Emma earns $6 each time she mows the lawn and $8 per hour for babysitting. She is saving up to buy a new pair of jeans that cost $48. If she mows the lawn x times and babysits for y hours, which graph shows the amount of work she needs to complete to earn at least enough to purchase the new jeans?

Answers

Answer 1
Answer: To graph this we find the x- and y-intercepts. The x-intercept would be at 8 and the y-intercept would be at 6.

Explanation:
The equation is 6x+8y=48. An x-intercept is the point where the data crosses the x-axis. All points on this line will have a y-coordinate of 0, so we replace y with 0 and solve:
6x+8(0)=48
6x=48.

Divide both sides by 6:
6x/6=48/6
x=8.
We go to 8 on the x-axis and plot the point.

A y-intercept is the point where the data crosses the y-axis. All points on this line will have an x-coordinate of 9, so we replace x with 0 and solve: 6(0)+8y=48
0+8y=48
8y=48.

Divide both sides by 8:
8y/8 = 48/8
y=6.

We go up to 6 on the y-axis and plot the point. We then draw a line through these two points.
Answer 2
Answer:

Answer:

Refer the figure.

Step-by-step explanation:

Let x be the number of times Emma mows the lawn

and y be the number of hours Emma babysits

Emma earns $6 each time she mows the lawn and $8 per hour for babysitting i.e. 6x+8y

She is saving up to buy a new pair of jeans that cost $48.

i.e. 6x+8y\geq 48

The y-intercept of the line is the point when x=0,

6(0)+8y=48

y=(48)/(8)

y=6

y-intercept is at (0,6)

The x-intercept of the line is the point when y=0,

6x+8(0)=48

x=(48)/(6)

y=8

x-intercept is at (8,0).

The shaded area is determined by putting x and y zero.

6(0)+8(0)\geq 48

0\geq 48

False so the region is away from origin.

The solution is the shade area above the solid line.

Refer the attached figure.

The scatter plot shows the number of stamps Katie collected in different months:. . Plot ordered pairs 1, 30 and 2, 70 and 3, 110 and 4, 150 and 5, 190. . What is the approximate predicted number of stamps she collected in the 25th month?. . A. 980. B.990. C.1000. D.1010

Answers

The sequence:
a 1 = 30,  a 2 = 70,  a 3 = 110,  a 4 = 150,  a 5 = 190,...
a 2 = a 1 + d
70 = 30 + d
d = 70 - 30 = 40
a n = a 1 + ( n - 1 ) * d
For the 25th month:
a 25 =  30 + 24 * 40 = 30 + 960 = 990
Answer: B ) 990.

Answer:

B.) 990

Step-by-step explanation:

Here's another way of looking at it.

Make an equation representing the graph.

y = mx + b

to find m (slope) I used points (1,30) and (4,150) to get 40 as the slope.

y = 40x + b

to solve for b (y-intercept) I plugged in any point that I wanted in the corresponding place in the equation.

using (4,150)

150 = 40 (4) + b

using PEMDAS you find that b = -10

Then plug and chug to find the number of stamps for the 25th term.

y = 40(25) + -10 or y = 40(25) - 10

y = 990

What is f(x)=x2-5 btw that 2 is square

Answers

Answer:

sqrt 5 = 2.23606798

Step-by-step explanation:

Thank you for telling us the 2 is squared that really helps!

x^2 - 5 = 0

(add 5 both sides)

x^2 = 5

(sqrt both sides) (sqrt stands for square root)

x = sqrt 5

(Usally they just want sqrt 5 as an answer but if they want decimals its)

x = 2.23606798

Answer:

x=√(5)

Step-by-step explanation:

f(x)=x^(2)-5

x^(2)-5=0

Add 5 to both sides.

x^(2)=5

To get rid of the square of x, put the square root thingie so that it will cancel out. BTW, if you put it on one side, you have to put it on the other side.

\sqrt{x^(2) }=√(5)

x=√(5)
