Answer 1
Answer:

Answer:

A (y= 5/2x-7)

Step-by-step explanation:

For slope: plug variables into slope equation (y1-y2/x1-x2) to get -2-(-7)/2-0= 5/2

The y-intercept (y value where x=0) is already given= -7

Plug slope and y-intercept into slope intercept equation (y=mx+b) where m=slope and b= y-intercept to get the equation y=5/2x -7

This graph shows the costs of purchasing two types of bird seed mix. Which statement is true? Seed Mix A is more expensive than Seed Mix B. Seed Mix B is more expensive than Seed Mix A. Seed Mix A and Seed Mix B cost about the same. A graph measuring cost and bags. Two lines, labeled Seed Mix A and Seed Mix B, exit the origin to show that cost increases as bags increases

Answers

Answer:

seed Mix A is more expensive than Seed Mix B.

Step-by-step explanation:

The graph of Mix A is above the graph of Mix B.

Looking at the labels of the graphs, we see that the x-axis represents the number of bags bought and the y-axis represents the cost.

For every point along the x-axis, Mix A's cost is above Mix B's cost.  This means that Mix A is more expensive.Step-by-step explanation:

Consider the quadratic equation y = –3x2 – 2x + 4.  A. Find the value of the discriminant.  B. How many real roots does the equation have?  C. Does the vertex of the graph of the equation lie above, on, or below the x-axis?  

Answers

A. discriminant = 52;
B. 2, because 52 > 0
C. - discrminant / 4a = -52 / -12 = 6 > 0 =>  the vertex of the graph of the equation lie above the x-axis.

The solution to x - 8 > - 3

Answers

Answer: x > 5

Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation, to get x by itself on one side.

Since 8 is being subtracted from x, add

8 to both sides of the inequality.

On the left the -8 +8 cancels out

and on the right, -3 + 8 is 5.

So we have x > 5.

Answers


u need two equations.x + y = 125
0.60x + 0.30y = (0.36)(125)

x + y = 125
0.60x + 0.30y = 45

solve for a variable in the first equation
y = 125 - x

plug into the second equation
0.60x + 0.30(125 - x) = 45
0.60x + 37.5 - 0.30x= 45
0.30x + 37.5 = 45
0.30x = 7.5
x = 25

plug the answer for x into the first equation
25 + y = 125
y = 100
