Slope is -7, Y-INT is 12

Step-by-step explanation:

We have the eqaution:

y=-7x+12

Which is basically:

y=mx+b (Y = Slope * X + Y-int)

m is slope, b is y-int, using this knowledge you can see that b=12 (y-int) and m=7 (slope)

Given f (x) = 3 x minus 1 and g (x) = 2 x minus 3, for which value of x does g (x) = f (2)?

mrs_skeptik [129]

f ( x ) = 3x - 1

g ( x ) = 2x - 3

_____________________

g ( x ) = f ( 2 )

2x - 3 = 3(2) - 1

2x - 3 = 6 - 1

2x - 3 = 5

2x - 3 + 3 = 5 + 3

2x = 8

2x ÷ 2 = 8 ÷ 2

x = 4

How much did you invest if you earned $131.60 in interest at a rate of 4% for seven years?

Ket [755]

The amount invested is $ 470

<h3>Solution:</h3>

Given that , we have earned $131.60 as simple interest for an amount deposit at the rate of 4% for seven years.

We have to find the amount invested. That is, we need to find the principal sum

Let us use the simple interest formula

The simple interest is given as:

$\text { Simple interest }=\frac{p r i n c i p a l \times \text {rate of interest } \times \text {number of years}}{100}$

Here, simple interest = $ 131.60

Rate of interest = 4 %

Number of years = 7

principal = ?

Substituting the values in formula, we get

$\begin{array}{l}{131.6=\frac{\text { principal } \times 4 \times 7}{100}} \\\\ {131.6 \times 100=\text { principal } \times 4 \times 7} \\\\ {13160=\text {principal } \times 28} \\\\ {\text {Principal }=470}\end{array}$

Thus the amount invested is $ 470

Five less than half the distance from Delaney’s home to the mall is more than 6 miles.

vovikov84 [41]

let x = the distance from Delany's house to the mall

so half the distance would be 1/2x

then it is 5 miles less than that so you would subtract 5 to give you 1/2x-5

and that is more than 6 miles so you get 1/2x-5>6
