What is the y-intercept for -1,3
Answer:
No solution
Step-by-step explanation:
Luis does not know how old your grandfather Fernando is, but he does know the age of his father john is 20 years younger than him. Luis was 15 years old and was born when his father was 35 years old. Luis uncle is 3 years younger than his dad. Analyze the two equations bellow that represents the ages of the person describe. X+20=y Y-20-3=z what do each variable represents
Answer: X= John's age , Y= Fernando's age, Z = Age of Luis uncle
Step-by-step explanation:
Given: John is 20 years younger than fernando.
i.e. John' age + 20 = Fernando's age
So in the given equation "X+20=Y " , X= John's age and Y= Fernando's age.
From this , John's age: X= Y-20 (i)
Also, Luis uncle is 3 years younger than his dad( John).
Age of Luis uncle = John's age -3
=X-3
= Y-20-3 [From i]
So in the given equation Y-20-3=Z , Z = Age of Luis uncle
are these Equivalent expressions 4(2 + 3) and 4(2) + 4(3)
Answer:
Yes, they are equivalent.
Step-by-step explanation:
To see if they're equivalent, you have to solve them. Start with the first one. Steps are below.Apply the distributed property: 8 + 128 + 12 = 20For second expression:
4(2) = 4 × 2 = 84(3) = 4 × 3 = 12Put them together: 8 + 128 + 12 = 20Making a conclusion:
Because they both have the same answer, they are equivalent expressions.
I hope this helps!
Answer:
40
Step-by-step explanation:
so its simple since the 4(2+3) are in brackets u would put multiply the number in the brakcets for example 2+3 is 5 and that 4 at the side you would multiply it by 4 and you get 20 but then the 4(2) that would just be 4x2 becuase those brackets are singnifieing that its like a multipication problem same with the 4(3) its the same as 4x3 put it all together and you get 40

its suppose to be put into point slope form y=mx+b
Answer:
Slope-intercept is a specific form of linear equations. It has the following general structure. Drum roll ...
\Large y=\maroonC{m}x+\greenE{b}y=mx+by, equals, start color #ed5fa6, m, end color #ed5fa6, x, plus, start color #0d923f, b, end color #0d923f
Here, \maroonC{m}mstart color #ed5fa6, m, end color #ed5fa6 and \greenE{b}bstart color #0d923f, b, end color #0d923f can be any two real numbers. For example, these are linear equations in slope-intercept form:
y=2x+1y=2x+1y, equals, 2, x, plus, 1
y=-3x+2.7y=−3x+2.7y, equals, minus, 3, x, plus, 2, point, 7
y=10-100xy=10−100xy, equals, 10, minus, 100, x [But this equation has x in the last term!]
On the other hand, these linear equations are not in slope-intercept form:
2x+3y=52x+3y=52, x, plus, 3, y, equals, 5
y-3=2(x-1)y−3=2(x−1)y, minus, 3, equals, 2, left parenthesis, x, minus, 1, right parenthesis
x=4y-7x=4y−7x, equals, 4, y, minus, 7
Slope-intercept is the most prominent form of linear equations. Let's dig deeper to learn why this is so.

Answer:
b (-3/5)
Step-by-step explanation:
First, distribute the -2 on the left side
-2x-2=3x+1
now, add 2 to both sides
-2x=3x+3
subtract 3x from both sides
-5x=3
divide both sides by -5
x=-3/5
HTH :)
Answer:
It's b)
Step-by-step explanation:
-2 (x + 1) = 3x + 1
-2x -2 = 3x + 1
-3x +2
-5x = 3
-5x/-5 = x
3/-5 = -0.6
x = - 0.6 (-3/5 as a fraction)

We are given that ∠E and ∠B are right angles and C is the midpoint of AD.
Angle BCA is congruent to Angle DCE (Vertical Angles are Congruent) and Triangle ABC is congruent to DEC (SAS (side-angle-side)).Vertical angles are angles across from each other when two lines intersect. Vertical angles are always congruent. ACB and DEC are a pair of vertical angles, and BCD and ACE are a pair of vertical angles.Side-Angle-Side (SAS) is a congruence shortcut for triangles. When two pairs of congruent sides an one pair of congruent angles (between the sides) are in two triangles, we can assume the triangles are congruent.You are going on a road trip!

Solve for x,
-4/5x -3/20
x + 1/4x = -70
Answer:
x=100
Step-by-step explanation:
Simplify -4/5x-3/20x+1/4x
-7x/10=-70
Multiply both sides of the equation by -10/7.
-10/7*(-7x/10)=-10/7*-70
Simplify both of the equation.
x=100
26 - (2c + 4) = 2(C+6) +C
what is c
Answer:
c = 2
Step-by-step explanation:
26 - (2c + 4) = 2(c+6) + c
26 - 2c + 4 = 2c + 12 + c
26 - 4 - 12 = 2c + 2c + c
10 = 5c
2 = c

Rotated shape in the image
Step-by-step explanation:
Counterclockwise Rotation About the Origin
Given the point (x,y), the counterclockwise rotation about the origin is the point (-y,x), i.e. the coordinates are switched and the y-coordinate is opposed.
The points of the quadrilateral are T(1,-2), S(5,-3), R(5,-4), U(2,-4). The rotated points are:
T'(2,1), S'(3,5), R'(4,5), U'(4,2).
The rotated shape is shown in the image below.

The art club, music club, and drama club at Glendale High School raised money last summer by washing cars.• The art club raised about $3,200 and charged $6 per car.• The music club earned approximately $3,800, charging $8 for each car.• The drama club took in nearly $2,900, at a cost per car of $7. About how many cars did each of the clubs wash?
Answer:
The number of car washed per club is:
The art club = 533 cars
The music club = 633 cars
The drama club = 414 cars
Step-by-step explanation:
The art club, music club, and drama club at Glendale High School raised money last summer by washing cars.•
For the art club
The art club raised about $3,200 and charged $6 per car.•
$6 = 1 car
$3200 = x
6x = 3200
x = 3200/6
x = 533.33333333 cars
Approximately = 533 cars
The music club earned approximately $3,800, charging $8 for each car
$8 = 1 car
$3800 = x
8x = 3800
x = 3800/8
x = 633.33333333 cars
Approximately = 633 cars
The drama club took in nearly $2,900, at a cost per car of $7.
$7= 1 car
$2900 = x
7x = 2900
x = 2900/7
x = 414.28571429 cars
Approximately = 414 cars
The number of car washed per club is:
The art club = 533 cars
The music club = 633 cars
The drama club = 414 cars
A used car has a value of $15,250 when it is purchased in 2012. The value of the car decreases at a rate of 7.5% per year. 1 Write an exponential function that models the value x of the car over y years. 2 To the nearest cent, what will be the value of the car after eight years?
the given P=15250
r=7.5/100=0.075
t=x
y = 15250*(1 - 0.075)^x
after 8 years we would have
x = 8
y = 15250*(1 - 0.075)^8
y = $8,173.42
Answer: after 8 years the value of the car would be $8,173.42

The point does the graph of the line y=2x−6 cross the y-axis will be (0, -6). Then the correct option is C.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given as,
y = 2x - 6
At the y-axis, the value of the variable 'x' becomes zero. Then we have
y = 2 (0) - 6
y = - 6
The point does the graph of the line y=2x−6 cross the y-axis will be (0, -6). Then the correct option is C.
