if 10 is less than a number is multiplied by 3, the result is equal to 2 times the number. What is the number?

olya-2409 [2.1K]

Hello!

We know that

(x - 10) * 3 = 2x

Distribute the 3

3x - 30 = 2x

Subtract 2x from both sides

x - 30 = 0

Add 30 to both sides

x = 30

The answer is 30

Hope this helps!

For what values of b are the vectors \langle -46, b, 10 \rangle and \langle b, b^2, b \rangle orthogonal

Jet001 [13]

Answer:

b = 6 or b = -6 (non-zero vectors)

b = 0 (zero vector)

Step-by-step explanation:

Two vectors $\vec{a}=\langle a_1,a_2,a_3\rangle$ and $\vec{b}=\langle b_1,b_2,b_3\rangle$ are orthogonal if their dot product is equal to 0, or in other words

$a_1\cdot b_1+a_2\cdot b_2+a_3\cdot b_3=0$

In your case,

$\vec{a}=\langle -46, b, 10\rangle\\ \\\vec{b}=\langle b,b^2,b\rangle$

Hence, if vectors a and b are orthogonal, then

$-46\cdot b+b\cdot b^2+10\cdot b=0\\ \\-46b+b^3+10b=0\\ \\b^3-36b=0\\ \\b(b^2-36)=0\\ \\b(b-6)(b+6)=0\\ \\b=0\text{ or }b=6\text{ or }b=-6$

Note, then if b = 0, then $\vec{b}=\langle 0,0,0\rangle$ and zero-vector is orthogonal to any other vectors.

Thus, b = 6 or b = -6.

write the slope intercept equation. the graph of f passes through (-6,4) and is perpendicular to the line that has an x-intercep

Nimfa-mama [501]

Answer:

y = $-\frac{1}{3} x$ + 2

Step-by-step explanation:

The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:

Slope(s) = Change in y ÷ change in x

s = $\frac{0 - -6}{2 - 0}$ = 3

The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = $-\frac{1}{3}$

Reason: The product of slopes of lines perpendicular to each other have to be -1

So the slope of the perpendicular line that passes through (-6,4) is $-\frac{1}{3}$

As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x

Taking another point (x,y) on the line,

$-\frac{1}{3}$ = $\frac{y - 4}{x - -6}$

$-\frac{1}{3}$ = $\frac{y - 4}{x + 6}$

y - 4 = $-\frac{1}{3}$ x - 2

y = $-\frac{1}{3}$ x + 2

Ms. van Vugt is making brownies. Her recipe calls for 1/2 cup of milk for 12 brownies. She is making 48 brownies. How much milk

Snezhnost [94]

Answer: Ms. Van Vugt will need 2 cups of milk or 1 pint of milk to make 48 brownies.

Step-by-step explanation: For this situation, we know for every 12 brownies she will use 1/2 cup of milk. So we can count up for every 12 brownies.

12 brownies = 1/2 cup of milk

24 brownies = 1 cup of milk

36 brownies = 1 1/2 cup of milk

48 brownies = 2 cups of milk

So, Ms. Van Vugt will need 2 cups of milk or 1 pint of milk to make 48 brownies.
