Answer:
Step-by-step explanation:2(4x+y=10)
3x-2y=13
distribute the 2 to each number and then cancel out -2y and 2y and solve for x, then plug in x and solve for y using one of the equations
Y+4=2/3(x+3)
(-3,-4)(3,0)
1.find the slope
m=y2-y1/x2-x1
m=0-(-4)/3-(-3)
m=4/6
m=2/3
y-(-4)=2/3(x-(-3))
y+4=2/3(x+3) point-slope form
Answer: We have c = 3 and d = -2
Step-by-step explanation:
We want to solve the equation:
6200.07 = 6.2x10^c + 7x10^d
First, we can separate the left number into two pieces:
6200.07 = 6200 + 0.07 = 6.2x10^c + 7x10^d
Now we can solve it as:
6200 = 6.2x10^c
6200/6.2 = 10^c
1000 = 10^c
now we can use that if y = a^x, then ln(y)/ln(a) = x
here we have:
c = ln(1000)/ln(10) = 3
and
0.07 = 7x10^d
0.07/7 = 10^d
0.01 = 10^d
d = ln(0.01)/ln(10) = -2
Answer:
273.2
Step-by-step explanation:
Surface area of the pyramid=Area of square+4*area of triangle
Surface area of the pyramid=10^2+2*(8.66)*10
Surface area of the pyramid=100+173.2=273.2
Answer:
The Choice N#1 will give more pizza for your money
Step-by-step explanation:
step 1
Find the area of one slice Choice #1
The area of the circle is equal to

we have
----> the radius is half the diameter
assume

The area of one slice is equal to

substitute


Divide the cost by the area

step 2
Find the area of the entire personal pizza Choice # 2
The area of the circle is equal to

we have
----> the radius is half the diameter
assume

substitute


Divide the cost by the area

therefore
The Choice N#1 will give more pizza for your money
