Answer:

h(x) = 31

Step-by-step explanation:

When it says find h (2), you will have to replace x with 2

h(x) = 3x^2 -5

h(x) = 3(2)^2 -5

h(x) = 6^2 - 5

h(x) = 36 - 5

h(x) = 31

Hope this helps =)

11/12 divide by 2 5/8

lutik1710 [3]

Answer:

22/63

Step-by-step explanation:

Keep, change, and flip is how you divide fractions. You change divide to multiply and then turn 2 5/8 into an improper fraction. And you will get 21/8. Next, flip that number to the reciprocal, which is 8/21. Multiply 8/21 with 11/12 to get 22/63.

What is the equation of a line that passes through the point (8, −2) and is parallel to the line whose equation is 3x + 4y = 15?

Dafna1 [17]

Step 1

Find the slope of the given line

we have

$3x+4y=15$

Isolate the variable y

Subtract $3x$ both sides

$3x+4y-3x=15-3x$

$4y=-3x+15$

Divide by $4$ both sides

$y=-\frac{3}{4}x+ \frac{15}{4}$

the slope of the given line is

$m=-\frac{3}{4}$

Step 2

Find the equation of the line that passes through the point $(8,-2)$ and is parallel to the given line

we know that

if two lines are parallel, then their slopes are equal

The equation of the line into point-slope form is equal to

$y-y1=m(x-x1)$

we have

$m=-\frac{3}{4}$

$(x1,y1)=(8,-2)$

substitute in the equation

$y+2=-\frac{3}{4}(x-8)$

$y=-\frac{3}{4}x+6-2$

$y=-\frac{3}{4}x+4$ or $3x+4y=16$

therefore

the answer is

$y=-\frac{3}{4}x+4$

$3x+4y=16$

Jonathan and Byron both have comic book collection the number of books in the collection form a ratio 4:9 of Jonathan's to Byron

worty [1.4K]

Since the ratio is 4:9 your trying to find the sum. What I mean is that if it's 4 to 9, whats 20+9? =29. Do the same for 4. 20+4= 24. Now you find the difference in order to find how much does Byron have compared to Jonathan. So 29-24= 5
