Write a number sentence and determine the sum for the shown model.

Answer:

3x-x+2=4

Step-by-step explanation:

You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.

Answer:

y = 3/4x + 5

-3x + 4y = 20

Step-by-step explanation:

In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)

First change that standard form equation to slope-intercept form:

1. 4x + 3y = 8

2. 3y = -4x + 8

3. y = -4/3x + 8/3

Step 1 is given.

In step 2, 4x was subtracted from both sides.

In step 3, both sides were divided by 3.

Slope-intercept form:

y = mx + b

m is the slope and b is the y-intercept.

m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)

b = 5; the y-intercept was stated in the problem

Now, you put it together: y = 3/4x + 5

Standard form:

You can just change the slope intercept form back into standard form by moving the numbers around a bit:

1. y = 3/4x + 5

2. -3/4x + y = 5

3. -3x + 4y = 20

Step 1 is given.

In step 2, 3/4x was subtracted from both sides of the equation.

In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)

Step-by-step explanation:

In this question as two straight lines intersect each other

we use vertically opposite angle axiom

so 74 degree = 2x.

then x= 74/2= 37degree

Answer:

Angle 74 degrees and 2x are vertical, so they would have to equal each other.

Note: Vertical angles are congruent meaning they measure the same degrees

So we set up the equation;

74 = 2x

/2     /2

37° = x

Answer:

As the time went by the shadow got smaller untill it hit three pm and 4pm. The reason the box shadow did not change over the time period of 4pm and 7pm is because at night there is no chance of light hitting around the box because from this graph I can see that the sun was goung down by 3pm. In conclusion the graph below shows when the sun was up and when the sun went down.

Answer:

distance: 14

explanation:

[tex]\sf \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

given:

solve:

[tex]\sf \rightarrow \sqrt{(5-5)^2+(6--8)^2}[/tex]

[tex]\sf \rightarrow \sqrt{(0)^2+(14)^2}[/tex]

[tex]\sf \rightarrow \sqrt{14^2}[/tex]

[tex]\sf \rightarrow 14[/tex]

Solution:

We know that:

[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]

Finding the coordinates

Substitute the coordinates into the distance formula.

[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]

[tex]\rightarrow \text{Distance }=\sqrt{[(6- (-8)]^{2} +[5-5]^{2}}[/tex]

[tex]\rightarrow \text{Distance }=\sqrt{[(6 + 8]^{2} +[0]^{2}}[/tex]

[tex]\rightarrow \text{Distance }=\sqrt{[14]^{2}[/tex]

[tex]\rightarrow \boxed{\text{Distance }=14 \ \text{units}}[/tex]

Step-by-step explanation:

The amount of food her dog eat per day would be; 0.33 pound.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that  Debbie’s dog eats 21/5 pounds of dog food every 14 days.  Debbie’s dog eats the same amount of food each day.

Therefore,

21/5 pounds of dog food = 14 day

one day = 14 / (21/5 ) pounds of dog food

One day = 14 x 5/ 21

= 10/3

Therefore, the amount of food her dog eat per day would be; 0.33 pound.
