Point slope form is: y - y1 = m(x - x1)

So we plug in the point we were given, and use the slope, m:

y -5 = 4(x - 2) ANSWER

Now: y - 5 = 4x - 8,

so: y = 4x - 8 +5

so: y = 4x - 3 ANSWER

(SLOPE INTERCEPT FORM IS: y =mx + b)

Someone please help me

Answer:

The answer is x = 4

Step-by-step explanation:

1. First you need to distribute the 3/4 * (x + 8). This looks like (3/4) * (x) + (3/4) * (8) = 9

2. Next you simplify the distributed equation, 3/4x + 6 = 9

3. Now subtract 6 from both sides, 3/4x = 3

4. Multiply both sides by 4/3, 4/x * 3/4x = 3 * 4/3

5. Simplify, x = 4

Njh by how many is 3 fours of 20 greater than 3 fiths of 20?

VMariaS [17]

To calculate a fraction of a quantity, multiply the quantity by the numerator of the fraction and divide by the denominator

$\frac{3}{4}$ of 20 = (3 × 20 )/4 = $\frac{60}{4}$ = 15

$\frac{3}{5}$ of 20 = (3 × 20 )/5 = $\frac{60}{5}$ = 12
