Factor the quadratic expression completely.
2x2 + 7x + 3

[tex]\longmapsto \sqrt{{16} } \\ \\ \longmapsto{4} [/tex]

Answer:

-2

Step-by-step explanation:

First, let's put this in slope-intercept form:

-5y-3x=10

5y = -3x - 10

y = (-3/5)x - 2

The y-intercept is -2.

Answer:

65t - 156

Step-by-step explanation:

use a calculator

Answer:

65t - 156

0.416....

Step-by-step explanation:

first you multiply the 13 out to all the numbers inside the parenthesis

then you divide by 65 to get the answer 0.416 but it will be D.

Answer:

15in

Step-by-step explanation:

Convert the 15 ft to inches (180) and then set up the proportion.\frac{1}{12} = \frac{x}{180}121=180x .  Cross multiply to get that 12x = 180 and x = 15 inches.

Answer:

Answer:

No,

Step-by-step explanation:

y = -5x - 1

y=-3x - 2

y=-5x-1

-26=-5(5)-1

True

now

y=-3x-2

-26=-3(5)-2

−26≠−17

False

It is not a solution to both of them

Answer: 106 tickets.

Step-by-step explanation:

Option B is correct that is false.

We have been given a figure we need to tell that the two lines are perpendicular.

Lines are perpendicular if they meet at the right angle.

Line CD is perpendicular AB to vice-versa is not true.

Hence, Option B is correct

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .

The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other.

Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.

Hope this Helps!!!

Answer:

The answer is 19.25

Step-by-step explanation:

Key skills needed: Fraction operations, decimal conversion

1) We are given the hint to use 9 as "b", and we get:

---> [tex]a = \frac{16}{8}(9) + \frac{10}{8}[/tex]  

Let's do  [tex]\frac{16}{8}(9)[/tex]

--> [tex]\frac{16}{8}[/tex] is the same as [tex]16[/tex] ÷ [tex]8[/tex]

16 divide by 8 is 2.

2) This means that it would be  ---> [tex]2(9)[/tex]  which is simply 2 times 9.

2 times 9 = 9 + 9 = 18

3) With that result, it would be  ---> [tex]a = 18 + \frac{10}{8}[/tex]

Now, do [tex]\frac{10}{8}[/tex] (10 divided by 8)  ---> Get 1.25

4) 18 + 1.25 = 19.25, so --> [tex]a = 19.25[/tex] is the answer

Hope you understood and have a nice day!!   :D

Answer:

The interest is 450 ⇒ C

Step-by-step explanation:

The formula of the simple interest is I = Prt, where

∵ Birr invested 2500 at 6% simple interest per annum for 3 years

∴ P = 2500

∵ r = 6%

→ Divide it by 100 to change it to decimal

∵ 6% = 6 ÷ 100 = 0.06

∴ r = 0.06

∴ t = 3

→ Substitute them in the formula above

∵ I = 2500 × 0.06 × 3

∴ I = 450

∴ The interest is 450

Answer:

scalene and right

Step-by-step explanation:

it's a scalene triangle because all the sides have different lenghts. it's also a right triangle because of the square indicating that the triangle has a 90 degree angle making it a right triangle.

Answer:

Any real number strictly larger than 9 and strictly less than 21.

Step-by-step explanation:

By triangle inequality, the sum of the lengths of any two sides are greater than the length of the third side.

We therefore could set up three inequalities.

x+6>15, x+15>6, 15+6>x

Solving these, we get x>9, x>-9, x<21 i.e. 9 < x < 21.

Answer:

2

Step-by-step explanation:

y^m x y^n = y^m+n

so y^-4 x y⁶ = y^-4+6

-4+6=2

NOTE: ^ means to the power of

e.g: y^2 is y² :)

Answer:

126

Step-by-step explanation:

In order to find the initial number, we need to create the expression that is being mentioned and solve for the initial value by applying the opposite expressions to isolate the variable.

(((x / 42) * 8) + 10) = 34   ... subtract 10 from both sides

((x / 42) * 8) = 24 ... divide both sides by 8

(x / 42) = 3  ... multiply both sides by 42

x = 126

Finally, we can see that the initial value was 126
