Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

so, the fitting equation is

y = 2x² + 1

What is the solution of the equation 4(X+5)=X+8

BARSIC [14]

4 ( x + 5 ) = x + 8

4 * x + 4 * 5 = x + 8

4 x + 20 = x + 8

4 x - x = 8 - 20

3 x = -12

x = -12 / 3

x = - 4

hope this helps!

Please help me! Please! I am so lost! Pythagorean Theorem!

Ket [755]

Answer:

Part A- yes, because all 3 sides are Equal (each side is 5)

Part B- yes, each rectangle has the dimensions 12*5

Part C- yes- since the sides are 5 and 12 you can determine that the diagonal is 13, using they Pythagorean theorem $a^{2} +b^{2} =c^{2}$

$5^{2} +12^{2} =13^{2} \\25+144=169$ - true statement, so the lateral sides are rectangles, because the corners are 90

Part D- $4\sqrt{2}$ (it is a 45-45-90 triangle- so the hypotenuse is the side length times $\sqrt{2}$

Part E- the diagonal face as the largest area- dimensions are $4\sqrt{2} * 12\\$

the area would be $48\sqrt{2}$
