Answer:

[tex]y = \frac{3}{4}x -3[/tex] --- Slope intercept

[tex]4y - 3x =- 12[/tex] --- Standard form

Step-by-step explanation:

Given

The attached linear graph

Required

The equation

Select any two points on the line

[tex](x_1,y_1) = (0,-3)[/tex]

[tex](x_2,y_2) = (4,0)[/tex]

Next, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{0 --3}{4 - 0}[/tex]

[tex]m = \frac{3}{4}[/tex]

The slope intercept is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

So, we have:

[tex]y = \frac{3}{4}(x - 0) -3[/tex]

[tex]y = \frac{3}{4}(x) -3[/tex]

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

Multiply through bu 4

[tex]4y = 3x - 12[/tex]

Subtract 3x from both sides

[tex]4y - 3x =- 12[/tex] --- Standard form

Step-by-step explanation:

m∠A = 70°

m∠B = 30°

m∠C = 80°

Sum of all three angles = 70° + 30° + 80° = 180°

Answer:

27

Step-by-step explanation:

27 plus 29 is 56

Answer:

x = 89°

Explanation:

The angles inside a triangle will always add up to 180°

49 + 42 = 91

180 - 91 = 89°

GE = 26

Step-by-step explanation:

OP = 16 + 9 = 25

PE - OG = 7

Using Pythagorean theorem,

(GE)^2 = (OP)^2 + (PE - OG)^2

=(25)^2 + (7)^2

= 625 + 49

= 674

or

GE = √674 = 25.96 or 26

Answer:

  33

Step-by-step explanation:

The total number of ratio units is 4+7 = 11. If each one stands for an integer number of students, that number is a multiple of 11 between 24 and 40. The only such number is 3×11 = 33.

There are 33 students in the class.

Answer:

{ -6, -4, -2}

Step-by-step explanation:

Since x > - 8, x can be any number greater than - 8.

x = -7, -6, -5, -4,...

BUT, it can't be equal because it's not using this sign [tex]\geq[/tex]

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

1. { -10, -8, -6} can't be an inequality of x because it has -10, -8.

2.{ -8, 0, 8} can't be an inequality of x because of -8.

3.{ -9, 1, 7} can't be an inequality of x because -9 isn't greater than x.

Answer:

Step-by-step explanation:

(27m^8n^4)^(1/3)

= 27^(1/3) (m6)^(1/3)(n)^(1/3) (m^2n)^(1/3)

= 3m^2n(m^2n)^(1/3)

So the answer is the last.

Answer:

7(y + 1/3)

Step-by-step explanation:

7 times the sum of y and 1/3

7    *           (y + 1/3)

7 * (y + 1/3)

7(y + 1/3)

Answer:

100 or 150 units of the product.

Step-by-step explanation:

R = x(1000-4x)

What is the value of x if R = 60,000?

x(1000-4x) = 60000

-4x^2 + 1000x = 60000

x^2 - 250x = -15000

x^2 - 250x + 15000 = 0

Factorize:

(x-100)(x-150) = 0

x-100 = 0 V x-150 = 0

x = 100 V x = 150

Answer:

You would use V=3 times 5 times 4

First you would multipy 5 times 4 then when you get that answer you would multiply the 3.

Answer:

18 jars can be filled completely.

Step-by-step explanation:

7L=7000ml

1 jar contain 375 ml

375ml can be filled in 1 jar

375ml=1 jar

1 ml = 1/375 jar

7000 ml = 7000× 1/375 jar

7000ml= 18.67 jar

hence 18 jars can be filled completely.

The total number of jars that can be filled with sauce is A = 18 jars

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 equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Saj has made 7 litres of curry sauce = 7000 mL

And , each jar can be completely filled with 375 millilitres of cury sauce

So , the number of jars A = 7000 / 375

On simplifying the equation , we get

A = 18.67 jars

Hence , the number of jars is A = 18 jars

Answer:

(-4,10)

Step-by-step explanation:

The coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A is located at (2, 6), and point M is located at (−1, 8). If point M is the midpoint of segment AB.

Then the coordinate of the point B(x₁, y₁) will be

We know that the mid-point formula

[tex]\rm (x, y)= \left ( \dfrac{x_1+x_2}{2}, \ \dfrac{y_1+y_2}{2} \right )\\\\(-1, 8)=\left ( \dfrac{2+x_2}{2}, \ \dfrac{6+y_2}{2} \right )\\\\ \dfrac{2+x_2}{2}=-1 \\\\2+x_2=-1\times 2\\\\x_2=-2-2\\\\x_2=4\\\\\dfrac{6+y_2}{2} =8\\\\6+y_2=8\times 2\\\\6+y_2=16\\\\y_2=16-6\\\\y_2=10[/tex]

Then the coordinate point of B (x₁, y₁) is (−4, 10).

Hence, the coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.

Answer:

$15.75

Step-by-step explanation:

[tex]\frac{y}{15} :\frac{5}{100}[/tex]

y × 100 = 5 × 15

100y = 75

100y ÷ 100 = 75 ÷ 100

y = 0.75

$15 - $0.75

$14.25

[tex]\frac{y}{15} :\frac{10}{100}[/tex]

y × 100 = 10 × 15

100y = 150

100y ÷ 100 = 150 ÷ 100

y = 1.5

$14.25 + $1.50

$15.75
