Solve the system for x and y.

-8x - 5y = -1
-8x - y = -45

Answer:

$9.50

Step-by-step explanation:

40x + (5*1.5*x) = 451.25

40x + 7.5x = 451.25

47.5x = 451.25

x = 9.50

Answer:

A.) Both lines pass through the point represented by the ordered pair

Step-by-step explanation:

Both lines pass through the point represented by the ordered pair.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

An ordered pair is a solution of a system of linear equations by examining the graphs of the equations.

We know that;

An ordered pair is a solution of a system of linear equations when both the lines are passing through the same ordered pair.

Hence, We get the correct sentence is,

''Both lines pass through the point represented by the ordered pair.''

Answer:

Step-by-step explanation:

Concavity of a quadratic function is determined the leading coefficient.

If the leading coefficient is positive, graph will entirely concave upwards.

If the leading coefficient is negative, graph will concave downwards entirely.

So in the interval (-∞, ∞) function has the positive concavity.

There is no interval in which the given function has the negative concavity.

Answer:

A 31/45

Step-by-step explanation:

A 31/45=0.6888 (this is the awnser as the line on top means repeating)

B 682/999=0.682 (0.68 rounded)

C 62/99=0.62626 (repeating)

D 2/3=0.66666 (Or 0.67 rounded)

Answer: Then the magnitude of the force is 37.86N, and the direction is 54.35°

Step-by-step explanation:

We can write the forces as vectors.

We know that Annie pushes with a magnitude of 80N in a direction of 133° (Remember that the angles are always measured from the x-axis)

The components of this force, (Ax, Ay), are then:

Ax = 80N*cos(133°)

Ay = 80N*sin(133°)

And we know that Josie pushes with a magnitude of 95N in direction of 290°

The components of this force, (Jx, Jy), are:

Jx = 95N*cos(290°)

Jy = 95N*sin(290°)

When we add these forces, the total force acting on the ball is:

F = (80N*cos(133°) ,  80N*sin(133°)) + (95N*cos(290°), 95N*sin(290°))

F = (80N*cos(133°) + 95N*cos(290°), 80N*sin(133°) + 95N*sin(290°))

Now, the third kitten wants to do a force K, in a direction θ, such that the net force acting on the ball is zero.

Then we must have that, each component of the force of the third cat (K*cos(θ)  on the x-axis and k*sin(θ) on the y-axis), is such that:

K*cos(θ) + 80N*cos(133°) + 95N*cos(290°) = 0

k*sin(θ)  + 80N*sin(133°) + 95N*sin(290°) = 0

Now we need to solve that system for k and θ

if we simplify the equations we get:

k*cos(θ) - 22.07N = 0

k*sin(θ)  -30.76N  = 0

Now we can rewrite them as:

k*cos(θ) = 22.07N

k*sin(θ)   = 30.76N  

Now we can take the quotiet between both equations to get:

(k*sin(θ))/(k*cos(θ)) = 30.76N/22.07N

Tan(θ) = 1.394

θ = Atan(1.394) = 54.35°

Now that we know the angle, we can find the value of the magnitude k, by using one of the two equations of the system:

k*cos(54.35°) = 22.07N

k = 22.07N/cos(54.35°) = 37.86N

Then the magnitude of this force is 37.86N, and the direction is 54.35°

Answer:

a dilation is different from a translation because it enlarges an image or shrink them instead of moving them. it's also different from rotation since it doesn't rotate but enlarge or shrink. it's way far from reflection because it enlarges or shrinks.

Answer: A diliation is a non rigid transformation, whereas reflections, transitions and rotations are rigid transformations. This means that dilations do not preserve the size of the shape.

The answer is

J) 334.06

Step-by-step explanation:

We know the rate is 1.5 inch an hour

So 1.5*2.54 is 3.81

Now 3.81 cm every hour

24 hours a day

3.81*24=91.44

Now 91.44 cm A day

1 Year or 365 days

91.44*365= 33375.6cm a year

now we also need to add the extra 12 inches in the beginning

12*2.54=30.48cm

Now add those 2

33375.6+30.48= 33406.08

now the answer asked for meters so we divide 33406.09/100

you’ll get 334.06 or J

Explanation:

A percentage is a representation of a fraction. Just as any fraction relates a quantity to a whole, so does a percentage.

Example:

  3/5 represents 3 parts out of 5.

Its equivalent as a percentage is ...

  3/5 · 100% = 60%

which also represents 3 parts out of 5, or 6 parts out of 10, or 60 parts out of 100.

__

Note that the percent symbol (%) can be considered to be a shorthand way to write /100. Similarly, the "mils" symbol (‰) can be considered a shorthand way to write /1000. That is, 60% is fully equivalent to 60/100, and vice versa.

Answer:

First, let's do some general definitions:

We start with:

f(x) = 3.5*x^3

A general equation of this form is:

g(x) = a*x^3

if:

IaI > 3.5 the function will be steeper.

IaI < 3.5 the function will be less steep.

a < 0, means that we have a reflection over the x-axis.

Then:

p(x) = 4.5*x^3

bassed on what we wrote above, this function is steeper than f(x)

q(x) = -x^3

This is less steep ( a = -1 in this case) and we also have a reflection over the x-axis.

r(x) = 3*x^3

In this case 3 < 3.5, this means that this will be lees steep than f(x)

i do not think the order matters, so the answer should be the first two.
