What is the value x of 4×+67=143

Answer:

b. (16 , 4)

Step-by-step explanation:

f(x):   0 -> 1 , 4 -> 16

f⁻¹(x):  1 -> 0 , 16 -> 4

Answer:

(-3, -1/2)

Step-by-step explanation:

[tex]-\frac{2}{3} (-3) - 4*(-\frac{1}{2}) = 2-(-2) = 4[/tex]  > 0

Answer:

Clare starts with:

a*x^2 + b*x + c = 0

And she gets to:

(2*a*x + b)^2 = b^2 - 4*a*c

Now we want to show the final steps to solve the equation (isolating x)

First, we apply the square root to both sides:

[tex]\sqrt{(2*a*x + b)^2} = \sqrt{(b^2 - 4*a*c)}[/tex]

Because the square root has two solutions, (one negative and one positive), we will write:

[tex]2*a*x + b = \pm \sqrt{b^2 - 4*a*c}[/tex]

Now we subtract b in both sides:

[tex](2*a*x + b) - b = \pm \sqrt{b^2 -4*a*c} - b[/tex]

[tex]2*a*x = \pm \sqrt{b^2 -4*a*c} - b[/tex]

Now let's divide by 2*a in both sides:

[tex]2*a*x/(2*a) = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

[tex]x = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

Answer:

C

Step-by-step explanation:

1. Absolute values are in the shape of a V, so the answer is automatically C.

2. If you did not know that, you can see that the graph is a function because it passes the vertical line test. This rules out option A. By looking at the graph, you can see it passes the x-axis twice, meaning that it has 2 x-intercepts. This rules out option B. X-intercepts always have a y-coordinate of 0, so we can rule out option D. The only option left after this is C.

Answer:

32.2

Step-by-step explanation:

70 divided by 100 times 46

Answer:

C

Step-by-step explanation:

For one, it's negative so all positive answers can be eliminated.

Secondly, the y axis is hit on positive 3. No point even hits negative 3.

Knowing that, the only choice left is C.

Answer:

D.) 5625 pi inches squared

Step-by-step explanation:

square root of 625 = 25

25 x 3 = 75

A= pi r(squared)

A= 75squared pi

A= 5625 pi inches squared

Answer: D

Step-by-step explanation:

Answer:

If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.

Step-by-step explanation:

Answer:

Down below is the answer.

Step-by-step explanation:

So, lets remember that the pythagreon theorm is only useable in right traingles.

The formula for the pythagreons theorm is A^2+B^2=C^2

So basically, if this is not a right triangle, the two sides(4ft^2 and 3ft^2) will be equivelent to 5ft^2.

Lets solve the pythagroens theorm and plug in our values:

4^2+3^2=5^2

Now lets use the square roots:

16+9=25

COmbine the two numbers:

25=25

This is correct!

So yes, this is a right triangle.

HOpe this helps! :)

Answer:

Rectangle is the correct answer hope it helps you have a great day keep smiling be happy stay safe ☺️

A rectangle is a special type of parallelogram. Any parallelogram has two pairs of opposite parallel sides. A rectangle is a parallelogram where all four angles are the same, and all four angles are 90 degrees.

Keep in mind that not all parallelograms are rectangles, but any rectangle is always a parallelogram.

In slight contrast, a trapezoid has exactly one pair of parallel lines, while the other pair of opposite sides are not parallel. Triangles of any kind can be ruled out because they don't have any parallel sides at all.

Answer:

80

Step-by-step explanation:

yes

Answer:

By rounding

Step-by-step explanation:

48 % means 48 percent which 48 out of 100.

48% of 1220

= 48/100*1220

= 0.48*1220

=585.6 which is almost equal to 600

1) By rounding

Now if we round 48%  we get  50 % as 8 > 5 and 1 is added to 4 making it 5 in tens place leaving 0 in unit's place.

So 50% of 1220

0.50*1220= 610

Again rounding 610 would give 600 as 1 is less than 5 and we drop it out from the tens place leaving zero behind.

2) Complementary

IF we subtract 48% from 100% we get 52%.

So 52% of 1220 would be 634.4

IT again can be rounded in 2 ways Either 52% can be rounded to 50% and 634.4 can be rounded to 600.

Both would give 600
