What is the answer for. -3x > -15
lana [24]

Answer:

x<5

Step-by-step explanation:

-3x > -15

Divide -3 on both sides:

\frac{-3x}{-3} >\frac{-15}{-3}

x<5

*Note the sign switches because

the x is negative. The sign only

switches when the number you

are dividing by is negative.*

Urgent ASAP!! Imagine math
Paraphin [41]

Answer:

Graph A = 20miles/gallon

Graph B = 20

Step-by-step explanation:

For graph A, to find the change you will need to choose two points from the graph (the easier the better)

So for example, I've chosen 40miles-2gallons (2, 40) and point 0 (0, 0)

Now you will need to remember the slope formula which is:

m=\frac{y_2-y_1}{x_1-x_2}

so your point (x1, y1) will be (0, 0)

and point (x2, y2) will be (2, 40)

so m=\frac{40-0}{2-0}

which is m=\frac {40}{2} = 20

and so you get that the slope will be 20 miles/gallon

For graph B, what they want you to see is that change of y/change of x means the same as change of miles/change of gallons since x is the gallons and y is the miles.

What is the meaning of the slope of the line ?
Mila [183]

Step-by-step explanation: In algebra, we use the word <em>slope</em> to describe how steep a line is and slope can be found using the ratio <em>rise/run </em>between any two points that are on that line.

The ratio <em>rise/run</em> is the equal to the rate of change

or the <em>change in y/change in x</em>.

In algebra, the rate of change or the <em>change in y/change in x</em> or

the <em>rise/run</em> is also called the slope of a line.

Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square units. a. How many times larger is the are
PSYCHO15rus [73]

Answer:

The answer is below

Step-by-step explanation:

a) Triangle A is attached in the image below.

The base of triangle A is 3 units and its height is 3 units. The area of a triangle  is given as:

Area = (1/2) × base × height

Area of triangle A = (1/2) × base × height = (1/2) × 3 × 3 = 4.5 unit²

Area of the scaled copy = 72 unit²

Ratio of area = Area of the scaled copy / Area of triangle A = 72 unit² / 4.5 unit² = 16

Hence the scaled copy area is 16 times larger than that of triangle A.

b) For the scaled copy:

Area of the scaled copy = (1/2) × base × height = 72 unit²

base × height = 144

Since the base and height are equal

base² = 144

base = 12, also height = 12

Base of scaled copy = 12 = 4 × base of triangle A

Therefore the scale factor used is 4
