Solve each system by graphing y = -3x - 4,y = 1/2 x + 3

Answers

Answer 1

Answer:

answer is x=-2, y=2

Step-by-step explanation:

y=-3x-4,

y=1/2x+3

now plug in any points for x for both equations. I will plug in both x as 0.

y=-3(0)-4

y=-4

(0,-4)

y=1/2(0)+3

y=3

(0,3)

We have points now to plot on a graph.

Continue what I did. Maybe plug in 1 for x for both equations.

Hope this helps!

Answer 2

Answer:

x= [tex]\frac{-8y -6}{7}[/tex]

Step-by-step explanation:

Step 1: Add (-1)/2x to both sides.

−3x − 4y + [tex]\frac{-1}{2}[/tex] x = [tex]\frac{1}{2}[/tex] x + [tex]\frac{-1 }{2}[/tex] x

Step 2: Add 4y to both sides.

[tex]\frac{-7}{2}[/tex] x - 4y + 4y = 3 + 4y

[tex]\frac{-7}{2}[/tex] x = 4y + 3

Step 3: Divide both sides by (-7)/2.

[tex]\frac{-7 }{2}[/tex] x

      = 4y+3

[tex]\frac{-7}{2}[/tex]        [tex]\frac{-7}{2}[/tex]

Yes, Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50.

What is the reference as the equation?In its most basic form, an equation is an assertion that demonstrates that two formulas are equal. 63x + 5 = 14, for example, is an equation wherein 63x + 5 and 14 are two representations separated by a 'equal' sign.

For the given question;

Let the pounds of dried chili peppers be 'd'.Let pounds of corn husks be 'h'.Chili peppers cost $16.95 per pound Corn husks cost $6.49 per pound.

The equation becomes;

16.95 d + 6.49 h

16.95 (1.5) + 6.49 (3)

  25.425 + 19.47

        44.895 < $50

Thus, Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50.

Alexandra has a home-based business putting on children’s parties. She charges $60 to design the party and then $4.00 per child. Write a function rule that relates the total cost of the party to the number of children n.


f(n) = 4 + 60n

f(n) = 4 – 55n

f(n) = 4n – 55

f(n) = 60 + 4n

Answers

Answer: I don't know/ A. f(n) = 4 + 60n

60+4n=cost. Because the number of children is multiplied by the cost for each child

i would say f(n)=60 +4n but i am probably wrong

Step-by-step explanation: other brainly's

f(n) = 4n + 60...or f(n) = 60 + 4n

f(n)=60+4n that is the correct answer!!!!!!

identify the similar triangles in the diagram, then sketch them so the corresponding sides and angles have the same orientation.

Answers

The triangle KLM and triangle JKM are congruent triangle

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

Triangles that are identical in size and shape are said to be congruent triangles. Inferred from this is that the matching sides and angles are equal. Without checking each of the triangles' sides and angles, we may determine whether two triangles are congruent.

Given a triangle LKJ

We have to find similar triangles in the diagram so the corresponding sides and angles have the same orientation.

By the figure given we can write following things:

LK/LJ = MK/JK

LK/JK = MK/MJ

So the triangle KLM ≅ triangle JKM ≅ triangle JLK

Hence the triangle KLM and triangle JKM are congruent triangle

If x and y vary directly and x=25 when y=100 find x when y=24.
PLEASE HELP FASTTTTTTT

Answers

Answer:

x = 6

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 25 when y = 100 , then

100 = 25k ( divide both sides by 25 )

4 = k

y = 4x ← equation of variation

When y = 24 , then

24 = 4x ( divide both sides by 4 )

6 = x

The bases of a trapezoid lie on the lines y=2X +7 and y= 2X -5. Write the equation that contains the midsegment of the trapezoid

Answers

Given:

The bases of a trapezoid lie on the lines

[tex]y=2x+7[/tex]

[tex]y=2x-5[/tex]

To find:

The equation that contains the midsegment of the trapezoid.

Solution:

The slope intercept form of a line is

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

On comparing [tex]y=2x+7[/tex] with slope intercept form, we get

[tex]m_1=2,b_1=7[/tex]

On comparing [tex]y=2x-5[/tex] with slope intercept form, we get

[tex]m_2=2,b_2=-5[/tex]

The slope of parallel lines are equal and midsegment of a trapezoid is parallel to the bases. So, the slope of the bases line and the midsegment line are equal.

[tex]m=m_1=m_2=2[/tex]

The y-intercept of one base is 7 and y-intercept of second base is -5. The y-intercept of the midsegment is equal to the average of y-intersects of the bases.

[tex]b=\dfrac{b_1+b_2}{2}[/tex]

[tex]b=\dfrac{7-5}{2}[/tex]

[tex]b=\dfrac{2}{2}[/tex]

[tex]b=1[/tex]

So, the y-intercept of the required line is 1.

Putting m=2 and b=1 in slope intercept form, we get

[tex]y=2x+1[/tex]

Therefore, the equation of line that contains the midsegment of the trapezoid is [tex]y=2x+1[/tex].

Answers

Answer:

186.7 cubes

Step-by-step explanation:

How many LaTeX: \frac{1}{3}1 3 inch cubes does it take to fill a box with width LaTeX: 2\frac{2}{3}2 2 3 inches, length LaTeX: 3\frac{1}{3}3 1 3 inches, and height LaTeX: 2\frac{1}{3}2 1 3 inches?

Step 1

We find the volume of the box

= Length × Width × Height

Length = 3 1/3 inches = 10/3 inches

Width = 2 2/3 inches = 8/3 inches

Height = 2 1/3 inches = 7/3 inches

The volume of the box =

10/3 inches × 8/3 inches × 7/3 inches

= 560/9 cubic Inches

= 62 2/9 cubic inches

Step 2

How many 1/3 inch cubes would fill the box.

This is calculated as:= 62 2/9 cubic inches/ 1/3 inches

= 560/9 ÷ 1/3

= 560/9 × 3/1

= 186.66666667 cubes

Approximately = 186.7 cubes

Answers

Answer:

32N

Step-by-step explanation:

Given data

A1= 2cm^2

A2= 16cm^2

F1= 4N

F2=???

Applying the formula

Presure= force/area

P=F/A

F1/A1=F2/A2

substitute

4/2= F2/16

cross multiply

F2= (16*4)/2

F2= 64/2

F2= 32N

Hence the output force is 32N
