If -10x+3y = 9 and -4x+7y =1 are true equations,what would be the value of -6x-4y

Answers

Answer:

8

Step-by-step explanation:

Notice: we do not have to solve for x, and y. All we really have to do is to subtract the two equations.

(-10x + 3y) - (-4x + 7y) = 9 - 1.

Taking off the parentheses, we get:

-10x + 3y + 4x - 7y = 8.

Simplifying, we get:

-6x - 4y = 8.

So, the answer is 8.

What is the slope of a line perpendicular to the line whose equation is x + 2y =8.
Fully reduce your answer.

Answers

Answer:

2

Step-by-step explanation:

First, put the line into y = mx + b form to find the slope (m)

x + 2y = 8

Subtract x from both sides

2y = -x + 8

Divide each side by 2

y = -1/2x + 4

So, the slope of this line is -1/2

Perpendicular lines have a opposite reciprocal slope, so the slope of a perpendicular line will be 2.

Answer:

a=40 degree( vertically opposite angle)

a+b+90=180( area of triangle)

or, 40+ b+ 90=180

or,b=180-130

b=50 degree

c+65=180 (st.line)

or, c= 180-65

c= 115 degree

Answers

Answer:

there are 3 1/6 pieces

Step-by-step explanation:

since 3 x 1/6=3/6.

another explanation:

(3/6)/(1/6)=(3/6) x (6/1) since you multiply by inverse when dividing fractions. Then, (3/6) x (6/1) = 18/6, which equals 3.

An iPad that was originally on sale for $1075 is now on sale for $ 623.50. What is the percent markdown( percent decrease)?

Answers

Answer = 58%

Explanation : you would have to set up a portion table were the sale amount (623.50) would go and the original/total price would go (1075$) and since you are trying to find the % you would put x over 100 , and then cross multiply while it’s set up so 623.50 times 100 =62,350 and you would take the answer and divide it by 1075x which would get you to 58 and that would equal x .

The product of (a − b)(a − b) is a perfect square trinomial.

A. Sometimes
B. Always
C. Never

Answers

Answer:

Always.

Step-by-step explanation:

Answer:

Always

Step-by-step explanation:

The first term of the product is always the first term of the original binomial squared.

The middle term of the product is always negative and equal to twice the product of the first and last terms of the original binomial.

The last term of the product is always positive and equal to the last term of the original binomial squared.

EX: Find the product of (3x − 4)2.

Identify what a and b are in the given binomial. Here, a is equal to 3x and b is equal to 4.

(3x − 4)2

substitute a for 3 times x and substitute b for 4 a     b

Now, substitute the values for a and b into a2 − 2ab + b2.

a2 − 2ab + b2

Make sure you place the term in parentheses when it involves more than one factor. Then, use the Power of a Product rule to simplify.

(3x)2 − 2(3x)(4) + (4)2

32x2 − 24x + 16

9x2 − 24x + 16

Done!
