I need help with solving for y
Answer:
y = [tex]-\frac{5}{3}[/tex] x + 5
Step-by-step explanation:
Solve an equation for a variable mean to leave that variable on one side of that equation by itself.
5x + 3y = 15
5x + 3y - 5x = 15 - 5x
3y = - 5x + 15
[tex]\frac{3y}{3}[/tex] = [tex]\frac{-5x}{3}[/tex] + [tex]\frac{15}{3}[/tex]
y = [tex]-\frac{5}{3}[/tex] x + 5
Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
In 3 min = 4 1/2
10 min = 15
If you multiply both of the snakes speed by the specific amount of minutes and then subtract both of the sums you'll get the answer :)

In a grid of an auditorium, the vertices of a section of seats are A(40, 20) , B(80, 20) , C(100, 70) , and D(40, 70) . The coordinates are measured in feet. Find the area of the section.
Answer:
[tex]Area = 2900[/tex]
Step-by-step explanation:
Given
[tex]A (x_1,y_1) = (40,20)[/tex]
[tex]B (x_2,y_2) = (80,20)[/tex]
[tex]C (x_3,y_3) = (100,70)[/tex]
[tex]D (x_4,y_4) = (40,70)[/tex]
Required
Determine the Area
The area of the section is:
[tex]Area = \frac{1}{2}|(x_1y_2 + x_2y_3 + x_3y_4 + x_4y_1) - (y_1x_2 + y_2x_3 + y_3x_4 + y_4x_1)|[/tex]
Substitute values for the x's and y's
[tex]Area = \frac{1}{2}|(40 * 20 + 80*70 + 100*70 + 40*40) - (20*80 + 20*100 + 70*40 + 70*40)|[/tex]
[tex]Area = \frac{1}{2}|15000 - 9200|[/tex]
[tex]Area = \frac{1}{2}|5800|[/tex]
[tex]Area = \frac{1}{2} * 5800[/tex]
[tex]Area = 2900[/tex]
Hence, the area of the section is 2900ft^2
A function represented by the equation y=1/3x + 4 is a graph on a coordinate plane. What will happen to the line if the slope is changed to 2/3?
Answer:
Graph of the new function will be vertically stretched by 2 units.
Step-by-step explanation:
A linear function is represented by the equation, y = [tex]\frac{1}{3}x+ 4[/tex]
This function has the slope = [tex]\frac{1}{3}[/tex] and y-intercept = 4
If this function is stretched vertically by 'k' the the equation of the new function will be,
y = [tex]a(\frac{1}{3})x+ 4[/tex]
y = [tex]\frac{a}{3}x+4[/tex] ---------(1)
If the slope of this equation is changed to [tex]\frac{2}{3}[/tex],
New equation of the function will be,
y = [tex]\frac{2}{3}x+4[/tex] ---------(2)
Comparing equations (1) and (2),
a = 2
Therefore, graph of the new function will be stretched vertically by 2 units.
Point K is on line segment \overline{JL} JL . Given JK=2x-2,JK=2x−2, KL=x-9,KL=x−9, and JL=2x+8,JL=2x+8, determine the numerical length of \overline{KL}. KL .
Answer:
KL = 10
Step-by-step explanation:
Point K is on line segment \overline{JL} JL . Given
JK=2x−2
JL=2x+8
KL=x-9
JL = JK + KL
Hence:
2x + 8 = 2x - 2 + x - 9
2x + 8 = 2x + x - 2 -9
2x + 8 = 3x - 11
Collect like terms
3x - 2x = 8 + 11
x = 19
We are to find the numerical length of KL
KL = x - 9
KL = 19 - 9
KL = 10

The base of a parallelogram is 6 ft more than the height. If the area of the parallelogram is 55 ft^2, what are the measures of the base and the height?
Answer:
Height = 5 ft
Base = 11 ft
Step-by-step explanation:
The area of a parallelogram is
Base × Height
From the question:
The base of a parallelogram is 6 ft more than the height.
Base = 6ft + h
If the area of the parallelogram is 55 ft^2,
what are the measures of the base and the height?
This is calculated as:
55 ft² =( 6 + h ) × h
55 = 6h + h²
h² + 6h - 55 = 0
h² +5h - 11h - 55 = 0
h(h + 5) - 11(h + 5) = 0
(h + 5)(h - 11) = 0
h - 11 = 0
height = 5ft
Base = 6 + h = 6 + 5
Base = 11ft

The lengths of the sides of a triangle are in the extended ratio 6 : 7 : 10. The perimeter of the triangle is 92 cm. What are the lengths of the sides?
Step-by-step explanation:
[tex] \underline{ \underline{ \text{Given}}} : [/tex]
The ratios of length : 6 : 7 : 10Perimeter of a triangle = 92 cmLet the lengths of a triangle be 6x , 7x and 10x.
[tex] \underline{ \underline{ \text{To \: find}}} : [/tex]
Lengths of the side[tex] \underline{ \boxed{ \text{Sum \: of \: all \: sides \: of \: triangle = Perimeter \: of \: a \: triangle}}}[/tex]
⟹ [tex] \sf{6x + 7x + 10 = 92}[/tex]
Solve for x
⟹ [tex] \sf{23x = 92}[/tex]
⟹ [tex] \sf{ \frac{23x}{23} = \frac{92}{23}} [/tex]
⟹ [tex] \sf{x = 4}[/tex] cm
Now , Replacing the value of x :
⟼ [tex] \sf{6x = 6 \times4 = 24}[/tex] cm
⟼ [tex] \sf{7x = 7 \times 4 = 28}[/tex] cm
⟼ [tex] \sf{10x = 10 \times 4 = 40}[/tex] cm
Hence , the sides of the triangle are 24 cm , 28 cm and 40 cm.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first number be A
Now , the value of A is = 16 cm
Let the second number be = B
The value of B is = 20 cm
The ratio of A and B is calculated as C
where C = A / B
A goes to the numerator of the fraction and B to the denominator
Substituting the values in the equation , we get
