Answer:

d. 690.1 units²

Step-by-step explanation:

1. You can use the Heron's formula to calculate the area of the triangle, which is:

K=\sqrt{s(s-a)(s-b)(s-c)}

Where:

s=\frac{a+b+c}{2}

2. Calculate s:

s=\frac{33+51+42}{2}\\s=63

3. Substitute values into the formula shown above and calculate the area, as following:

K=\sqrt{63(63-33)(63-51)(63-42)}\\K=690.1units^{2}

4. Therefore, the area is 690.1 units².

What is the equation of the line (-2,-3) (4,5)
sleet_krkn [62]
Slope = m = y2-y1/x2-x1
 = 5-(-3)/4-(-2)
m=8/6
m=4/3
so  eq of line we select any of one point . i select (4,5)
y - y1 = m(x-x1)
y- 5 = 4/3 (x-4)
3y -15 = 4x-16
4x-3y = 1

Help. I’m really bad at math. What is the answer?
zhenek [66]
10) (9,-3); m=2

(a) y=2x-11
Plug in the variables that are constant on both the given line and the new one.
y=mx+b

-3=2(9)+b

Do not input b, as the y intercept is relative to the specific line, and not others.

-3=18+b
-3-18=b
-21=b

The y intercept of the new line is -21.

FINAL ANSWER::y=2x-21

(b) y=2x-21
Plug in the variables that are constant on both the given line and the new one.
y=mx+b

-3=2(9)+b

Do not input b, as the y intercept is relative to the specific line, and not others.

-3=18+b
-3-18=b
-21=b

The y intercept of the new line is -21

FINAL ANSWER::y=2x-21
Or equivalent to the original.

Hope this helps you solve the rest. ;)
