Suppose a system of two linear equations has one solution. What must be true about the graphs of the two equations?

When two linear equations have only one solution the two lines on a graph would intersect each other ( they would only touch in one spot).

The domain of y=log(9-x^2),xER, is

jasenka [17]

Step-by-step explanation:

log(z) is defined when z > 0.

For log(9 - x²) to be defined, we have 9 - x² > 0.

=> x² < 9, -3 < x < 3.

The domain of y = log(9 - x²) is (-3,3).

Which ratio is greater than 5/8 , A. 12/24 B. 3/4 C. 15/24 D.4/12

-Dominant- [34]

Answer:

B. 3/4

Step-by-step explanation:

5/8 Get a common denominator of 24

5/8 *3/3 = 15/24

A. 12/24 this is less than

B. 3/4 *6/6 = 18/24 greater than

C. 15/24 same value so equal to

D.4/12 * 2/ = 8/24 less than

Which description is true about pre-image ABC and image A′B′C′ ?

scoray [572]

Answer:

Option (C)

Step-by-step explanation:

From the graph attached,

In ΔABC and ΔA'B'C',

∠A ≅ ∠A'

∠B ≅ ∠B'

Therefore, ΔABC ~ ΔA'B'C'

Corresponding sides of these triangles will be proportional.

$\frac{\text{AB}}{\text{A'B'}}=\frac{\text{BC}}{\text{B'C'}}=\frac{\text{AC}}{\text{A'C'}}=\frac{2}{6}$

Therefore, ratio of the sides, AC : A'C' = 1 : 3 shows that image triangle A'B'C' is a dilated form of pre-image ABC with a scale factor of 3.

Option (C) will be the correct option.
