex]5x + 35 + 4x + 10 = 180[/tex]

Simplification

[tex]9x + 45 = 180[/tex]

Subtract sides 45

[tex]9 x = 180 - 45[/tex]

[tex]9x = 135[/tex]

Divided sides 9

[tex] \frac{9}{9}x = \frac{135}{9} \\ [/tex]

[tex]x = 15[/tex]

So x = 15°

_________________________________

angle 1 = 5x + 35°

angle 1 = 5 ( 15 ) + 35°

angle 1 = 75° + 35°

angle 1 = 110°

_________________________________

angle 1 + angle 2 = 180°

110° + angle 2 = 180°

Subtract sides 110°

angle 2 = 180° - 110°

angle 2 = 70°

Answer:

256

Step-by-step explanation:

By using power of a power rule, the result of [tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex] is 256.

Exponents formulas refer to the formulas that help solve exponents. Exponent of a number is represented in the form: [tex]x^{n}[/tex], meaning x is multiplied by itself for n times. Here,

x is called the "base"

n is called the "exponent" or "power"

[tex]x^{n}[/tex] is read as "x to the power of n" (or) "x raised to n"

Power of a power rule :  [tex](a^{m} )^{n}=a^{mn}[/tex]

Given exponential expression

[tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex]

[tex](4^{3} )^{2}[/tex] is in the form of power of a power rule [tex](a^{m} )^{n}=a^{mn}[/tex]

= [tex]4^{6}[/tex] × [tex]\frac{1}{4^{2} }[/tex]

= [tex]4^{4}[/tex] × [tex]4^{2}[/tex] × [tex]\frac{1}{4^{2} }[/tex]

= [tex]4^{4}[/tex]

= 256

The result of [tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex] is 256.

Answer:

Complementary Angles

Step-by-step explanation:

Complementary angles are angles whos measures add up to 90 degrees! The angles in the picture can also be described as adjacent angles, because they share the same vertex.

So these angles are technically both complementary and adjacent, but they are more specifically, complementary.

Answer:

n=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

3(n−5)=−21

Step 1: Simplify both sides of the equation.

3(n−5)=−21

(3)(n)+(3)(−5)=−21(Distribute)

3n+−15=−21

3n−15=−21

Step 2: Add 15 to both sides.

3n−15+15=−21+15

3n=−6

Step 3: Divide both sides by 3.

Answer: n= -2

Step-by-step explanation:

3(n−5)=−21

Divide both sides by 3.

n−5=  

3

−21

​  

Divide −21 by 3 to get −7.

n−5=−7

Add 5 to both sides.

n=−7+5

Add −7 and 5 to get −2.

Step-by-step explanation:

An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?

See, let us consider the sides as l as per question.

And, perimeter as p as per question.

We know that:-

The sum of all the boundary gives us the perimeter of the figure.

It is Equilateral Triangle, so the equation will be:-

[tex]l + l + l = p[/tex]

Now, adding it up, we get

[tex]3l = p[/tex]

So, 3l=p relates the side and perimeter.

Answer:

Domain: [-2, 0, 2, 4]

Range: [3]

Step-by-step explanation:

The domain of the function are all values of x that are plotted on the horizontal axis (x-axis), while the range are the corresponding y-values plotted on the vertical axis (y-axis).

Therefore,

Domain of the function = [-2, 0, 2, 4]

Range of the function = [3] (only 1 possible value of y can be seen as plotted on the gray]

Answer:

Option 2, y=-3/2x-4

Step-by-step explanation:

Solve with the point-slope formula: y-y1=m(x-x1). The line is perpendicular, meaning the slope of the new equation will be the oppposite reciprocal of the original slope.

First, we need to rewrite the original equation into standard form.

2x-3y=13

-3y=13-2x

y=-13/3+2/3x

From this, we can see that the slope here is 2/3. Since the line we're looking for is perpendicular, the opposite reciprocal of that slope is -3/2.

Now, we can plug in the coordinates we have into the formula (-6, 5), along with our slope (-3/2).

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

y-5=-3/2x-9

y=-3/2x-4

And to check, we can just plug the coordinates into our new equation:

Check:

(5)=-3/2(-6)-4

5=9-4

5=5
