The slope is 5/2 and connect the two points in a triangle form
ozzi3 years ago
4 0

Answer:

y=7/2x+2  <---- slope intercept form

Step-by-step explanation:

I can't draw the slope triangle but I can give you the equation.

So use the 2 given points, (2,9) and (4,16)

find the slope by using the slope formula

y2-y1/x2-x1

enter the points in

16-9/4-2=7/2

slope=7/2

y=7/2x+b

enter one of the points in (2,9)

9=7+b

b=2

y=7/2x+2

A stick has a length of $5$ units. The stick is then broken at two points, chosen at random. What is the probability that all th
Zinaida [17]

Answer:

4/25 = 0.16

Step-by-step explanation:

The shortest stick must be between 0 and 5/3.  The probability that it is longer than 1 is therefore:

(5/3 − 1) / (5/3 − 0)

(2/3) / (5/3)

2/5

So the probability that both of the shortest sticks are longer than 1 is (2/5)² = 4/25.

Which is greater, 1 5/8 or 1 2/3 how can you be sure?
krek1111 [17]
Lets get these into improper fractions. 

1*8 + 5 = 8+5 = 13

13/8 

1*3 + 2 = 3+2 = 5

5/3

Now divide

13/8 = 1.625
5/3 = 1.6666

1  2/3 is larger

Solve the following equations.<br> √3 ⋅ 3^3x = 9
GREYUIT [131]

Answer:

The solution is x = 0.5

Step-by-step explanation:

We need to write everything as a power of 3.

We know that:

\sqrt{a} = a^{0.5}

So

\sqrt{3} = 3^{0.5}

And

9 = 3^{2}

This following property is also important:

\frac{a^{b}}{a^{c}} = a^{b-c}

To solve, the first step is putting everything with the variable x on one side and everything without the variable x on the other side

\sqrt{3}.3^{3x} = 9

3^{0.5}.3^{3x} = 3^{2}

3^{3x} = \frac{3^{2}}{3^{0.5}}

3^{3x} = 3^{2-0.5}

3^{3x} = 3^{1.5}

This means that:

3x = 1.5

x = \frac{1.5}{3}

x = 0.5

If ∠a = 90°, find the measures of ∠b, ∠c and ∠d.
nydimaria [60]

Answer:

m∠b = 35°

m∠c = 145°

m∠ d = 35°

Step-by-step explanation:

To find m∠b, we use Definition of Supplementary Angles:

180 - (90 + 55) = 35°

To find m∠c, we also use Definition of Supplementary Angles:

180 - 35 = 145°

To find m∠d, we use Vertical Angles Theorem:

m∠b = m∠d = 35°
