Solve this following system by graphing <br> X-y=4<br> X+y=2

OverLord2011 [107]

Answer:

The answer is x = 3 and y = -1

Step-by-step explanation:

If you were to graph the two lines, their equations would be y = x - 4 and y = -x + 2. The two lines intersect at the point (3, -1), so the solution to the system is x = 3 and y = -1.

Please help me solve this math problem

pochemuha

Answer:

(b)

Step-by-step explanation:

A suitable calculator or spreadsheet can find the matrix product for you. Here, the answer choices differ in their upper left term, so we can determine the correct choice by finding the value of that term. It is the dot product of the first row of B and the first column of A.

(5)(3) +(7)(3) +(3)(2) = 15 +21 +6 = 42

This matches choice B.

An angle is 21 degree more than twice its complement find it

jekas [21]

Answer: 67°

Step-by-step explanation:

Complementary angle refers to the angle that when added together will be equal to 90°.

Let the measurement of the angle's complement be x.

Therefore, the angles are x and 2x + 21. Since it's a complementary angle, therefore,

x + 2x + 21 = 90

3x + 21 = 90

3x = 90 - 21

3x = 69

x = 69°/3

x = 23°

Therefore, the angle will be:

= 2x + 21

= 2(23°) + 21°

= 46° + 21°

= 67°

The angle is 67°.

seraphim [82]

Answer:

$r= [(\frac{A}{2500}) ^\frac{1}{2} -1]$

Step-by-step explanation:

Given data

Principal = $2500

time t= 2 years

Required

the rate r

Given the expression for the balance 2500(1+r)^2

Hence

$A= 2500(1+r)^2$

we can make r subject of formula

$r= [(\frac{A}{P}) ^\frac{1}{t} -1]$

$r= [(\frac{A}{2500}) ^\frac{1}{2} -1]$

Hence, for any value of A, we can find the rate using the expression above
