Solve the simultaneous equations
y – x = 3
y = 7x
Answer:
x=1/2, y=3 1/2
Step-by-step explanation:
substitute y=7x into y-x=3
7x - x = 3
6x = 3
x=1/2
y=7(1/2)
y=3 1/2
f(x) = 2x2 + 12x + 1
Determine the vertex !
Answer:
(-3, -17)
Step-by-step explanation:
The best way to find the vertex is to rewrite the given quadratic in vertex form: y - k = a(x - h)^2.
The given quadratic is f(x) = 2x2 + 12x + 1. We will focus on the first two terms and "complete the square." f(x) = 2x2 + 12x + 1 can be rewritten as
f(x) = 2(x^2 + 6x) + 1, which, after completing the square, is
f(x) = 2(x^2 + 6x + 9 - 9) + 1, or
f(x) = 2( (x + 3)^2 - 9 ) + 1, or
f(x) = 2(x + 3)^2 - 17
Comparing this to
f(x) = a(x - h)^2 + k, we see that the vertex is located at (h, k): (-3, -17)

Jake makes nine loads of all the bread. He uses 30 grams of olives in each loaf. He started with 1 kg of olives how many grams of olives does Jake have left
9514 1404 393
Answer:
730 grams
Step-by-step explanation:
1 kg is 1000 g.
The amount remaining is ...
1000 g - 9(30 g) = (1000 -270) g = 730 g
Jake has 730 grams of olives left.

Let's put it all together now.
n + 5 = 22
Done!
Answer:
Step-by-step explanation:
First, let's call "a number": n
Then, "five more than" means to add 5 to what follows or:
n+5=22

A hexagon is inscribed in a circle As see in the picture.Find the length of an arc between consecutive vertices. Round to the nearest hundred
Need help homework
Answer:
The length of the arc between consecutive vertices is:
[tex]S=8.38\: in[/tex]
Step-by-step explanation:
The angle between consecutive vertices is 60°, it is because it forms an equilateral triangle.
Now, the length arc is defined as:
[tex]S=R\theta[/tex]
Where:
R is the radius (R = 8 in)θ is the angle of the arcWe see the angle is in grades, but we need to convert it to radians.
[tex]\theta=\frac{60^{\circ}}{360^{\circ}}(2\pi)[/tex]
[tex]\theta=1.05\: rad[/tex]
Finally, the length of the arc between consecutive vertices will be:
[tex]S=8*1.05[/tex]
[tex]S=8.38\: in[/tex]
I hope it helps you!
How many solutions does this equation have?
–2 + 2s = –3s + 8
Answer:
Step-by-step explanation:
-2 + 2s = - 3s + 8
-2 - 8 = - 3s - 2s
-10 = - 5s
-10/-5 = s
2 = s
Answer:
2
Step-by-step explanation:
-2+2s=-3s+8
-2+2s-(-3s)=8
-2+2s+3s=8
-2+5s=8
5s=8-(-2)
5s=8+2
5s=10
s=10/5
s=2
Find the perimeter and area of this figure. Plz show work
Answer:
perimeter = 30.56 units
Step-by-step explanation:
perimeter of full circle = 2(4)(3.14) = 25.12
perimeter of semi circle = (25.12)(0.5) = 12.56
perimeter = 12.56 + 10 + 8 = 30.56

Answer:
See below.
Step-by-step explanation:
Part AFunction A.
x y
3 3
5 7
6 9
slope = (9 - 7)/(6 - 5) = 2
y = 2x + b
3 = 2(3) + b
b = -3
y = 2x - 3
Function A is y = 2x - 3
Function B.
(0, 3)
(-5, 0)
slope = (0 - 3)/(-5 - 0) = -3/-5 = 3/5
b = 3
Function B is y = 3/5 x + 3

Answer:
Step-by-step explanation:

the formula for the volume of a cone is V=1/3hπr²
549.5 = 1/3(21)(3.14)(x)^2
549.5 = 7(3.14)(x)^2
549.5 = 21.98(x)^2
549.5 = 21.98(x)^2
divide by 21.98 on both sides
25 = (x)^2
sqrt 25 = sqrt x^2
5 = x

the formula for the volume of a sphere is V=4/3πr^3
v=4/3(3.14)9^3
v=4/3(3.14)729
v=(4.186)729
v=3052.08
14.
the formula for the volume of a sphere is V=4/3πr^3
523=4/3(3.14)r^3
523=4/3(3.14)r^3
523=(4.186)r^3
divide by 4.186 on both sides
124.92=r^3
cube root on both sides
4.998=r
round
5=r
