Answer:

first subtract the 2 cancelling out on the left side, making the -3 a -5, then add y cancelling out the left side, making the right side -5+y, than your equation is 5x=-5+y, dividing the 5 off makes x=-5+y/5. :)

A frozen pizza cost $3.00 in the year 2000. In 2015, it cost $2.50. What is the percent of change of the pizza from 2000 to 2015

UkoKoshka [18]

Answer:

Step-by-step explanation:

Increased amount = 3 - 2.50 = $ 0.50

Increase percentage = $\frac{0.50}{2.50}*100\\$

= 5 *4

= 20%

Two sidewalks in a park are represented by lines on a coordinate grid. Two points on each of the lines are shown in the tables.

algol [13]

Answer:

y = 2x + 1 ;

y - 3 = - 3(x - 1) ; y = - 3x + 6 ;

Independent ;

(1, 3)

Step-by-step explanation:

Given the data:

Sidewalk 1:

x __ y

2 _ 5

0 _ 1

Sidewalk 2:

x __ y

1 _ 3

3 _ -3

Equation for sidewalk 1 in slope - intercept form:

Slope intercept form:

y = mx + c

c = intercept ; m = slope

m = (change in y / change in x)

m = (1 - 5) / (0 - 2) = - 4 / - 2 = 2

Y intercept ; value of y when x = 0

(0, 1) ; y = 1

Hence, c = 1

y = 2x + 1

Sidewalk 2:

Point slope form:

y - y1 = m(x - x1)

m = slope

m = = (-3 - 3) / (3 - 1) = - 6/2 = - 3

Point (x1, y1) = (1, 3)

y - 3 = - 3(x - 1)

To slope intercept form:

y - 3 = - 3(x - 1)

y - 3 = - 3x + 3

y = - 3x + 3 + 3

y = - 3x + 6

Since the slope of both lines are different, intersection will be at single point and will have a single solution. This makes it independent.

Using substitution method :

y = 2x + 1 - - - (1)

y = - 3x + 6 - - - (2)

Substitute (1) into (2)

2x + 1 = - 3x + 6

2x + 3x = 6 - 1

5x = 5

x = 1

From (1)

y = 2(1) + 1

y = 2 + 1

y = 3

Coordinate of the point of intersection = (1, 3)

What does b do in y=ax^2+bx+c. How can b being positive or negative affect a graph?

Dmitry_Shevchenko [17]

Answer:

The positions of the vertex and the axis of symmetry change.

Step-by-step explanation:

Let’s examine three parabolas in which a and c remain constant and only b changes.

(1) y = x² - 2x + 1

(2) y = x² + 1

(3) y = x² + 2x + 1

In the image below,

Equation (1) is the black parabola, Equation (2) is green, and Equation (3) is red.

When b is more negative, the vertex moves down, and the axis of symmetry moves to the right.

When b is more positive, the vertex moves down, and the axis of symmetry moves to the left.

Find the value of y in the right triangle below. A. 40 B. 90 C. 30 D. 50

zhannawk [14.2K]

Answer:

A. 50

Step-by-step explanation:

Sum of interior angles of a triangle is always =180 °

Since this is a right triangle, therefore we know that one angle of the triangle measures 90°

Therefor sum of other two angles has to be = $180\°-90\°=90\°$

One angle measures = 40°

Therefore the missing angle $y=90\°-40\°=50\°$

$y=50\°$
