Triangle RST, with vertices R(-7,-8), S(-3,-7), and T(-6,-2), is drawn on the coordinate grid below. What is the area, in square units, of triangle RST?

Answer:

The answer is 19.25

Step-by-step explanation:

Key skills needed: Fraction operations, decimal conversion

1) We are given the hint to use 9 as "b", and we get:

---> [tex]a = \frac{16}{8}(9) + \frac{10}{8}[/tex]  

Let's do  [tex]\frac{16}{8}(9)[/tex]

--> [tex]\frac{16}{8}[/tex] is the same as [tex]16[/tex] ÷ [tex]8[/tex]

16 divide by 8 is 2.

2) This means that it would be  ---> [tex]2(9)[/tex]  which is simply 2 times 9.

2 times 9 = 9 + 9 = 18

3) With that result, it would be  ---> [tex]a = 18 + \frac{10}{8}[/tex]

Now, do [tex]\frac{10}{8}[/tex] (10 divided by 8)  ---> Get 1.25

4) 18 + 1.25 = 19.25, so --> [tex]a = 19.25[/tex] is the answer

Hope you understood and have a nice day!!   :D

Answer:

No

Step-by-step explanation:

If there's a repitition in the X values of the pair   (x,y), it is not a function.

Step-by-step explanation:

Answer:

The fundamental theorem of algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. polynomials with real coefficients are included in this since every real number is a complex number with its imaginary part equal to zero.

Answer:

15in

Step-by-step explanation:

Convert the 15 ft to inches (180) and then set up the proportion.\frac{1}{12} = \frac{x}{180}121=180x .  Cross multiply to get that 12x = 180 and x = 15 inches.

Answer:

2

Step-by-step explanation:

y^m x y^n = y^m+n

so y^-4 x y⁶ = y^-4+6

-4+6=2

Answer:

-44

Step-by-step explanation:

Basically It's like 4x11, but you put a negative sign.

Option B is correct that is false.

We have been given a figure we need to tell that the two lines are perpendicular.

Lines are perpendicular if they meet at the right angle.

Line CD is perpendicular AB to vice-versa is not true.

Hence, Option B is correct

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .

The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other.

Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.

Answer:

Any real number strictly larger than 9 and strictly less than 21.

Step-by-step explanation:

By triangle inequality, the sum of the lengths of any two sides are greater than the length of the third side.

We therefore could set up three inequalities.

x+6>15, x+15>6, 15+6>x

Solving these, we get x>9, x>-9, x<21 i.e. 9 < x < 21.

Answer:

The interest is 450 ⇒ C

Step-by-step explanation:

The formula of the simple interest is I = Prt, where

∵ Birr invested 2500 at 6% simple interest per annum for 3 years

∴ P = 2500

∵ r = 6%

→ Divide it by 100 to change it to decimal

∵ 6% = 6 ÷ 100 = 0.06

∴ r = 0.06

∴ t = 3

→ Substitute them in the formula above

∵ I = 2500 × 0.06 × 3

∴ I = 450

∴ The interest is 450

Answer:

-2

Step-by-step explanation:

First, let's put this in slope-intercept form:

-5y-3x=10

5y = -3x - 10

y = (-3/5)x - 2

The y-intercept is -2.
