If a + b + c = -2 and x + y = 10,<br> what is -9a + 2x - 9b - 9c + 2y?

MaRussiya [10]

38
because since all abc and xy have the same coefficients it makes it easier.
i just made a=-2, b=-4,and c=4 because when added up it equals -2
i also made both x and y =5 becasue when added up it equals 10
so, -9(-2)+2(5)-9(-4)-9(4)+2(5)
18+10+36-36+10=38

Find the equation of a line which passes through (2 4) with a slope of ½

Norma-Jean [14]

Answer:

The equation of the straight line is x - 2y +6 =0

Step-by-step explanation:

<u>Explanation:</u>-

Given a point ( 2, 4) and slope m = $\frac{1}{2}$

The equation of the straight line passing through the point and having slope 'm'

y - y₁ = m ( x - x₁)

y - 4 = $\frac{1}{2}$ ( x - 2)

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

2 y - 8 = x -2

x - 2 y - 2 + 8 =0

x - 2y + 6 =0

The equation of the straight line is x - 2y +6 =0

The Johnson twins were born nine years after their older sister. This year, the product of the three siblings ages is exactly 18

KATRIN_1 [288]

Answer: The age of the twins is 10 years.

Step-by-step explanation:

Suppose the age of older sister be x

Let the age of twins sister be x-9, as they are born after 9 years.

Product of their ages be

$x(x-9)(x-9)\\\\=x(x^2-18x+81)\\\\=x^3-18x^2+81x$

Sum of their ages will be

$x+x-9+x-9\\\\=3x-18$

According to question,

$1861+3x-18=x^3-18x^2+81x\\\\x^3-18x^2+81x-3x+18-1861=0\\\\x^3-18x^2+78x-1843=0\\\\x=19$

So, Age of older sister will be 19 years.

Age of the twins will be

$19-9=10\ years$

Hence, the age of the twins is 10 years.

Slope = 1.75; (10, 16.5)

vazorg [7]

Do you want the equation of the line given the slope and a point it goes through?

y - y1 = m (x - x1)
y - 16.5 = 1.75 (x - 10)
y - 16.5 = 1.75x -17.5
y = 1.75x - 1
