PLS HELP

Answers

Answer:

The slope of f(x) is equal to the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).

Step-by-step explanation:

F(x) is already given to you on the graph. You need to plot the x and g(x) graph. (remember g(x) is just a fancy way of saying y)

Once this line is plotted, you will see that f(x) and g(x) are parallel to one another. G(x) is below f(x), so its y-intercept is lower.

Solve the simultaneous equations 2x + y = 5 and 2y = x – 10.

Answers

x = 4
The first equation can be substituted into the second one. It would be: 2(-2x+5)=x-10 and after solving it, x = 4

[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]

The given equations are :

[tex]2x + y = 5[/tex]

[tex]2y = x - 10[/tex]

From the first equation, we get :

[tex]2x + y = 5[/tex]

[tex]y = 5 - 2x[/tex]

now, let's put the value of y as (5 - 2x) in second equation to find the value of x :

[tex]2y = x - 10[/tex]

[tex]2(5 - 2x) = x - 10[/tex]

[tex]10 - 4x = x - 10[/tex]

[tex]5x = 20[/tex]

[tex]x = 4[/tex]

hence, value of x = 4, Plugging the value of x in second equation :

[tex]2y = x - 10[/tex]

[tex]2y = 4 - 10[/tex]

[tex]2y = - 6[/tex]

[tex]y = - 3[/tex]

so, the required values are :

x = 4

y = -3


Jake earns $8 per hour for cutting grass. If he works a 35-hour week,
how much money will he earn?

Answers

There are many ways to solve these types of questions. But I am going to use the fraction method.

Step 1: Set up a fraction.

Setting up a fraction, given the question will be the units on the same level. And the money earned will be a variable, "[tex]m[/tex]". It does not matter whether they are top or bottom.

[tex]\frac{8}{1} = \frac{m}{35}[/tex]

Step 2: Solve

[tex]\frac{8}{1} = \frac{m}{35}[/tex]

Multiply 35 to both sides

[tex]\frac{35m}{35}=8\cdot \:35[/tex]

[tex]m=280[/tex]

Therefore, Jake will earn $280.

These are not constant, so the relation is not linear.

Second differences are ...

 360, 360

These are constant, so the relation is quadratic. With a short trial, we find that a suitable equation is ...

Find the average speed in km/h for a journey of 175 meters and 35 seconds

Answers

Answer:

18 km/h

Step-by-step explanation:

1. Convert 175 metres into km

1000 m = 1 km (divide by 1000)

175 ÷ 1000 = 0.175 km

so 175 m = 0.175 km

2. Convert 35 seconds into hours

60 seconds = 1 min

60 mins = 1 hour

3600 (60 × 60) seconds = 1 hour (divide by 3600)

35 ÷ 3600 = 0.00972...

3. Calculate the speed

speed = distance ÷ time

= 0.175 ÷ 0.00972...

= 18 km/h

help please this is timed i’m not sure if my answer is correct
(it’s abt perpendicular, parallel and skew lines)

Answers

Answer:

Perpendicular

Step-by-step explanation:

Both lines intersect and form a right angle when they intersected each other. Non co-planar means essentially means "on different planes", but both lines do lie on the same plane. Parallel lines don't intersect at all! However lines a and d are intersecting. Skewed means neither parallel nor perpendicular (meaning they intersect and don't form a right angle).

Answer:

It would be perpendicular.

Step-by-step explanation:

Perpendicular lines form a 90-degree angle.

Skew lines are on different planes and do not intersect.

Since A and D intersect with a 90-degree angle they're perpendicular.

The money he will make over a five-month period will be $7,500.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A rec center worker procures a similar sum every month. In the wake of laboring for a considerable length of time, he procured $4,500.

The amount of money that he earns each month is given as,

⇒ $4,500 / 3

⇒ $1,500 per month

Then the money he will make over a five-month period will be given as,

⇒ $1,500 x 5

⇒ $7,500

The money he will make over a five-month period will be $7,500.

Find the x- and y-intercepts of : 4y-6x = 24

Answers

Answer:

x-intercept: (-4, 0)

y-intercept: (0, 6)

Step-by-step explanation:

4y - 6x = 24

To find the x-intercept, set the y value equal to 0.

4(0) - 6x = 24

Simplify by removing 4(0) since it just equals 0.

-6x = 24

Divide both sides of the equation by -6

x = -4

Since we set y equal to 0 and we know that the x value is -4, we can create a coordinate for the x-intercept of the equation.

(x, y) = (-4, 0)

Repeat the process for finding the y-intercept, but set x equal to 0.

4y - 6(0) = 24

4y - 0 = 24

4y = 24

Divide both sides of the equation by 4

y = 6

Write as a coordinate/intercept.

(x, y) = (0, 6)
