Answer:

Elimination

Step-by-step explanation:

You would not do substitution since it would not work so you do elimination since the 4y and -4y eliminate then you just solve for it.

How do you solve 32 - 6x = 53?

katrin2010 [14]

$\large\boxed{x=-\frac{7}{2}}$

To solve for $x$ , we need to isolate it on one side of the equation.

The most important part of this is knowing that whatever we do to one side of the equation, we must also do to the other.

Subtract 32 from both sides of the equation.

$\begin{aligned}32-32-6x&=53-32\\-6x&=21\end{aligned}$

Divide both sides of the equation by $-6$ .

$\begin{aligned}\frac{-6x}{-6}&=\frac{21}{-6}\\x&=\boxed{-\frac{7}{2}}\end{aligned}$

What is the slope of the line for BOTH graphs? Are the slopes the same or different?

Y_Kistochka [10]

Answer:

both are -10

Step-by-step explanation:

x1 y1 x2 y2

1.5 180 6 135

(Y2-Y1) (135)-(180)= -45 ΔY -45

(X2-X1) (6)-(1.5)= 4.5 ΔX 4.5

slope= -10

B= 195

Y =-10X +195

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

x1 y1 x2 y2

1 175 8 105

(Y2-Y1) (105)-(175)= -70 ΔY -70

(X2-X1) (8)-(1)= 7 ΔX 7

slope= -10

B= 185

Y =-10X +185

Y= 2.5x+ 5.8 when x = 0.6 pls find the function

adoni [48]

You’d plug in the 0.6 for x. so you’d multiple 0.6 times 2.5 then you’d get 1.5 then you’d add 1.5 plus 5.8 and get 7.3

30 POINTS I WILL GIVE U BRAINLIEST AND THANKS AND 5 STARS please help this is very important this is a big part of my grade

mars1129 [50]

Answer:

$1.\:2^x=64, x=\boxed{6},\\2.\:x=\left(\frac{2}{3}\right)^3,x=\boxed{\frac{8}{125}}\\3.\:3\cdot (3^4)=3^x, x=\boxed{5}\\4.\:\frac{16}{25}=x^2,x=\boxed{\frac{4}{5}},$

Step-by-step explanation:

$1.\\\\2^x=64,\\\log 2^x=\log64,\\x\log 2=\log 64,\\x=\frac{\log 64}{\log 2}=\boxed{6}$

$2.\\x=\left(\frac{2}{5}\right)^3=\frac{2^3}{5^3}=\boxed{\frac{8}{125}}$

3. This problem incorporates an exponent property.

Exponent property used: $a^b\cdot a^c=a^{(b+c)}$ , yielding an answer of $\boxed{5}$

$4.\\\\\frac{16}{25}=x^2,\\x=\sqrt{\frac{16}{25}}=\frac{\sqrt{16}}{\sqrt{25}}=\boxed{\frac{4}{5}}$
