Answer:

d. The slope is −0.3. Starting at 3.9, the GPA will decrease by 0.3 for every text sent in class.​

Step-by-step explanation:

You can write the equation is the slope intercept form of y=mx+c

where m is the slope and c in the y-axis intercept

write the equation as;

y=mx+c

y= -0.3x+3.9

Here , you have a negative slope which means the GPA will reduce by 0.3 for every text sent in class.

See attached graph to visualize the y-intercept point

Answer:

The correct option is d.

Step-by-step explanation:

The given equation of best fit line is

[tex]y=3.9-0.3x[/tex]              .... (1)

The slope intercept form of a line is

[tex]y=mx+b[/tex]               .... (2)

where, m is slope and b is y-intercept or initial value.

From (1) and (2), we get

[tex]m=-0.3[/tex]

[tex]b=3.9[/tex]

It means the slope is −0.3. Starting at 3.9, the GPA will decrease by 0.3 for every text sent in class.​

Answer:

Step-by-step explanation:

It never occurred to me that the closed circle meant multiplication. The most common symbol for multiplication here is *. If that is what is meant (closed circle = multiplication) then my answer is wrong.

f(x) = 3x + 1

g(x) = x^2 - 6

f(x)(g(x)) = (3x + 1)(x^2 - 6)

f(x)(g(x)) =  3x^3 - 18x + x^2 + 6 or more properly

f(x)(g(x)) = 3x^3 + x^2 - 18x - 6

[tex](f\cdot g)(x)=(3x+1)(x^2-6)=3x^3-18x+x^2-6=3x^3+x^2-18x-6[/tex]

Answer:

13

Step-by-step explanation:

If you look at where $5 crosses the line of best fit, you see it between 12 and 14 ounces. The answer is 13.

Answer:

13 oz

Step-by-step explanation:

The blue line here is the trend line of the function between cost and size.

The trend line is the linear equation approximation of the function

So, for predicting the size when $5 is paid we need to take the corresponding x axis value and the corresponding y axis value on the trend line.

Hence, the Size of frozen yogurt is between 12 and 14 oz which means the size is 13 oz.

Answer:

see explanation

Step-by-step explanation:

Note that

(f + g)(x) = f(x) + g(x) and

(f - g)(x) = f(x) - g(x)

5

f(x) + g(x)

= 5x² + 3 + x² - 7 = 6x² - 4

6

f(x) - g(x) = 5x² + 3 - (x² - 7) ← distribute parenthesis

              = 5x² + 3 - x² +7 ← collect like terms

              = 4x² + 10

Step-by-step explanation:

The given question is of subtraction:

So,

(7z^3+42z^2-15z+1)- (36z^2+12z-21)​

=7z^3+42z^2-15z+1-36z^2-12z+21

Combining alike terms to simplify

=​7z^3+42z^2-36z^2-15z-12z+1+21

=7z^3+6z^2-27z+22

So the answer in simplified form is:

7z^3+6z^2-27z+22 ..

Answer:

7z³ + 6z² - 27z + 22

Step-by-step explanation:

It is given an expression in variable z,

(7z³ + 42z²  - 15z + 1) - (36z² + 12z - 21)​

To find the simplified form

(7z³ + 42z²  - 15z + 1) - (36z² + 12z - 21)​

 = (7z³ + 42z²  - 15z + 1 - 36z² - 12z +  21)​

 = 7z³ + 42z² - 36z² - 15z -12z + 1 + 21

 = 7z³ + 6z² - 27z + 22

Therefore the simplified expression is = 7z³ + 6z² - 27z + 22

Answer:

C. (-5, 3)

Step-by-step explanation:

Point C is currently (5,3).

If it is reflected over the y-axis, that means while the y-coordinate stays the same, the x- coordinate is negative of what is was before.

C is the only answer that keeps the y-coordinate constant, so just by looking at that, we can say that the answer is C.

Answer:

C

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y )

Hence

C(5, 3 ) → C'(- 5, 3 ) → C

Answer:

Similar but not congruent

Step-by-step explanation:

For them to be congruent, they have to have same everything but not necessarily the same orientation.  They are not congruent because their corresponding sides aren't the same measurement.

You can tell if two triangles are similar if each pair of corresponding are congruent.

They will also have corresponding sides are proportional.

That is 50/40=60/48=40/32 in this case? Well does it?  It does, because each one of them is equal to 1.25.

Answer:

The correct answer is second option

They are similar, but not congruent

Step-by-step explanation:

From the given diagram we can see two triangles.

ΔUVW and ΔXYZ

m<X = m<U,

m<Y = m<V and

m<Z = m<W

Therefore two triangles are similar

The sides of these two triangles are not congruent, therefore these two triangles are not congruent.

The correct answer is second option

They are similar, but not congruent

Answer:

-3

Step-by-step explanation:

To find the slope of a line given two points, we use:

[tex]\frac{y_2-y_1}{x_2-x_1} \text{ when the points } (x_1,y_1) \text{ and } (x_2,y_2) \text{ are on the line }[/tex].

Or you could line up the points vertically and subtract the points vertically, then put 2nd difference over 1st difference.

That looks like this:

(  2  ,  -12)

-( -5  ,  9   )

----------------

  7         -21

So the slope is -21/7 which gives you -3.

Answer:

B. Many-to-many

Step-by-step explanation:

We have the following ordered pairs:

First let's define the following concepts:

From all the ordered pairs, we find that the points (1,2) and (1,3) have the same x-value for diferent y-values. Also we find that the points (1,2) and (-2, 2) have different x-values for the same y-value.

Therefore, the ordered pairs DO NOT belong to a function and can be considered MANY-TO MANY.

The given relation is a many-to-one relationship.

The given relation {(1,2), (-2,3), (1,3), (-2,2)} is an example of a many-to-one relationship. In a many-to-one relation, multiple elements in the domain map to a single element in the range. Each x-value has a unique y-value.

Answer:

A. 40.076

Step-by-step explanation:

Because B is forty and seventy six hundredths. C is forty-seven and six thousandths. D is forty-seven and six hundredths.

Seventy-six thousandths is written as .076, making the final answer 40.076.

The decimal equivalent to forty and seventy six thousandths is 40.076. This is because seventy-six is in the thousandths place after the decimal point.

The decimal equivalent to forty and seventy six thousandths is 40.076. To write this out, you place the decimal point after the whole number forty, then you need to ensure that seventy-six is in the thousandths place. When writing decimal numbers, the first place to the right of the decimal is the tenths place, the second is the hundredths place, and the third is the thousandths place. Therefore, seventy-six thousandths is written as .076, making the final answer 40.076.

Answer:

Answer:

B

Step-by-step explanation:

recall that point-slope form of a linear equation is expressed as follows

y - y1 = m (x - x1)

where m = slope and (x1, y1) is the coordinate of any point on the line

so, here we have m = (3/5), x1 = 4 and y1 = -6

substitute these into the formula

y - (-6) = (3/5) (x - 4)

y + 6 = (3/5) (x - 4)----> answer

Answer:

[tex]\boxed{\text{B. }y + 6 =\dfrac{3}{5}(x - 4)}[/tex]

Step-by-step explanation:

The point-slope formula for a straight line is

[tex]y - y_{1} = m(x - x_{1})[/tex]

x₁ = 4; y₁ = -6; m = ⅗  

Substitute the values

[tex]\begin{array}{rcl}y - (-6) & = & \dfrac{3}{5}(x - 4)\\\\y + 6 & = & \dfrac{3}{5}(x - 4)\\\\\end{array}\\\text{The equation for the line is $\boxed{\mathbf{y + 6 =\dfrac{3}{5}(x - 4)}}$}[/tex]

The figure shows the graph of the equation with slope ⅗ passing through (4,-6).

Putting two or more equations in a system means to find the set of variables that satisfies all the equations at the same time.

Moreover, the points that satisfy an equation are the points that lay on the graph described by the equation.

So, putting everything together, solving a system means to lay on all the graphs at the same time. In other words, the solutions of a system are the points of intersection between the graphs that represent the functions involved in the system.

In this case, the line and the circumference have two points of intersection, and they are the two solutions of the system.

In the absence of the graph, one can still note that the number of solutions a nonlinear system of equations has depends on the points of intersection of the curves represented by the equations. Each point of intersection represents a solution.

Unfortunately, without the graph, it is rather difficult to directly answer how many solutions the nonlinear system of equations has. In general, the number of solutions for a nonlinear system of equations can be determined by where the curves represented by the equations intersect. The point of intersection is considered a solution. This is because at this point both equations hold true. If the curves intersect once, then there is one solution. If they intersect twice, then there are two solutions. If they never intersect, there are zero solutions.
