How to Factor r^2-5r-14
12345 [234]

Answer:

(r-7)(r+2)

Step-by-step explanation:

First, let's look at the -14. Possible factors for that number are (-2, 7) (2, -7) (1, -14) and (-1, 14).

Now, let's look at the -5. How can we make -5 with the pairs that we just found?

The only possible way is 2 and -7 (added together equals -5)

PLEASE HELP QUICKLY!!!! What is the equation of the line with a slope of -3/4 that goes through the point (−6, 3)?
Yakvenalex [24]

Answer:

y=-\frac{3}{4}x-\frac{3}{2}

or

y=-0.75x-1.5

Step-by-step explanation:

step 1

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-\frac{3}{4} \\point\ (-6,3)

substitute

y-3=-\frac{3}{4}(x+6)

step 2

Convert to slope intercept form

y=mx+b

we have

y-3=-\frac{3}{4}(x+6)

Isolate the variable y

y-3=-\frac{3}{4}x-\frac{9}{2}

y=-\frac{3}{4}x-\frac{9}{2}+3

y=-\frac{3}{4}x-\frac{3}{2}

HELP PLEASE!
Archy [21]

Answer:

Option 2  50 ≤ s ≤ 100

Option 5 She could deposit $50

Option 6 She could deposit $75

Step-by-step explanation:

Let

s -----> amount of money Layla deposit into a saving account

we know that

25%=25/100=0.25

50%=50/100=0.50

so

s\geq 0.25*200 -----> s\geq \$50

s\leq 0.50*200 -----> s\leq \$100

The compound inequality is

\$50 \leq s\leq \$100

<em>Verify each case</em>

case 1) 25 ≤ s ≤ 50

The statement is false

see the procedure

case 2) 50 ≤ s ≤ 100

<u>The statement is True</u>

see the procedure

case 3) s ≤ 25 or s ≥ 50

The statement is false

Because is s ≤ 100 and  s ≥ 50

case 4) s ≤ 50 or s ≥ 100

The statement is false

Because is s ≤ 100 and  s ≥ 50

case 5) She could deposit $50

<u>The statement is true</u>

Because the value of s satisfy the compound inequality  \$50 \leq s\leq \$100

case 6) She could deposit $75

<u>The statement is true</u>

Because the value of s satisfy the compound inequality  \$50 \leq s\leq \$100
