Answer:

y = x^2 +6x+14

Step-by-step explanation:

x = t - 3, y = t^2 + 5

x=t-3

Add 3 to each side

x+3 = t-3+3

x+3 =t

Substitute into the second equation

y = t^2 +5

y = (x+3)^2 +5

Foil the first term

y = (x+3) (x+3) +5

y = (x^2 +3x+3x+9) +5

y = x^2 +6x+9) +5

y = x^2 +6x+14

Step-by-step explanation: Slope-Intercept equations and graphs.

These are in y = mx + b form. M is slope. b is the y-intercept

For the y-intercept, you identify and label the place on the y-axis where the graphed line crosses it. That is one HINT to figuring out the equation that matches the graph. If the y-intercept is 0, there will be nothing after the 'x' term. If the y intercept ia any other number, that number will appear as a + or - after the 'x' term when you simplify the equation in y = mx + b form.

You have to draw the "stair steps" It helps you see slope. How many blocks up or down is the Rise. How many blocks from left to right is the Run.

Start by making a fraction Rise/Run if the Run is 1, the Slope is a whole number, the Numerator of the fraction (the 1 disappears from the equation).

(w-10x) (w+10x) Use the Identities to solve this question

Inessa [10]

<u>We are provided that</u> –

(w-10x) (w+10x)

<u>Applying identity</u> –

a² - b² = (a + b)(a - b)

$\qquad$ $\twoheadrightarrow\bf(w-10x) (w+10x)$

$\qquad$ $\twoheadrightarrow\bf w^2 - (10x)^2$

$\qquad$ $\twoheadrightarrow\bf w^2 -100 x^2$

Polygon ABCDE rotates 45° clockwise about point F to form polygon FGHIJ, shown in the figure. Find the measure of each angle of

castortr0y [4]

I think that the angles of the polygon would not change since there isn't a change of the shape, rather it position and rotation. The sum of each internal angle is found using S = 180(n-2), so
S = 180(5-2)
S = 180(3)
S = 540
540 / 5 = 108 degrees.
Therefore, all angles in the polygon is 108 degrees. I think this is what you meant right?

Artemon [7]

Answer:

6240 bushels

Step-by-step explanation:

You first find the area of the trapezoid. the formula is A= h(base 1+ base 2)/2

you will get 19968.235 as the area.

then you divide the area by 3.2 and round the answer to the nearest whole number and that is your answer.
