Answer:

The first and last graph.

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.

Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.

Answer:

3x - 125 = -5

Answer:

both negative

Step-by-step explanation:

Descartes rule of signs tells us how many positive and negative real roots a polynomial has.

Given

f(x) = x² + 5x + 6 , with signs

+, +, + ← no change of signs, thus no positive zeros

f(- x) = (- x)² + 5(- x) + 6 = x² - 5x + 6 , with signs

+, -, + ← with 2 changes of signs. thus 2 negative zeros

Answer:

B) Both Negative

Step-by-step explanation:

[tex](x^2+5x+6)\\=(x^2+2x+3x+6)\\=x(x+2) + 3(x+2)\\=(x+3)(x+2)\\Hence,\ as\ their\ factors\ are\ (x+3)\ and\ (x+2)\ their\ zeroes\ are\ (-3)\ and\ (-2)\ respectively..\\As\ they\ both\ are\ negative..\ the\ answer\ is\ b)\\\[/tex]

The answer is  y= 23/4

The value of function  f(4) is 27.

It is required to find the value of function  f(4).

What is function?

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given that:

The function is

f(x) = 6x +3

Now put the value x=4 in the given function, we get

f(4)=6(4) +3

= 24+3

=27

f(4)=27.

Hence, the value of function  f(4) is 27.

Answer:

y=2x+3

Step-by-step explanation:

1. y+7=2(x+5) (rewrite the problem)

2. y+7=2x+10 (distribute the 2)

3. y=2x+3 (subtract 7 from both sides; 10-7=3)

Answer:

[tex]\frac{7}{8}[/tex]

Step-by-step explanation:

To find the total amount of flour and sugar, you have to find a common denominator for the two fractions and then add them together.

[tex]\frac{1}{2}[/tex] multiplied by 4 equals [tex]\frac{4}{8}[/tex].

Now that the fractions both have a common denominator of 8, we can add them together:

[tex]\frac{3}{8}[/tex] + [tex]\frac{4}{8}[/tex] = [tex]\frac{7}{8}[/tex]

The total amount of flour and sugar is [tex]\frac{7}{8}[/tex]

Answer:

23.5 gallons

Step-by-step explanation:

The gas tank in Daniel's car has a capacity of 19.1 gallons.  

On a trip to see his best friend Daniel begins with 12.8 gallons of gas in the tank.  

He stops after driving for 2 hours and fills the tank to capacity with 14.4 gallons.  

When Daniel arrives at his friend's house, he has 3.7 gallons of gas left.  

Total amount of gas filled was (12.8 + 14.4) = 27.2 gallons.

The amount of gas remaining after the trip was 3.7 gallons

The amount of gas, in gallons, used by Daniel on his trip was 27.2 - 3.7 = 23.5 gallons

Answer:

35 cm^2

Step-by-step explanation:

To find the area you need to find the width and height which we have.

Now all you need to do is to use the formula Height x Width= area

so replace height with 5 cm and width with 7 cm

5 cm x 7 cm = area

5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)

Hope this helps!

Answer:

its either 35 or 70

Step-by-step explanation:

multiply 5 and 7 to get 35 or multiply 5 x 7 twice and get 70 pls mark brainliest me nub

Answer:

t = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

10t - 19 = 7t - 14

Subtract 7t from both sides;

3t - 19 = -14

Add 19 to both sides;

3t = 5

Divide both sides by 3;

t = [tex]\frac{5}{3}[/tex]

100+62.50=162.50

Answer:

Each student should pay $6.50

Step-by-step explanation:

The question is not very clear.

If Mr. Richard has to pay to enter:

Total cost = $100 + ($2.50×26) = $165

Cost per student = [tex]\frac{165}{25}[/tex] = $6.60

Each student should pay $6.60

If Mr. Richard doesn't have to pay to enter:

Total cost = $100 + ($2.50×25) = $162.5

Cost per student = [tex]\frac{162.5}{25}[/tex] = $6.50

Each student should pay $6.50

Answer:

y = 6x + 10

Isaiah makes $34.00 after working for 4 hours.

Step-by-step explanation:

Slope intercept form is y=mx+b

In this situation the equation would look like so, x = amount of hours:

y = 6x + 10

To solve for how much Isaiah earns after 4 hours plug in 4 instead of x.

y = 6(4) + 10

y = 24 + 10

y = 34

Isaiah makes $34.00 after working for 4 hours.

Hope that helps and have a great day!

Answer:

x=60

Step-by-step explanation:

Answer:   The equation  60 + x= 3x -70   could be set up to solve for x.  

Step-by-step explanation:

The two remote  interior angles sums will equal to the exterior angle .

Meaning that angle 60 plus angle x has to equal to angle 3x -70.

60 + x= 3x -70       Now solve for x by adding 70 to both sides

+70             +70

  130 + x = 3x      Now subtract x from both sides

         -x      -x

  130 = 2x        Divide both sides by

  x = 65

Step-by-step explanation:

Answer: B. f(x)=(x+4)(x-2)^2(x+3)

Step-by-step explanation:

in the graph there's two negative x value and one positive x value

so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)

the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))
