$\large\underline{\bf\red{Solution:-}}$

Given that : h(x) = - x - 1 .

And we are required to find the value of h(-2) .

For this just in place of x replace it by -2 .

So ,

=> h(x) = - x - 1.

=> h(x) = - ( x + 1 ) .

=> h(-2) = - ( -2 + 1 )

=> h(-2) = - 1 × -1 .

=> h(-2) = 1

Hence the required answer is 1

Natalie has 48 tiles write a factor pair for the number 48

grandymaker [24]

A factor is a number multiplied by another factor to get a product:
a x b = c
a and b are factors and c is product.
So, for 48, factor pairs are:

1 x 48
2 x 24
3 x 16
4 x 12
6 x 8
8 x 6
12 x 4
16 x 3
24 x 2
48 x 1

Alright, so let's look at the variables that we have already.
We have P (1500)
We have R (6.75%, .0675 in decimal form)
And, we have A (7300).
So, let's plug this into the formula
A=P(1+r)^t
7300=1500(1.0675)^t
/1500 /1500
4.866...=1.0675^t
Logarithms are the inverse of exponents, (if y=b^x then logarithm with base b of y =x)
So, we know that
t=logbase1.0675(4.866666)
can also put into your calculator as
t= (log4.8666)/(log1.0675)
Thus:
t=24.22569158
This rounds to (in hundredths)
24.23 years.
Looks like a minor rounding issue is all.

What is the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes

Alex_Xolod [135]

Considering the definition of perpendicular line, the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes through the point (7,-6) is -8.

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b

where

x and y are coordinates of a point.
m is the slope.
b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Perpendicular line</h3>

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

<h3>Equation of perpendicular line in this case</h3>

In this case, the line is 7x+2y=14. Expressed in the form y = mx + b, you get:

2y= 14 - 7x

y= (-7x + 14)÷ 2

y= -7/2x - 7

If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of -7/2. So:

-7/2× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (-7/2)

slope perpendicular line= 2/7

So, the perpendicular line has a form of: y= 2/7x + b

The line passes through the point (7,-6). Replacing in the expression for perpendicular line:

-6= 2/7× (7) + b

-6= 2 + b

-6 -2 = b

-8= b, being b the y-intercept of the line.

Finally, the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes through the point (7,-6) is -8.
