Answer:

Correct choice is D

Step-by-step explanation:

Given the system of two equations:

\left\{\begin{array}{l}4x+y=8\\6x-9y=12\end{array}\right..

Fro mthe first equation

y=8-4x.

Substitute into the second equation 8-4x instead of y:

6x-9(8-4x)=12.

Note that 8-4x=-4x+8, then the second equation will take look

6x-9(-4x+8)=12.

What is the area of a triangle with vertices at (−4, 1) , ​ (−7, 5) ​ , and ​ (0, 1) ​ ?
Mekhanik [1.2K]
Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
 Area of a triangle: A = (1/2)BH

You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units.

A = (1/2)(4)(4)
A = 8

** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)

Can someone please explain The measure of angle A to the nearest tenth of a degree is:
Ratling [72]

Answer:

A =19.5

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin A= opp/ hyp

sin A = 3/9

Take the inverse sin of each side

sin ^-1 sin A = sin ^-1 (3/9)

A =19.47122063

To the nearest  tenth of a degree

A =19.5
