Answer:

y=9 and x=15

Step-by-step explanation:

ok looking at what they give us in the question we can see that we have two equations. to solve for it be will need to combine them together

note that because they use the word sum we know it's addition

y= x-6

x+y=24

now that we have these we can substitute y=x-6 for the y in our addition equaution such that we have it in terms of one variable:

x+ (x-6) = 24

2x-6=24

2x=30

x=15

now going back we can find Y

15+ y = 24

y=9

Which trig ratio should you use to find the given side?
Zigmanuir [339]

Answer:

D. cosine

Step-by-step explanation:

As it can be seen in the figure, the triangle ABC is a right-angled triangle with Angle C = 90 degree.

In a right angle triangle, there is a formula as following:

<em>cosine (of an acute angle) = length of  adjacent side/ length of hypotenuse</em>

In the figure, the point of angle B and length of hypotenuse AB are given.

We have to calculate x - length of the given side. As BC is the adjacent side of angle B

=> we can use the above formula to calculate x

So that we can use cosine

Find the domain of h(x)= 1/ 3x^2-15x
Schach [20]

Hello!

To find the domain of the function h(x), we need to find the values of x where it is undefined.

We can begin by factoring the denominator of the rational function, h(x).

h(x) = 1/(3x² - 15x) (factor 3x from the binomial)

h(x) = 1/3x(x - 5)

After factoring the denominator, apply the zero product property.

3x = 0 (divide both sides by 3)

x = 0

x - 5 = 0 (add 5 to both sides)

x = 5

The values of 0 and 5 cause h(x) to be undefined. The function h(x) comes from negative infinity to zero, where there is an asymptote. Also, from zero to five, there is also an asymptote. Finally, the function h(x) also goes to infinity from five.  

So therefore, the domain of the function h(x) is: (-∞, 0) ∪ (0, 5) ∪ (5, ∞).

For what value of “a”are the graphs of 5y = -2x + 10 and 3y = aX- 15 parallel
Pie

Answer:

a = -6/5

Step-by-step explanation:

For the graphs to be parallel the graphs should have same slope(m)

So we rewrite both our equations in the slope-intercept form then compare the slope to find the value of a like this,

y=mx+b

This equation is the slope-intercept form we convert both our equations in this form firstly taking equation 1

5y=-2x+10\\\\y=\frac{-2x+10}{5} \\\\y=\frac{-2}{5}x+\frac{10}{5} \\\\y=\frac{-2}{5}x+2

so if we compare it with y = mx + b the coefficient of x is m and hence

m= -2/5 now solving for equation 2

3y=ax-15\\\\y=\frac{ax-15}{3} \\\\y=\frac{ax}{3}-\frac{15}{3}  \\\\y=\frac{a}{3}x-5\\\\

so here if we compare it with y = mx + b the coeffienct of x is a/3 so since parallel lines have same slope by the formula:

m_1=m_2

we equation both the slope to each other to find the value of a like this,

m_1=m_2\\\\\frac{-2}{5}=\frac{a}{3}\\\\-2(3)=a(5)\\\\-6=5a\\-6/5=a

so the value of a equals

a= -6/5

Evaluate the following expression:
Molodets [167]

Answer:

Astronomers were trying to find the weight of six planets - Mars, Venus, Pluto, Jupiter, Mercury, and Saturn. The number of planets lighter than Mars was equal to the number of planets heavier than Venus. Saturn was heavier than Mars and Mercury were heavier than Pluto. Venus was lighter than Mars. Saturn was not the heaviest planet.
