3x+7-5x=8
-2x+7=8
-2x=1
X=-1/2
y=3(-1/2)+7
y=-1.5+7
y=5.5
38.1 seconds I believe simply divide 4m/s into 152.4 m and you will have 38.1 seconds
Answer:1=70 2=65 3=95
Step-by-step explanation:
Angles in a triangle add up to 180°
180-45=135-65=70
1=70°
Angles on a straight line add up to 180°
180-45=135-70=65
2=65°
Angles in a triangle add up to 180°
180-65=115-20=95
3=95°
Answer:
Step-by-step explanation:
we have that
![f(x) = x^2 + x - 9](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%20%2B%20x%20-%209)
Using a graph tool
see the attached figure
The function represent a vertical parabola that open up
the vertex is a minimum-------> is the point (-0.5, -9.3)
The x-intercepts are the points when the y coordinate is equal to zero
The x-intercepts are the points (-3.5, 0) and (2.5, 0)
so
the function cross the negative x-axis at point
therefore, the answer is
(-4, 0) and (-3, 0)
