Answer:

CD = 7

Step-by-step explanation:

Given that the triangles are congruent, then corresponding sides are congruent, that is

CD = AB , substitute values

3y + 1 = 15 - 4y ( add 4y to both sides )

7y + 1 = 15 ( subtract 1 from both sides )

7y = 14 ( divide both sides by 7 )

y = 2

Thus

CD = 3y + 1 = 3(2) + 1 = 6 + 1 = 7

On the coordinate plane, ΔABC ≅ ΔDEF by SSS. ΔABC translates 2 units to the left and 3 units down. Do the triangles remain congr

MrRissso [65]

Yes because you are simply translating the shape and moving it and not changing the shape.

<h3><u>Answer</u> :</h3>

Let numerator of fraction be x and denominator be y.

∴ Fraction = x/y

★ <u>Part - A</u> :

$:\implies\tt\:\dfrac{x\times 4}{y-2}=2$

$:\implies\tt\:4x=2(y-2)$

$:\implies\tt\:4x=2y-4$

$:\implies\tt\:2y=4x+4$

$:\implies\bf\:y=2x+2\:\:\dots (1)$

★ <u>Part</u><u> </u><u>-</u><u> </u><u>B</u> :

$:\implies\tt\:\dfrac{x+15}{2y-2}=\dfrac{9}{7}$

$:\implies\tt\:7(x+15)=9(2y-2)$

$:\implies\tt\:7x+105=18y-18$

From equation (1)...

$:\implies\tt\:7x+105=18(2x+2)-18$

$:\implies\tt\:7x+105=36x+38-18$

$:\implies\tt\:29x=105-18$

$:\implies\tt\:x=\dfrac{87}{29}$

$:\implies\boxed{\bf{x=3}}$

$:\implies\tt\:y=2x+2$

$:\implies\tt\:y=2(3)+2$

$:\implies\boxed{\bf{y=8}}$

∴ Fraction = x/y = 3/8

(Q2) Which of the following points lies on the graph of the function y = 4x ?

stepladder [879]

Answer:

Step-by-step explanation:

I think I will answer the question the your attachment because it has full information.

The function is: y = 3* $2^{x}$

a. The function decreases

Wrong, because the base number is 2 and it is greater than 0. The function will go up

b. y=intercept of (0.2)

Wrong, Let substitute x =2 into the function: y = 3* $2^{2}$ = 12

c. if x increase by 1, the value of y will double

Because the base number is 2. For example:

If x = 2, y = 3* $2^{2}$ = 12

If x =3, y =3* $2^{3}$ =(3* $2^{2}$ *)2 = 24

d. contains the point (2,4)

Wrong, Let substitute x =4 into the function: y = 3* $2^{4}$ = 48

So we choose C

.35 as a percentage would be 35%.

.35 = 35 / 100 as a fraction
