Step-by-step explanation:
Step-by-step explanation: To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.

4) Slope = 0 and y-intercept (0, -1)
5) Slope = -1 and y-intercept (0,4)
Type answer here
Find the equation for each slope
Answer:
Step-by-step explanation:
So, lets do the first one.
Slope = 0 and y-intercept is (0, -1)
The y intercept is the second number in the pair because it's the y value
we can switch this to,
y = mx + b
so,
y = 0x - 1
for the first one.
The second one has a slope of -1 and a y intercept of (0,4)
like I said the y intercept is the second number in the coordinate pair,
so,
y = -1x +4
Hope this helps!
Answer:
4.) [tex]y=-1[/tex]
5.) [tex]y=-1x+4[/tex]
Step-by-step explanation:
Use the slope-intercept form for each:
[tex]y=mx+b\\\\m=slope\\\\b=y-intercept\\\\(x,y)[/tex]
The y-intercept happens when x is equal to zero, so when you have the point (0,y), plug in the y-value as the y-intercept.
4.) Insert the appropriate values in the equation:
[tex]y=0x-1[/tex]
Simplify. Any number multiplied by 0 is 0, so:
[tex]y=0+-1\\\\y=-1[/tex]
5.) Insert the appropriate values:
[tex]y=-1x+4[/tex]
This cannot be simplified further.

Persephone is creating a flower garden in her back yard. If she needs 30 pounds of soil per square foot of the flower garden, how much soil will Persephone need to create her garden? Persephone is creating a flower garden in her back yard. If she needs 30 pounds of soil per square foot of the flower garden, how much soil will Persephone need to create her garden? 8 by 19
Answer:
4,560 pounds of soil
Step-by-step explanation:
Ok, based on the information given we are assuming that Persephone's garden is in the shape of a square or rectangle and the measurements 8 by 19 are in feet. That being the case we first need to calculate the square footage of the garden and we do this by multiplying the length by the width like so...
8 ft * 19 ft = 152 sq. ft.
Now that we know the square footage, we calculate how much soil is needed. Since the question states that she needs 30 pounds of soil per square foot then we multiply the square footage of the garden by 30.
152 sq. ft. * 30lb = 4,560lb
Finally, we can see that Persephone will need 4,560 pounds of soil for her garden.

A. 6 degrees
B. 20 degrees
C. 14 degrees
Answer:
20

This equation has no solution.
A non-zero constant never equals zero.
Solving a Single Variable Equation:
5.2 Solve : 2x-3 = 0
Add 3 to both sides of the equation :
2x = 3
Divide both sides of the equation by 2:
x = 3/2 = 1.500
One solution was found :
x = 3/2 = 1.500
Answer:
x = 1.5
Step-by-step explanation:
Step 1: you distribute what is on the outside of the parenthesis to EVERYTHING on the inside of the equation which will leave you with
7x-14-3x+5=-10x+8+4
Step 2: Combine your like terms. You have to add all the X's on the left side first, then your whole numbers. After that, you go to the right side and do the same thing. This should leave you with 4x-9=-10x+12
Step 3: get x to one side of the equation. You do the opposite of what the x is on the right. So you would add 10x on both sides. This should leave you with 14x-9=12
Step 4: You do the opposite of the whole number on the left to both sides/ add 9 to both sides. This should leave you with 14x=21
Step 5: you now divide both sides by 14 because 14x is a multiplication problem, and you need to do the opposite. So you should finally get
X=1.5

which polynomial represents the area of the shaded region with the fewest terms?
Answer:
14x-85
Step-by-step explanation:
The area of the shaded region is
[tex](x + 6)(x - 6) - {(x - 7)}^{2} [/tex]
which if you use the identities to expand it gives you
[tex] {x}^{2} - 36 - {x}^{2} + 14x - 49[/tex]
This then reduces to be

Hey there!
1.no Ans:
The equation of a st.line passing through point (3,0) is;
(y-0) = m1(x-3)........(i)
Another equation is,
y = 2/3x+1...........(ii)
Comparing the equation (ii) with y= mx+c. We get;
Slope (m2)= 2/3
As they are parallel lines, m1=m2.
So, putting value of m1 in equation (i).
[tex]y = \frac{2}{3} (x - 3)[/tex]
[tex]y = \frac{2}{3} x - 3 \times \frac{2}{3} [/tex]
Therefore the required equation is; y = 2/3x -2.
2.Ans:
The equation of a st.line passing through (4,1) is;
(y-1) = m1(x-4)...........(i)
y = -1/2x +2...............(ii)
From equation (ii)
y = -1/2x+2
Comparing the equation with y = mx+c
Slope (m2)= -1/2
As they are equal m1=m2= -1/2
Putting value of slope in equation (i)
[tex](y - 1) = \frac{ - 1}{2} (x + 2)[/tex]
[tex]2(y - 1) = - 1(x + 2)[/tex]
[tex]2y - 2 = - x - 2[/tex]
[tex]x + 2y = 0[/tex]
Therefore the required equation is; x+2y=0.
3. no. Ans:
The equation of a st.line passing through point (-1,-1) is ;
(y+1)= m1(x+1)..........(i)
y= -2x-4.....................(ii)
From equation (ii)
Comparing the equation with y = mx+c.
Slope(m2)= -2
As they are parallel lines, m1=m2 = -2.
Putting value of slope in equation (i)
[tex](y + 1) = - 2(x + 1)[/tex]
[tex]y + 1 = - 2x - 2[/tex]
[tex]2x + y + 3 = 0[/tex]
Therefore the required equation is 2x+y+3=0.
4.no Ans:
The equation of a st.line passing through (-4,-5) is;
(y+5) = m1(x+4)..........(i)
y = -2x-5...............(ii)
From equation (ii)
Comparing the equation with y = mx+c, we get;
Slope (m2)= -2
As they are parallel lines, m1=m2= -2
Putting value of slope in equation (i)
[tex](y + 5) = - 2(x + 4)[/tex]
[tex]y + 5 = - 2x - 8[/tex]
[tex]2x + y + 13 = 0[/tex]
Therefore the required equation is 2x+y+13=0.
5.no Ans:
The equation of a st.line passing through (-4,3) is:
(y-3)= m1(x+4).........(i)
y = 1/2x-3.......(ii)
From equation (ii)
Comparing the equation with y= mx+c.
Slope (m2) = 1/2
As they are parallel lines, m1=m2 = 1/2.
Putting value of slope in equation (i)
[tex](y - 3) = \frac{1}{2} (x + 4)[/tex]
[tex]2(y - 3) = x + 4[/tex]
[tex]2y - 6 = x + 4[/tex]
[tex]x - 2y + 10 = 0[/tex]
Therefore the required equation is; x-2y+10=0.
6.no. Ans;
The equation of a st.line passing through (5,-5) is;
(y+5)= m1(x-5)............(i)
y = -3/2x+2......(ii)
Comparing the equation (ii) with y = mx+c.
Slope(m2)= -3/2.
As they are parallel lines, m1=m2= -3/2.
Putting value of slope in equation (i)
[tex](y + 5) = \frac{ - 3}{2} (x - 5)[/tex]
[tex]2(y + 5) = - 3(x - 5)[/tex]
[tex]2y + 10 = - 3x + 15[/tex]
[tex]3x + 2y - 5 = 0[/tex]
Therefore the required equation is; 3x+2y-5=0.

Is the square root of 8 greater than, less than, or equal to 4 ?
Answer:
√8 is less than 4Step-by-step explanation:
We need to compare √8 and 4
To compare the numbers they should both be in the same format
√8 is not a perfect square so we'll put number 4 under root
4 = √4² = √16Now we compare
√8 < √16So √8 is less than 4

Is K a variable, an equation, a constant, or a formula?
Answer:
Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
