Answer:

The slope of the line is negative. The y-intercept is 5. The slope of the line is -2/3.

Step-by-step explanation:

With 2 given points on the line that are whole numbers, you can find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex]. The answer will tell you whether it's negative or positive. For example, [tex]m=\frac{-2-1}{4-0} =\frac{-3}{4}[/tex]. The slope is negative for the example. The y-intercept would be the point with 0 as the x-value: (0, -5).

Answer:

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.

The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:

a + b > c;   a + c > b;   b + c > a

Given a triangle with side length 4 m, 8 m, 9 m:

4m + 8m = 12m > 9m

4m + 9m = 13m > 8m

8m + 9m = 17m > 4m

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

Answer:

y = -2x + 7

Step-by-step explanation:

Answer:

Step-by-step explanation:

recall   the two formulas

y = mx - b            slope-intercept

y - y1 = m(x-x1)     point-slope

with these  we can get the equation .  we also need to find the slope  m

m =  y2-y1 / x2-x1

m = 3 - (-1) / 2-4

m = 3 + 1 / -2

m = 4 / -2

m = -2

now with the slope known,  plug in either point into the point-slope formula and work to the slope-intercept formula, I'll use (2,3)  as the point to plug in.

y - 3 = -2(x-2)

y - 3 = -2x +4

y = -2x + 7

there.. that's your answer

y = -2x + 7

Answer:

$3.50

Step-by-step explanation:

1) 4 friends each bought a movie ticket = 7.50 * 4 = 30

2) subtract from total cost = 58 - 30 = 28

4) total number of candy boxes is 8 (because each friend bought 2 boxes so 4*2 is 8)  = 28/8 = 3.5

5) money so = $3 dollars and 50 cents

Hey There!

When it ask for the scale factor its asking for what did you have to multiply the side length by of figure a to get the similar side length of figure b

for example in figure A the base length is 7

to get the the base length of figure B (14) they multiplied the base length of figure A by 2

7x2=14

therefore the scale factor is 2

Answer:

  31.243 units

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. Using the attached figure, it is convenient to find the length of BE as an intermediate step in the solution.

  Sin = Opposite/Hypotenuse

  sin(30°) = BE/100

  BE = 100·sin(30°)

Then ...

  Tan = Opposite/Adjacent

  tan(58°) = BE/x

  x = BE/tan(58°) = 100·sin(30°)/tan(58°)

  x ≈ 31.243 . . . . units

_____

Comment on the figure

The intermediate problem in creating the figure was to locate point D. That was accomplished by locating point C on a line at an angle of 58° CCW from the horizontal, using point B as a center. Then D is the intersection of BC with the x-axis. BE is drawn perpendicular to the x-axis.

Answer:

127.41ft^2

Step-by-step explanation:

Given data

DImension of the square

10ft by 10ft

The perimeter of the square is

=10+10+10+10

=40ft

Hence the amount of the fencing of the circle is 40ft

That is the circumference is 40ft

C=2πr

solve for r

40=2*3.14*r

40=6.28r

r= 40/6.28

r=6.37 ft

Area= πr^2

Area= 3.14*6.37^2

Area= 3.14*40.5769

Area= 127.41ft^2

Answer:

x=2

Step-by-step explanation:

Distribute the 7 across the 2x and 3:

[tex](7)(2x)-3(7)=7[/tex]

[tex]14x-21=7[/tex]

Isolate the x term by adding 21 on both sides:

[tex]14x=28[/tex]

Isolate x by dividing by 14 on both sides:

[tex]\frac{14x}{14}=\frac{28}{14}[/tex]

[tex]x=2[/tex]

Answer:

n=1.5

Step-by-step explanation:

distribute: 1.2n-5.4= 3.4-2(3n-1)

Add numbers]: 1.2 n - 5.4= 5.4-6n

Move terms: 1.2n+6n- 5.4=5.4

Add like terms: 7.2n= 5.4+5.4

Divide both sides of equation by 7.2

Lindsey would need to use 4/3 cups of sugar to make a full batch of cookies.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can use proportions to solve this problem.

If 2/3 cups of sugar are used to make 1/2 batch of cookies, then we can set up the following ratio:

2/3 cups of sugar : 1/2 batch of cookies

We want to find how much sugar is needed for a full batch of cookies. Let's call this amount x cups of sugar.

We can set up another ratio:

x cups of sugar : 1 full batch of cookies

To solve for x.

(2/3 cups of sugar) x (1 full batch of cookies) = (1/2 batch of cookies) x (x cups of sugar)

2/3 = 1/2 (x)

x = (2/3) / (1/2)

x = 4/3

Therefore,

Lindsey would need to use 4/3 cups of sugar to make a full batch of cookies.
