use this formula the answer is down below.

[tex]\frac{ysub2-ysub1}{xsub2-xsub1}[/tex]

Step-by-step explanation:

this is y.   -15-18= -33

this is x.    0--12 (so in this case you would add 12)

the slope is -33/12

Answer:

this is true :)

Step-by-step explanation:

Yes, a system of two equations in two variables whose graphs are a parabola and a circle can have four real ordered-pair solutions.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.

Given that a system of two equations in two variables whose graphs are a parabola and a circle can have four real ordered-pair solutions.

It is because the there are two systems of equations and two variables in it.

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]

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:

V=22/7×r^2×h

=22/7×(5.93/2)^2×10

=276.26cm

Step-by-step explanation:

Use the equation V=22/7×r^2×h

V=volume

r=radius

h=height

Substitute the values for r and h, then find the value for V

The volume of cylinder is 276.04 cm³.

The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder.

Given:

d= 5.93

h= 10cm

r= 5.93/2

Now, volume of cylinder

= πr²h

= 3.14 x 5.93/2 x 5.93/2 x 10

= 31.4 x 8.7912

= 276.04 cm³

Hence, the volume of cylinder is 276.04 cm³.

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))

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]

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.

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]

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.
