Find the slope and the y-intercept of the linear function shown below

Answer:

Souvenir = £14

Burger = £3.50

Pass = £21

Step-by-step explanation:

Souvenir = £x

Burger = [tex]\frac{1}{4}x[/tex]

Pass = [tex]\frac{3}{2}x[/tex]

[tex]\frac{1}{4}x + \frac{3}{2}x +x = 40 - 1.5[/tex]

[tex]\frac{1}{4}x+\frac{6}{4}x+x= 38.5[/tex]

[tex]\frac{11}{4}x = 38.5[/tex]

[tex]11x = 154[/tex]

[tex]x = 14[/tex]

Answer:

5/12

Step-by-step explanation:

1/4 × 60 = 15

He gave 15 cakes to Helen.

He gave 20 cakes to Sue.

20 + 15 = 35

He gave away a total of 35 cakes.

60 - 35 = 25

He has 25 cakes left.

fraction = 25/60 = 5/12

Answer:

c. x < 4

Step-by-step explanation:

-5x < -15x + 40

bring -15x to the left to combine like terms

-5x +15x < -15x + 15x + 40

10x < 40

divided both sides by 10 to get x alone

10x / 10 < 40 / 10

x < 4

Answer:

Step-by-step explanation:

Let X be par.

Jenny made x-1 strokes

Jérôme made x+4 strokes.

So, we can use the amount of strokes made, but we have to use absolute value brackets ( | | )

|-1| + |4| = 5.

Jérôme made 5 more strokes than Jenny

Answer:

11

Step-by-step explanation:

The median is the middle number when they're in ascending or descending order.

In ascending order the numbers are;

5,7,8,9,13,13,15,20

There are two middle numbers, 9 and 13. The median is half-way between the two, which is 11

Answer:

Step-by-step explanation:

Angle one and two lie on straight line.

this means there sum is equal to 180°

Given :-

so we can say :-

[tex] \angle1 + \angle2 = 180 \degree \\ 7x + x + 12 = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{ \cancel{168} {}^{ \: \: 21} }{ \cancel8} \\ x = 21 \degree[/tex]

so angle one = 7x= 7×21 = 147°

angle two = x+12 = 21+12 = 33°

The half-circle is parallel to the other circle so you can find the volume of the circle by itself. Subtract 4 from 3.6 and you should be able to find the heigh of the shape between the half circles. Multiply the Circular Slab of 3.6 by 0.4. Which gives you 1.44. (Do not take this as an answer, i tried but i dont think this was a great explanation)

Answer:

[tex]x=-6; y=4[/tex]

Step-by-step explanation:

Step 0: retwite the second equation by dividing LHS and RHS by 3.

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

Step 1: combine them as the first minus twice the second to eliminate y

[tex]I - 2\times II : 5x+4y -2x-4y=-14-4 \rightarrow 3x=-18 \rightarrow x= -6[/tex]

Step 2a: At this point I would replace the value of x in the second equation to easily solve for y.  That will give you [tex]-6+2y=2 \rightarrow y=4[/tex]. I do imagine you're required to use the same method to solve for y even if it's slower so...

Step 2b: Combine them again, taking the first minus 5 times the second to eliminate x:

[tex]I-5II: 5x+4y-5x-10y=-14-10 \rightarrow -6y=-24 \rightarrow y=4[/tex]

Answer:

x = 59

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] x = 14 [tex]\frac{3}{4}[/tex] ← convert to improper fraction

[tex]\frac{1}{4}[/tex] x = [tex]\frac{59}{4}[/tex] ( multiply both sides by 4 to clear the fractions )

x = 59

Answer:

44 degrees

Step-by-step explanation:

angle c = 90 degrees

angle a = 46 degrees

the measure of all sides on a triangle is 180

so to solve for the other side we can do this equation...

180 - (90 + 46) = 44

hope this helped, mark as brainliest pls

Answer:

n + 50 = 90; n = 40

Step-by-step explanation:

the angle is a right angle so it adds up to 50

one side is 50

so

n + 50 = 90

subtract 50 to both sides

n = 40

Step-by-step explanation:

We want to get g(x) given that we know f(x) and the graphs for both functions. We will see that the correct option is D:

g(x) = (x/3)^2

By looking at the graph we can see that f(x) and g(x) are two quadratic functions, and g(x) is just a dilation of f(x).

This means that:

g(x) = A*f(x)

Where A is a real number.

We know that:

f(x) = x^2

And by looking at the graph, we also know that g(3) = 1.

Then we can write:

g(3) = A*f(3) = A*3^2 = 1

Now we can solve this for A:

A*3^2 = 1

A*9 = 1

A = 1/9

Then we have:

g(x) = (1/9)*f(x) = (1/9)*x^2 = (x/3)^2

So the correct option is D.

Answer: What is the easiest way to find the volume of a sphere?

Image result for How to find volume of sphere explain step by step

To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don't have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.
