Which equation has both 3 and -3 as possible values of y ?
Answer:
[tex] {y}^{2} - 9 = 0[/tex]
Step-by-step explanation:
as both 3 and - 3 are possible values of y;
[tex]y = 3 \: or \: y = - 3[/tex]
[tex]y - 3 = 0 \: or \: y + 3 = 0[/tex]
therefore;
[tex](y - 3)(y + 3) = 0[/tex]
by expanding;
[tex] {y}^{2} - {3}^{2} = 0[/tex]
[tex] {y }^{2} - 9 = 0[/tex]

Step-by-step explanation:
the top angle is a eight angle which is equal to 90 all triangles are 180 degrees both bottom angles are equal and 180 minus the 90 degree from the right angle is 90 degrees you divide that by 2 and you have your answer
Sophie used the equation y = x + 1 to represent that the length of a piece of fabric needed for a craft project (y) is always 1 inch greater than the length of the object made with the fabric (x). Which graph represents four solutions to Sophie's equation?
Answer: Last graph, the one with the points (1, 2), (2, 3), (3, 4), and (4, 5)
Step-by-step explanation:
We have the equation y = x + 1
Now we can replace x by different values to get pairs (x, y).
if x = 1, we have:
y = 1 + 1 = 2
then we have the pair (1, 2)
if we have x = 2, then:
y = 2 + 1 = 3
Then we have the pair (2, 3)
So we need to find the graph that has these points.
The only graph that has the points (1, 2) and (2, 3) is the last graph.
Pls, help. Whichever one you want, but whoever does all of them first I will give them the brainiest.

Can someone help me?
Need to show the work
Answer:
AB = [tex]\frac{108}{7}[/tex]
Step-by-step explanation:
Δ ALM and Δ ACB are similar, then the ratios of corresponding sides are equal, that is
[tex]\frac{AM}{AB}[/tex] = [tex]\frac{AL}{AC}[/tex] , substitute values
[tex]\frac{12}{AB}[/tex] = [tex]\frac{14}{18}[/tex] = [tex]\frac{7}{9}[/tex] ( cross- multiply )
7AB = 108 ( divide both sides by 7 )
AB = [tex]\frac{108}{7}[/tex] ( = 15 [tex]\frac{3}{7}[/tex] )

Answer:
a. y = 3x + 4.5 & y = 7x + 2
b. x = 0.625 (year)
c. 6.375 feet
Explanation:
Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x
type A grow 3 inches per year = 3x
type B grows 7 inches per year = 7x
y = the total height
Since they both equal to y, you can set them equal to each other
3x + 4.5 = 7x +2
After solve you get answer for b
Work: 3x + 4.5 = 7x + 2
4.5 = 4x + 2
2.5 = 4x
0.625 = x
Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height

(PLEASE) Triangle IJK is similar to triangle LMN. Find the measure of side MN. Round your answer to the nearest tenth if necessary. Figures are not drawn to scale.
Answer:
MN = 126.31Step-by-step explanation:
ΔIJK = ΔLMN --- (given)
So,-----------------------
KI / KJ = NL / MN
19 / 40 = 60 / MN
MN = 60 × 40 / 19
MN = 126.31
The required measure of side MN will be 126.3 units.
What are Similar Triangles?Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides. The triangles that like one another but may not be exactly the same size are said to be similar triangles.
Given that triangle ΔIJK ~ ΔLMN in the question.
We know that Similar triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
As per the similarity rule of triangles, we can write the ratio as:
⇒ KI / KJ = NL / MN
⇒ 19 / 40 = 60 / MN
⇒ MN = 60 × 40 / 19
⇒ MN = 126.3157
Rounded to the nearest tenth to get
⇒ MN = 126.3

James was saving his money to buy a new bicycle. The bicycle originally costs $150 but then the store owner marked up its price by 20%. What is the new cost of the bicycle
Answer:
$180
Step-by-step explanation:
To find the new cost, multiply the original cost by 1.2
150(1.2)
= 180
So, the new cost of the bicycle is $180
Answer:
180

A stack of one dozen cookies of diameter
5 in. exactly fits in a cylindrical container of
volume 179.715 in.3. Which is the thickness of
each cookie?
Answer:
.763 in for each cookie
Step-by-step explanation:
[tex]179.715 =\pi (2.5)^{2} h\\179.715= \pi (6.25)h\\179.715=19.635h\\h=9.153\\[/tex]
After you solve for the height you would divide it by 12 to get the thickness of one cookie which is .763 in.
A trapezoid with an area of 36 inches squared.
What is the area of the enlarged trapezoid?
54 in.²
81 in.²
576 in.²
864 in.²
Answer:
B. 81 in.²
Step-by-step explanation:
We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.
The area of the original trapezoid is 36 square inches.
Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.
The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.
1.5 × 1.5 = 2.25
Area of new trapezoid: 2.25 × 36 in²
Area of new trapezoid = 81 in²
The area of the enlarged trapezoid would be 81 in² or option B.
