Me multiply both side by 4 so we can remove the fraction, 12x - 5.6 = 2(3x + 0.7). Distribute 2, 12x - 5.6 = 6x + 1.4. Collect like terms, 6x = 7. Divide both sides by 6 and get x = 7/6!

2. Which is the following equation rewritten in slope-intercept form: -8x = 2 - 2y

Anna007 [38]

Answer:

B, y = 4x + 1

Step-by-step explanation:

to get it into y- intercept form we need to write it in the form y = mx + b

-8x = 2 - 2y, move 2y to the other side and -8x to the other side they both become positive.

2y = 8x + 2, dividing each by 2

yields y = 4x + 1

Hope this helps

At midnight, the temperature was -8oF. At noon, the temperature was 23oF. Which expression represents the increase in temperatur

irinina [24]

Answer:

$23^oF-(-8^oF)$

Step-by-step explanation:

We have been given that at midnight, the temperature was $-8^oF$ . At noon, the temperature was $23^oF$ .

Since our temperature has increased to 23 degree Fahrenheit from -8 degree Fahrenheit, we can represent this increase in temperature as:

$\text{The increase in temperature}=23^oF-(-8^oF)$

Therefore, the expression $23^oF-(-8^oF)$ represents the increase in temperature.

What equation is equivalent to 2^3^x =10

Tresset [83]

Answer:

$log_2(10)$

Simplify the equation using logarithms.

$2^3x=10$

$log_1_0(2^3x)=log_1_0(10)$

log rule ⇩

$log_a(x^y)=y*log_a(x)$

move exponent out of log.

$x*log_1_0(2)=log_1_0(10)$

<em>isolate variable further</em>

$x*log_1_0(2)=log_1_0(10)$

$x=\frac{log_{10}(10)}{log_{10}(2)}$

formula for combining logs. ⇩

$\frac {log_b(x)}{log_b(a)}=log_a(x)$

the result ⇩

$x=log_2(10)$

A flower garden is the shape of a circle. The circumference of the garden is 20 meters. What is the area of the garden. Use 3.14

nadezda [96]

Answer: 255 sq meters

Step-by-step explanation:

C = 2(pi)r

C=Circumference=20 Meters

Pi = 3.14 and r is the radius

So, 20=3.14*r

r=20/3.14=6.36942675

Area = 2(pi)r^2

2*3.14*(6.36942675)^2

254.77707

Round to nearest whole number

A=255 sq meters
