1 fourth B minus 10 equals 7

1 answer:

3 0

$\frac{1}{4}$ b - 10 = 7
Take 10 to the other side.

$\frac{1}{4}$ b = 17

Multiply by 4 to isolate b
$\frac{1}{4}$ b × 4 = 17 × 4

4 and 4 cancels out

b = 68

Identify all factors of the expression 〖4x〗^2+17x-15.

Basile [38]

The factors of given expression are: -5 and 3/4

Step-by-step explanation:

Given equation is:

$4x^2+17x-15$

Making pairs for the mid-term 17x by factoring the product of co-efficient of 4x^2 and 15

$4x^2+20x-3x-15$

$= 4x(x+5) - 3(x+5)$

$=(4x-3)(x+5)$

Now

$4x-3 = 0\\4x = 3\\x = \frac{3}{4}$

$x+5 = 0\\x = -5$

Hence,

The factors of given expression are: -5 and 3/4

Which of the following is the equation of a line in slope-intercept form for a

Triss [41]

Answer:

Step-by-step explanation:

Slope m = 2

The point is (0,3)

x1 = 0 and y1 = 3

And y - y1 = m(x - x1)

y - 3 = 2(x - 0)

y - 3 = 2x

y = 2x + 3 this is the equation
