Answer:
Y=-2x+9
Step-by-step explanation:
The first thing is to know the formula which is Y÷x
Then... The line (1,7)use the coordinates Y and X so it will be as follows... Label 1 and 7 as x, y
So it will be Y-7÷X-1 = the gradient which is - 2
So multiply both sides by X-1
So it will be Y-7=2x+2 again be careful because a negative number multiplied by another negative will give you a positive sign
Remember Y-7....... Take 7 to the other side so it will be a positive...... Then work out the integers

Use a proportion to find the missing side length in the following similar figures. Please help me understand and figure out how to solve this question. Thank You! :)
Answer:
x = 4.5 m ⇒ A
Step-by-step explanation:
The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal
In the given figure
∵ The two triangles are similar
∵ 2 m and x are corresponding sides
∵ 4 m and 9 m are corresponding sides
∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]
→ By using cross multiplication
∴ x × 4 = 2 × 9
∴ 4x = 18
→ Divide both sides by 4 to find x
∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]
∴ x = 4.5 m

4.5m they are correct

Write the component form of the vector that translates P(4,5) to P'(-3,7)
Answer:
The component form of the vector is v = -7·i + 2·j
Step-by-step explanation:
The given parameters are;
The coordinates of the initial point = P(4, 5)
The coordinates of the point after the translation by the vector, v = P'(-3, 7)
Therefore, we have;
The horizontal component of the vector, vₓ = (-3) - 4 = -7
The vertical component of the vector, [tex]v_y[/tex] = 7 - 5 = 2
The magnitude of the translation, v = √([tex]v_y[/tex]² + vₓ²) = √((-7)² + 2²) = √53 ≈ 7.28
Therefore, the component form of the vector, v, is given as follows;
v = vₓ·i + [tex]v_y[/tex]·j
Substituting the known values of vₓ and [tex]v_y[/tex] gives;
v = -7·i + 2·j
The component form of the vector is v = -7·i + 2·j.

Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.
Quadrilateral A B C D is translated down and to the left to form quadrilateral O L M N.
If AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units, what is LO?
5 units
6 units
8 units
10 units
Answer:
LO = 6 units ⇒ B
Step-by-step explanation:
Translation does not change the size or the shape of the figure
∵ Quadrilateral ABCD is translated down and left to form
quadrilateral OLMN
∴ The image of side AB is side OL
∴ The image of side BC is side LM
∴ The image of side CD is side MN
∴ The image of side AD is side ON
∵ AB = 6 units
∵ Translation does not change the size of the figure
∴ The image of AB = 6 units
∵ The image of AB is OL
∴ The length of OL = 6 units
∵ OL = LO
∴ LO = 6 units
The length of LO of the newly translated quadrilateral is; Option B: LO = 6 units.
Translation of objects in mathematics simply means to move an object from one point to another without a change of length or figure.
Now we are told that Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.
Thus means Quadrilateral OLMN is still same size and length as ABCD and as such the sides will correspond in order.
Thus, it means that;
AB = OL
BC = LM
CD = MN
AD = ON
We are given;AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units
Thus, since AB = OL, we can say that;
LO = 6 units.

A daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month. Her goal is to have a larger staff, including an equal number of assistant caregivers and senior caregivers. How long will that take? How many of each type will there be?
After _____months, there will be_______ of each type of caregiver
After 3 months, there will be 12 of each type of caregiver
How to illustrate the equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.
Since the daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month.
This will be:
9 + m = 6 + 2m
where m= number of months
Collect the like terms
2m - m = 9 - 6
m = 3
The number of caregiver will be:
9 + m
9 + 3
= 12

Tony’s class needs more than $500 for the school dance. So far, they have raised $200. They plan to have a car wash, charging $8 a car, to raise more money. Tony solved the inequality 8x + 200 Greater-than-or-equal-to 500, and determined that if they wash 37 cars, they will have enough money. Is he correct? Explain.
Answer:
No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5. Since the class must wash a whole number of cars, they need to wash at least 38 cars.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given table is
x 0 2 3 4
y -2 0 1 2
The slope is m=2-4/1-3=-2/-2=1
m=1
y intercept is 2=4+b
b=-2

Jordan signed up for the Annual Cross Florida bike ride which is a 170 mile bike ride. After weeks of training he rides at an average of 15 miles per hour. What is x in real world context?
Answer: 11.3 hours
Step-by-step explanation:
Before this question is another asking for an equation depicting this with Jordan's progress in miles (y) after a number of hours (x).
That would be y = 15x
x in the real world context would be the number of hours it would take for Jordan to finish the 170 mile bike race.
To solve this make y to be 170 and solve for x.
170 = 15x
x = 170/15
x = 11.3 hours

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!
