Lisa and Kate are playing a card game, and a total of 900 points has been scored. Lisa scored 250 more points than Kate. If you

let l=l=the number of points that Lisa scored, and k=k= the number of points that Kate scored, then the problem can be represented by the system:
l+k=900l+k=900 and l=k+250l=k+250

Graph the system. How many points did each of them score?

Select one:
a. Kate = 575 and Lisa = 325
b. Kate = 250 and Lisa = 650
c. Kate = 450 and Lisa = 450
d. Kate = 325 and Lisa = 575

Answer:

Lisa score 575 points and Kate scored 325 points.

Step-by-step explanation:

We are given the following information:

Total score for Lisa and Kate is 900 and Lisa scored 250 more points than Kate.

Scores for Lisa and Kate can be expressed with the help of two equations:

L + K = 900\\L = K + 250 \Rightarrow L-K = 250

Solving these equations we have:

L + K + L - K = 900 + 250\\2L = 1150\\L = 575\\K = 575 - 250 = 325

Hence, Lisa score 575 points and Kate scored 325 points.

The graph of the equations is attached.

Janie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?
UkoKoshka [18]

Answer:

Option (D) is correct.

No, They will not intersect.

Step-by-step explanation:

Given Points for g(x), (1,2) , (2,4) and (3,6)

Since g is a linear function then it must be in form of  g(x) = mx +c where, c is constant and m is slope.

We first calculate the slope using,

m=\frac{y_2-y_1}{x_2-x_1}

Here, consider x_1=1 , x_2=2 , y_1=2, y_2=4

Substitute above, we get slope as,

m=\frac{4-2}{2-1}=2

Thus, equation becomes g(x) = 2x + c  ...(1)

For c plug the values  in (1),

(1,2) ⇒ 2= 2 + c ⇒  c = 0

Thus, Equation of G(x) is 2x.

When we plot it it do not intersect f(x).

Thus, Option (D) is correct.

No, They will not intersect.
