Please help problems below!!!

Delvig [45]

Answer:

#16 has the greatest y - intercept,

Step-by-step explanation:

the y - intercept is the number that comes after x in y = ?x + ?

The equation is y = mx + b, where m is the slope and b is the y - intercept.

#13 has a y - intercept of 5, #14 has 0, #15 is 2, and #16 is 6

The y - intercept is the value of y when x is 0, or where the line is on the y -axis

I NEED ANSWER ASAP! I WILL GIVE BRAINELIEST!!!!!! Construct a right triangle whose legs are in the ratio 3:4. What are the ratio

Gala2k [10]

Answer:

3 : 5, 4: 5

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

Therefore, lengths of the legs of right triangle would be 3x and 4x

By Pythagoras Theorem:

${hyp}^{2} = {(3x)}^{2} + {(4x)}^{2} \\ = 9 {x}^{2} + 16 {x}^{2} \\ = 25 {x}^{2} \\ hyp = \sqrt{25 {x}^{2} } \\ hyp = 5x \\ \\ ratios \: of each \: leg \: to \: the \: hypotenuse \\ \frac{3x}{5x} = 3 : 5 \\ \\ \frac{4x}{5x} = 4 : 5$
