anyone know this? cuz i'm confused

Answer:

y=-1/6x-2

Step-by-step explanation:

Lets find the slope of the given line

6x-7=y,m=6

The slope of the perpendicular line would be=-1/6

Using the point-slope form y-y1=m(x-x1)

y--1=-1/6(x--6)

y+1=-1/6(x+6)

6y+6=-x-6

6y=-x-6-6

6y=-x-12

y=-1/6x-2

Notice that the second polynomial is subtracted from the first.

It's important to understand that the minus sign outside the

second set of parenthses can be thought of as a -1.

So we need to distribute the -1 through each of

the terms in the second set of parenthses.

So our problem will now look like 5x² + 25x + 30 - 3x² - 6x - 3.

Now, we combine like terms.

So we have 2x² + 19x + 27.

We know he traveled 4.8 miles in 3 hours.  However, since the question asks for his speed in miles per hour, we only want to know how far he travels in one hour.  To find this, we just divide 4.8 by three, and find that he is traveling at 1.6 miles per hour.

Answer:

Speed = 1.6

Step-by-step explanation:

[tex]Speed=\frac{Distance}{Time} \\\\Speed = \frac{4.8}{3}=1.6[/tex]

Answer:

The ratio of black shirts to blue shirts is 7:2

Step-by-step explanation:

Ratios

A ratio is a way to compare two numbers of the same kind. We use ratios to compare things of the same type. For example the ratio of boys and girls in a class. Ratios as expressed in the form n:m.

There are 36 red shirts, 12 blue shirts, 42 black shirts, and 60 white shirts. It's required to calculate the ratio of black shirts to blue shirts. We'll use fractions to express the relationship. The fraction will divide 42 by 12:

[tex]\frac{42}{12}[/tex]

Simplifying by 6:

[tex]\frac{42}{12}=\frac{7}{2}[/tex]

Thus, the ratio of black shirts to blue shirts is 7:2

Answer:

black shirts to blue shirts is 7:2

Step-by-step explanation:

Answer:

199.75km

Step-by-step explanation:

Step one:

given data

We are told that the time of travel is from

8:36- to 10:57

which is 2 hours 21 minutes

Hence the time taken is 2.35 hours

the speed is 85km/h

Step two:

From the expression

speed= distance/time

85= distance/2.35

distance= 85*2.35

distance= 199.75km

Answer: it traveled a distance of 199.75Km

Step-by-step explanation:

From the question , Let 0836 be 8:36

and 1057 be 10:57

Time of departure= 8:36

Time of arrival = 10:57

Time traveled = 10:57- 08:36= 2 Hours 21 minutes

changing trhe time to hours becomes 21/60 = 0.35 hours + 2 HOURS = 2.35 hours

Step 2

Speed = Distance / Time

Distance = Speed x Time

=85 km/hr x 2.35 hours

=199.75Km

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Where the 2 lines intersect is the solution set to the systems of equations.

If the lines are the same, they will have infinite solutions (will always intersect).

If the lines are parallel, they will have no solutions (will never intersect).

According to the graph, we see that the lines are parallel. Therefore, the systems has no solutions.

Answer:

3.6%

Step-by-step explanation:

We are solving the above question, using the simple interest Formula:

I = PRT

Where

I = Interest = $9

P = Principal = $150

R = Interest rate = ??

T = Time in years = 20 months

We convert this to years

12 months = 1 year

20 months = x

x = 20/12

x = 1.67 years

Hence, making R the subject of the formula

R = I/PT

R = 9/150 × 1.67

R = 9/250.5

R = 0.0359281437

Converting to percentage

R = 0.0359281437 × 100

R = 3.59281437%

R = 3.6 %

The simple interest rate she is earning is 3.6%

Answer:

Part(A): The expression which represents the number of hours Matthew played soccer in a full week is [tex]5h + 6.5[/tex]

Part(B): the expression models her purchase is [tex]35.79-3b[/tex].

Step-by-step explanation:

Consider the provided information.

Part(A):

Matthew plays soccer for h hours per day for five days and he played a soccer tournament for a total of 6.5 hours.

So the required expression is: [tex]5h + 6.5[/tex]

Where 5h represents time spent in 5 days and 6.5 is the hours of the soccer tournament.

Part(B):

Mariah purchases three hair barrettes by using a gift card.

Let the cost of each barrette is b.

So the cost of 3 barrettes is: [tex]3b[/tex]

She uses a gift card with a balance of $35.79. Therefore subtract  [tex]3b[/tex] from $35.79.

Her purchase can be expressed as:

[tex]35.79-3b[/tex]

Hence, the required expression is [tex]35.79-3b[/tex].

Answer:

5h + 6.5

Answer:

For 3x-2+4=x-6

[tex]3x - 2 + 4 = x - 6 \\ 3x - x = - 6 - 4 + 2 \\ 2x = - 8 \\ x = \frac{ - 8}{2} \\ x = - 4[/tex]

for x+8=5x+6

[tex]x + 8 = 5x + 6 \\ x - 5x = 6 - 8 \\ - 4x = - 2 \\ x = \frac{ - 2}{ - 4} \\ x = \frac{1}{2} [/tex]

Answer:

42 cm²

Step-by-step explanation:

Length of the shaded rectangle = 7 cm

Width of the shaded rectangle= 7 - (0.5 + 0.5) = 7 - 1

Width of the shaded rectangle = 6 cm

Area of the shaded rectangle = L × W

Area = 7 × 6 = 42 cm²

Answer:

(6, 2.5 )

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k substitute the coordinate point (5, 3 ) into the equation, that is

3 = [tex]\frac{k}{5}[/tex] ( multiply both sides by 5 )

15 = k

y = [tex]\frac{15}{x}[/tex] ← equation of variation

Using (x, 2.5 ) with y = 2.5 , then

2.5 = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )

2.5x = 15 ( divide both sides by 2.5 )

x = 6

Thus point is (6, 2.5 )

Answer:

ok so

Step-by-step explanation:

8x + 7 + 7x - 2=90=>

=> 15x+5= 90

=> 15x=90 - 5=>

=> 15x =85= x= 5.6666...

Hey there!

“8x + 7 + 7x – 2 = 90”

• FIRST: COMBINE your LIKE TERMS

(8x + 7x) + (7 – 2) = 90

‘8x + 7x = 15x’

‘7 – 2 = 5x’

“15x + 5 = 90”

• SECOND: SUBTRACT by 5 on BOTH SIDES

15x + 5 – 5 = 90 – 5

CANCEL out: 5 – 5 because that gives you 0

KEEP: 90 – 5 because it helps us solve for your x-value

‘90 – 5 = 85’

NEW EQUATION:

“15x = 85”

• THIRD: DIVIDE by 15 on BOTH SIDES

15x/15 = 85/15

CANCEL out: 15/15 because that equals 1

KEEP: 85/15 because it gives us our x-value

Reduce: 85/15 and it gives us: x

Answer: x = 17/3 ☑️

Answer:

Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]

Step-by-step explanation:

We need  to Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex]

(Note: Considering 2d^2 instead of 2d as thinking it typo error)

Subtracting from means we have to subtract [tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)[/tex]

Subtracting:

[tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)\\=4c^2 + 3cd + 2d^2 +3c^2 - 12cd + 4d^2[/tex]

Combining like terms (Like terms are those that have same variables like 4c^2 and 3c^2 are like terms, 3cd and -12cd are like terms, 2d^2 and 4d^2 are like terms)

[tex]=4c^2+3c^2 + 3cd-12cd + 2d^2+4d^2 \\=7c^2-9cd+6d^2[/tex]

So, Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]

Answer:

A, y-intercept = (0,24)

Step-by-step explanation:

The y intercept is the one without a variable. You have to solve to find it in the other options.

Answer:

The first choice would be the best one.

Step-by-step explanation:

The y intercept occurs when x = 0 of the given polynomial.

All 3 answers will give you the correct answer. The y intercept is (0,24)

but the first one will be the quickest because all you need to do to find it is just eliminate any term with x in it.

2x^2 when x = 0 is 0

16x when x = 0 is 0.

That only leaves m(0) = 24 found just by looking at it.

The second one also works. 2 (0+4)^2 -  8 = 32 - 8 = 24

And the third one as well 2(6)(2) = 24

Answer:

-0.8 is the correct answer for this question

Step-by-step explanation:

mark me as brainliest

Answer:

t=-0.8

Step-by-step explanation:

You want to get the 't' by itself, so you will subtract 5 from both sides

5.25t=16.5t+9

Now, you want to subtract 16.5t from both sides

-11.25t=9

now you divide -11.25 from both sides.

t=-0.8
