Answer:
<h2>x = -4 and x = -3</h2>
Step-by-step explanation:
Look at the picture.
f(x) = g(x)
f(-4) = 4 and g(-4) = 4 → f(-4) = g(-4)
f(-3) = 8 and g(-3) = 8 → f(-3) = f(-3)
Answer:
15,000cm^3
Step-by-step explanation:
Dividing the solid into 2;
Volume = Volume of A + Volume of B
Volume of Top prism (A) =25cm * 20cm * 10cm
Volume of Top prism (A) = 5000cm^3
Volume of bottom prism B = 20cm * 50 * 10
Volume of bottom prism B = = 10000cm^3
Volume of the figure = 5000 + 10000
Volume of the figure = 15,000cm^3
it is given in the question that
Alpha printing will make 400 brochures for $100. Omega printing will make 1,000 brochures for $100.
For Alpha, cost of 1 brochure is
For Omega,
Cost of 1 brochure is
So choosing Omega printing, you will save
on each brochure .
x + 2 y = 0 is the equation that has the value (1.8, -0.9).
<u>Step-by-step explanation:</u>
The solution is (1.8,-0.9) and the given equations are
x-2y= 4....... 1
4x+5y= 8.....2
6x-5y=15.....3
x+2y=0........4
Substitute the solution in all the equations and equate the resulting values.
∴ Substitute (1.8, -0.9) in equation 1.
1.8-2(-0.9) = 4.
1.8 + 1.8 = 4.
3.6 ≠ 4.
Substitute (1.8, -0.9) in equation 2.
4(1.8)+5(-0.9)=8
7.2-4.5=8.
2.7≠8.
Substitute (1.8, -0.9) in equation 3.
6(1.8)-5(-0.9)=15.
10.8 + 4.5=15
15.3≠15.
Substitute (1.8, -0.9) in equation 4.
1.8+2(-0.9)=0.
1.8-1.8=0.
0=0.
∴x + 2 y = 0 is the equation that has the value (1.8, -0.9).

Answer:
Probability of an event E = p(E) = (number of favorable outcomes of E)/(number of total outcomes in the sample space) This approach is also called theoretical probability. The example of finding the probability of a sum of seven when two dice are tossed is an example of the classical approach.
