Answer:
Yo, check this out, S=a×a=a², the formula to find the area of a square.
Step-by-step explanation:
S=49 yd²
S=a×a=a²
a²=49===> √a²=√49 yd²===> |a|=7 yd===> a=7, –7
but be aware that we ain't got no squares with a negative length, so the answer is
7 yd
f(-2) means the x value is -2 and you need to find the y value at that point.
At x = -2 the line crosses the y axis at y = 2
f(-2) = 2

Answer:
93
Step-by-step explanation:
Line EJ is a straight line, with Line DC cutting through it. So 180 = Angle DCJ + Angle DCE. So Angle DCE = 48. Triangles are equal to 180°. So 180 = ? +39 +48. So ? = 93
<h3>Option A</h3><h3>3x - y = -5 is the equation of the line with a slope 3 and y intercept 5</h3>
<em><u>Solution:</u></em>
<em><u>The slope intercept form of equation is given as:</u></em>
y = mx + c ------ eqn 1
Where,
m is the slope of line
c is the y intercept
From given,
slope = m = 3
y intercept = c = 5
<em><u>Substitute m = 3 and c = 5 in eqn 1</u></em>
y = 3x + 5
3x - y = -5
Thus the equation of line is found
