Answer:

a: $-20+12y$

Step-by-step explanation:

$10-6\left(5-2y\right)$

Expand:

$10-6* \:5-\left(-6\right)* \:2y$

$10-6* \:5+6* \:2y$

$10-30+12y$

Subtract:

$-20+12y$

Your question has been heard loud and clear.

10-6(5-2y) = 10 - 30 +12y = -20+12y.

(All you have to do is multiply -6 with 5 and -2y , then simplify the equation)

Thank you

Write various of the equation of a line that passes through (-6, 3) and has a slope of - 1/3

pishuonlain [190]

Answer:

$\large\boxed{y-3=-\dfrac{1}{3}(x+6)-\text{point-slope form}}\\\boxed{y=-\dfrac{1}{3}x+1-\text{slope-intercept form}}\\\boxed{x+3y=3-\text{standard form}}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We have

$m=-\dfrac{1}{3},\ (-6,\ 3)\to x_1=-6,\ y_1=3$

Substitute:

$y-3=-\dfrac{1}{3}(x-(-6))\\\\y-3=-\dfrac{1}{3}(x+6)$

Convert to the slope-intercept form

$y=mx+b$

$y-3=-\dfrac{1}{3}(x+6)$ <em>use the distributive property</em>

$y-3=-\dfrac{1}{3}x-2$ <em>add 3 to both sides</em>

$y=-\dfrac{1}{3}x+1$

Convert to the standard form

$Ax+By=C$

$y=-\dfrac{1}{3}x+1$ <em>multiply both sides by 3</em>

$3y=-x+3$ <em>add x to both sides</em>

$x+3y=3$

5x-3 =2x+15 <br> Someone pls help for geometry

inysia [295]

Answer:

x = 6

Step-by-step explanation:

5x-3 = 2x+15

<h3>i) move 2x to the left-hand side and change its sign</h3>

5x-2x-3 = 15

<h3>ii) move -3 to the right-hand side and change its sign</h3>

5x-2x = 15+3

<h3>iii) collect like terms</h3>

3x = 15+3

<h3>iv) add the numbers</h3>

3x = 18

<h3>v) divide both sides of the equation by 3</h3>

$\frac{3x}{3} = \frac{18}{ 3}$

$x = 6$

13. The equation of line l is given as y = 0.6x – 4.

Luden [163]

Answer: 16.6

Step-by-step explanation:

a = slope = 0.6

b = y-intercept = -4

c = x intercept = 20/3. (Set y=0 and solve for x)

So, a+b+3c = 0.6 - 4 + 3*20/3 = 16.6

A basketball player makes 60% of his free throws. We set him on the line of free-throw and informed him to shoot free throws unt

pshichka [43]

Answer:

B. 0.03110

Step-by-step explanation:

Given

Probability of Hit = 60%

Required

Determine the probability that he misses at 6th throw

Represent Probability of Hit with P

$P = 60\%$

Convert to decimal

$P = 0,6$

Next; Determine the Probability of Miss (q)

Opposite probabilities add up to 1;

So,

$p + q = 1$

$q = 1 - p$

Substitute 0.6 for p

$q = 1 - 0.6$

$q = 0.4$

Next,is to determine the required probability;

Since, he's expected to miss the 6th throw, the probability is:

$Probability = p^5 * q$

$Probability = 0.6^5 * 0.4$

$Probability = 0.031104$

Hence;

<em>Option B answers the question</em>
