Four less than 5 times a number is the same as 26 more than twice the number.

Tju [1.3M]

Answer:

False

Step-by-step explanation:

5x - 4 versus 2x + 26

Imagine x equals 1, then the equations would be:

5(1) - 4 and 2(1) + 26

1 and 28 are not equivalent.

Another example would be x = 6

5(6) - 4 and 2(6) + 26

26 and 38 are not equivalent.

No matter what you replace x with, the expressions are never equal.

Which of the following expressions could be used to find the area of the larger rectangle? 3(64 mm2) 9(64 mm2) 9(32 mm2) 3(576 m

kari74 [83]

Answer:

$9(64)\ mm^{2}$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=bh$

In this problem we have

the larger rectangle

$b=48\ mm$

$h=12\ mm$

substitute

$A=48*12=(4*4*3)(4*3)=(3*3)(4*4*4)=9(64)=576\ mm^{2}$

In the xy-plane, the graph of x2 − 4x + y2 − 6y = −8 is a circle. What is the radius of the circle?

Blizzard [7]

The center-radius form of the circle equation

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have:

$x^2-4x+y^2-6y=-8$

Use

$(a-b)^2=a^2-2ab+b^2\qquad(*)$

$x^2-2(x)(2)+y^2-2(y)(3)=-8\qquad\text{add}\ 2^2\ \text{and}\ 3^2\ \text{to both sides}\\\\\underbrace{x^2-2(x)(2)+2^2}_{(*)}+\underbrace{y^2-2(y)(3)+3^2}_{(*)}=2^2+3^2-8\\\\(x-2)^2+(y-3)^2=4+9-8\\\\(x-2)^2+(y-3)^2=5\\\\(x-2)^2+(y-3)^2=(\sqrt5)^2\\\\Answer:\\\\\boxed{center:(2,\ 3)}\\\\\boxed{radius:r=\sqrt5}$
