Answer:
4.45 or 4 so b
Step-by-step explanation:
Sum of two sides of the triangle should be more than 3d side.
n<20+5,
n<25
Third side should be more than difference of two other sides.
n> 20-15
n>5
So, n should be
5<n<25.
C
Because the graph of the line is y = 2x + 2
The graph is shaded above the line, so we want y values above the line and since it is shaded in (red and not dashed), we want the values above and on the line (aka greater than or equal to SIGN)
Answer:
Solution of the system of equations: (1, 1)
x = 1, y = 1
Explanation:
Given the below system of equations;

Note that the slope-intercept form of the equation of a line is given as;

where m = slope of the line
b = y-intercept of the line
Comparing the given system of equations with the slope-intercept equation, we can see that, for the 1st equation (y = -3x + 4), the slope(m) = -3 and y-intercept(b) = 4 and for the 2nd equation, slope(m) = 3 and y-intercept(b) = -2.
Knowing the above information, let's go ahead and graph the system of equations;
From the above graph, the point of intersection of the two lines (1, 1) is the solution of the system of equation.
Answer:
45v+36
Step-by-step explanation:
9•5v= 45v
9•4= 36
45v+36
