The answer is a.
x^2 -10x+25 = x*x-2*5*x+5*5 => (x-5)(x-5)

We're looking for two numbers that when multiplied, give 25, and when added, give -10.

Factoring 25 leads to 5*5 or -5*-5. The second alternative also fits -5+-5 = -10.

So (x-5)(x-5) is the factorization.

Answer:

4 3/8 miles

Step-by-step explanation:

We are told that: the scale on a map is 1 inch =2 1/2 miles.the distance between two streets on the map is 1 3/4 inches

If 1 inches = 2 1/2 miles

1 3/4 inches =

Cross Multiply

1 3/4 × 2 1/2/1

= 7/4 × 5/2

= 35/8

= 4 3/8 miles

The actual distance between these streets is 4 3/8 miles

D) 4.5 Standard Deviations Above the Mean

All you have to do is add .2 to 6.6 until you reach 7.5

6.8
7.0
7.2
7.4

Then you only need half of .2 to reach 7.5, so it's 4.5 standard deviations above the mean

Please help with question 10

Ray Of Light [21]

Answer:

equation of the line is y=x+1

Step-by-step explanation:

the equation of a line has the form y = mx + b

while m is for the slope and b is for the y-intercept.

you can see from the graph that the line intercepts the y-axis at y=1 this is the b.

you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:

in our case it will be:

$m=\frac{4-2}{3-1} = \frac{2}{2}=1$

then just substitute the values for m and b.
