Answer:

A: (2,5)

B: (4,8)

C: (8,6)

Answer:

Step-by-step explanation:

Two lines are perpendicular if the product of theirs slopes is equal -1:

y=m₁x+b₁   ⊥   y=m₂x+b₂   ⇒    m₁×m₂ = -1

y = -1/3x + 7   ⇒   m₁=-1/3

-1/3×m₂ = -1        ⇒    m₂ = 3

The y-intercept is b=-1 so the equation in  slope-intercept form:

                                                y = 3x - 1

Answer:

50 miles

Step-by-step explanation:

Step one

given data

let the total charge be y and the number of miles be x

Option A charges $20 per day

plus $0.10 per mile.

y= 20+0.1x---------------1

Option B charges $0 per day,

but $0.50 per mile

y= 0.5x---------------2

equate 1 and 2 we have

20+0.1x=0.5x

20=0.5x-0.1x

20=0.4x

divide both sides by 0.4

x= 20/0.4

x=50 miles

Answer:

[tex]\huge\boxed{slope=-\dfrac{7}{11}}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

[tex]m[/tex] - slope

[tex]b[/tex] - y-intercept

We have the equation in the general form [tex](Ax+By+C=0)[/tex].

Convert to the slope-intercept form:

[tex]7x+11y-2=0[/tex]    subtract 7x from both sides

[tex]11y-2=-7x[/tex]     add 2 to both sides

[tex]11y=-7x+2[/tex]     divide both sides by 11

[tex]y=-\dfrac{7}{11}x+\dfrac{2}{11}[/tex]

The general form of an equation of a line:

[tex]Ax+By+C=0[/tex]

The slope:

[tex]m=\dfrac{-A}{B}[/tex]

We have

[tex]7x+11y-2=0\\\\A=7;\ B=11;\ C=-2[/tex]

Substitute:

[tex]m=\dfrac{-7}{11}=-\dfrac{7}{11}[/tex]

Answer:

D equals 414

Step-by-step explanation:

414 is correct because to check do 414 divided by 3 to equal 138

MARK ME AS BRANLIEST

Answer:

its 414 because if you multiply 138 and 3 you get 414 then if you divide 414 and 3 you get 138

Step-by-step explanation:

Answer:

angle 1 = 100 degrees

angle 2 = 53 degrees

Step-by-step explanation:

diagonals of a rhombus bisect angles so angles 2 and 3 are both 53

angle 1 can be found by adding 37 and 53 and deducting that sum from 180

Answer:

37 and a 1/3

Step-by-step explanation:

3 glasses of lemonade=8lemons

1 glass of lemonade=2.66666667

14 glasses=37.33

you cannot have 37 and a 1/3

Answer:

8.25y + 14

Step-by-step explanation:

Given the expression

[tex]4\left(1.75y-3.5\right)+1.25y[/tex]

We are to simplify it as shown

Open the parenthesis

4(1.75y) - 4(3.5) + 1.25y

7y - 14 + 1.25y

Collect the like terms

7y + 1.25y - 14

8.25y + 14

Hence the required expression is 8.25y + 14

Answer:

8.25y−14

Answer:

So we divide 128 into 14 which is 9.14285714286 but that eo be impossible so next we round to the nearest number which is now 9 now we multiply 9 by 14 and that gives us 126

I believe this is the answer

The answer is 126 and second ........ 132

think about brinlist thank you

Answer:

Step-by-step explanation:

C

Answer:

I'm pretty sure the answer is B

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

We have both given slope and y-intercept. We can simply substitute the given slope and y-intercept in slope-intercept form.

Substitute m = -1 and b = - 5 in the equation.

[tex]y = - 1x - 5 \\ y = - x - 5[/tex]

We don't usually write 1x or -1x instead we write -x or x.

[tex]y = - x - 5[/tex]
