Andreas93 [3]

Answer: 12.800

Step-by-step explanation:

"89.6 by 7' translates to 89.6 divided by 7.

89.6 divided by 7 is equal to 12.8

Check your answer: 12.8 x 7 = 89.6

12.8 is equal to 12.800, it is the answer.

Given points A (1, 2/3), B (x, -4/5), and C (-1/2, 4) determine the value of x such that all three points are collinear
AlladinOne [14]

Answer:

x=\frac{83}{50}

Step-by-step explanation:

we know that

If the three points are collinear

then

m_A_B=m_A_C

we have

A (1, 2/3), B (x, -4/5), and C (-1/2, 4)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope AB

we have

A(1,\frac{2}{3}),B(x,-\frac{4}{5})

substitute in the formula

m_A_B=\frac{-\frac{4}{5}-\frac{2}{3}}{x-1}

m_A_B=\frac{\frac{-12-10}{15}}{x-1}

m_A_B=-\frac{22}{15(x-1)}

step 2

Find the slope AC

we have

A(1,\frac{2}{3}),C(-\frac{1}{2},4)

substitute in the formula

m_A_C=\frac{4-\frac{2}{3}}{-\frac{1}{2}-1}

m_A_C=\frac{\frac{10}{3}}{-\frac{3}{2}}

m_A_C=-\frac{20}{9}

step 3

Equate the slopes

m_A_B=m_A_C

-\frac{22}{15(x-1)}=-\frac{20}{9}

solve for x

15(x-1)20=22(9)

300x-300=198

300x=198+300

300x=498

x=\frac{498}{300}

simplify

x=\frac{83}{50}

Does anyone know how to do this math problem?​
telo118 [61]

Answer:

1,-2

Step-by-step explanation:

Multiply top equation by 3 and bottom by 2

6p+9q=-12

6p+10q=-14

Do bottom - top

(6p+10q)-(6p+9q)= (-14) - (-12)

q = -2

6p + 9(-2)=-12 = 6p=18

6p=18-12=6

p=1
