Answer:

Answer:

\huge{ \boxed{ \bold{ \tt{41}}}}

Step-by-step explanation:

\text{Given} :\text{d \: = 7 \:, e = 3}

\text{To \: find : The \: value \: of \: given \: expression}

\text{Solution : }

\text{4d + 9e - 14}

Plug the value of d and e

\text{⇢ \: 4 ∗ 7 + 9 ∗ 3 - 14}

Multiply the numbers

⇢ \text{ \: 28 + 27 - 14}

Add the numbers : 28 and 27

\text{⇢ \: 55 - 14}

Subtract 14 from 55

\text{⇢ \boxed{ 41}}

Hope I helped!

Best regards! :D

Express 144 as the product of the prime factors

Answers

144 ends in an even number, so we know we can divide it by 2.

144 = 2 × 72

Let's keep going. 72 can be divided by 2 again.

144 = 2 × 2 × 36

And again...

144 = 2 × 2 × 2 × 18

And again!

144 = 2 × 2 × 2 × 2 × 9

And 9 equals 3 times 3.

144 = 2 × 2 × 2 × 2 × 3 × 3

Since we have a bunch of numbers multiplying into themselves, we should use exponents to write this.

\boxed{2^4*3^2}

(The little number above, called an exponent, tells you how many times to multiply the number by itself.)

A line has slope –5(over)3 . Through which two points could this line pass? (1 point)(12, 13), (17, 10)
(16, 15), (13, 10)
(0, 7), (3, 10)
(11, 13), (8, 18)

Answers

The points of the line that has a slope of -5 over 3 is (11,13) (8, 18). This can be computed using the formula of finding the slope of a line which m = y2-y2 over x2-x1. This is computed as follows:

m = 18-13 over 8 - 11
m= 5 over -3 or simplified to m= -5 over 3

Answer: Rate of Change and Slope Quick Check

C. -1/3

D. (11,13) (8,18)

B. -2

D. Undefined

Help solve with subsitution x+y=1, 2x+3y=-4

Answers

{   x + y = 1    * ( - 2 )
  2 x + 3y = -4

- 2 x - 2 y = - 2
  2 x + 3 y = - 4
_______________
         y = - 6

Subsititute y = - 6 

2 x + 3 y = - 4

2 x + 3 * (-6) = -4

2 x - 18 = - 4

2 x = - 4 + 18

2 x = 14

x = 14 / 2

x = 7

The solution  to the system of equations are:

x = 7 and y = - 6

hope this helps!

GEOMETRY. PLEASE CHECK MY ANSWER! THANKS.Mario’s company makes unusually shaped imitation gemstones. One gemstone had 12 faces and 10 vertices. How many edges did the gemstone have?

A. 23 edges
B. 22 edges
C. 25 edges
D. 20 edges****

Answers

I'd solved it in the pic, and the answer is D. 20
This is simple.
we should have a knowledge of the Euler's Theorem/Euler's Formula
F+V=E+2
Basically states that:
# of Faces+ # of Vertices= # of Edges+2
12 + 10 = E + 2
(-2) + 22 = E + 2 (-2)
           20 = E

Yep, The answer is D. 20 edges
