Answer:

y = -5x + 14

Step-by-step explanation:

Parallel lines have the same slope, and their equations are identical except for the value of the constant (which in turn is the y-intercept).

Both lines have the slope m = -5.  Start with y = mx + b, or y = -5x + b.  Then substitute 3 for x and -1 for y:

-1 = -5(3) + b, or:

14 = b (the y-intercept is 14)

Then the desired equation is y = -5x + 14.

the answer is between 11 and 12

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid =   x (sum of the lengths of the parallel sides) x height

Perimeter =  sum of lengths of sides of a trapezoid

Answer:

y = (x + 5)2 – 10 in  standard form 2 x − y = 0

Answer:

See explanation for answer.

Step-by-step explanation:

Ok, so I'm not entirely sure if this answer is correct but for the equation y = (x + 5)2 – 10 I beleive that the equation in standard form would be y = 2( x + 5 ) - 10.

I hope this helps!

Answer:

  583.4 cm³

Step-by-step explanation:

We have the base dimensions, so enough information to find its area:

  A = s²

  A = (10 cm)² = 100 cm²

__

The height of the triangle is found by solving triangle AMV for the distance MV. That is found from the trig relation ...

  Tan = Opposite/Adjacent

  tan(68°) = MV/AM

The length of AM is half the diagonal of the square base, so is (10√2)/2 = 5√2. The length of MV is ...

  MV = AM·tan(68°) = 5√2·tan(68°) ≈ 17.50

So, the volume of the pyramid is ...

  V = (1/3)Bh

  V = (1/3)(100 cm²)(17.50 cm) ≈ 583.4 cm³ . . . . volume of the pyramid

Answer:

The second deal is better. It is $2.042 per gallon

Step-by-step explanation:

$11/5 and 51.05/25 are the deals.

Let's multiply the first deal by 5/5.

That is $55 per 25 gallons and the other deal is $51.05 per 25 gallons.

So the second deal is better.

Now lets divide 51.05 by 25 to find out how much dollars per gallon

51.05 / 25 = 2.042, so it is $2.042 per gallon.

Answer:

d < -7

Step-by-step explanation:

-38d - 57 > -19d + 76

Add 19d to both sides

-19d - 57 > 76

Add 57 to both sides

-19d > 133

Divide both sides by -19

(when multiplying or dividing by a negative the inequality is reversed)

d < -7

Answer:

d < -7

Step-by-step explanation:

-38d - 57 > -19d +76

Add 19d and 57 to both sides

-19d > 133

Divide both sides by -19 (dividing by negative flips the inequality sign)

d < -7

Answer:

the answer for this equation is c. -2

Answer:

y = 12

Step-by-step explanation:

The segments are equal in length, SR = TR, so set up an equation:

[tex]\frac{y^2}{12}=y[/tex]

Multiply by 12.

[tex]y^2=12y\\y^2-12y=0[/tex]

Factor out the y on the left side.

[tex]y(y-12)=0[/tex]

There are two solutions:  y = 0 and y = 12.  The y = 0 solution makes no sence (segment SR can't have a length of 0).  The other solution, y = 12, works just fine.

Answer:

T = 5 (H = 7, M = 1); T = 7 (H = 4, M = 2); T = 9 (H = 1, M = 3)

Step-by-step explanation:

We know MH+MH+MH=TM

MH is a two digit number, and TM is also a two digit number.

MH+MH+MH=3*(MH)<100

3M<=9, meaning that M could be 1, 2, or 3.

If M=1, MH+MH+MH=3(10+H)=30+3H=TM=10*T+1

30+3H=10T+1, so 3H must include 1 in one's digit.

The only possibility is that 3H = 21, then H = 7

MH+MH+MH=17+17+17=TM=51, T = 5

If M=2, MH+MH+MH=3(20+H)=60+3H=TM=10T+2

60+3H=10T+2, so 3H must include 2 in one's digit.

The only possibility is 3H = 12, then H = 4

MH+MH+MH=24+24+24=72, T = 7

If M=3, MH+MH+MH=3(30+H)=90+3H=TM=10T+3

90+3H=10T+3, so 3H must include 3 in one's digit.

The only possibility is 3H = 3, then H =1

MH+MH+MH=31+31+31=93, T=9

We will see that if we define M = 2, and H = 4, the value that T takes is T = 7

We know that:

MH + MH + MH = TM

We can write this as:

M*10 + H + M*10 + H + M*10 + H = T*10 + M

30*M + 3*H = T*10 + M

30*M - M + 3*H = T*10

(29*M + 3*H)/10 = T

Now we need to find two values for M and H such that T is a digit.

For example, if M = 2 we have:

(29*2 + 3*H)/10 = T

(58 + 3*H)/10 = T

Now we can take H = 4, then we get:

(58 + 3*4)/10 = T

(58 + 12)/10 = T = 7

In this case, we found that a possible value of T is T = 7.
