Answer:
8. 20.8 units
9. isosceles
Step-by-step explanation:
8.The vertical altitude line divides the triangle into two congruent right triangles. Each has a horizontal leg of 4 units, and a vertical leg of 5 units. (You can find these lengths by subtracting coordinates, or by counting grid squares.)
slant sides
The hpotenuses of these right triangles are the short sides (PR, QR) of the larger triangle PQR. We can find their length using the Pythagorean theorem. Defining S as point (-2, -1), we have ...
PS² +SR² = PR² . . . . . . . . . . . . the Pythagorean theorem relation
4² +5² = PR² = 16 +25 = 41 . . . with numbers filled in
PR = √41 . . . . . . . . . . . . . . take the square root
PR ≈ 6.4 . . . . . . . . . . . round to tenths
horizontal side
The length of side PQ is 8 units, found by subtracting x coordinates ((2 -(-6)) = 8), by counting grid squares, or by doubling the length of PS (2(4) = 8).
perimeter
The perimeter of the triangle is the sum of its side lengths:
perimter = PR +QR +PQ = 6.4 +6.4 +8 = 20.8
The perimter of triangle PQR is 20.8 units.
__
9.Sides PR and QR are congruent, so the triangle is isosceles.
_____
Additional comment
A triangle whose vertices are integer grid coordinates cannot be equilateral.

Solve the following systems using the elimination method.
4x + 7y = 19
2x - y = -13
Answers
Answer: x = -4, y = 5
Step-by-step explanation:
[tex]$$Solve the following system: \\$\left\{\begin{array}{ll}7 y+4 x=19 & \text { (equation 1) } \\ -y+2 x=-13\end{array} \quad\right.$ (equation 2)\\\\Subtract $\frac{1}{2} \times($ equation 1) from equation 2 :\\$\left\{\begin{array}{l}4 x+7 y=19 \ \ \ \ (\text{equation 1}) \\ 0 x-\frac{9 y}{2}=-\frac{45}{2}\end{array}\right.$ (equation 2)\\\\Multiply equation 2 by $-\frac{2}{9}$ :\\[/tex]
[tex]\begin{cases}4 x+7 y=19 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Subtract $7 \times($ equation 2) from equation 1:\\$\begin{cases}4 x+0 y=-16 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2)\\ }\end{cases}$\\\\Divide equation 1 by 4 :\\$\begin{cases}x+0 y=-4 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Answer:\\$$\left\{\begin{array}{l}x=-4 \\y=5\end{array}\right.$$[/tex]
Step-by-Step Explanation:
=> 4x + 7y = 19 (Eq. 1)
=> 2x - y = -13 (Eq. 2)
We can multiply Eq. 2 by 7 in order to make the coefficients of ‘y’ same in both the equations thus being able to eliminate ‘y’ and find ‘x’
Therefore,
(2x - y = -13) * 7
=> 14x - 7y = -91 (Eq. 3)
On Adding Eq. 1 and 3, we get :-
18x = -72 (‘y’ gets Eliminated)
x = -72/18
=> x = -4
Therefore, x = -4
Substitute value of ‘x’ in Eq. 2 :-
2x - y = -13
2(-4) - y = -13
-8 - y = -13
-y = -13 + 8
-y = -5
=> y = 5
Therefore, y = 5

Three time the quotient of a number and 2 increased by 5 is at most -12.1/10x+9/10=1/10(BLANK)
Answers
Answer:
x=-8
Step-by-step explanation:
1 Simplify 1/10x to x/10.
x/10 + 9/10 = 1/10
2 Join the denominators.
x+9/10 = 1/10
3 Multiply both sides by 10.
x+9 = 1/10×10
4 Cancel 10.
x+9=1
5 Subtract 9 from both sides.
x=1-9
6 Simplify 1-9 to -8.
x=-8

Answers
Answer:
23.5 cm^2
Step-by-step explanation:
First calculate the "rectangle" with the half-circle filled in
9*3 = 27
Then calculate the half-circle using the formula for the area of a circle [tex]\pi r^{2}[/tex], then dividing it by half
3.14 * 1.5 * 1.5 / 2 = 3.5325
Subtract the area of the half-circle from the area of the rectangle
27-3.5325
= 23.4675
= 23.5 (cor. to the nearest half unit)
