Brad can make 4 key chains in an hour. Velma can make only 3 key chains in an hour, but she already has 6 completed key chains. How can Brad use a system of equations to determine when he will have the same number of key chains as Velma?

Answers

Let us assume that the time after which Brad will have the same number of key chains as Velma = x hours
We already know that
Number of key chains Brad can make in an hour = 4
Number of key chains that Velma can make in an hour = 3
So after x hours,
Number of key chains that Brad can make = 4x
Number of key chains that Velma can make = 3x
Number of key chains that Velma already has = 6
Then the equation will be
3x + 6 = 4x
4x - 3x = 6
x = 6
So, from the above deduction, we can conclude that after 6 hours Brad will have the same number of key chains as Velma.

ΔABC is reflected across line L to form Δ ALBLCL, and intersects line L at point D. Which equation is not necessarily true?

Answers

option 2
ALD=BLD equation is not necessarily true, all other remaining equations satisfy laws of reflection.

Answer:

$A_LD= B_LD$ is false statement.

B is correct

Step-by-step explanation:

$\triangle ABC$ is reflected across line L to form $\triangle A_LB_LC_L$ .

If we join A and $A_L$ and intersect line L at point D.

Reflection: A transformation of a geometric figure such that creating a mirror image across the line. The line of reflection is called axis of reflection.

As we know mirror image figure has same property their side measure and angle measure equal.

$\triangle ABC \text{ is congruent to }\triangle A_LB_LC_L$ .

Distance of each vertex of figure from axis of reflection line is equal to their corresponding vertex.

Therefore, True statements are:-

$AD=A_LD$

$\angle ACB=\angle A_LC_LB_L$

$\angle BAC=\angle B_LA_LC_L$

$A_LD\neq B_LD$

Please find the attached figure for reflection and coordinates.

Hence, $A_LD= B_LD$ is false statement.

3x+4y=5 2x-5y=8
Is this consistent and independent, consistent and dependent, or inconsistent

Answers

3x + 4y = 5
2x - 5y = 8

To answer this question, we need to put both of these equations into Slope-Intercept form, or in other words, solve for y.

3x + 4y = 5 Subtract 3x from both sides
4y = -3x + 5 Divide both sides by 4
y = $-(3)/(4)$ + $(5)/(4)$

2x - 5y = 8 Subtract 2x from both sides
-5y = -2x + 8 Divide both sides by -5
y = $(2)/(5)$ - $(8)/(5)$

When you look at the two equations, you can see that their slopes are completely different, so they aren't parallel, or inconsistent. Since $(2)/(5)$ is not the same as $-(3)/(4)$ , they aren't the same line, or dependent. So, the only option left is that they are consistent and independent.
