<u>Answer:</u>

1. The numerator has three terms.

2. The denominator includes a coefficient of 2.

<u>Step-by-step explanation:</u>

We are given the following expression and we are to determine whether which of the given statements are true for it:

\frac { -10 x ^ 2 + 5x + 3 } { 2x^2 + 4 }

So the true statements for this expression are:

1. The numerator has three terms:

(-10x^2 , 5x and 3 are the three terms in the denominator of this expression)

2. The denominator includes a coefficient of 2:

(the first term of the denominator 2x^{2} has a coefficient of 2)

Answer:

a)Numerator has 3 terms

c)Denominator includes a coefficient of 2

Step-by-step explanation:

Given the expression in the question

       -10x² + 15x + 3 / (2x² + 4)

<h3>1) </h3><h3>Numerator has 3 terms</h3>

Numerator is the upper part of fraction which in this case is -10x² + 15x + 3 and a term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or - sign.

<h3>2) </h3><h3>Denominator includes a coefficient of 2 </h3>

Denominator is the lower part of fraction which in this case is 2x² + 4 and coefficients are the constants by which the variables are being           multiplied.

Find the slope between the two given points in questions 3-4.
Sophie [7]
I think you have to figure out the gradient, so you take the 2 points and put it into the equation
change in y divided by change in x aka
y2-y1/x2-x1

so for question 3:
y2=4 and y1=3
(taken from the first and second coordinates)
x2=3 and y1=7
put these values jnto the equation
4-3/3-7 = 1/-4 (can be written as negative 1/4)

for question 4 its the same thing:
y2=9 and y1=5
x2=4 and x1=2
put into equation
9-5/4-2 = 4/2

hope this helps, im also hoping your teacher already has taught this because i didnt go into detail of where the equation came from, if not ask me and ill gladly help X

Walt and Hank collect quarters from different states. Walt collected q quarters. Hank collected four fewer quarters than Walt. T
SpyIntel [72]

Answer:

Walt has 37 quarters.  Hank has 33.

Step-by-step explanation:

Solve the given equation for q:

0.25q + 0.25q - 1.00 = 17.50

Simplify this, obtaining:

0.50q = 18.50

Simplifying this by multiplying both terms of this result by 100:

50 q = 1850

Thus, q = 1850/50 = 37

Walt has 37 quarters.  Hank has 33.

Note that 37 + 33 = 70, and that 70($0.25) = $17.50.  So our results are correct.
