could someone help? which graph correctly represents the equation? i’ll mark brainliest

Answer:

Step-by-step explanation:

When two angles add to 90°

Answer:

y = 0.5x-7

Step-by-step explanation:

First we need to find the slope so we use the formula y2 - y1 / x2 - x1 = m

The variable m will represent the slope or rate of change

-2 - (-11) / 10 - (-8) = m

Or

-2 + 11 / 10+8 = m

9/18 = m

0.5 = m

y = 0.5x+b

To find b replace the y and x variables

I will use 10 and -2

-2 = 0.5(10)+b

You should come out with -7 = b

Answer:

3 shirt=3×$18.75

=56.25

2 pair shocks =3.99×2

=8

1 pair slacks=45.00

total=109.25

tax=6.75% then;

109.25+6.25%×109.25

109.25+6.25/100×109.25

109.25+0.0625×109.25

109.25+6.28

116.07

Answer:

Akash walked [tex]1\frac{4}{15}[/tex] kilometers in all.

Step-by-step explanation:

Given that:

Distance covered while walking to school = 2/3 km

Distance covered while walking back = 3/5 km

We will add the distance.

Total distance walked = [tex]\frac{2}{3}+\frac{3}{5}[/tex]

Total distance walked = [tex]\frac{10+9}{15}[/tex]

Total distance walked = [tex]\frac{19}{15}=1\frac{4}{15}\ km[/tex]

Hence,

Akash walked [tex]1\frac{4}{15}[/tex] kilometers in all.

Answer:

When y=32, x=16.5

Step-by-step explanation:

Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.

We are given:

x varies inversely with y

We can write it as: [tex]x\:\alpha \:\frac{1}{y}[/tex]

[tex]x=\frac{k}{y}[/tex]

We have x = 132, when y=4

We can find value of k by using these values

[tex]x=\frac{k}{y}\\132=\frac{k}{4}\\k=132*4\\k=528[/tex]

We need to find x when y=32

[tex]x=\frac{k}{y}\\x=\frac{528}{32}\\x=16.5[/tex]

So, when y=32, x=16.5

Answer:

Q1) C=2pi r

C= 2 x 7.5 x 3.142

C= 47.13

Q2) A= pi r^2

A= 3.142 x 7.5^2

=3.142 x 56.25

A=176.74

Q3) A= pi r^2

A= pi 6^2

A=36pi mm^2

Q4) A= pi r^2

A= 4^2 x 3.142

A= 50.3

Q5) A=pi r^2

Radius= C/2---------------------> R=14/2--------------> R=7

A=pi x 7^2

A=49 pi cm^2

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{BC}{DC}[/tex] = [tex]\frac{AC}{EC}[/tex] , substitute values

[tex]\frac{3x-5}{32}[/tex] = [tex]\frac{5x-5}{56}[/tex] ( cross- multiply )

56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides

168x - 280 = 160x - 160 ( subtract 160x from both sides )

8x - 280 = - 160 ( add 280 to both sides )

8x = 120 ( divide both sides by 8 )

x = 15

Answer:

y=12x;y=12x−6

Step: Solvey=12xfor y:

y=12x

Step: Substitute12xforyiny=12x−6:

y=12x−6

12x=12x−6

12x+−12x=12x−6+−12x(Add (-1)/2x to both sides)

Answer:

The solution of the system is:

(x, y) = (-1, -6)

Step-by-step explanation:

Given the system of equations

-6x – 3y = 24

4x – 2y = 8

solving the system of equations

[tex]\begin{bmatrix}-6x-3y=24\\ 4x-2y=8\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}-6x-3y=24\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-12x-6y=48[/tex]

[tex]\mathrm{Multiply\:}4x-2y=8\mathrm{\:by\:}3\:\mathrm{:}\:\quad \:12x-6y=24[/tex]

so

[tex]\begin{bmatrix}-12x-6y=48\\ 12x-6y=24\end{bmatrix}[/tex]

adding the equations

[tex]12x-6y=24[/tex]

[tex]+[/tex]

[tex]\underline{-12x-6y=48}[/tex]

[tex]-12y=72[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}-12x-6y=48\\ -12y=72\end{bmatrix}[/tex]

solve -5y=72 for y

[tex]-12y=72[/tex]

Divide both sides by -12

[tex]\frac{-12y}{-12}=\frac{72}{-12}[/tex]

Simplify

[tex]y=-6[/tex]

[tex]\mathrm{For\:}-12x-6y=48\mathrm{\:plug\:in\:}y=-6[/tex]

solving

[tex]-12x-6\left(-6\right)=48[/tex]

[tex]-12x+6\cdot \:6=48[/tex]

[tex]-12x+36=48[/tex]

subtract 36 from both sides

[tex]-12x+36-36=48-36[/tex]

Simplify

[tex]-12x=12[/tex]

Divide both sides by -12

[tex]\frac{-12x}{-12}=\frac{12}{-12}[/tex]

[tex]x=-1[/tex]

Therefore, the solution of the system is:

(x, y) = (-1, -6)

Answer:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

Step-by-step explanation:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

4/9 is basically obtained when we multiply the denominator of 2/3 by 2 and denominator by 3, which is wrong.

Thus, the correction is as follows:

Given the fraction

[tex]\frac{2}{3}[/tex]

Multiply the nominator and denominator of the fraction by 2

[tex]\frac{2\times 2}{3\times 2}=\frac{4}{6}[/tex]

Thus, the 4/6 is the correct equivalent expression of 2/3.

Answer:

Answer:the

Step-by-step explanation:

Answer:

The solution is: (1,-3)

Step-by-step explanation:

Given equations are:

x-y=4     Eqn 1

4x+y = 1     Eqn 2

Substitution involves finding value of a variable from one equation and putting in other equation

From equation 1

x = y + 4

Putting in equation 2

[tex]4(y+4) + y = 1\\4y+16+y = 1\\5y = 1-16\\5y = -15\\\frac{5y}{5} = \frac{-15}{5}\\y = -3[/tex]

Putting y = -3 in equation 1

[tex]x- (-3) = 4\\x + 3 = 4\\x = 4-3\\x = 1[/tex]

Hence,

The solution is: (1,-3)
