Answer:

Step-by-step explanation:

because 9 is in front of the variable y

whenever there is a number before a variable then that number is a coefficient

For example:

3x+2x+5x=y

3,2,5 are all coefficients of x

A baker is making bread dough. He uses 3 cups of flour for every 8 ounces of water. How many cups of flour will he use if he use

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

This is the fraction we use to solve this problem $\frac{Ounces}{Flour}$

Fractions are $\frac{8}{3}$ and $\frac{96}{x}$

We now ask ourselves

$8 * x = 96\\x = 12$

Since whatever we do to the numerator we have to to the same to the denominator, we multiply 3 and 12

$3 * 12 = x\\x = 36$

Hope this helps!

Work out an equation of the straight line with gradient 3 that passes through the point with coordinates (2, 4).

Gnom [1K]

Answer:

The answer is

$\huge \boxed{y = 3x - 10}$

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

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

where

m is the slope

( x1 , y1) is the point

From the question the point is (2, 4) and the slope is 3

The equation of the line is

$y - 4 = 3(x - 2) \\ y + 4 = 3x - 6 \\ y = 3x - 6 - 4$

We have the final answer as

$y = 3x - 10$

Hope this helps you

Now Cathy is three times as old as Katie. In six years Cathy will be only twice as old as Katie. How old is each girl now?

BabaBlast [244]

Katie is 6; Cathy is 18!

X- Katie’s age now and 3x -Cathys age now
In 6 years, Katie is 12 and Cathy is 24.

2 x (X+6) = 3x + 6
2x + 12 = 3x + 6
6 = x

When you multiply exponents with the same base, you add the exponents.
3+-5+y=-2
-2+y=-2
y=0

Final answer: y=0
