Answer:
A
Step-by-step explanation:
Given the 2 equations
4x + 5y = - 12 → (1)
- 2x + 3y = - 16 → (2)
Eliminate the x- term by multiplying (2) by 2 and adding the result to (1)
- 4x + 6y = - 32 → (3)
Add (1) and (3) term by term
11y = - 44 ( divide both sides by 11 )
y = - 4
Answer:
Statement B, C, E are correct
<u>Solution:</u>
We have to find the true statements
We know that,
To find the diameter of a circle, multiply its radius by two
Thus statement E is correct
Also,
To find the diameter of a circle, divide its circumference by π
Thus statement B is correct
circumference of a circle is obtained by multiplying diameter with pi
The circumference of a circle is greater than its diameter
Thus, Statement C is correct
We know that y-intercepts are the values found when x=0;
1) v²-11v+30=y <-- replace 0 as y and substitute x=0
(0)²-11(0)+30=y
30=y
The y-intercept is 30 here.
2) v²+2v-8=y <-- repeat the above steps
(0)²+2(0)-8=y
-8=y
The y-intercept is -8 here
As you can notice, the c value in the standard equation (ax²+bx+c=y) is the y-intercept.
Hope I helped :)
37.5 is the hypotenuse by using Sin(65)=34/x and shift solve on calculator so you’ll get x=37.5
