Answers

Answer:

[tex]Area = 16[/tex]

Step-by-step explanation:

Given

[tex]A = (2,4)[/tex]

[tex]B = (4,0)[/tex]

[tex]D = (-4,0)[/tex]

Required

The area of the plot

The given coordinates show a triangle; and the area is calculated as:

[tex]Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2 + x_3y_1 - x_1y_3|[/tex]

[tex]Area = \frac{1}{2}|2*0 - 4*4 + 4*0 - -4*0 + -4*4 - 2*0|[/tex]

[tex]Area = \frac{1}{2}|-16 + 0 -16|[/tex]

[tex]Area = \frac{1}{2}|-32|[/tex]

[tex]Area = \frac{1}{2}*32[/tex]

[tex]Area = 16[/tex]

What is the value of z in the equation 2(2.5z − 58 + 43) = 176− 46? (3 points)

Answers

Answer:

32

Step-by-step explanation:

2(2.5z − 58 + 43) = 176− 46

5z - 116 + 86 = 130

5z -30 = 130

5z = 160

z = 160/5

z = 32

What value of w makes the equation 3(-4W - 5) = -7(5 + w) true?

Answers

Answer: W= 4

Step-by-step explanation:

The value of w will be 4.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The expression is;

3(-4W - 5) = -7(5 + w)

Now, Solve the expression as;

3(-4W - 5) = -7(5 + w)

3 × -4w - 3 × 5 = -7 × 5 + (-7) × w

-12w - 15 = -35 - 7w

Add 12w both side;

-12w - 15 + 12w = -35 - 7w + 12w

- 15 = 5w - 35

Add 35 we get;

- 15 + 35 = 5w - 35 + 35

20 = 5w

5w = 20

Divide 5 both side;

w = 4

Thus, The value of w will be 4.

When you divide both sides of an inequality by a negative number, you need to _____ the inequality symbol.

A. flip
B. eliminate
C. raise
D. multiply

Answers

Answer:

The correct option is option;

A. Flip

Step-by-step explanation:

When both sides of an inequality is divided by a negative number, it changes the sign of both numbers while their magnitude remain the same;

Therefore, if the right hand side of the inequality is lesser than the left hand side, when the signs of the left and right hand sides of the inequality changes after a division , by a negative number, we have;

The smaller right hand side of the inequality will then have a lesser negative magnitude than the left hand side of the inequality with a higher negative value and the left hand side (with the higher negative value) becomes lesser than the right and therefore, the symbol (sign) of the inequality is flipped

Therefore, when you divide both sides of an inequality by a negative number, you need to flip the inequality symbol.

For all values of x, f(x) = 2x-3 and g(x) = x^2 + 1 a) Find fg(x) Simplify and give your answer in the form ax^2 + b b) Find gf(x).

Answers

Answer:

fg(x) = 2x² - 1

gf(x) = 4x²-12x +10

Step-by-step explanation:

Given the functions f(x) = 2x-3 and g(x) = x^2 + 1

a) f(g(x)) = f(x²+1)

f(x²+1) = 2(x²+1) -3

f(x²+1)= 2x²+2 -3

f(x²+1) = 2x² - 1

fg(x) = 2x² - 1

Hence function fg(x) is 2x² - 1

b) gf(x) = g(2x-3)

g(2x-3) = (2x-3)² + 1

g(2x-3) = (2x-3)(2x-3) + 1

g(2x-3) = 4x²-6x-6x+9 + 1

g(2x-3) = 4x²-12x +10

gf(x) = 4x²-12x +10

Solve for X (Geometry) Need some help ASAP

Answers

Given:

The figure of a right triangle.

To find:

The measure of x.

Solution:

According to the altitude on hypotenuse theorem, the length of the altitude is the geometric mean of segments of the hypotenuse.

Let "h" be the height  of the altitude and it divides the hypotenuse if two pieces of lengths "a" and "b", then

[tex]h=\sqrt{ab}[/tex]

In the given figure, 14 is the height  of the altitude and it divides the hypotenuse if two pieces of lengths 24 and x. So, by using the altitude on hypotenuse theorem, we get

[tex]14=\sqrt{24x}[/tex]

Taking square on both sides.

[tex]196=24x[/tex]

[tex]\dfrac{196}{24}=x[/tex]

[tex]\dfrac{49}{6}=x[/tex]

Therefore, the value of x is [tex]\dfrac{49}{6}[/tex] units and its approximate value is 8.167 units.

what do you do on this i need it asap 40 + 56 ÷ p - q

Answers

Answer:

40 + 56/p - q

Step-by-step explanation:

This equation is weird. Your answer should be 40 + 56/p - q

The only thing that would change is writing "56 ÷ p" as a fraction.

Now, here's the weird part.

If you try to solve it after rewriting "56 ÷ p" as a fraction, your answer would look like this:

40p + 56 − qp

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

         p

Unless you have a math-based keyboard that would write 40p + 56 − qp over p as a fraction formatted like the equation shown above (instead of having to put a bunch of dashes so it looks like a long fraction line), then I'd stick with just typing 40 + 56/p - q.
