What is the slope of the equation y-3=-4(x-5) ?

Answers

Answer:

m(slope)=-4

Step-by-step explanation:

the slope is the thing you see before x so in this case y-3=-4x+20 so the slope or m is -4.

The slope of the equation y - 3 = -4 ( x - 5 ) is -4.

Given,

y - 3 = -4 ( x - 5 )

We need to find the slope of this equation.

What is the equation of a line with a slope?

The equation is given by:

y - b = m ( x - a)

Where (a, b) is a point that the line passes through and m = slope.

We have,

y - 3 = -4 ( x - 5 )

Here we see that the equation is in the form of y - b = m ( x - a).

Where,

(a, b) = (5, 3)

m = -4

We have,

Slope = m

m = -4

Thus the slope of the equation y - 3 = -4 ( x - 5 ) is -4.

Find the scale factor by 39 / 30

Take that times 10

1.3 x 10 = 13

Since the questions states these two shapes are "similar" the side will have identical scale factors.

Divide the longest side of the bigger shape to the smaller shape.

39 / 30 = 1.3

The scale factor is 1.3.

Now, multiply the shortest side if the smaller shape by the scale factor.

10 * 1.3 = 13

What is the area of triangle QRS?
7 square units
9 square units
10 square units
13 square units

Answers

Circumscribing a rectangle around the triangle SQR, as shown in the figure, we see that the rectangle has dimensions 3 by 6, so its area is 18 square units.


We can also see that the area between the rectangle and the triangle SQR consists of 3 right triangles with dimensions 2 by 3; 6 by 2, and 1 by 4.

The area of there 3 triangles is (2*3)/2 + (6*2)/2 +(1*4)/2 = 3+6+2=11. 


Thus, the area of the triangle is what is left from removing the areas of the 3 surrounding triangles from the area of the rectangle:

A(SQR)=18-11=7 (square units).

Sparkle Cleaners uses 2/3 of a jug of window cleaner in 3 weeks. How much window cleaner do they use in 1 week?

Answers

Answer: 2/9th of a bottle

Step-by-step explanation:

2/3 of a jug = 3 weeks

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

= 2/3 x 1/3 = 2/9

They use 2/9 of a jug of window cleaner in 1 week.

What is a fraction?

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now it is given that,

Cleaner used =  2/3 of a jug

Number of weeks = 3

So, Cleaner used in 1 week = Cleaner used / Number of weeks

Cleaner used in 1 week = (2/3) / 3

Cleaner used in 1 week = 2/9 of a jug

Thus,they use 2/9 of a jug of window cleaner in 1 week.

At the Boxer carnival, you can exchange 40 tickets for various assortments of
prizes. Some of those assortments are below. How many tickets does it take
to get a single tacky mirror?
1 goldfish, 2 tacky mirrors, 1 stuffed tiger
5 goldfish, 1 stuffed tiger
2 goldfish, 3 tacky mirrors

Answers

Answer:

g = number of tickets for goldfish

t = number of tickets for tacky mirrors

s = number of tickets for stuffed tiger

1g + 2t + 1s = 40

5g +     + 1s = 40

2g + 3t         = 40

using the second equatin we can find a value for s

1s = 40 -5g

now substitute in the first equation to get rid of s

1g + 2t + (40-5g) = 40

-4g + 2t         = 0

now use this new equation with equation 3 and solve for one of the values

-4g + 2t = 0

2g + 3t  = 40

multipy the second equation by 2 and then combine

-4g + 2t = 0

 4g + 6t = 80

8t = 80

t = 10  (so it takes 10 tickets to get a takcy mirror)

2g + 3(10) = 40

2g = 10

g = 5  (five tickets to get a goldfish)

s = 40 -5(5)

s = 15  (fifteen tickets for a stuffed tiger)

1(5) + 2(10) + 1(15) (substitute back in the first equation)

5 + 20 + 15

what is the solution for x^2 +14x +15​

Answers

...................................

Step-by-step explanation:

the solution are

x = 1 or x = -15

x^2 + 14x - 15 =0

x^2 + 14x = 15

to write the left hand side as a perfect square we add 49 to both sides :

x^2 + 14x + 49 = 15 + 49

x^2 + 2.x.7 + 7^2 = 64

using the identity (a^2 + b^2) = a^2 + 2ab + b^2

(x + 7)^2 = 64

x + 7 = √64 or x + 7 = -√64

x = 8 - 7 or x = - 8 - 7

Mr. Vectadore is buying two new cowboy hats. All
together the hats cost $75.12. The second hat costs
twice as much as the first hat. What is the price of the
more expensive hat?
Round to the nearest hundredth.

Answers

Answer:

$50.08

Step-by-step explanation:

Let's use x to represent the lesser expensive hat and 2x to represent the more expensive hat since the more expensive hat is twice the price.

So, our equation would be 2x + x = 75.12

We can combine them together to make 3x.

Then, we make the 3x equal to 75.12

3x = 75.12

Now, we solve it.

Divide both sides by 3 to solve for x.

75.12/3 = 25.04

x = 25.04

Lastly, plug it in for 2x to get the price of the more expensive hat.

2(25.04) = ?

2(25.04) = 50.08

Therefore, the price of the more expensive hat is $50.08

A greenhouse contained both 6-inch high geraniums and 3 inch high geraniums. The 6-inch high geraniums were taken out of the greenhouse in early spring and grew at a rate of 1 inch per week. The 3 inch high geraniums remained in the greenhouse and grew at a rate of 1 (1/2) inches per week. After the 6-inch high geraniums were taken outside, in how many weeks were both groups of geraniums the same height.

Answers

Answer:

6 weeks

Step-by-step explanation:

Let the number of weeks be x.

Then we have an equation:

6 + 1*x = 3 + 1 1/2 x6 + x = 3 + 1.5x1.5x - x = 6 - 30.5x = 3x = 3/0.5x = 6 weeks

So after 6 weeks both 6-inch and 3-inch geraniums will have same height
