Answer:

3x-4y=-40

Explanation

y-4=3/4(x+8)

distribute the 3/4

y-4= 3/4x + 6

add 4

y= 3/4x+10

then change to standard form

3x-4y=-40

Answer:

[tex]Z=x+y[/tex]

[tex]x+y<20[/tex]

Step-by-step explanation:

Let the gallons of fuel used in the hybrid per week car be [tex]x[/tex] and [tex]y[/tex] be the number of gallons used in the pickup truck per week.

Number of miles driven using both vehicles is at least 500 per week. The inequality that represents the number of miles driven is.

[tex]40x+17y\geq 500[/tex]

The expression of total amount of fuel used would be [tex]Z=x+y[/tex].

Now the sum of the fuels used in both the cars is more than 20 gallons per week. The inequality that represents the total amount of gasoline used is

[tex]x+y<20[/tex]

Answer:

The answer should be -19/13 per hour. I think, I'm not completely sure.

Step-by-step explanation:

Find the difference of 9 1/4 and 4 1/2

divide by 3 1/4

simplify

4 1/2 - 9 1/4 = -19/4

-19/4 divided by 13/4 = -76/52

-76/52 = -38/26 = -19/13

So the answer should be -19/13 per hour.

The requried rate of change in the tide level over this period of time is 19/13h.

Rate of change is defined as the change in value with rest to the time is called rate of change.

To find the rate of change, we need to divide the change in the tide level by the time elapsed:

Change in tide level = 37/4 - 9/2 = 37 - 18/4 = 19/4

Time elapsed = 13/4 h

Rate of change = Change in tide level ÷ Time elapsed
= 19/4 ÷ 13/4
= 19/13 h

So, the rate of change in the tide level over this period of time is 19/13h.

Answer:

The slope is $8 per hour

Step-by-step explanation:

Here, we want to get the slope of the relation

Mathematically, that will be;

m = y2-y1/x2-x1

Where ; (no of hours, money) represents each point

Thus, we have it that

m = (42-10)/(5-1) = 32/4 = $8/ hour

There's this weird phenomenon with parallel lines, that if you trace a line over it, you would get the same angle on the opposite side of the line.

Answer:

B.

Step-by-step explanation:

remember, solving this means to get the variable alone on one side (it does not matter which side), and everything else on the other side.

but whatever changes we do (except for just completing local operations that were already there), we always have to do them to both sides to keep the equality alive. if we introduce a change of quantity on one side only, we break the equality, and we will not get a valid result anymore.

A. subtract 5 from the left side : no, it changes only the left side. the equality is broken.

B. add 10x to both sides. yes, it applies the change to both sides and will bring all terms of x to one side. perfect.

C. subtract 11 from the right side. no, it changes only the right side. the equality is broken.

D. subtract 4x from both sides. no. it does change both sides and keeps the equality, true, but it does not help us in solving the equation. it still keeps a mixture of x terms and constant terms on both sides. nothing changes in the structure.

Answer:

C

Step-by-step explanation:

Answer:

The slope is -3.

Step-by-step explanation:

The slope is equal to the change in y over the change in x.

First, we take the two y values, -2 and -8, and subtract the SECOND from the FIRST: -2 - (-8) = -2 + 8 = 6 (= change in y)

Second, we take the two x values, 5 and 7, and subtract the SECOND from the FIRST: 5 - 7 = -2 (= change in x)

Finally, we make a fraction, the change in y over the change in x:

6/-2 = -3

The slope is -3.

Population growth rate of the bacterial culture can be expressed as a function of time as N = [tex]e^{kt + C}[/tex]

Step-by-step explanation:

If we assume the number of bacteria at any time (t) is (N). Then, the population of bacterial culture at that time is given by

N = N (t)

It is also given that the rate at which the bacterial culture will grow is proportional to its size. So, the growth rate is given by

dN/dt ∝ N

Removing the sign of proportionality, we get a constant

dN/dt = KN

We get

∫1/N dt = ∫K dt

After integration

ln N = Kt + C

N = [tex]e^{kt + C}[/tex]

C

Answer:

Yes, because two pairs of corresponding angles in the triangle are congruent. So the answer is A.

Step-by-step explanation:

Corresponding angles is an angle that is in the exact same spot as the other angle and they are congruent to each other which means that they have the same measure/number.

As the picture shows both triangles have all of their angles as the same measures.

The slope of the line shown is 1

The formula for calculating the slope of a line is expressed according to the formula

Slope = Rise/Run

Slope = y₂-y₁/x₂-x₁

Using the coordinate point (1,-2) and (3, 0)

Slope = 0+2/3-1
Slope = 2/2

Slope = 1

Hence the slope of the line shown is 1

The value of the polynomial function at p(-5) is 40.

A polynomial is an expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables and is made up of indeterminates (also known as coefficients) and these operations.

The given polynomial function is:

p(x) = x³ + 7x² - 20x -110

or, p(-5) = (-5)³ + 7(-5)² - 20(-5) -110

or,  p(-5) = -125 + 175 + 100 - 110

or,  p(-5) = 40

D. m<RST = 2(m<TSU)

Step-by-step explanation:

Given that m<RST = 76°, m<RSU = 48°, and m<TSU = 38°, this implies that:

SU is an angle bisector of angle RST. Thus,

m<RST is twice the measure of <RSU or <TSU.
