solve for x.
4x−5=7+4y
Add 5 to both sides.
4x−5+5=4y+7+5
4x=4y+12
Divide both sides by 4.
4x/4=4y+12/4
x=y+3

Answer:
1 and 2 they both are x=0
Step-by-step explanation:
<em>Note:</em>
<em>Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.</em>
Question 2
Answer:
The equation in the standard form is:
Please also check the attached graph.
Step-by-step explanation:
We know that the equation in the standard form is
Ax + By = C
where x and y are variables and A, B and C are constants
Given
To determine
- Write the equation in the standard form
We know that the slope-intercept form of the line equation
where
In our case:
substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation
y = mx+b
y = -2/3x + (-4)
y = -2/3x - 4
Writing the equation in the standard form
2/3x + y = -4
Therefore, the equation in the standard form is:
Please also check the attached graph.
Answer:
x=24
y=10
z=17
Step-by-step explanation:
These triangles are congruent, which means that the corresponding angles are equal to each other.
Let's start with <em>x</em>. Angle H corresponds to angle N, so we set them equal to each other and slove.
x=24
Next, let's look at z. Angle C corresponds to angle P, so again we set them equal. Z=17.
Finally, we must find y. F and S correspond, but we don't know what the measure of angle S is, but we do know that the interior angles of a triangle add up to 180 degrees, so we solve for angle S and get 115°.
180-(36+115)=29
We now know that angle F equals 29. From solving, we know that Y=10.

Geometry
You need to find the area of the square first.
8x8=64un^2
Then you must find the area for the four triangles.
8x6=42un^2
42un^2/2=21un^2
Then multiply this by four to find the area of all the triangles.
21un^2x4=84un^2
Then add the areas of the triangles and squares.
84un^2+64un^2=148un^2
