-1/5 plus 7/10 <br><br> Whats the answer ??/
lubasha [3.4K]

Answer:

Hi Friend!

The Correct Answer is 1/2

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(-1/5, 7/10) = 10

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

2) Multiply<br> (6x+3)(3x2+8x+5)<br> Help, please shore me how to do this!
Brrunno [24]

Answer:

Result :

3 • (2x + 1) • (x + 1) • (3x + 5)

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2".

STEP1

Equation at the end of step 1

(6x + 3) • ((3x2 + 8x) + 5)

STEP2

STEP3

Pulling out like terms

3.1 Pull out like factors :

6x + 3 = 3 • (2x + 1)

Trying to factor by splitting the middle term

3.2 Factoring 3x2 + 8x + 5

The first term is, 3x2 its coefficient is 3 .

The middle term is, +8x its coefficient is 8 .

The last term, "the constant", is +5

Step-1 : Multiply the coefficient of the first term by the constant 3 • 5 = 15

Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .

-15 + -1 = -16

-5 + -3 = -8

-3 + -5 = -8

-1 + -15 = -16

1 + 15 = 16

3 + 5 = 8 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5

3x2 + 3x + 5x + 5

Step-4 : Add up the first 2 terms, pulling out like factors :

3x • (x+1)

Add up the last 2 terms, pulling out common factors :

5 • (x+1)

Step-5 : Add up the four terms of step 4 :

(3x+5) • (x+1)

Which is the desired factorization

sorry if its too much...

6. Write the equation of the line in slope-intercept form given the following:
Juliette [100K]

Answer:

y=\dfrac{5}{4}x+1

Step-by-step explanation:

Slope intercept form a equation of a line is given by the following formula:

Slope intercept form:

y=mx+c

Given that, a point is (-4,-4)

i.e.

x=-4,\\y=-4

Slope, m =\frac{5}{4}

Putting the given values in the Slope intercept form equation:

-4=-4\times \dfrac{5}{4}+c\\\Rightarrow -4=-5+c\\\Rightarrow c =1

Putting the value of c and m in the slope intercept form:

y=\dfrac{5}{4}x+1

What is the value of the expression below when y=6y=6? y^2 -5y-4 y 2 −5y−4
Elodia [21]

Answer:

2

Step-by-step explanation:

Given expression:

y^2 - 5y - 4

y = 6

Substitute y = 6 into the expression

y^2 - 5y - 4

6^2 - 5(6) - 4

(6*6) - (5*6) - 4

36 - 30 - 4

36 - 34

2

The value of the expression y^2 - 5y - 4 is 2 when y = 6
