The equation 4 ( x - 2 ) = 100 is a true equation for a particular value of x. Explain why 2 ( x - 2 ) = 50 is also true for the same value of x.

Answer:

Maybe its c

Step-by-step explanation:

...........

Answer:

x = -2

y = 6

Step-by-step explanation:

i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out

   12x + 15y = 66

+  35x - 15y = -160

   47x = -94

x = -94/47

x = -2

substitute -2 for 'x' to solve for 'y':

4(-2) + 5y = 22

-8 + 5y = 22

5y = 30

y = 6

Answer:

1. Yes

2. 112 ounces

Step-by-step explanation:

To answer this question, we should first convert the amount of pounds Rick's cat weighs into ounces, so that both measurements are in the same unit. Since 1 pound is the same as 16 ounces, we can multiply 7 pounds by 16 ounces:

7 * 16 = 112

So, Rick's cat weighs 112 ounces, which is more than his neighbor's puppy, which only weighs 103 ounces. so for the first question, the answer is:

Yes, Rick's cat weighs more than the puppy.

And the second answer is:

Rick's cat weighs 112 ounces.

Step-by-step explanation:

i did it on edge

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x

Consider the left side

[tex]\frac{cosA}{1-sinA}[/tex] ← multiply numerator/denominator by (1 + sinA)

= [tex]\frac{cosA(1+sinA)}{(1-sinA)(1+sinA)}[/tex] ← expand denominator using FOIL

= [tex]\frac{cosA(1+sinA)}{1-sin^2A}[/tex]

= [tex]\frac{cosA(1+sinA)}{cos^2A}[/tex] ← cancel cosA on numerator/ denominator

= [tex]\frac{1+sinA}{cosA}[/tex]

= right side , thus proven

Answer:

43.5 cm² and 112 cm²

Step-by-step explanation:

Here the instructions aren't given what to do. So I am finding the area of the ∆s .

Area of first ∆ :-

Area of second ∆ :-

Answer:

[tex] \displaystyle 3) \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

[tex] \displaystyle 4)\rm \boxed{112 {cm}^{2} }[/tex]

Step-by-step explanation:

we are given a triangle and we want to figure out the area of it Since we are given the base and the height we can consider the following formula

[tex] \displaystyle \frac{1}{2} bh[/tex]

from the triangle we can assume base and height as 14.5 and 8 respectively Thus substitute:

[tex] \displaystyle \frac{1}{2} (14.5cm)(6cm)[/tex]

reduce fraction:

[tex] \displaystyle (14.5cm)(3cm)[/tex]

simplify multiplication:

[tex] \displaystyle \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

our given shape is trapezoid

therefore recall that,

[tex] \displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h[/tex]

from the shape we define that

now substitute:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \frac{9cm + 19cm}{2} (8cm)[/tex]

reduce fraction:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (9cm + 19cm)(4cm)[/tex]

simplify addition:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (28cm)(4cm)[/tex]

simplify multiplication:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \boxed{112 {cm}^{2} }[/tex]

Answer:

43.75 mph

Step-by-step explanation:

Divide 75 by 4 and divide 4 by 4 which gets the unit rate

The unit rate that represents 175 miles in 4 hours​ is 43.75 miles per hour.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, The distance covered in 4 hours in 175 miles.

We know, Distance = speed×time.

Therefore, 175 = 4×s.

s = 175/4.

s = 43.75 miles per hour.

Step-by-step explanation:

SORRY IF THIS WAS NO HELP

Answer:

D is correct

Step-by-step explanation:

Because the x has the |x| surrounding it, that means that it is always going to be positive (i think) which explains why both -1 and 1 are selected; because they both equal 1.

Step-by-step explanation:

The formula for the slope is y=mx+b, where m is the slope and b is the y-intercept. Since 2 is being multiplied by x, that means it is the slope. The variable y is being added, so it has to be the y-intercept.

Answer:

2=slope & y-intercept=y

Answer:

the slope is -2 and the y-intercept is 3

Step-by-step explanation:

you can rearrange the equation into y=mx+b form which will be y = -2x + 3

the m in y=mx+b is the slope, which in this case is -2.

and the y-intercept is 3 bc is the only constant in the equation.
