Write the equation of the line passing through the points (-4,5) and (4,1). Show all of your work.
[4 points)
please someone help me with this

Answers

Answer 1

First, find the slope using the equation, y2 - y1 / x2 - x1

1-5 / 4 - - 4 = -4/8 =  -1/2

plug this into slope intercept form

y = -1/2x + b

Next use one of the points to find b using point-slope form. I will use (4,1)

y - y1 = m ( x - x1)

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

y -1 = -1/2x + 2

+1                  +1

y = -1/2x + 3 is your equation

There are 96 girls and 72 boys who want to participate in 6th grade intramurals .If each team has the same number of girls and the same number of boys,How many boys and girls will be on each team?

Answers

Answer:

by taking Hcf of 96 and 72 we get 4 so each team have 4

'24' teams can be made with each team having 4 girls and 3 boys.

Given that,

No. of girls = 96

No. of boys = 72

Since the number of teams is not given, we will find by finding out the GCF(Greatest Common factor) of 96 and 72.

96 = 2 * 2 * 2 * 2 * 2 * 3

72 = 2 * 2 * 2 * 3 * 3

GCF = 2 * 2 * 2 * 3 = 24

Thus, a maximum of 24 teams can be formed. The number of girls and boys in each of these teams would be:

No. of girls in each team = Total girls/no. of teams

= 96/24

= 4 girls

No. of boys in each team = Total boys/no. of teams

= 72/24

= 3 boys

Thus, each team will have 4 girls and 3 boys.

Katie invested a total of ​$4000​, part at 2​% simple interest and part at 3​% simple interest. At the end of 1​ year, the investments had earned ​$90 interest. How much was invested at each​ rate?

Answers

Answer:

$3000

$1000

Step-by-step explanation:

the formula for simple interest = principal x time x interest rate

let the amount invested in the 2% investment be a

let the amount invested in the 3% investment be (4000 - a)

(a x 0.02 x 1) + ([4000 - a] x 0.03 x 1) = $90

0.02a + 120 - 0.03a = 90

Collect like terms and solve for a

0.01a = 30

a = $3000

The amount invested in the 3% investment be (4000 - a)  = $4000 - $3000 = $1000

In the figure, AC is perpendicular to DB.

Which of the following statements is TRUE?​

Answers

Answer:

B. Angle 5 and Angle 6 are complementary

Step-by-step explanation:

Definition of complementary- either of two angles who sum is 90°

As, Line AC and Line DB are perpendicular, Angle DO(the middle point)C is equal to 90°.

Angle DOC = 90°

Angle DOC = Angle 6 + Angle 5

Therefore, Angle 6 + Angle 5 are equal to 90°, so they are complementary.
