Mathematics

alina1380 [7]2 years ago
8 0

Answer:

x=11

Step-by-step explanation:

Notice that the first diagram is similar with the second diagram with ratio 1:2

Ex: Side length of JK is 6 and NP being 12, 6:12→1:2

You can conclude that x:22 needs to follow the ratio of 1:2

Thus, x=11

Write in slope-intercept form an equation of the line that passes through the points (−1,12) and (1,2).
zzz [600]

Answer:

y=-5x+7

Step-by-step explanation:

step 1

Find the slope

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

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

we have

the points (−1,12) and (1,2)

substitute

m=\frac{2-12}{1+1}

m=\frac{-10}{2}

m=-5

step 2

we know that

The equation of the line in slope intercept form is equl to

y=mx+b

where

m is the slope

b is the y-intercept

we have

m=-5

point\ (1,2)

substitute in the linear equation and solve for b

2=-5(1)+b

b=2+5=7

therefore

y=-5x+7

Adam leaves school at 4 p.m. and walks home at a constant pace of three mph. Amy leaves school thirty minutes later, but she bro
madam [21]

Answer:

10 minutes

Step-by-step explanation:

Adam- 3 mph = 20 minutes a mile

Amy- 12 mph = 5 minutes a mile

Adam left 30 minutes prior to Amy so he is a mile and a half ahead before amy even starts.

30 minutes = 1.5 miles (Adam)

7.5 minutes = 1.5 miles (Amy)

but with this being said you have to continue to add time and miles to Adam because he's now gone an extra 7.5 minutes too.

45 minutes = 2.25 miles

15 minues = 3 miles

no youre too far and Amy is now further so we have to go back some

40 minutes = 2 miles

10 minutes = 2 miles

With all this being said Amy only needs to ride her bike for 10 minutes before she catches back up to Adam
