Patricia is making two sizes of hamburgers: 0.5-pound andd 0.25-pound. How many of each size of hamburger could she make with 3.
mixas84 [53]

Answer:

She could make 5 of each type.

Step-by-step explanation:

If x is the number of 0.5 pound hamburgers and y is the number of 0.25 pound hamburgers:

0.5x + 0.25y = 3.75

Divide through by 0.25:

2x + y = 15

Some whole numbers which fit this relation  are x = 5 and y = 5.

What are the four points of intersection between 4x^2 + y^2 - 4y - 32 = 0 and x^2 - y - 7 = 0 ? Solve algebraically
tensa zangetsu [6.8K]
Remember (a²-b²)=(a-b)(a+b)

solve for  a single variable
solve for y in 2nd

add y to both sides
x²-7=y
sub (x²-7) for y in other equaiton

4x²+(x²-7)²-4(x²-7)-32=0
expand
4x²+x⁴-14x²+49-4x²+28-32=0
x⁴-14x²+45=0
factor
(x²-9)(x²-5)=0
(x-3)(x+3)(x-√5)(x+√5)=0
set each to zero

x-3=0
x=3

x+3=0
x=-3

x-√5=0
x=√5

x+√5=0
x=-√5


sub back to find y

(x²-7)=y

for x=3
9-7=2
(3,2)

for x=-3
9-7=2
(-3,2)

for √5
5-7=-2
(√5,-2)

for -√5
5-7=-2
(-√5,-2)


the intersection points are

(3,2)
(-3,2)
(√5,-2)
(-√5,-2)

Find the hypotenuse of a right triangle if side a=3 and side b=4​
Slav-nsk [51]

Answer:

5 units

Step-by-step explanation:

By Pythagoras theorem:

(hypotenuse)^2 = a^2+ b^2\\\therefore hypotenuse = \sqrt{a^2+ b^2} \\\therefore hypotenuse = \sqrt{3^2+ 4^2} \\\therefore hypotenuse = \sqrt{9+ 16} \\\therefore hypotenuse = \sqrt{25} \\\therefore hypotenuse = 5\: units
