Answer:

C. 450

Step-by-step explanation:

Plot the solution area for the system of four inequalities

\left\{\begin{array}{l}4x+y\le 16\\x+y\le 10\\x\ge 0\\y\ge 0\end{array}\right.

You'll get the quadrilateral with vertices at points (0,0), (0,10), (2,8) and (4,0).

The maximum value of the function can be at vertices, so

P=25x+45y\\ \\P(0,0)=25\cdot0+45\cdot 0\\ \\P(0,10)=25\cdot 0+45\cdot 10=450\\ \\P(2,8)=25\cdot 2+45\cdot 8=50+360=410\\ \\P(4,0)=25\cdot 4+45\cdot 0=100

The maximum value of the function is 450 at point (0,10)

Answer:

97.5 miles

Step-by-step explanation:

d = 65t

where d is the distance in miles and t is the time in hours

Therefore, to calculate how many miles the car travels in 1.5 hours, substitute t = 1.5 into the equation:

d = 65 x 1.5 = 97.5 miles

Answer:

Graph C

Step-by-step explanation:

Hi there!

The given linear equations are organized in slope-intercept form: y=mx+b where <em>m</em> is the slope of the line and <em>b</em> is the y-intercept, or the value of y when the line crosses the y-axis.

y = 2x + 4

Here, the <em>b</em> value is 4. Therefore, the y-intercept of this line is 4.

y = -3x - 2

Here, the <em>b</em> value is -2. Therefore, the y-intercept of this line is -2.

To identify the graph that models these equations, we just have to look for the graph where the lines cross the y-axis at 4 and -2.

The only graph that does this is graph C.

I hope this helps!

Red bricks and grey bricks were used to build a decorative wall. The number of red bricks divided by number of grey bricks was 5
azamat
Red bricks : Grey bricks
        5        :            2

Total parts = 5 + 2 = 7

7 parts = 224
-----------------------
Find 1 part:
-----------------------
1 part = 234 ÷ 7
1 part = 32

-----------------------
Find 5 parts:
-----------------------
5 parts = 32 x 5 
5 parts = 160

----------------------------------------------
Answer: 160 Red bricks
