1) The standard form of a linear equation is written as .

Helen [10]

Answer:

$\displaystyle y=-\frac{a}{b}x+\frac{c}{b}$

Step-by-step explanation:

The equation of the line, expressed in slope-intercept form is:

$y=mx+y_o$

Where m the slope and yo the y-intercept.

Since we are given the line in standard form:

ax+by=c

To find the slope-intercept form, we just solve it for y:

$\boxed{\displaystyle y=-\frac{a}{b}x+\frac{c}{b}}$

Comparing the last equation with the slope-intercept form:

$\displaystyle m=-\frac{a}{b}$

$\displaystyle y_o=\frac{c}{b}$

(1) 4p²q : 10pq²

tiny-mole [99]

Answer: (1) 2p: 5q.

(2) 3:10.

(3) 5:6.

Step-by-step explanation:

To find : Ratio

(1) 4p²q : 10pq²

$=\dfrac{4p^2q}{10pq^2}\\\\=\dfrac{2p^{2-1}}{5q^{2-1}}\\\\=\dfrac{2p}{5q}$

i.e. Simplified ratio of 4p²q : 10pq² is 2p: 5q.

(2) 9 months : 2½ years

1 year = 12 months

$2\dfrac{1}{2}\text{years}=\dfrac{5}{2}\text{years}\\\\=\dfrac{5}{2}\times12=30\text{ months}$

Now, 9 months : 2½ years = $\dfrac{9\text{ months}}{30\text{ months}}=\dfrac{3}{10}$

Hence, Simplified ratio of 9 months : 2½ years is 3:10.

(3) 5 m : 600 cm

1 m = 100 cm

So, 5m = 500 cm

Now, 5 m : 600 cm = $\dfrac{500\ cm}{600\ cm}=\dfrac{5}{6}$

Hence, Simplified ratio of 5 m : 600 cm is 5:6.

Triangle ABC is shown below.

Nastasia [14]

ABC is an isosceles triangle.
Sides : AB = BC
3 x - 7 = 2x
3 x - 2 x - 7 = 2 x - 2 x
x - 7 = 0
x - 7 + 7 = 0 + 7
x = 7
Segment AC:
AC = 3 * 7 - 7 = 21 - 7 = 14
Answer: C ) 14

stellarik [79]

Answer:

the hypothesis is 5or 13

Step-by-step explanation:

let the hypotenuse be y so the first side will be y-1 and the other side will be y-8 repectively and using the pythagoras theorem you solved for the hypotenenuse
