Answer:

12.5%

Step-by-step explanation:

To find the percent increase, we will need to find the difference between the two populations.

6300 - 5600 = 700 people.

Now, divide this increase by the original population:

$\frac{700}{5600} = 0.125$

Multiply this by 100 to get your percent of increase:

0.125 × 100 = 12.5%

A line m is perpendicular to an angle bisector of ∠A. The sides of ∠A intersect this line m at points M and N. Prove that △AMN i

Ray Of Light [21]

Answer:

Step-by-step explanation:

Given: A line m is perpendicular to the angle bisector of ∠A. We call this

intersecting point as D. Hence, in figure ∠ADM=∠ADN =90°.

AD is angle bisector of ∠A. Hence, ∠MAD=∠NAD.

To Prove: ΔAMN is an isosceles triangle. i.e any two sides in ΔAMN are

equal.

Solution: Now, In ΔADM and ΔADN

∠MAD=∠NAD ...(1) (∵Given)

AD=AD ...(2) (∵common side)

∠ADM=∠ADN ...(3) (∵Given)

Hence, from equation (1),(2),(3) ΔADM ≅ ΔADN

( ∵ ASA congruence rule)

⇒ AM=AN

Now, In Δ AMN

AM=AN (∵ Proved)

Hence, ΔAMN is an isosceles triangle.

A linear function has the same y-PLEASE PLEASE HELP!!!!intercept as x+2y=10 and it’s graph contains the point (9,7) find the slo

Anastasy [175]

Answer:

I think it is 2/9 or 0.22

Step-by-step explanation:

You know they have the same y intercept, so first you should find the y intercept of the givern equation.

x+2y = 10

2y = -x + 10 [subtract x]

y = -.5x + 5 [divide by 2]

Now you have the equation in graph form, and know the y intercept is 5.

If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)

now that you have two points, you can use slope formula.

(y2 - y1)/(x2-x1)

(change in y)/(change in x)

so,

(7-5)/(9-0) = 2/9 = 0.2

someone please correct me if i'm wrong:)

NEED THIS ASAPWrite the standard form of the equation of each line given the slope and y-intercept

Mama L [17]

Note:

Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.

Question 2

Answer:

The equation in the standard form is:

2/3x + y = -4

Please also check the attached graph.

Step-by-step explanation:

We know that the equation in the standard form is

Ax + By = C

where x and y are variables and A, B and C are constants

Given

Slope m = -2/3

y-intercept = -4

To determine

Write the equation in the standard form

We know that the slope-intercept form of the line equation

$y = mx+b$

where

m is the slope

b is the y-intercept

In our case:

Slope m = -2/3

y-intercept = -4

substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation

y = mx+b

y = -2/3x + (-4)

y = -2/3x - 4

Writing the equation in the standard form

2/3x + y = -4

Therefore, the equation in the standard form is:

2/3x + y = -4
