Answer:

B. x = 7, y = 4√2

Step-by-step explanation:

Drop a vertical from the upper left corner

This creates a rectangle and a 45-45-90 triangle

The bottom of the rectangle is 3

The legs of the triangle are 4

Therefor

x = 4 + 3

x = 7

For a 45-45-90 triangle

the hypotenuse = leg * √2

y = 4√2

Answer:

y = 2(x-3)

Step-by-step explanation:

This is because Gavin representing "x" loses 3 marbles, which is shown by the -3 in the parenthesis, is half of what Cindy has, or as the problem says "Cindy has double the marbles that Gavin has." These two together result in y=2(x-3)

Make a conjecture of what the x-intercepts of the function<br> f(x) = (2x - 1)(x + 3) will be.

Answer:

x=-3,x1/2

Step-by-step explanation:

f(x)=(2x-1)(x+3)

TI find x intercept/zero substitute

f(x)=0

0=(2x-1)x(x+3)

swap the sides of the equation

(2x-1)x(x+3)=0

when the product of factors equals 0,at least one factor is zero

2x-1=0

x+3=0

solve the equation for x

x=1/2

x+3=0

solve the equation of x

x=-3

The equation has two solution

x=-3

x=1/2

A rectangular picture frame measures 18" x 22". If 1 inch equals 2.54 cm, the dimensions of the picture frame in centimeters wou

Kisachek [45]

It would be 45.72 cm by 55.88 cm because you have to multiply each dimension by 2.54 to get the exact measurement in centimeters.
