Answer:

Finding slope: y2-y1/x2-x1

3-9/1+2

=-6/2

Divide 2 from both

=-3/1 or -3

Slope= -3

Finding y-intercept= y=mx+b

Choose any point on the line to plug in the x and the y then plug in the slope.

I choose (1,3)

3=-3×1+b

3=-3+b

Add 3 to both sides

6=b

Y-intercept=6

Equation: y=-3x+6

Express 18 as a product of its factors?

Dimas [21]

Answer:

18= 2 x 3 x 3

Step-by-step explanation:

Basically, we branch out 18 into its prime factors. So, the prime factorization of 18 is 18= 2 × 3 × 3. A factor tree is not unique for a given number. Instead of expressing 18 as 2 × 9, we can express 18 as 3 × 6.

Christine's middle school has a total of 900 students and 45 teachers . The local high school has 110 teachers & a student-t

qaws [65]

Answer:

2,200 students

Step-by-step explanation:

To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.

$\frac{students}{teachers}= \frac{900}{45}=\frac{x}{110}$

Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.

900(110) = 45(x)

99,000=45x

2,200 = x

Simplify. final answer should be written in standard form (a+b)(3a-b)(2a+7b)

algol13

we have

(a+b)(3a-b)(2a+7b)

step 1

Solve

apply distributive property

(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2

step 2

Multiply (3a^2-4ab-b^2) by (2a+7b)

6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3
