- 3x + 4 - 1 = 4x is an equation.

<h3>What is an equation?</h3>

The equal symbol (=) connects the two sides of the equation expression. 2x+1 is the left-hand side (LHS) of the equation, and 9 is the expression's right-hand side (RHS). The LHS value is equal to the RHS of the expression, as shown by the equal sign between LHS and RHS.

It is not an equation when 10x + 63 > 10. The expression's sign between the LHS and RHS in this case is not equal. We can therefore claim that not every expression is an equation. Linear inequalities are a class of expressions that fit this description.

- 3x + (4 -1) = 4x

- 3x - 4x = - 3

3x + 4x = 3

7x = 3

3/7 = x

Answer:

167.2 m/sec

Step-by-step explanation:

Convert 602 km/hr to m/sec, as follows:

602 km 1000 m

------------ * ----------------- = 602,000 m/hr

hr 1 km

Recall that 1 hr = 3600 sec. Convert 602,000 m/hr to m/sec:

602,000 m 1 hr

------------------ * ---------------- = 167.2 m/sec

1 hr 3600 sec

What is the equation of the ellipse with foci at (5, 0), (-5, 0) and vertices (9, 0), (-9, 0)?

forsale [732]

Answer: $\dfrac{x^2}{81}+\dfrac{y^2}{56}=1$

Step-by-step explanation:

General equation of ellipse : $\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}$

Given: Vertices of ellipse : (± 9,0)

Since the vertices are of the form (± a, 0).

i.e. a=9

Thus, the major axis is along x-axis.

Also, foci of the ellipse = (±5,0)

Since, foci is of the form (± c,0), i.e. c=5

Since

$c^2=a^2-b^2\\\\\Rightarrow\ 5^2= 9^2-b^2\\\\\Rightarrow\ b^2=81-25\\\\\Rightarrow\ b^2=56$

Equation of ellipse :

$\dfrac{x^2}{9^2}+\dfrac{y^2}{56}=1\\\\\Rightarrow\ \dfrac{x^2}{81}+\dfrac{y^2}{56}=1$

Hence, the required equation : $\dfrac{x^2}{81}+\dfrac{y^2}{56}=1$

Find p(-3) and p(5) for the function p(x) = 2x⁴ + 3x³ - 9x² + 16x + 13.

fredd [130]

Answer:

-35, 1493

Step-by-step explanation:

p(x) = 2x⁴ + 3x³ - 9x² + 16x + 13

p(-3) = 2(-3⁴) + 3(-3³) - 9(-3²) + 16(-3) + 13

-3² = 9

-3³ = -27

-3⁴ = 81

p(-3) = 2(81) + 3(-27) -9(9) - 48 + 13

p(-3) = 162 - 81 - 81 -48 + 13

81 + 81 = 162 therefore 162 - 81 - 81 cancels

-48 + 13 = -35

p(5) = 2(5⁴) + 3(5³) - 9(5²) + 16(5) + 13

5² = 25

5³ = 125

5⁴ = 625

p(5) = 2(625) + 3(125) - 9(25) + 80 + 13

p(5) = 1250 + 375 - 225 + 93

p(5) = 1250 + 150 + 93

p(5) = 1493
