Answers

Answer 1

Answer:

4(y+2) = 3(x+4) and 4y - 3x = 4

Step-by-step explanation:

The equation of the line in point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given the equation 3x - 4y = 7

Rewrite in slope intercept form

-4y = -3x+7

y = 3/4 x - 7/4

Slope = 3/4

Slope of the required line will also be 3/4  since they are parallel lines

Substitute the slope and the point into the equation above;

y - y0 = m(x-x0)

y +2 = 3/4 (x+4)

4(y+2) = 3(x+4)

4y + 8 = 3x+12

4y - 3x = 12-8

4y - 3x = 4

Hence the required equations are 4(y+2) = 3(x+4) and 4y - 3x = 4

2)what is the ratio of 400m to 1.5km​

Answers

Answer:

4km/1.5km

Step-by-step explanation:

hope that helps :)

Ratio of 400m to 1.5km​ is 400/1500 or 400:1500

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Here the given quantities are 400m and 1.5km

The quantities are with different unit

We convert them into same unit

We know that one kilometre=1000 metre

One kilometre equal to thousand metres.

Let us convert 1.5 km to metre by multiplying 1.5 with 1000

1.5×1000=1500

The ratio of 400m to 1.5km​ is 400/1500 or 400:1500

Hence  ratio of 400m to 1.5km​ is 400/1500 or 400:1500

Answer:

2 [tex]\frac{1}{2}[/tex]pizzas

Step-by-step explanation:

The equation to this question can be written as 5/6 + 5/6 + 5/6 or 5/6 x 3.

To multiply 5/6 by 3, we can set it up as [tex]\frac{5}{6} * \frac{3}{1}[/tex]. Now to multiple, we just multiply straight across. We do 5 * 3 over 6 * 1 to get 15/6. Now, all we have to do is simplify the fraction. 6 goes into 15 two times, so we know they ate 2 pizzas. Now we are left with 3/6. 3/6 can be rewritten as [tex]\frac{1}{2}[/tex]. In total, they ate 2 [tex]\frac{1}{2}[/tex] pizzas.

You buy a total of 50 turkey burgers and veggie burgers for $90. You pay $2 per
turkey burger and $1.50
per veggie burger. WRITE and SOLVE a system of
linear equations to find the number y of veggie burgers that you buy.

Answers

Answer: There are 20 veggie burgers.

There are two ways you can solve this:

Let x represent turkey burger and y for veggie burger.

2x + 1.50y = 90
x + y = 50

Work:
-2(x + y = 50)
-2x + -2y = -100

2x + 1.50y = 90 << Add like terms
+ -2x + -2y = -100
______________
-0.50y = -10 << Solve for y
y = 20

____________________________

Let x represent turkey burger and y for veggie burger.

2x + 1.50y = 90
x + y = 50 << Solve for x

x = 50 - y << Plug in y for 2x + 1.50y = 90

2(50 - y) + 1.50y = 90
100 - 2y + 1.50y = 90
-0.50y = -10
y = 20




The number of 20 veggie burger, you bought.

What is the system of equations?

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

You buy a total of 50 turkey burgers and veggie burgers for $90.

You pay $2 per turkey burger and $1.50 per veggie burger.

Let x represents the turkey burger and y represents the veggie burger.

So, the system of equations,

x + y = 50   equation 1

2x + 1.5y = 90    equation 2

Substituting the value of x from the equation 1 to the equation 2,

100 - 2y + 1.5y = 90

y = 20

Then x = 30

Therefore, 20 veggie burgers you bought.

Step-by-step explanation:

Solve the equation.

[tex] {x}^{2} - 9 = 0[/tex]

Use the difference of two squares formula.

[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]

[tex](x + 3)(x - 3) = 0 \\ x = 3, - 3[/tex]

Second Screenshot

A linear relationship already says it all. Find the graph that is NOT a curve. The only image that is not a curve and the graph straight forwards is the Image C aka A choice.

Third Screenshot

A nonlinear function is a function that does not have a straight line graph. All linear functions are linear, except for Quadratic and up. Every polynomial function with the degree greater than one wont be a linear.

Fourth Screenshot

[tex]y = x + 3[/tex]

If we change the constant from 3 to 5 then we would get

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

The graph would shift up 2 units.

Last Screenshot

The second and third graph both are function. We can tell by doing a line test. Simply draw a vertical line first. Then we check if the line intercepts the graph more than a point or not.

If the line intercepts more than a point then it is not a function.

If the line intercepts only a point then it is a function.

Right Triangles

In a right triangle, there is an internal angle of 90°. The other two must add up to 90°.

The trigonometric ratios are satisfied in a right triangle. The tangent ratio, for example, is defined as:

[tex]\displaystyle \tan 35^\circ=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

The angle of 35° is adjacent to the side of length 18 and is opposite to the side of length x, thus:

[tex]\displaystyle \tan 35^\circ=\frac{x}{18}[/tex]

Solving for x:

[tex]x=18\tan 35^\circ[/tex]

This is the equation to solve. Now substitute the tangent for its value to get
