If you have 3 sticks of length 2 cm, 3 cm and 5 cm. What kind of triangle these sticks would form? Justify your answer.

Algebra 1 Honors

Paul [167]

Answer:

19200

brainliest if correct

Explanation

12% of 120,000 = 14400

14400x7 = 100800

120,000 - 100800 = 19200

A 48-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece

ohaa [14]

Answer:

6 inch, 12 inch, 30 inch

Step-by-step explanation:

x + 2x + 5x = 48

8x = 48

x = 6

6 x 2 = 12

6 x 5 = 30

The coordinate plane below represents a city.

alex41 [277]

Answer:

Part A) The system of inequalities is

$x\geq2$ and $y\geq2$

Part B) In the procedure

Part C) The schools that Natalie is allowed to attend are A,B and D

Step-by-step explanation:

Part A: Using the graph above, create a system of inequalities that only contain points C and F in the overlapping shaded regions

we have

Points C(2,2), F(3,4)

The system of inequalities could be

$x\geq2$ -----> inequality A

The solution of the inequality A is the shaded area at the right of the solid line x=2

$y\geq2$ -----> inequality B

The solution of the inequality B is the shaded area above of the solid line y=2

see the attached figure N 1

Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

Verify point C

C(2,2)

Inequality A

$x\geq2$ -----> $2\geq2$ ----> is true

Inequality B

$y\geq2$ ------> $2\geq2$ ----> is true

therefore

Point C is a solution of the system of inequalities

Verify point D

F(3,4)

Inequality A

$x\geq2$ -----> $3\geq2$ ----> is true

Inequality B

$y\geq2$ ------> $4\geq2$ ----> is true

therefore

Point D is a solution of the system of inequalities

Part C: Natalie can only attend a school in her designated zone. Natalie's zone is defined by y < −2x + 2. Explain how you can identify the schools that Natalie is allowed to attend.

we have

$y < -2x+2$

The solution of the inequality is the shaded area below the dotted line $y=-2x+2$

The y-intercept of the dotted line is the point (0,2)

The x-intercept of the dotted line is the point (1,0)

To graph the inequality, plot the intercepts and shade the area below the dotted line

see the attached figure N 2

therefore

The schools that Natalie is allowed to attend are A,B and D

If two points on line l above have coordinates (0, A) and (2, −3), and the slope of the line is A, then what is the value of A?

Anna35 [415]

ANSWER:

If two points on line l above have coordinates (0, A) and (2, −3), then the value of A is -1

SOLUTION:

Given, two points on line l have coordinates (0, A) and (2, −3),

And the slope of the line is A,

We need to find a value.

We know that, slope of a line on which (x1, y1) and (x2, y2) are two points is given by

$\mathrm{m}=\frac{y_{2}-y_{1}}{\mathrm{x}_{2}-\mathrm{x}_{1}}$

Here,in our problem,

$\mathrm{m}=\mathrm{A}, \mathrm{x}_{2}=2, \mathrm{x}_{1}=0, \mathrm{y}_{2}=-3 \text { and } \mathrm{y}_{1}=\mathrm{A}$

now, substitute the values in formula we get

$\begin{array}{l}{A=\frac{-3-A}{2-0}} \\\\ {A=\frac{-3-A}{2}}\end{array}$

2A = -3 –A

2A+ A = -3

3A = -3

A = -1

Hence, the value of A is -1.
