Answer

-4x - 2

Explanation

To get the function needed, first calculate the slope of the graph.

slope = (change in y) / (change in x)

= (2 - -2)/(-1 - 0)

= 4/-1

= -4

Now use one of the point (-1, 2) in the graph and a general point (x,y) to find the function.

-4 = (y - 2)/(x - -1)

-4(x + 1) = y - 2

-4x - 4 = y - 2

y = -4x - 4 + 2

= -4x - 2

∴ f(x) = -4x - 2

2. angle ABE = angle MNP Write another valid congruency statement:

Free_Kalibri [48]

Given:

$\Delta ABE\cong \Delta MNP$

To find:

The congruent angles and sides, then find the another valid congruency statement.

Solution:

We have,

$\Delta ABE\cong \Delta MNP$

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

Using CPCTC, we get

Angles:

$\angle A\cong \angle M$

$\angle B\cong \angle N$

$\angle E\cong \angle P$

Sides:

$AB\cong MN$

$BE\cong NP$

$AE\cong MP$

The another congruent statement is $\Delta BEA\cong \Delta NPM$ .

Therefore, the required table is

Angles Sides

$\angle A\cong \angle M$ $AB\cong MN$

$\angle B\cong \angle N$ $BE\cong NP$

$\angle E\cong \angle P$ $AE\cong MP$

The another congruent statement is $\Delta BEA\cong \Delta NPM$ .

Chester needs 2 feet of ribbon for an art project, but his ruler only measures in centimeters. There are 12 inches in 1 foot and

Arte-miy333 [17]

Answer:

see the explanation

Step-by-step explanation:

step 1

Convert feet to inches

we know that

$1\ ft=12\ in$

To convert feet to inches, multiply by 12

$2\ ft=2(12)=24\ in$

step 2

Convert inches to centimeters

we know that

$1\ in=2.54\ cm$

To convert inches to centimeters multiply by 2.54

$24\ in=24(2.54)=60.96\ cm$

therefore

Chester should have multiplied the measurement in inches by 2.54 instead of dividing by 2.54

Verizon [17]

D) 1 1/4

She needs 1/4 to make 1 batch so multiply that by 5 (or add 1/4, 5 times) 5 * 1/4 = 5/4 = 1 1/4
