Since she answered 90% of her quiz correct, that means if she were to answer 10 questions, 9 would be correct. Lucky for us, 50 is a multiple of 10. If you multiply 10 by 5, you'd get 50. You would also need to multiply 9 by 5 as well. When you do this you'd get

45/50 correct. (divided them to make sure you get .90 if so, I'm right :)

Identify the equation of a line with a slope of -4 and a y-<br> intercept of (0, 2).
Bingel [31]

Step-by-step explanation:

We know that the formula for slope is y=mx+b, with m equaling the slope itself and b equaling the y-intercept. Since the slope is -4, we can safely say that the equation starts off as y=-4x.

The y-intercept is (0,2). This means that the x-coordinate is 0 and the y-coordinate is 2, so the y-intercept is 2. Since 2 is being added, the equation is y=-4x+2

Answer:

y=-4x+2

A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marin
eduard

The location of the treasure on the treasure map is (b) (7.6,8.8)

The ratio is given as:

m : n = 5 : 9

The coordinates of the rock and the tree are:

Rock =(3,2)

Tree = (16,21)

The x and y coordinates of the location of the treasure are:

(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})

So, we have:

(x,y) = (\frac{5 \times 16 + 9 \times 3}{5 + 9},\frac{5 \times 21 + 9 \times 2}{5 + 9})

(x,y) = (\frac{107}{14},\frac{123}{14})

(x,y) = (7.6,8.8)

Hence, the location of the treasure is (b) (7.6,8.8)
