Step-by-step explanation:

Answer:

Y = 4X - 6

Step-by-step explanation:

Slope of linear equation = change in Y / change in X

As Y is changing +4 units, with change in X +1 units.  [ -6 - (-2) ] / [ 1 - 0 ]

So, slope = 4

Y = A + BX

Y = A + 4X  , as B = slope & A = intercept

Putting values of X & Y (0,-6)

-6 = A + 4 (0)

A = -6

Hence, Equation : Y = 4X - 6

Step-by-step explanation:

Read the poem. excerpt from “Spring” by Christina Rossetti Frost-locked all the winter, Seeds, and roots, and stones of fruits, What shall make their sap ascend That they may put forth shoots? Tips of tender green, Leaf, or blade, or sheath; Telling of the hidden life That breaks forth underneath, Life nursed in its grave by Death. Which line from the poem contributes most to a hopeful tone? "Telling of the hidden life" "Frost-locked all the winter," "Life nursed in its grave by Death." "What shall make their sap ascend"

The numbers are 25, 34, and 17.

Let x be the first number, y be the second number, and z be the third number. We know that x + y + z = 76, z = x - 8, and y = 2z.

Substituting the second and third equations into the first equation, we get x + 2(x - 8) + (x - 8) = 76.

Simplifying the right side of the equation, we get 4x - 24 = 76.

Adding 24 to both sides of the equation, we get 4x = 100.

Dividing both sides of the equation by 4, we get x = 25.

Substituting x = 25 into the equation z = x - 8, we get z = 25 - 8 = 17.

Substituting x = 25 and z = 17 into the equation y = 2z, we get y = 2 * 17 = 34.

Therefore, the numbers are 25, 34, and 17.

Answer:

$160

Step-by-step explanation:

Diane sold some stuffs at a garage sale.

Let the total value of the money Diane made = x

She spent one-half of the money she made on a new bicycle.

Amount spent on a Bicycle = 1/2 × x = 1/2x

Next,

Amount left

= x - 1/2x = 1/2x

She spent one-half of what was left on a portable stereo.

Amount spent spent on Portable stereo

= 1/2 × 1/2x

= 1/4x

If Diane had $40.00 left,

Hence:

The fraction of what was left is calculated as:

= x - (1/2x + 1/4x)

= x - (3/4x)

= 1/4x

Hence:

1/4x = $40

We can find the value of x now.

1/4 × x = $40

x/4 = $40

x = $40 × 4

x = $160

Therefore, the amount she made from the garage sale is $160

Ans is y so find y by using formula for isoceles triangle that is 2 right triangles

Answer:

The inequality correctly matches the graph is -2 < x < 4 ⇒ B

Step-by-step explanation:

From the given figure

∵ There is a segment drawn from -2 to 4

∴ The starting point of the inequality is -2

∴ The ending point of the inequality is 4

∵ The endpoints of the segments are white circles (not shaded)

→ That means the signs of inequality without sign =

∴ The values of x are between -2 and 4

∴ The inequality is -2 < x < 4

∴ The inequality correctly matches the graph is -2 < x < 4

Answer:

33/2

Step-by-step explanation:

100

50 is half of 100 and 50% is half.

To write in slope-intercept form, you first need to get y by itself. To do this, subtract 7x from both sides of the equation.

Doing this gets you: y = 25 - 7x

Now that y is by itself, remember that slope-intercept form looks like this: y = mx + b

So, let's switch the right side.

y = -7x + 25

Slope intercept form is: y = -7x + 25

Rules for y in Slope-Intercept form:

y must be positive

y must be by itself (so, not 2y, or anything with it... just y)

Answer:

B. PK = 15, RJ = 9

Step-by-step explanation:

RQ = 3

PQ = 5

✔️In ∆JKL, Q is the centroid. According to the centroid theorem, thus:

⅓(RJ) = RQ

⅓(RJ) = 3

Multiply both sides by 3

RJ = 3*3

RJ = 9

✔️Also, based on the centroid theorem,

⅓(PK) = PQ

⅓(PK) = 5

Multiply both sides by 3

PK = 5*3

PK = 15

Step-by-step explanation:

Using the midpoint theorem, the perimeter of the triangle formed by joining the midpoints of the original triangle is exactly half the size in perimeter

What we mean in this case is that the perimeter of BAC IS two times the perimeter of EDF

perimeter of EDF is the sum of all the sides = 2 + 4 + 3 = 9

So the perimeter of BAC is 2 * 9 = 18
