Tell whether the ordered pair is a solution of the system of equations. Y=3x-3 Y=-x+5 (3,6)

Answer:

what is the question? Please ask a question.

Answer:

y = -3x - 2

Step-by-step explanation:

Since the line passes through the point (0, -2), -2 is the y-intercept

Using the slope-intercept form for a line we have

y = -3x - 2

Answer:

if x is an unknown number you know that it is 6 more than the unknown number

Answer:

90 : 135 : 225

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 + 5 = 10 parts

Divide the number by 10 to find the value of one part of the ratio

450 ÷ 10 = 45 ← value of 1 part of the ratio, then

2 parts = 2 × 45 = 90

3 parts = 3 × 45 = 135

5 parts = 5 × 45 = 225

Then

450 in the ratio 2 : 3 : 5 is 90 : 135 : 225

The answer will be C

Step-by-step explanation:

Answer:

x = 26

Step-by-step explanation:

it is a right angle so

(x+4)3=90

3x+12=90

-12         -12

3x = 90-12

3x = 78

/3       /3

x = 26

Answer:

The vertical intercept is 5y. The slope is 1/2

Answer:

12-issue subscription

Step-by-step explanation:

18-issue sub = $40.50 ÷ 18 = $2.25/issue

12-issue sub = $33.60 ÷ 12 = $2.8/tissue

=> The 12-issue subscription costs more per issue (2.8 > 2.25)

Answer:

so you would divide the cost by the issue

the 18 issue is $2.25 per issue

the 12 issue is $2.80 per issue

the 12 issue costs more

1.one solution

2.one solution

3. no solution

4. infinitly solution

Step-by-step explanation:

Answer:

We have to find the product of ,

(a+3)(a-2)

We will use the identity

(x+a)(x+b)=x² + (a+b)x+ab

So, (a+3)(a-2)=a²+(3-2)a+ (3)×(-2)

       = a²+1 × a -6

       = a²+a-6

Or , you can use the following method, to find the product.

a×(a-2)+3×(a-2)

=a² -2 a + 3 a-3×2

=a²+a-6

Answer:

152

Step-by-step explanation:

the second one, ((6 x 5) x 4) +((5 x 4) x 2) = 160

the third one, ((7 x 6) x 4) + (6 x 4) x 2) = 216

the fourth one, ((8 x 4) x 4) + ((4 x 3) x 2) = 152

Answer:

Step-by-step explanation:

distribute:

-5a+30+6a

simplify:

a+30

not sure what u mean by coefficient, the coefficient of a is 1.

Answer: a + 30

Step-by-step explanation:

Using the distributive property, we can figure out the expression unsimplified = -5a+30+6a

By combining like terms, -5a+6a = a

Therefore, this expression = a + 30

Answer:

It began after the stock market crash of October 1929, which sent Wall Street into a panic and wiped out millions of investors. Over the next several years, consumer spending and investment dropped, causing steep declines in industrial output and employment as failing companies laid off workers.

Answer:

22

Step-by-step explanation:

3n + 4^2

n = 2

3(2) + 4^2 = 6 + 16 = 22

Solution :

The amount invested by Yvonne = $ 4,000

Time of investment = 3 years

The simple interest earned by Yvonne in 3 years = $ 960

a). Therefore, the amount Yvonne earned by the end of three years is

= principal + interest earned

= 4,000 + 960

= $ 4,960

b). The formula for simple interest(S.I.) is given by :

   [tex]$S.I. =\frac{P.T.R}{100}$[/tex]

  or [tex]$R = \frac{SI \times 100}{P.T}$[/tex]

          [tex]$ = \frac{960 \times 100}{4000 \times 3}$[/tex]

          = 8%

c). Now if the interest rate is 1% greater, i.e. R = (8+1) = 9%

   ∴ [tex]$SI =\frac{P.T.R}{100}$[/tex]

      [tex]$SI =\frac{4000 \times 3 \times 9}{100}$[/tex]  

      SI = $1,080

Therefore, the amount at the end of 3 years with 9% rate of interest will be

  = 4000 + 1080

  = $ 5080

Thus, Yvonne will have 5080 - 4960 = $ 120 money more in her account if the rate of interest was 1% greater.

Answer:

X=14

Step-by-step explanation:

We know that both sides are congruent

so if the other angle is 7- then divide 70 by 5

Hope this helps ^-^

Step-by-step explanation:

step 1. a quadrilateral has 4 sides and 360° internally.

step 2. 70 + 5x + 110(2) = 360.

step 3. 5x = 70

step 4. x = 14.

Answer:

Number of terms = 3

Degree = 6

Step-by-step explanation:

A polynomial is a mathematical expression that gives the detailed combination of variables with their coefficients, their positive exponential, and other variables using the operations of subtraction, addition, and multiplication

The number of terms in a polynomial is the number of different powers of added or subtracted in the expression

Therefore, the number of terms in the expression -3·s⁶ + 2·s⁴ + 3·s³ is 3 terms

Number of terms = 3

The degree of a polynomial is given by the highest power of the variables in the polynomial. Therefore, the degree of the given polynomial is 6

Degree = 6
