A like with slope = 1/2 passes through the points (2,5) and (x,3). What is the value of x?

1 answer:

8 0

Y = mx + b

slope = m = 1/21, so we have

y = 1/2 x + b

The line passes through (2, 5), so we get

5 = 1/2 * 2 + b

5 = 1 + b

b = 4

The equation of the line is

y = 1/2 x + 4

Point (x, 3) has a y-coordinate of 3. We are looking for the x-coordinate.

y = 1/2 x + 4

3 = 1/2 x + 4

-1 = 1/2 x

x = -2

Korvikt [17]

Answer:

First we must learn to dissect a question.

<h3>Explanation:</h3>

Part 1

We can list our facts first:

Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
She needs 13 dozen cookies

She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons

$6.5 \times 1.5 = 9.75 \: teaspoons$

She needs 9.75 teaspoons and 3 teaspoons make a tablespoon

So..

$9.75 \div 3 = 3 r0.75= 3tbsp \: and \: 0.75tsp$

Three equivalent ratios for 6: 54

vodka [1.7K]

Treat it as a fraction where it must stay equal
6/54
with fractions, you can do anything as long as you do it so top and bottom
so 6/54=1/9=2/18=3/27=4/36=5/45 etc

but don't forget to convert back to ratios
so some examples are 1:9
2:18
3:27
4:35
5:45

In which section of the number line is √5?

Ymorist [56]

We know that $\sqrt(4)$ and $\sqrt(9)$ are 2 and 3 respectively. Therefore, $/sqrt(5)$ is between 2 and 3, approximately 2.2.
