Answer:

b = 3

Step-by-step explanation:

Use the table to find the slope and y-intercept

Find the slope:

m = (6 - 4)/(3 - 1) = 2/2 = 1

Find b using the pair (1, 4):

4 = 1*1 + b
b = 4 - 1
b = 3

The line is:

y = x + 3

The y-intercept is 3

How do you solve this equation? 2 1/2 - 3/4

borishaifa [10]

Answer:

1 3/4

Step-by-step explanation:

you have to convert the mixed numbers into improper fractions first

2 1/2 turns into 5/2

then you make the denominators the same

5/2 turn into 10/4

then you subtract

10/4 - 3/4 = 7/4

then you turn it into a mixed number

7/4 turns into 1 3/4

Catherine is at the Supermarket, and knows that she is 50 yards from her school. The map on her phone shows that the school is \

Lubov Fominskaja [6]

Answer:

Answer: b 200 yards

Step-by-step explanation:

Scaling

Real magnitudes can be scaled up or down to adapt to the size of a sheet of paper or the screen of a computer or phone.

Catherine knows she is 50 yards from the school and it's shown as a distance of 3/4 inch on her phone map.

We can calculate the scaling factor from the real distance to the map distance by dividing:

$\displaystyle \frac{50}{\frac{3}{4}}=\frac{200}{3}$

Now she sees that she's 3 inches from home on the same map. This is equivalent to a real distance of:

$\displaystyle 3\cdot \frac{200}{3}=200$

Catherine is 200 yards from her home.

Answer: b 200 yards

370 weeks can also equal 7.09589041, if you need to simplify that just say 7 years

This is easy but i need help on it

Murljashka [212]

A is a function

To represent a function each value from the input (x ) can only map to exactly one value in the output (y)

In B

x = 3 → y = 10/ 30 ← 2 values of y

In C

x = - 5 → y = 2/ 3 ← 2 values of y

x = - 10 → y = 4/ 5 ← 2 values of y

In D

x = 20 → y = 25/ 35 ← 2 values of y

A is the only table where each value of x maps to exactly one value in y
