What is the slope of the line graph

Answer:

[tex]Question \: 1: \: let \: the \: question \: mark \: be \: n \\ n = 63 \\

Question \: 2: \: the \: error \: the \: student \: made \: is \: \\ 4x + 40 = 6x - 10 \: insteade \: of : \\ 4x + 40 + 6x - 10 = 180. \\

Question \: 3: \: x = 15 \\

Question \: 4: m( GFC)

= 80. \\ [/tex]

Step-by-step explanation:

[tex]let \: the \: unknown \: be \: n \\ then \\ 87 + n = 150 \\ n \: = 150 - 87 = 63. \\ the \: mistake \: is \: by \: the \: expression : \\ 4x + 40 = 6x - 10 \: insteade \: of : \\ 4x + 40 + 6x - 10 = 180. \\ 10x = 150 \\ x = 15. \\ 6x - 10 = 6 \times 15 - 10 \\ GFC

= 80. \\ [/tex]

Answer:

m = -1

Step-by-step explanation:

3(m + 2) = -( 6- m) + 10​

Distribute

3m +6 = -6+m +10

Combine like terms

3m+6  = m+4

Subtract m from each side

3m-m+6 = m+4-m

2m+6 = 4

Subtract 6 from each side

2m+6-6 = 4-6

2m = -2

Divide by 2

2m/2 = -2/2

m = -1

Answer:

QR does indeed = SP

Step-by-step explanation:

The number of 5ths that equals 9 is gotten bus using multiplication property of equality by multiplying 9 by 5 to give; 45

We want to find the number of 5ths that equals 9. We can express this as;

¹/₅x = 9

Where x is the number that is multiplied with one - fifth to equal 9.

To solve it, we will apply multiplication property of equality by multiplying both sides by 5 to get;

x = 45

Thus, the number of 5ths that equals 9 is 45.

Answer:

2.91 mph

Step-by-step explanation:

To find the unit rate you just divided 35 miles into 12.

35 ÷ 12 = 2.91

so x^2-10=0

we add 10 to both sides of the equation  x^2 = 10

then take the square root of both sides of the equation to eliminate the exponent on the left side  x = ± √10

The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10

the result can be shown in multiple forms

Exact Form :x=√10,−√10x=10,-10

Decimal Form: x=3.16227766…,−3.16227766

Answer:

(-5)^3 = -125

Step-by-step explanation:

(-5)^3

= (-5) × (-5) × (-5) = -125

= (-5)^3 = -125

(-5) to the power of 3 is just (-5) multiplied by itself 3 times so (-5) to the power of 3 is (-5)^3 which is -125

Step-by-step explanation:

it's quite easy to go around this problem.

first you gotta consider the negative (-) sign..

you know when a negative sign multiplies another negative sign you'll get a positive sign.

example

-5*-5= ?

since you know the negative sign would turn to a positive sign when they multiply each other.

and be mindful of problems with different signs like

−6×9, you'll definitely get a negative answer

Now to your question.

(−5)^3, if you're struggling with composite expression,all you need is to break it down to simplified form

since it's -5 raised to the power of 3

you can as well write it as -5*-5*-5 (pay attention to the negative sign). then go through with your calculations

if you do it correctly, you'll arrive at the answer

-125

Answer:

Step-by-step explanation:

Answer:

let [tex]x[/tex] = height of rectangle

Given:

Therefore,

Shaded area = area of rectangle - area of circle

Area of rectangle = length × height

                             = [tex]3x \times x[/tex]

                             = [tex]3x^2[/tex]

Area of circle = [tex]\pi r^2[/tex]

                       [tex]=\pi \left(\dfrac{1}{2}x\right)^2[/tex]

                       [tex]=\dfrac14\pi x^2[/tex]

[tex]\implies \textsf{shaded area}=3x^2-\dfrac14\pi x^2[/tex]

If the radius = 2 cm, then the diameter ([tex]x[/tex]) = 4 cm

Substituting [tex]x = 4[/tex] into the equation:

[tex]\implies \textsf{shaded area}=3(4)^2-\dfrac14\pi (4)^2[/tex]

[tex]\implies \textsf{shaded area}=48-4\pi[/tex]

[tex]\implies \textsf{shaded area}=4(12-\pi) \textsf{ cm}^2[/tex]
