There were 3 boys for every 4 girls in the group. If there were 20 girls, how many students in all went on the field trip?

Answer:

w = - 15

Step-by-step explanation:

Assuming you mean

[tex]\frac{w+3}{3}[/tex] = - 4 ( multiply both sides by 3 to clear the fraction )

w + 3 = - 12 ( subtract 3 from both sides )

w = - 15

Answer:

w= -5

Step-by-step explanation:

w+3/3= -4

w= -4-1... which is  (-4) + (-1) so,

w= -5

Step-by-step explanation:

value of discriminant:

[tex]5^{2} - 4 (2)(-4)\\=25+32\\=57\\[/tex]

As the value of discriminant is larger than zero, so there are 2 distinct solutions.

2 solutions also mean there are 2 x-intercepts.

Answer:

B

Step-by-step explanation:

It appears to be B because this quadratic function faces down (-ax^2) and the vertex or highest point of this function is when x=1. Thus, the interval of the domain that the function increases must be from negative infinity to 1, giving the answer B.

Answer:

16 v^3 w^7

Step-by-step explanation:

Simplify the following:

4 v^3 w (-2 w^3)^2

Hint: | Distribute exponents over products in (-2 w^3)^2.

Multiply each exponent in -2 w^3 by 2:

4 v^3 w×(-2)^2 w^(2×3)

Hint: | Multiply 2 and 3 together.

2×3 = 6:

4×(-2)^2 v^3 w w^6

Hint: | Evaluate (-2)^2.

(-2)^2 = 4:

4×4 v^3 w w^6

Hint: | Combine products of like terms.

4 v^3 w×4 w^6 = 4×4 v^3 w^(1 + 6):

4×4 v^3 w^(1 + 6)

Hint: | Evaluate 1 + 6.

1 + 6 = 7:

4×4 v^3 w^7

Hint: | Multiply 4 and 4 together.

4×4 = 16:

Answer: 16 v^3 w^7

y = 1/2x + 2

Step-by-step explanation:

Answer:

[tex]y=\frac{1}{2}x+2[/tex]

Step-by-step explanation:

To find the equation for the line, lets try to find the slope and y-intercept of the line.

From looking at the graph, we can see that the line intersects the y-axis at y = 2. So the y-intercept would be 2.

The slope of the line would be the rise divided by the run. Looking at the graph, we can see that for every 2 the line moves in the x-direction, it moves 1 in the y-direction. This means that the rise is 1 and the run is 2. So the slope would be 1/2.

So we now know that the slope is 1/2 and the y-intercept is 2, we can now plug the information into the slope-intercept form.

Slope-intercept form is:

y = mx + b

where m is the slope and b is the y-intercept.

Plugging in we get

[tex]y=\frac{1}{2}x+2[/tex]

And now we have the equation of the line.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

The equation of the line that passes through the point (-7, -8) and parallel to the given line is y = 5/7·x - 3

Step-by-step explanation:

The coordinates of the point the line passes = (-7, -8)

The equation of the line the required line is parallel to is y = 5/7·x - 5

The slope of of the given line is therefore in slope and intercept form with the slope = 5/7 and the y-intercept = -5

The slope of a line parallel to another line are equal, therefore the slope of the required line = The slope of the given line = 5/7

The equation of the required line in point slope form is therefore;

y - (-8) = 5/7 × (x - (-7))

y + 8 = 5/7 × x + 5/7 × 7

y + 8 = 5/7 × x + 5

∴ y = 5/7 × x + 5 - 8 = 5/7 × x - 3

y = 5/7 × x - 3

The equation of the line that passes through the point (-7, -8) and parallel to y = 5/7x - 5 is y = 5/7·x - 3.
