Answer: x = 12 and y = -8
Explanation:
x + y = 4
4x + 3y = 24
———————
-3(x + y = 4)
4x + 3y = 24
———————-
-3x - 3y = -12
4x + 3y = 24
———————
x = 12
If x = 12
x + y = 4
12 + y = 4
y = -8
Answer:
Step-by-step explanation:
49.4 degrees
Step-by-step explanation:
In Triangle AXY,
We want to determine the angle of elevation from the point is standing to the top of the flagpole, which is the angle at V in the diagram.
In Triangle XVY
|VY|=36 feet
Therefore, the angle of elevation from the point is standing to the top of the flagpole is 49.4 degree to the nearest tenth of a degree.
I think i might of clicked on gthe wrong question sorry
I think the correct answer from the choices listed above is option B. A parabola is a set of points in a plane that are equidistant from <span>a fixed line called the directrix and a fixed point called the focus. The distance is equal all through out from the directrix to the focus.</span>
I don't have my calculator handy. But use an online scientific calc. It will hold those digits. And most calculators tht are good will
Answer:
Equation: y = 2x — 3
Slope: 2
Y-intercept: —3
Step-by-step explanation:
m=∆y/∆x
= —3—(—1)/0—1
= —2/—1
= 2
We Know: y - y0 = m (x—x0)
y — (—3) = 2 (x — 0)
y + 3 = 2x
y = 2x — 3
So
Equation: <em>y </em><em>=</em><em> </em><em>2</em><em>x</em><em> </em><em>—</em><em> </em><em>3</em>
Slope: <em>2</em>
Y-intercept: —3
