Answer:

Step-by-step explanation:

When an expression is evaluated, the expression is either simplified or calculated.

The result of the expression is 47

The expression is given as:

Where:

x = 2 and y = 4

Substitute 2 for x and 4 for y in the expression

So, we have:

Evaluate all exponents

Evaluate all products

Evaluate like terms

Hence, the result of the expression is 47

Are all equilateral triangles similar? Justify your answer.

Juli2301 [7.4K]

Yes all equilateral triangles are congruent. You can prove congruence with two congruent angles and all equilateral triangles will have 60º angles. Which is enough to prove similarity

nordsb [41]

Answer:

A. $6000

Step-by-step explanation:

Let the invested amount is x.

<u>Then the interest amount is:</u>

x*5*2.25/100 = 675
0.1125x = 675
x = 675 / 0.1125
x = 6000

Correct choice is A

write an equation of the perpendicular bisector of the line segment whose endpoints are (-1,1) and (7,-5)

gladu [14]

Find midpoint of segment.
(-1,1), (7,-5)
$x= \frac{-1+7}{2}=3,y= \frac{1+(-5)}{2}=-2$

Find slope of line which passes through (-1,1) and (7,-5).
$m= \frac{-5-1}{7-(-1)}= \frac{-6}{8}=- \frac{3}{4}$

The slope of perpendicular line is negative reciprocal value of m.
$m_{\perp}=- \frac{1}{m} =- \frac{1}{- \frac{3}{4} } = \frac{4}{3}$

Write quation of line which slope is $\frac{4}{3}$ and passes throug the point (3,-2).
$m=\frac{4}{3},x_1=3,y_1=-2
\\y-y_1=m(x-x_1)
\\
\\y-(-2)=\frac{4}{3}(x-3)
\\
\\y+2=\frac{4}{3}x-\frac{8}{3}
\\
\\3y+6=4x-8
\\4x-3y-14=0$

At what point does the line given by the following equation cross the y-axis? y = (6/9)X + 9

Elodia [21]

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{6}{9}$ x + 9 ← is in slope- intercept form

with y- intercept c = 9

then the line crosses the y- axis at (0, 9 )

After a 40% discount an item costs $360. what is the original cost

Reptile [31]

Original Price = Final Price / (100 - Discount)

So...

OP = 360 / 100 - 0.40
OP = 360 / 0.60
OP = 600

The original price is $600.

To check, do 600 - (600 * 0.40) in a calculator. You get 600 - 240 = 360, the discounted cost.
