It’s 19. The absolute value of -7 is 7 and the absolute value of 4 is 4. 7 plus 3 times 4 is 19.

Answer:

c. 19

Step-by-step explanation:

The lines surrounding the numbers mean absolute value, which is the distance from zero. Basically what you have to remember is that if it's a positive with this symbol, you keep it the same, if a negative, you change it to positive. In this case, the I-7I would turn into a 7 and then 3*4=12. When you add 12 and 7, it equals 19. Hope this helps! :)

a mass of 40 grams cause a spring to stretch to the length of 40 cm, A mass of 60 grams causes it to stretch to a lenght of 6.7

uysha [10]

Answer

Part 1: l = -1.665g

Part 2: Max-mum the spring can support.

Part 3: The spring constant.

Explanation

Gradient is also called the slope.

Slope = (change in y) /(change in x)

= (60 -40)/(6.7 - 40)

= 20 / -33.3

= - 0.600600601

Since the graph is a straight line, the equation would be,

m ∝ l

m = kl Where K is the constant.

g = -0.60l

l = -1.665g

Part 2

The Y-intercept represent the mix-mum weight the spring can support.

part 3

The slope in this case represent the spring constant.

Simplify the expression to a polynomial in standard form: (−x+1)(x^2+6x−4)

OlgaM077 [116]

Answer:

-x^3-5x^2+10x-4

Step-by-step explanation:

(−x + 1) (x ^ 2 + 6x − 4) = (-x)(x ^ 2 + 6x − 4) + 1(x ^ 2 + 6x − 4)

= -x^3-6x^2+4x+x^2+6x-4 = -x^3-5x^2+10x-4
