Answer:

c. Change the length of side CB to 8 feet

Step-by-step explanation:

If the figures are similar, the ratios should be the same

Take the side of the larger triangle over the same side of the smaller


PR                PQ                     RQ

----------- = --------------------= ----------------

AC                AB                      CB


7.5                5                       10

----------- = --------------------= ----------------

 6                4                        9

7.5 /6 = 1.25

5/4 = 1.25

10/9 =1.1111(repeating)


The bases are not in the right ratio.  RQ over CB = 1.25.  Since RQ = 10  and the ratio is 1.25, we can solve for CB

10/CB = 1.25

Multiply by CB on each side

10 = 1.25CB

Divide by 1.25 on each side

10/1.25 = CB

8 =CB

Write equation of the line containing (4,2) and (3,5)<br> in slope-intercept form.
11Alexandr11 [23.1K]

Answer:

The equation of the line containing (4,2) and (3,5)  in the slope-intercept form will be:

  • y=-3x+14

Step-by-step explanation:

Given the points

  • (4, 2)
  • (3, 5)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(4,\:2\right),\:\left(x_2,\:y_2\right)=\left(3,\:5\right)

m=\frac{5-2}{3-4}

m=-3

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept

substituting m=-3 and the point (4, 2) to get the y-intercept i.e. b

y=mx+b

2=(-3)4 + b

2 = -12 + b

b = 2+12

b = 14

Now, substituting b=14 and m=-3 in the slope-intercept form to determine the equation of a line in the slope-intercept.

y=mx+b

y=(-3)x+(14)

y=-3x+14

Thus, the equation of the line containing (4,2) and (3,5)  in the slope-intercept form will be:

  • y=-3x+14
