Step-by-step explanation:

y= -x +3 and y = x - 1

Answers

Answer:

x=2 and y=1

Step-by-step explanation:

Rewrite equations:

y=−x+3;y=x−1

Step: Solve

y=−x+3

Step: Substitute−x+3foryiny=x−1:

y=x−1

−x+3=x−1

−x+3+−x=x−1+−x(Add -x to both sides)

−2x+3=−1

−2x+3+−3=−1+−3(Add -3 to both sides)

−2x=−4−2x−2=−4−2

(Divide both sides by -2)

x=2

Step: Substitute2forxiny=−x+3:

y=−x+3

y=−2+3

y=1(Simplify both sides of the equation)

Answer:

x = 5.4

Step-by-step explanation:

Corresponding sides are in proportion, that is

[tex]\frac{x}{7.2}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )

4x = 21.6 ( divide both sides by 4 )

x = 5.4

If a triangle has A as 4 and B as 13, but C, the hypotenuse, is missing, what is C? I already got to square root of 185 but i don't understand what to do because you can't simplify it, please show your work/explain it

Answers

Answer:

C = √185 or 13.6 units.

and cannot be simplified any further because it is irrational.

Step-by-step explanation:

Since the triangle has sides A = 4 units and B = 13 units. With C as its hypotenuse side, from Pythagoras' theorem C² = A² + B².

So, substituting A and B into the equation, we have

C² = 4² + 13²

C² = 16 + 169

C² = 185

taking square root of both sides, we have

√C² = √185

C = √185

C cannot be simplified any further because it is irrational. It is best expressed as √185 which is a surd. C could also be expressed as a decimal. So using your calculator and taking √185, C = √185 = 13.605 ≅ 13.6 units.

Which expression is equivalent to 120x2 - 48x?
F 12(10X - 4)
G 12x(10x + 4)
H 12X(-10X - 4)
J 12x(10x - 4)

Answers

The answer is J, because using distributive properties, 12x times 10x would be 120x and 12x times 4 would be 48x!
