Answer:

y = 4x - 14

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 2 ) and (x₂, y₂ ) = (6, 10 )

m = [tex]\frac{10-2}{6-4}[/tex] = [tex]\frac{8}{2}[/tex] = 4 , then

y = 4x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, 2 ) , then

2 = 16 + c ⇒ c = 2 - 16 = - 14

y = 4x - 14 ← equation of line

Answer:

D 72

Step-by-step explanation:

90(.8) = 72

The amount of time in minutes that the main character was on stage is D. 72 minutes

To determine the amount of time the main character was on stage during the 90-minute school play, we need to calculate 80% of the total duration.

To find 80% of a value, we multiply that value by 0.8 (which is the decimal equivalent of 80%).

In this case, we multiply 90 (the total duration of the play) by 0.8:

90 minutes x 0.8 = 72 minutes

Therefore, the main character was on stage for 72 minutes during the 90-minute school play.

The volume of cone is 324cubic inch, volume of Cuboid volume is equal to 4,080 cubic meter and cylinder Volume is 550 cubic cm

How would you define rounding?

Making a number simpler while maintaining a value that is close to what it was is known as rounding. Although less accurate, the outcome is simpler to utilize. Example: Since 73 is closer to 70 than to 80, 73, when rounded to the closest ten, equals 70. However, 76 rises to 80.

Given: A variety of solid shapes

To determine the volume and surface area of each solid

Solution:

Cone radius = 9 inch.

H height equals 12 inch

15 feet is the slant height.

Volume equals (1/3)πr²h = 324cubic inch.

Round to nearest tenth = 320 sq inch

Surface area equals πr² + πrl = π(81 + 135) sq inch = 679 sq inch

Round to nearest tenth = 680 sq inch

Cuboid volume is equal to 16 x 15 x 17 = 4,080 cubic meter.

Round to nearest tenth = 4,080 cubic meter

Surface area is equal to 2 (15 * 17 + 15 * 16 + 17 * 16) = 1,474 square meter.

Round to nearest tenth = 1,470 square meter

cylinder Volume = πr²h = π(5)²  * 7 = π 175 cubic cm = 550 cubic cm

Round to nearest tenth = 550 sq cm

cylinder Surface area is equal to  2πr(r + h ) = 10π (5+7) = 377 sq cm.

The age of mother and daughter are 10 and 40 years old, respectively.

Given that,

Mother is 4 times her age. Her daughter's age plus her daughter's age after 8 years equals 66 years.

It can be written into equation as :

Let Mother's age be x

Let daughter's age be y

By using algebra,

x =4y --------> (1)

(x+8) + (y+8) = 66

x+ y = 66-16

x + y = 50--> (2)

Now substitute x = 4y in (2) we get

x + y = 50

4y + y = 50

5y= 50

y = 10 years which means x = 4y = 40 years

You need to find the slope of each line to determine if they are parallel. Beginning with AB, you do the formula for slope and get a value of -1/3. Next, you do CD and find it also has a slope of -1/3. Because both of these lines have equal slopes it makes them parallel because they will both be traveling at the same rate and will never get closer or further from each other.

If a bottle of perfume on sale for $30 after a discount of 25%, then the original price of the perfume is $40

The selling price of the perfume = $30

The percentage of discount on perfume = 25%

Consider the original price of the perfume = x

Then the equation will be

[ Original price - Original price × 25%] =  The selling price of the perfume

Substitute the values in the equation

[ x - x×(25/100) ] = 30

( 1 - 25/100)x = 30

( 1 - 0.25)x = 30

0.75x = 30

x = 30 / 0.75

x = $40

Answer:

The equation of the line in fully simplified slope-intercept form is [tex]y=-0.4x-4[/tex]

Step-by-step explanation:

The equation of the line in fully simplified slope-intercept form can be calculated as follows ?

The first step is to calculate the slope [tex]m[/tex] of the given line using the slope formula as follows

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Take two coordinates on the given line

[tex](-5,-2)~ \text{and} ~(5,-6)[/tex]

Substitute [tex]-6[/tex] for [tex]y_{2}[/tex], [tex]-2[/tex] for [tex]y_{1}[/tex], [tex]5[/tex] for [tex]x_{2}[/tex], [tex]-5[/tex] for [tex]x_{1}[/tex]  in the slope formula

[tex]m=\frac{-6-(-2)}{5-(-5)}[/tex]

Take out the brackets in the numerator and the denominator at the right side of the equation

[tex]m=\frac{-6+2}{5+5}[/tex]

Simplify the numerator and the denominator at the right side of the equation

[tex]m=\frac{-4}{10}[/tex]

Convert the value of [tex]m[/tex] into decimal

[tex]m=-0.4[/tex]

The second step is to find the slope-intercept form of the given line by the point-slope form formula as follows

[tex]y-y_{1}=m\cdot (x-x_{1})[/tex]

Take any coordinates on the given line,  take [tex](-5,-2)[/tex]

Substitute [tex]-2[/tex] for [tex]y_{1}[/tex],  [tex]-5[/tex] for [tex]x_{1}[/tex], [tex]-0.4[/tex] for [tex]m[/tex]  

[tex]y-(-2)=-0.4\cdot (x-(-5))[/tex]

Take out the inner bracket on the right side of the equation

[tex]y-(-2)=-0.4\cdot (x+5)[/tex]

Take out the bracket on the left side of the equation

[tex]y+2=-0.4\cdot (x+5)[/tex]

Expand the right side of the equation

[tex]y+2=-0.4x -2[/tex]

Substract [tex]2[/tex] from both sides of the equation

[tex]y+2-2=-0.4x -2-2[/tex]

Simplify the equation

[tex]y=-0.4x -4[/tex]

Hence the equation of the line in fully simplified slope-intercept form is [tex]y=-0.4x-4[/tex]

Permutations and combinations are ways of representing groups of objects by selecting them  and sub-setting them into sets. It defines different ways of arranging a particular data group. When we choose data or objects from a particular group, it is called a permutation and the order in which they are presented is called a combination. Both concepts are very important in mathematics.

We are given that In a soccer match;

A tie at the end of two overtime periods leads to a "shootout" with five kicks taken by each team from the penalty mark.

Each kick must be taken by a different player

[tex] x = \dfrac{\log 5}{\log 7} [/tex]

Step-by-step explanation:

[tex] 7^{2x} - 4 \times 7^x = 5 [/tex]

[tex] 7^{2x} - 4 \times 7^x - 5 = 0 [/tex]

[tex] (7^x)^2 - 4(7^x) - 5 = 0 [/tex]

This is a quadratic equation in 7^x.

Let u = 7^x.

Substitute u for 7^x to see the quadratic equation more clearly.

[tex] u^2 - 4u - 5 = 0 [/tex]

Now we have a factorable quadratic equation in u.

[tex] (u - 5)(u + 1) = 0 [/tex]

[tex] u - 5 = 0 [/tex]  or  [tex] u + 1 = 0 [/tex]

[tex] u = 5 [/tex]  or [tex] u = -1 [/tex]

Now substitute back 7^x for u.

[tex] 7^x = 5 [/tex]  or  [tex] 7^x = -1 [/tex]

[tex] 7^x = -1 [/tex] does not have a real solution.

Continue solving [tex] 7^x = 5 [/tex] for x.

Step-by-step explanation:

Given equation:

[tex]7^{2x}-4 \cdot 7^x=5[/tex]

[tex]\textsf{Apply exponent rule} \quad a^{bc}=(a^b)^c:[/tex]

[tex]\implies (7^x)^2-4 \cdot 7^x=5[/tex]

Subtract 5 from both sides:

[tex]\implies (7^x)^2-4 \cdot 7^x-5=0[/tex]

[tex]\textsf{Let \; $u = 7^x$}:[/tex]

[tex]\implies u^2-4u-5=0[/tex]

Factor the quadratic:

[tex]\implies u^2+u-5u-5=0[/tex]

[tex]\implies u(u+1)-5(u+1)=0[/tex]

[tex]\implies (u-5)(u+1)=0[/tex]

Apply the zero-product property:

[tex]\implies u-5=0 \implies u=5[/tex]

[tex]\implies u+1=0 \implies u=-1[/tex]

[tex]\textsf{Substitute back in \; $u = 7^x$}:[/tex]

[tex]\implies 7^x=5[/tex]

[tex]\implies 7^x=-1 \quad \textsf{is not valid as $7^x > 0$}.[/tex]

Therefore, the only valid solution is:

     To solve this question, we can see that the given function and the answer options are in different equation forms. The given is in standard, but the answer options are in vertex. We will change the given function into vertex form. This is also known as completing the square.

y = x² + 6x + 7

y = (x² + 6x) + 7

y = (x² + 6x + [tex]\frac{6}{2} ^2[/tex] -  [tex]\frac{6}{2} ^2[/tex]) + 7

y = (x² + 6x + 9) + 7 - 9

y = (x² + 6x + 9) - 2

     y = (x + 3)² - 2

     Now, we can see the correct answer option is the first one;

                 "y=(x+3)2−2"
