Answer:

  y = 3x +6

Step-by-step explanation:

Put the numbers in the formula in their corresponding places.

  y = mx + b . . . . slope-intercept form with slope m, intercept b

  y = 3x +6 . . . . . slope-intercept form with slope 3, intercept 6

Answer:

The top of the ladder is 6.3 feet high from the ground.

Step-by-step explanation:

The given question can be expressed by the three sides of a right angled triangle. Let the height of the top of the ladder from the ground be represented by h.

Thus, applying the Pythagoras theorem to determine h, we have;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]11^{2}[/tex] = [tex]h^{2}[/tex] + [tex]9^{2}[/tex]

121 =  [tex]h^{2}[/tex] + 81

[tex]h^{2}[/tex] = 121 - 81

    = 40

h = [tex]\sqrt{40}[/tex]

  = 6.325

h = 6.325 feet

The top of the ladder is 6.3 feet high from the ground.

Answer:

Tanisha's car uses 7 gallons of gas driving 175 miles.

Step-by-step explanation:

With the information provided, you know that Tanisha can drive about 300 miles between 12-gallon fill-ups and with this you can find the gallons of gas needed to drive 175 miles by writing a proportion using this form:  a/b = c/d.

12/300=x/175

This indicates that 12 is to 300 as x is to 175. We write x because we don't know the gallons needed yet. Now, we have to cross products and solve for x to find the answer:

12*175=300x

2100=300x

x=2100/300

x=7

According to this, the answer is that Tanisha's car uses 7 gallons of gas driving 175 miles.

Answer:

m [ slope ] = 8/3

Step-by-step explanation:

What is the slope of the line that passes through the points (5, 1) and (2, -7)?

m = ∆y / ∆x

m = y₂ – y₁ / x₂ – x₁

| (5, 1) → (x₁, y₁) | (2, -7) → (x₂, y₂) |

[each coordinate will correspond (directly go to) to the variables shown]

m = (-7) – (1) / (2) – (5)

m = -8 / -3

m = 8 / 3

This means that this line has a rise of 8 and a run of 3.

Up 8 and right 3 proportionally, it would touch the opposite corners of a plane that was 8 by 3 units.

Slope can be thought of as the steepness of a line, the greater the slope, the greater the steepness.

These points are generally known as cartesian coordinates.

____________

Once you have the slope, you can back track from one of the coordinates to find the equation of the line.

Just multiply the slope by the x of either coordinate, make it opposite, and then add that to the y of that coordinate to get b [the y-intercept; where it crosses the y axis, x is always 0]

Since (2, -7) is closer to the y axis than (5, 1) it is more convenient.

In (2, -7), 2 is the x variable and -7 is the y variable.

-mx + y = (-8/3)(2) + (-7) = -16/3 + (-21/3)

21/3 is the same as 7 [so it will have a common denominator].

-16 + -21 / 3 = -37/3 = b

Thus this line has an equation of

y = mx + b

↓ ↓

y = 8/3x – 37/3.

__________________________

Or you can refer to point slope which is what is taught:

y – y₁ = m(x – x₁).

You can tell that there are some similarities to this and the slope formula.

m = ( y₂ – y₁ / x₂ – x₁ ) →

m × ( x₂ – x₁ ) =

( y₂ – y₁ / x₂ – x₁ ) × ( x₂ – x₁ )

[multiply the denominator by both sides]

m ( x₂ – x₁ ) = y₂ – y₁

[x₂, and y₂ can just be x and y since you only need the initial coordinate and slope, because the second coordinate can be anything along that line]

m ( x – x₁ ) = y – y₁ →

y – y₁ = m(x – x₁)

[symmetric property of equality]

if a = b, b = a.

18. What is the y-intercept of the line BC?

b) -3

Answer:

C

Step-by-step explanation:

It intercepts the horizontal line between -2 and -3, so that means that it is not a whole number. Therefore, the only answer possible is -2.3.

Answer:

Option C. Side a 1.5 inches long, side b is 2 inches long and side c is 2.5 inches long

Step-by-step explanation:

The scale factor=4:1=4/1

Scale factor=(Scale drawing)/object

4/1=6/a

4a=6

a=6/4

A=1.5 inches

4/1=8/b

4b=8

b=8/4

B= 2 inches

4/1=10/c

4c=10

c=10/4

C=2.5 inches

Therefore, side a is 1.5 inches long and side b is 2 inchea long and side c is 2.5 inches long

Answer:

C

Step-by-step explanation:

with the scale factor being 4:1 (meaning shape A is bigger then shape B by 4 times) we can divide the larger shapes dimensions by 4 to get ur answer

The distributive property.

Step-by-step explanation:

The distributive property is when you distribute a number to different numbers in a parentheses. For example...

2*x would be 2x, and 2*4 would be 8.

Answer:

The answer is 64

Step-by-step explanation:

Answer:

64

Step-by-step explanation:

12 + (8 x (4 + 3) + 2) - 6

= 12 + ( 8 x 7 + 2 ) - 6

= 12 + ( 56 + 2 ) - 6

= 12 + 58 - 6

= 70 - 6

= 64

This is a function as there is only one unique value of y for any unique value of x. It passes the ‘vertical line test’.

So insert ‘F’ as this is a function.

Answer:

F

Step-by-step explanation:

this is a function because it is just a reflection over the x-axis

the function is f(x) = -(x - 1)^2 + 3
