List five different vocabulary words that could be used to describe each given expression. A. −+ b. 20−3 c. +2

Marianna [84]

Complete Question:

List five different vocabulary words that could be used to describe each given expression.

$(a)\ a - d + c$

$(b)\ 20 - 3c$

$(c)\ \frac{b}{d + 2}$

Answer:

(a) Vocabulary words: sum, difference, total, subtract, add

(b) Vocabulary words: product, difference, subtract, times, less than

(c) Vocabulary words: quotient, sum, add, divide, ratio

Step-by-step explanation:

$(a)\ a - d + c$

The word problem of this is:

The addition of c to the difference between a and c

Keywords: addition and difference

Vocabulary words: sum, difference, total, subtract, add

$(b)\ 20 - 3c$

The word problem of this is:

The difference between 20 and the product of 3 and c

Keywords: difference and product

Vocabulary words: product, difference, subtract, times, less than

$(c)\ \frac{b}{d + 2}$

The word problem of this is:

The quotient of $b\ and\ the$ sum of d and 2

Keywords: quotient and sum

Vocabulary words: quotient, sum, add, divide, ratio

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!

Ratling [72]

Answer:

NF = 25

Step-by-step explanation:

Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.

This means that:

KF/ZF = NF/LF

KF = x + 3

ZF = 4

NF = 15 + x + 3 = x + 18

LF = x + 3

Plug in the values into the equation

(x + 3)/4 = (x + 18)/(x + 3)

Cross multiply

(x + 3)(x + 3) = (x + 18)(4)

x² + 3x + 3x + 9 = 4x + 72

x² + 6x + 9 = 4x + 72

x² + 6x + 9 - 4x - 72 = 0

x² + 2x - 63 = 0

Factorize to find x

x² + 9x - 7x - 63 = 0

x(x + 9) -7(x + 9) = 0

(x + 9)(x - 7) = 0

x + 9 = 0 or x - 7 = 0

x = -9 or x = 7

We'd use the positive value of x, which is 7.

Therefore, x = 7.

✅NF = 15 + (x + 3)

Plug in the value of x

NF = 15 + (7 + 3) = 15 + 10

NF = 25

Please help i need this as soon as possible

masya89 [10]

It's a quadratic so the parent function will be
$y = x ^{2}$
We can see that it has been shifted to the right 5 units, which gives us a new function
$y = (x - 5) ^{2}$
It has also been shifted up 9 units:
$y = (x - 5) ^{2} + 9$
But it has also been flipped across the y-axis which makes this the final change we need to do:
$y = - (x - 5) ^{2} + 9$

What is the slope of the line represented by the equation y =-1/2x + 1/4?

jarptica [38.1K]

The slope is -1/2x in this case because it is always next to a variable y=mx+b.
