One line passes through the points (-7,-4) and (5,4). Another line passes through points (-4,6) and
Kay [80]

Answer:

Perpendicular

Step-by-step explanation:

Let's first get the slopes and see if we can go on from that.

(-7,-4 ) and (5,4) have a slope of : 2/3

(-4/6) and (6,-9) have a slope of : -3/2

This means that they are perpendicular because the slope of line #2 is the reverse and reciprocal of line #1 which follows the perpendicular rule.

The function f is defined by f(x)=-x2+2x-7. What is the value of f(-3)?
Helen [10]

Answer:

Option A f(-3)=-22

Step-by-step explanation:

we have

f(x)=-x^{2}+2x-7

we know that

f(-3) is the value of f(x) when the value of x is equal to -3

so

For x=-3

substitute the value of x=-3 in the equation

f(-3)=-(-3)^{2}+2(-3)-7

f(-3)=-9-6-7

f(-3)=-22

Hello!

I don't exactly understand your question. If you mean to be asking whether or not 1002 is geater than 100, it is.

If you mean to be asking to add it: 102 + 900 + 100 = 1102

Evaluate.
NikAS [45]

The value of the expression [(114−34)⋅(−23)3]÷(−4) is equal to the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4.

<h3>Evaluation for the expression considering PEDMAS</h3>

P – Parenthesis First: B – Brackets First

E – Exponents

D – Division

M – Multiplication

A – Addition

S – Subtraction

We evaluate the expression [(114−34)⋅(−23)3]÷(−4) as follows;

114 - 34 = 79

-23 × 3 = -69

so;

[(114−34)⋅(−23)3] = 79 × −69

[(114−34)⋅(−23)3] = −5451

[(114−34)⋅(−23)3]÷(−4) = −5451/−4

divide through by the common factor −1

[(114−34)⋅(−23)3]÷(−4) = 5451/4

Therefore, the simplified value for the expression [(114−34)⋅(−23)3]÷(−4) is the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4
