Answer:

  \overline{CS}\cong\overline{ST}

Step-by-step explanation:

The congruence statement for the triangles does not list point (or angle) S, so no claim about segments or angles involving S will be supported by the congruence statement.

The statement

  \Delta BAT\cong\Delta CAT tells you ...

     \angle TBA\cong\angle TCA\\\angle BAT\cong\angle CAT\\\angle ATB\cong\angle ATC\\\overline{BA}\cong\overline{CA}\\\overline{AT}\cong\overline{AT}\\\overline{TB}\cong\overline{TC}

No other claims can be made using CPCTC. The statement among the answer choices that is not true by CPCTC is ...

  \boxed{\overline{CS}\cong\overline{ST}}

Answer:

Option (D)

Step-by-step explanation:

If the two points (x_1,y_1) and (x_2,y_2) are lying of the line.

Slope of the line represented by the function 'f' = \frac{y_2-y_1}{x_2-x_1}

Two points are lying on the line are (-2, 4) and (0, -2).

Slope of the line passing through these points 'm' = \frac{4+2}{-2-0}

m = -3

Y-intercept of the line 'b' = -2 [From the graph]

Therefore, equation of the function will be,

f(x)  = (-3)x - 2

f(x) = -3x - 2

Similarly, for other function represented by the line in red,

Slope of the line passing through (-6, 0) and (0, 6) = \frac{6-0}{0+6}

m' = 1

Y-intercept of g(x) = 5 [From the graph]

Equation that represents the function g(x) = 1.x + 5

g(x) = x + 5

For g(x) = f(x)

-3x - 2 = x + 6

-3x - x = 2 + 6

-4x = 8

x = -2

Therefore, for x = -2 both the functions will have the value.

f(-2) = g(-2)

Option (D) will be the answer.

3. Sophie and Jackie each have a collection of baseball cards, Jackie has 5 more cards than
IRISSAK [1]

Answer:

Sophie has 12.5 cards

Step-by-step explanation:

Let

x -----> number of cards Sophie has

y -----> number of cards Jackie has

we know that

x+y=30 -----> equation A  

y=x+5 -----> equation B

Solve by substitution

Substitute equation B in equation A and solve for x

x+(x+5)=30

2x=30-5

x=12.5 cards

Note I assume the problem was invented without taking into account the result, because the amount of cards should be a whole number
