Hello!
If y varies jointly with x and z, it'll mean that x and z are being multiplied by a factor "k", to equal y.
To give you a visual, this is what I mean.
[tex]y=kxz[/tex]
That means we'll want to find [tex]k[/tex] with the first point we're given: [tex](2,20,5)[/tex]
[tex]20=k(2)(5)[/tex]
[tex]20=10k[/tex]
[tex]k=2[/tex]
Which means our equation is:
[tex]y=2xz[/tex]
Now, let's plug in the [tex]x[/tex] and [tex]z[/tex] from the other point to find [tex]y[/tex].
[tex]y=2(3)(6)[/tex]
[tex]y=36[/tex]
Hope this helps!

Step-by-step explanation:
Jenny is 9 years younger than Sammie. Five years ago, Sammie was four times older
than Jenny. How old is each now?
Answer:
Jenny's age = 8 yr
Sam's age = 17 yr
Step-by-step explanation:
Let x = Jenny's age now
then x + 9 = Sam's age now
x - 5 = Jenny's age 5 years ago
x + 9 - 5 = x + 4 = Sam's age 5 years ago
4(x - 5) = x + 4
4x - 20 = x + 4
3x = 24
x = 8 = Jenny's age now
x + 9 = 8 + 9 = 17 Sam's age now
Check: 5 yrs ago Jenny was 3 and Sam was 12
4(3) = 12, so the answer is correct.

Howard Earned a total of 12$ by selling 8 cups of lemonade. How many ups of lemonade does Howard need to sell in all to earn 21$?
Answer:
Step-by-step explanation:
(12 dollars)/(8 cups) = (12/8 dollars)/cup = (1.5 dollars)/cup
21 dollars × (1 cup)/(1.5 dollars) = 21/1.5 cups = 14 cups
State the ex and Y intercepts for the given function and then graph the function 2X-3Y=6
Answer:
a) (3, 0), (0, -2)
b) see below
Step-by-step explanation:
The x-intercept is found by setting y=0 and solving for x:
2x = 6
x = 6/2 = 3 . . . point (3, 0), x-intercept
The y-intercept is found by setting x=0 and solving for y:
-3y = 6
y = 6/-3 = -2 . . . point (0, -2), y-intercept

Talha had $150. He spent 35% of his money on clothes and 15% on Perfumes. How much money did he spend on the two items?
$60
$75
$50
$85
Answer:
$75
Step-by-step explanation:
150 x 0.35 = 52.50
150 x 0.15 = 22.50
(or do 50% of whole total)
22.50 +52.50 = $75
Answer:
75
Step-by-step explanation:
since he spent a total of 50% of his money (35%+15%), then 50% of 150 is 75
Help anyone please!! Anyone
Answer:
Total surface area = 132 square feet
Step-by-step explanation:
Surface area of the triangular prism = Area of the triangular bases + Area of the lateral rectangular sides
Area of the triangular surface = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}\times 5\times 4[/tex]
= 10 square feet
Area of the rectangular side with dimensions 5ft by 7ft,
Area = 5 × 7 = 35 square feet
Area of the rectangular side with dimensions 7ft by 4ft,
Area = 7 × 4 = 28 square feet
Area of the rectangular side with dimensions 7ft by 7ft,
Area = 7 × 7 = 49 square feet
Total surface area = 2(10) + 35 + 28 + 49
= 132 square feet

n must be 0, since x ⁿ = 1 for all positive, real x if n = 0. So the answer is A.
What is an equation of the line that passes through the points (0,7) and (5,4? Put your answer in fully reduced form.
Answer (assuming it can be in slope-intercept format):
[tex]y = -\frac{3}{5} x+7[/tex]
Step-by-step explanation:
When knowing the y-intercept of a line and its slope, we can write an equation representing it in slope-intercept form, or [tex]y = mx + b[/tex].
1) First, find the slope of the equation. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. Substitute the x and y values of the given points into the formula and simplify:
[tex]m = \frac{(4)-(7)}{(5)-(0)} \\m = \frac{4-7}{5-0} \\m = \frac{-3}{5}[/tex]
Thus, the slope is [tex]-\frac{3}{5}[/tex].
2) Usually, we would have to use one of the given points and the slope to put the equation in point-slope form. However, notice that the point (0,7) has an x-value of 0. All points on the y-axis have an x-value of 0, thus (0,7) must be the y-intercept of the line. Now that we know the slope of the line and its y-intercept, we can already write the equation in slope-intercept format, represented by the equation [tex]y = mx + b[/tex]. Substitute [tex]m[/tex] and [tex]b[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{3}{5}[/tex] in its place in the equation. Since [tex]b[/tex] represents the y-intercept, substitute 7 in its place. This gives the following equation and answer:
[tex]y = -\frac{3}{5} x+7[/tex]
