Descibe the mothod of solving problems with numbers in standard form ?? I have 5 MIN

1 answer:

6 0

Answer: A standard equation is set up like this: Ax + By = C (where A, B, and C represent numbers). To find the slope (or the rate at which something changes) you must divide the value of A by the value of B (A / B).

i need help Samir needs 450g of butter to make 60 shortbread biscuits.How many will he use to make 12 biscuits?

Gnom [1K]

<h3>Answer: 90 g of butter </h3>

================================================

Work Shown:

450 g of butter = 60 biscuits

450/60 g of butter = 60/60 biscuits ... divide both sides by 60

7.5 g of butter = 1 biscuit

This means each biscuit needs 7.5 grams of butter

Multiply both sides by 12 to get

7.5 g of butter = 1 biscuit

12*7.5 g of butter = 12*1 biscuit

90 g of butter = 12 biscuits

Explain why S = {(5, 4, -2), (-15, -12, 6), (10, 8, -4)} is NOT a basis for R^3 (1 point Sis linearly dependent and spans R3 S i

earnstyle [38]

$S$ would be a basis for $\mathbb R^3$ if

(1) the vectors in $S$ are independent, and

(2) the vectors span $\mathbb R^3$ .

Linear independence requires that $c_1=c_2=c_3=0$ is the only solution to

$c_1(5,4,-2)+c_2(-15,-12,6)+c_3(10,8,-4)=(0,0,0)$

These vectors are not linearly independent because if $c_1=3$ , $c_2=1$ , and $c_3=0$ , we have

$3(5,4,-2)+(-15,-12,6)=(15-15,12-12,-6+6)=(0,0,0)$

so $S$ is not a basis for $\mathbb R^3$ .

What is the y-intercept of the line passing though the point (9,-7) with a slope of -1/8

Tomtit [17]

Answer:

y-intercept (0, -47/8)

Step-by-step explanation:

Point slope equation form:

y + 7 = -1/8(x - 9)

y + 7 = -1/8 x + 9/8

y = -1/8 x + 9/8 - 56/8

y = -1/8 x - 47/8

y = mx + b where m=slope and b = y intercept

In this case, y intercept = -47/8

Answer:

y-intercept (0, -47/8)
