Question 2: A. Overlapping lines.

The equations are identical; and if we would treble the first equation, we get the second equation.

Answer:x=-4

Step-by-step explanation:

Answer:

it has two zeroes

it is of the form ax^2+bx+ c

thats all

Step-by-step explanation:

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. ... A parabola intersects its axis of symmetry at a point called the vertex of the parabola.

Answer:

[tex]s = (3 \times 4)2 = 24 \\ s =(3 \times 5)2 = 30 \\ s = (4 \times 5)2 = 40 \\ \\ 24 + 30 + 40 = 94[/tex]

Answer: 28.8 ounces of red paint

Step-by-step explanation:

The total amount of paint created the first time Mango mixed colors was:

= 24 + 16

= 40 ounces of purple color

For 40 ounces of purple, 16 ounces of red was needed. Proportion is therefore:

= 16/40

If one wants 72 ounces of purple therefore:

= Proportion of red used * 72 ounces

= 16/40 * 72

= 28.8 ounces of red paint

Answer:

6

Step-by-step explanation:

The purple shape is dilated by a scale factor of 6.

Hope it helps and is correct!!!

Answer:

Line k

Step-by-step explanation:

The slope is found by rise/run which is change in y/change in x. If you look at a certain few points on line k, you will see it is 3/1 which is 3. The line is going downwards so it is -3.

Answer:

line k

Step-by-step explanation:

Hey There!

So immediately we notice that the slope is negative so we can eliminate line m and line n

So its between line k and j

we notice that it says -3

so the rise over run has to be down 3 over 1

line k shows exactly this

therefore line k is your answer :)

Answer:

b= −3 /50 f+ 27/ 50

f= −50 /3 b+9

Step-by-step explanation:

Let's solve for b.

50b+3f=27

Step 1: Add -3f to both sides.

50b+3f+−3f=27+−3f

50b=−3f+27

Step 2: Divide both sides by 50.

50b /50 = −3f+27 /50 b= −3 /50 f+ 27 /50

Let's solve for f.

50b+3f=27

Step 1: Add -50b to both sides.

50b+3f+−50b=27+−50b

3f=−50b+27

Step 2: Divide both sides by 3.

3f /3 = −50b+27 /3

f= −50 /3 b+9

Step-by-step explanation:

Hello There!

The image shown is a trapezoid

The dimensions of the non shaded area are:

Base 1 = 2 units

Base 2 = 4 units

Height = 3 units

Now that we have found the dimensions we want to solve for the area by using the area formula for a trapezoid

[tex]A=\frac{a+b}{2}h[/tex] where a and b are bases and h is the height

knowing the dimensions all we have to do is plug in the values

so

[tex]A=\frac{2+4}{2} 3\\2+4=6\\\frac{6}{2} =3\\3*3=9\\A=9[/tex]

so we can conclude that the area of the non shaded part is 9 square units

Answer:

The length of a side of the square will b 2/5 cm.

Step-by-step explanation:

To find the area of a 2d object, you need to multiply length and width together. Since it's a square, all the sides are the same length, so that makes it easier. We need to find the square root of 4 and 25. [tex]\sqrt{4}[/tex] is 2, and [tex]\sqrt{25}[/tex] is 5.

Now we need to multiply 2/5 by itself to check. 2/5 x 2/5 = 0.16, or 4/25. The answer is correct. The final result is 2/5. Hope this helped!! :]

The area of a square is the square of one of its side lengths. The length of a side of the square is 2/5 cm

Given:

[tex]Area = \frac{4}{25}cm^2[/tex]

Shape: Square

The area of a square is:

[tex]Area = Length^2[/tex]

So, we have:

[tex]Length^2 = \frac 4{25}cm^2[/tex]

Take positive square roots of both sides

[tex]Length = \sqrt{\frac 4{25}cm^2}[/tex]

[tex]Length = \frac 2{5}cm[/tex]

Hence, the length of the square where the area is [tex]\frac 4{25}cm^2[/tex] is [tex]\frac 2{5}cm[/tex]

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Using the cosine ratio and the exact value

cos45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then

cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{n}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )

2BC = n[tex]\sqrt{2}[/tex] ( divide both sides by 2 )

BC = [tex]\frac{n\sqrt{2} }{2}[/tex] → D
