The total number of people in the city surveyed by Annette= 480 people.

Step-by-step explanation:

Let 'X' be the Total Number of people Annette surveyed.

Out of Total people in the city, only <u>180 people are not interested</u> in a new shopping mall.

Therefore, it is given in the question that <u>180 is 37.5% of Total number of people surveyed (X).</u>

step 1: 180= (37.5/100)*(X)

step 2: X= (180*100)/37.5

step 3: X= 18000/37.5

step 4: X= 480

Determine the slope and y -intercept for each line shown. Then write the equation of the line (will give Brainliest)
Pavlova-9 [17]

Answer:

1.

y=\frac{1}{4}x+2

m= \frac{1}{4}

b= 2

2.

y=-\frac{1}{3}x+1

m= -\frac{1}{3}

b= 1

3.

y=3x+4

m= 3

b=4

Step-by-step explanation:

1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.

The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that y=\frac{1}{4}x+2

2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.

The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that    y=-\frac{1}{3}x+1

3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.

The line rises up 3 units on the y-axis for every 1 unit on the x-axis therefore the line has a slope of m=3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that  y=3x+4

when Apple sells their iPads they increase the price $50 from what it cost then to actually make the iPads one Apple Store sold
Anvisha [2.4K]
First things you have to do is figure out how much they increased the iPads by:

$50 • 10 = $500

They increased the iPad price by $500.

Subtract the total amount from the iPad price:

$5,000 - $500 = $4,500

The actual price of 10 iPads, without an increase is $4,500

Now divide that by 10 to get the amount for one iPad:

$4,500 ÷ 10 = $450

One iPad actually costs $450 to make.

How many times does the graph of the function below interect or touch the x-axis? y=-2x^2+3x+5
Andrei [34K]

Answer:

Two times at (-1,0) and (2.5,0)

Step-by-step explanation:

When the graph intersects or touches x-axis, y is equal to 0

so y = -2x^2 + 3x + 5

=> 0 = -2x^2 + 3x + 5

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

so a = -2

    b = 3

    c = 5

substitute in the formula

x = [-3 +/- √(3^2 - 4x-2x5)]/2(-2)

x = [-3 +/- √(9 + 40)]/(-4)

x = [-3 +/- 7]/(-4)

x1 = (-3 + 7)/(-4) = 4/-4 = -1

x2 = (-3 - 7)/(-4) = -10/-4 = 5/2 = 2.5

so the graph has two x-intercepts (-1,0) and (2.5,0), therefore it intersects x-axis two times
