Answer:

f(x) = x

Step-by-step explanation:

note : slope is positive 1, so the x term must be positive

also note the graph intersects the curve at y = 0, which means that they y-intercept is zero .

if we substitute this into the general equation for a line

y = mx + b, where m = +1 and b = 0,

we get y = x

or f(x) = x (in function form)

Solve the following<br> 7(-2x+4)=-4x<br> PLS TELL ME QUICKLY

Misha Larkins [42]

Answer:

x = 2.8

Step-by-step explanation:

$7\left(-2x+4\right)=-4x$

$-14x+28=-4x$

$\mathrm{Subtract\:}28\mathrm{\:from\:both\:sides}$

$-14x+28-28=-4x-28$

$\mathrm{Simplify}$

$-14x=-4x-28$

$\mathrm{Add\:}4x\mathrm{\:to\:both\:sides}$

$-14x+4x=-4x-28+4x$

$\mathrm{Simplify}$

$-10x=-28$

$\mathrm{Divide\:both\:sides\:by\:}-10$

$\frac{-10x}{-10}=\frac{-28}{-10}$

$x=\frac{14}{5}$

$x=2.8$

A triangle has an area of 18ft squared. List all the possible positive integers that could represent its base and height. Use se

svet-max [94.6K]

Answer:

1ft x 36ft

2ft x 18ft

3ft x 12ft

4ft x 9ft

6ft x 6ft

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

Area of a triangle = 1/2 x base x height

If area is 18ft², then the dimensions of base x height = 18 x 2 = 36

all the possible positive integers that could represent its base and height can be determined be known by determining the factors of 36

factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, and 36

Possible dimensions of base and heights are :

1ft x 36ft

2ft x 18ft

3ft x 12ft

4ft x 9ft

6ft x 6ft

A circular mirror has a diameter o 12 inches. what is the area , in square inches , of the mirror

Mariulka [41]

The area of ANYTHING circular is (pi) x (the circle's radius)².

Radius = 1/2 of the diameter

Radius of the mirror = 6 inches

Area of the mirror = (pi) x (6 inches)²

= (pi) x (36 inches²) = <em>113 square inches</em> (rounded)

PLEASE HELP ASAP!! I’ll BRAINLEST!!! After surveying students in her homeroom, Katie decided to use a number cube to predict the

mash [69]

Answer:

$\dfrac{1}{216}$

Step-by-step explanation:

In Katie's simulation, a roll of 1 represents staying after school, while rolls of 2, 3, 4, 5, or 6 represent leaving school at the end of classes. Thus,

the probability of staying at school $=\frac{1}{6}$ (only one of six possible outcomes is favorable)

the probability of leaving school $=\frac{5}{6}$ (five of six possible outcomes are favorable)

The probability that three randomly chosen students will all stay after school for extracurricular activities today is

$\dfrac{1}{6}\cdot \dfrac{1}{6}\cdot \dfrac{1}{6}=\dfrac{1}{216}$
