Answer:

8

Step-by-step explanation:

we can say that AD is congruent to DC

so your equation for x is: 4x - 1 = 2x

solve this to get x = 0.5

plug x into and equation and multiply you answer by 2 to find the hypotenuse of triangle ABC and DEF

4(0.5) - 1 = 1

hypotenuse: 1 x 2 = 2

since we know x is 0.5, plug this into 4x + 1 to find the length of the leg FE,

4(0.5) + 1 = 3

In the diagram, it shows that the legs of triangle are congruent

this means that FE, ED, BA, and BC are all congruent

since we know FE is 3, we know that all the other sides are 3 as well

this means that the perimeter of the triangle is: leg + leg + hypotenuse

so 3 + 3 + 2

the perimeter is 8

Answer:

[tex]y=-\frac{9}{8} x+7[/tex]

Step-by-step explanation:

The slope is found by doing the equation [tex]\frac{rise}{run}[/tex]. When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal [tex]-\frac{9}{8}[/tex].

The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.

The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!

Answer Yes, because you take the answer from 100+45 and subtract 3 to get to 97 and then you add 29 to make the 47 a 74.

Answer:

82

Step-by-step explanation:

Evaluate 10z² - 2z - 2 where z = 3:

[tex] \longrightarrow [/tex] 10z² - 2z - 2 = 10 × 3² - 2 × 3 - 2

3² = 9:

[tex] \longrightarrow [/tex] 10 × 9 - 2 × 3 - 2

10 × 9 = 90:

[tex] \longrightarrow [/tex] 90 - 2 × 3 - 2

-2 × 3 = -6:

[tex] \longrightarrow [/tex] 90 - 6 - 2

90 - 6 - 2 = 90 - (6 + 2):

[tex] \longrightarrow [/tex] 90 - (6 + 2)

6 + 2 = 8:

[tex] \longrightarrow [/tex] 90 - 8

Answer:

13/13= Slope = 1

Step-by-step explanation:

M=rise/run, So that means 13 down then 13 to the left.

So 13/13 is the slope, but if it is simplified it is slope=1

Answer:

Step-by-step explanation:

We are given three equations to solve. First, let's solve the equations for x.

Equation 1

[tex]\displaystyle{6x+8=7x+13}\\\\7x + 13 = 6x + 8\\\\x + 13 = 8\\\\\bold{x = -5}[/tex]

Therefore, we determined that for the first equation, x = -5. We can check our solution by substituting it back into the original equation.

[tex]\displaystyle{6(-5)+8=7(-5)+13}\\\\-30 + 8 = -35 + 13\\\\-22 = -22 \ \checkmark[/tex]

Since we got a true statement, there are no other values of x for which we get a true statement. Let's test this with the opposite value: positive 5.

[tex]6(5)+8=7(5)+13\\\\30 + 8 = 35 + 13\\\\38 = 48 \ \text{X}[/tex]

Therefore, for Equation 1, there is exactly one solution.

Equation 2

[tex]6 x + 8 = 2 ( 3 x + 4 )\\\\6x + 8 = 6x + 8\\\\0 + 8 = 8\\\\8 = 8 \ \checkmark[/tex]

We get a true statement by solving for x (which ends up canceling out of the equation entirely). Therefore, we can check any value in place of x to see if we get a true statement. For this instance, I will use -3.

[tex]6(-3) + 8 = 2 ( 3(-3) + 4 )\\\\-18 + 8 = 2(-9+4)\\\\-18 + 8 = 2(-5)\\\\-18 + 8 = -10\\\\-18 = -18 \ \checkmark[/tex]

We still get a true statement, so Equation 2 has infinitely many solutions.

Equation 3

[tex]6 x + 8 = 6 x + 13\\\\0 + 8 = 13\\\\8 \neq 13[/tex]

We get a false statement. Therefore, Equation 3 has no solution.

9) B= 115 / C= 65 / D=135 / E= 115 / F=25

10) B= 110 / C= 70 / D=1120 / E=70 / F= 20

11) A= 68 / B= 112 / C= 68 / D=112 / E= 68

12) A= 64 / B=116 / C= 64 / E=64 / F=26

Step-by-step explanation:

9) B= 115 / C= 65 / D=135 / E= 115 / F=25

10) B= 110 / C= 70 / D=1120 / E=70 / F= 20

11) A= 68 / B= 112 / C= 68 / D=112 / E= 68

12) A= 64 / B=116 / C= 64 / E=64 / F=26

Answer:

x = 1

Step-by-step explanation:

3x +2y = 15

y = 6x

Substitute y for 6x in 3x +2y = 15!

3x + 2(6x) = 15

3x + 12x = 15

Combine like terms

15x = 15

Divide both sides by 15

15x = 15

x = 1

Answer:

The statements(s) that could be used in a proof with the reason Corresponding Parts of Congruent Triangles are Congruent (CPCTC) are;

AC ≅ EG

BC ≅ FG

∠CBA ≅ ∠GEF

Step-by-step explanation:

CPCTC is a phrase that stands for Corresponding Parts of Congruent Triangles are Congruent. It can be used as a bases for congruent relationships of corresponding angles and segments, after two triangles have been proven as congruent

Given ΔABC is congruent to ΔEFG, we have by CPCTC;

Side AB ≅ Side EF

Side AC ≅ Side EG

Side BC ≅ Side FG

∠A ≅ ∠E

∠B ≅ ∠F

∠C ≅ ∠G.

After an​ accident, police can use the formula [tex]v=2\sqrt{5L }[/tex] to estimate the​ speed, v, in miles per​ hour, that a car was traveling by measuring the length of the skid​ marks, L, in feet. Estimate the speed of a car that left skid marks 118 ft long. If the posted speed limit is 45 ​mi/h, was the car​ speeding? The speed of a car that left skid marks 118 ft long was about nothing ​mi/h.

Answer:

48.6mi/h, Yes the car was speeding.

Step-by-step explanation:

The speed of the car is given by  [tex]v=2\sqrt{5L }[/tex]

Skid length (L) = 118ft

V= [tex]2\sqrt{5*118}[/tex]

  = 2 [tex]\sqrt{590}[/tex]  

  =  2*24.3

V = 48.6mi/h

Since the speed limit is 45mi/h and the velocity of this driver is 48.6mi/h it is clear that was speeding by 3.6mi/h over speed limit.
